Henan oil-fired boiler Introduction Product Introduction: Henan oil-fired boiler to run than electric heating boiler economic, easy to use than gas-fired boiler. With economic development and social progress and the improvement of people's awareness of environmental protection, coal-fired boilers due to serious pollution, moving away from sight, replaced by a new environmentally friendly digital boiler, such as electric heating boiler, oil boiler, gas boiler, electric heating boiler is more expensive, gas-fired boilers need to open a gas pipeline, then, if there is no gas pipeline, and hope boiler low operating costs, only select oil-fired boiler. Boot check: 1, various instruments, whether the instrument to confirm the adequacy of fuel tank, and the inlet valve is opened. 2, confirm the soft capacity and the water tank boiler water quality meets the requirements of the main valve is opened and boiler feed water inlet valve. 3, rotation of the oil filter to remove debris. 4, drain the remaining water in the boiler, while the opening operation of the low level alarm and chain. Features: 1, inserted within a fire retardant spoiler tube, slow speed exhaust enhance heat transfer, the temperature of the flue gas discharged from a low smoke chamber, reducing heat loss and save fuel. 2, furnace by computer-aided design, each of the heating surface is optimized, compact and reasonable arrangement, small boiler area, high thermal efficiency. 3, the user can set the start, shutdown time, after setting, no special duty, easy, and effort. 4, according to the boiler pressure furnace design, furnace provided with a top opening to atmosphere, the boiler is in an unpressurised state, there is no risk of explosion. 5, the inner fire tube inserted spoiler retardant, smoke slow speed, to strengthen the heat exchanger, combustion heat is conducted to a large extent in water, the discharged flue gas temperature is low smoke chamber, reducing heat loss and save fuel. 6, the water level sensor water level real-time monitoring, to continuously monitor the water level is normal furnace. While controlling the temperature and replenishment level sensor solenoid valves, the boiler water may be continuously supplied. 7, water boiler fuel water speed, water volume, widely used in factories, hospitals, schools, etc. required a large amount of boiling water units. Shutdown procedure: 1, when it is desired to deactivate the combustion boiler to the switch in the OFF position, the oil supply is stopped, the flame is extinguished, but the fan is still operating to blow away the residual flue gas in the furnace. 2, when the blower is stopped, the operation OFF switch to turn off the power and then, after closing the steam valve, and the fuel supply valve to close the valve. 3, open the drain valve when the discharge pressure is reduced after the boiler play an open valve, to drain the water in the boiler, and the steam partial open the drain valve to drain the water in the drum segregation. Daily checks: 1, check the water level regulator function: whether the automatic water pump stops. 2. Check flame monitoring. 3, is rotated, the slide cam portion lubricating, and wiping. 4, the flushing water level gauge 1-2 times (class), according to the proper operation, so that until the rinse water level gauge. 5, sewerage 1-2 times (class).

1: Steam boiler steam pressure the higher the better selection pressure, depending on the user's requirements. Vapor pressure, safety pressure member Advantageously, the energy consumption is low; but the steam will be relatively worse quality, low enthalpy, humidity, may be difficult to meet the disinfection, sterilization, culture, heating and power needs. And the high vapor pressure, energy consumption is high, the corresponding steam equipment, piping and valves the pressure is high, the maintenance requirements are also more, the production of steam, the heat transfer process, a large leakage loss. Meanwhile, high-pressure steam as the steam pressure is increased to carry the increased salinity, so salinity these waterwall tubes, pipe tobacco, and other drum heating surface fouling, overheating, foaming, clogging even increase the possibility of squib. Salt steam to steam turbine flow area will decrease, reducing the efficiency and seriously affect the heat transfer. Thus, fireman must operate in accordance with operation of the steam pressure, the steam pressure fluctuations generally allows a value between 0.05 ~ 0.15MPa.

2: the higher the boiler water level was considered safe water level is higher, the boiler water is not easy, security is also guaranteed. In fact, this is a misconception, the water level is too high, steam and humidity increase, poor steam quality, steam equipment will harm and production results. Industrial boilers, a moisture vapor sterilization or incubation with a large amount of steam also increased salt, or culture for a long time ranging from sterilization, steam consumption increase, ineffective, decreased production culture; weight is not reached the purpose of disinfection or cultured biological products contaminated scrap, even pipes, water hammer occurs apparatus. For utility boilers, steam moisture capacity, the steam turbine last stage blades will be erosion, there may appear Priming pot, water shock severe enough to cause harm equipment and personal safety. Thus, the pot water level should be maintained within a fluctuation range of ± 50mm well.

3: Some people think the better fuel plus fuel plus the more productive the greater the amount of steam. Little do they know too much fuel into the furnace, the effect will be counterproductive. When a certain amount of air and the excess amount of fuel, the furnace will produce a large amount of incomplete combustion, resulting in energy waste. People often see the dark furnace flame, weakness, and black smoke chimney, mostly for this reason. In severe cases, there will be fire pulverized coal, oil furnace secondary combustion occurs, burst pipes until shutdown. Therefore, the ratio of fuel and air volume should be adjusted appropriately, typically by looking at the fire, smoke color look, see table indicates the amount of oxygen determined. When the flame in the furnace as a bright yellow, pale gray smoke chimney to take, stable vapor pressure, wind coal showed appropriate ratio, good combustion.

