Recently, in Qinghai Province Jigzhi County Market Authority carried out a special inspection of boiler safety within the county, mainly in order to further strengthen the special equipment safety supervision, investigation and potential risks.

County Market Authority was held on June 8 special meeting to make arrangements for this special inspection work; the meeting, Secretary of this special inspections put forward specific requirements: Either the county government and relevant departments in accordance with the superior, all in the area to check boilers, boiler and disabled to look back, to verify the implementation of the rectification; the second is to designate a person to carry out checks to ensure that this special inspection into effect, produce results; the third is to check violations found to be severely dealt with according to law.

Subsequently, according to the spirit of the meeting, Jigzhi County Market Authority Board redoubling its efforts to carry out special inspections. 5 out of law enforcement officers were examined using 10 units. The county has been reported to stop the boiler After registering with and eleven inspection and verification. Focus on checking whether the boiler inspection, whether the registration, check whether safety accessories in place, whether fireman certificates and other issues, focusing on correct pressure boilers, waste heat and pressure tanks and other equipment as well as the use of pressure boiler overpressure operation and other illegal operations behavior, found hidden among all checks for disposal in accordance with law, to ensure the safe operation of the boiler county.

Next, the county will further increase the pressure in the boiler with supervision and do routine inspections and safety management, strengthen the use of units to pay a return visit found the problem of checks put in place to promote the use of the unit responsibility, and earnestly safeguard the life and property Safety.

Coal-fired best coal steam boiler in guam scale can cause harm and failure scale is the first coal-fired steam boilers, coal-fired steam boiler is the main cause of the accident, the danger main problems: wasting a lot of fuel: Because the thermal conductivity of the scale of only a few steel one tenth, so that the heating surface when the fouling of heat transfer will hindered, in order to maintain a coal-fired steam output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now can be used efficient and environmentally non-corrosive cleaning agent fired steam cleaning, expose the metal tube so that the device primaries, and to reduce biological fouling of algae because silt impact. While the peeling effect of iron on the iron oxide and ethylene, prolong the service life of coal-fired steam boilers, to reduce energy consumption and improve productivity. Fired steam after a long run, the inevitable emergence of scale, the problem of corrosion, scale coal-fired steam boiler formation is mainly due to the water with hardness components, high temperature, high pressure after continuously concentrated by evaporation, the coal-fired steam furnace with a series of physical, chemical, and finally heating surface to form a hard, dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, leads to a reduction endothermic coal-fired steam boiler waterwall furnace, burning coal steam boiler furnace exit temperature increases, the increase in the loss of coal-fired steam boilers. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of coal-fired steam boilers.

Several factors underlie the vertical best coal steam boiler in guam efficiency China has been working to catch on coal to natural gas, vertical steam boiler with greatly reduced contamination of dust, smoke and other effects of a nitric oxide gas has also been healthy curb. Efficiency is an important indicator of a measure of vertical steam boiler, a good number of factors under the topic to discuss the direct impact of vertical steam boiler efficiency began. After analysis of stakeholders, heat loss from vertical steam boiler contains two pieces: the proportion of full combustion air with flue gas emissions unreasonable heat loss. Heat loss can be reduced smoke emission can be installed at the end of the vertical steam boiler stack waste heat reuse install