4: Dial stirring the fire, the better the fire is commonly used in industrial boilers manual method. By stirring the fire, can be eliminated crater, reduction furnace from the fire and the fire bed smooth, homogeneous combustion, strong. But too much stirring the fire, but will reduce the overall thermal efficiency; this is because when stirring the fire, a lot of cold air into the furnace, reducing the average temperature of the furnace section of the flame. At the same time, increase the heat losses, an increase in the number of black smoke chimney, pollution of the environment. In addition, when stirring the fire, the staff is also susceptible to flame radiation, burns, fire-resistant layer is also susceptible to dial hearth fire damaged tools, increased furnace building maintenance workload. Therefore, the fire should be allocated as needed, to minimize the appropriate dial.

5: the bigger the better furnace pressure and furnace pressure is reflected in one of the boiler combustion conditions is normal or not an important parameter. Operating the boiler furnace negative pressure should be maintained between 10 ~ 20Pa, too great a negative pressure results in: increased leakage furnace, heat losses increase; wind increased electrical energy consumption; fly ash increased the wear along the heating surface; reduced the furnace heat of combustion efficiency. Most gas-fired boiler designed to run slightly positive pressure to increase the combustion rate. Operation, the furnace pressure becomes positive, even increasing the wind is still difficult to maintain the chamber negative pressure, said system failure or the wind furnace wall tubes, superheaters and other soft drinks leakage; fire furnace, the furnace pressure is first reflected table violent swing to the negative direction flung head. Therefore, the furnace pressure must be run according to the provisions, or should pinpoint the cause.

6: sewage longer the better spoken here regularly refers only to the sewage discharge rather than continuous blowdown. Periodic sewage mainly refers to the existence of negative bottom of the boiler slag, dirt and corrosion products, reduce furnace tube fouling, prevent clogging and reduce the salt content of the water boiler, heat transfer enhancement effect. One would think that the longer the discharge time, impurities will be discharged bottom of the pot the more, the better sewage, it is not. Sewage long time, a waste of a lot of heat, affect heating steam pressure; two pairs of boiler water circulation unfavorable, water wall tube burst will occur in severe cases. Thus, the sewage must be periodically according to "ground discharge, the discharge less uniform row" principle, provided hand operation. General Provisions at least once every eight hours of sewage, sewage each time shall not exceed 30s, overtime is strictly prohibited.

Solutions and prevention of gas oil-fired boiler flameout Today we'll resolve what about gas fuel boiler flameout solutions and prevention fuel gas-fired boiler flameout Solution: First, the furnace pressure gauge indicates the value suddenly increases, the furnace black can not see the flame, burning furnace sounds disappear, extinguishing the flame supervision devices emit a signal; the temperature dropped sharply atmospheric pressure, the water level dropped after the first rise, and so are flameout phenomenon. Auxiliary flame caused by an accident, such as a fan, blower power interruption, there is an accident signal emitted; fuel supply as a result of intermittent, the boiler is oil or gas pressure drops to zero, only a single burner flame, the furnace may also be thrown skew central flame extinguished burner pressure change; as a result of the fuel supply interruption, the extinguished burner pressure or hydraulic indication may drop to zero, and the fuel consumption, the gas pressure is increased other operating burner. Causes gas boiler flameout are: sudden increase in gas pressure caused from the fire, the solenoid valve malfunction the gas supply interruption, the gas composition has changed so much moisture content is too high and so on. Blower, fan failure, the load is too low furnace pressure is too large excessive leakage and other excessive wind, so that the furnace temperature is too low can also cause the boiler flame. Cause misfire has oil-fired boiler: oil pump failure, the oil surface is exposed inhalation tube, clogging of the oil filter or oil supply pipe, a solenoid valve malfunction or misoperation caused by oil running intermittently. During transport the fuel with steam by heating water; inappropriate position inhalation tube with the pumping of water; improper contaminated oil floating on the water; poor dewatering tank drain plug such that the fuel with water. After the explosion should be taken to prevent the furnace boiler flameout, it must immediately cut off the fuel supply to the furnace, and then block the electromagnetic valve of the gas supply valve to seal off the fuel supply to run the burner. When the action to be fast in order to avoid inheritance or restore fuel supply during operation, causing the furnace explosion. And identify the cause of boiler flameout troubleshooting find a good job and then start the preparatory work. Before starting the boiler should be enhanced ventilation purge, purge time is more than 5min, then procedures ignition. It is forbidden to send fuel directly to the high-temperature furnace without using an ignition spark ignition device to prevent furnace explosions. If due to fan failure caused when the flame should be quickly cordoned off the fuel supply line of each valve, with special attention because the valve is not tight blockade caused by leaking fuel. Ventilation and purging of the furnace and flue in accordance with the approach of an emergency shutdown. Ignition step by step in the recovery operation after the fan. Single burner flame burner only block the fuel supply valve, the burner off a small damper identifying and troubleshooting and then re-ignition by the ignition process. Boiler flameout of prevention: For oil-fired boiler should minimize the possibility of fuel transport, storage and handling of water in all sectors. Tank initiative measures should dehydration and dehydration on schedule. In any case, it should ensure the security of oil supply. The supply of oil and acceptance testing, cutting oil change when the master species. When a large change in oil types, varieties and the need for the oil tank to store the original varieties contaminated test to determine whether the same storage tank, to prevent the density and viscosity differences between a large number of decomposed oil mixed insoluble material, clogging oil pipeline. For the operation of the gas boiler should be closely monitoring the evolution of gas pressure, the timely processing of exceptions thrown up air pressure, ensure the supply pressure in the normal range. To always understand, repair gas composition, gas composition changes when large, to take the necessary adjustment measures on the boiler operation.
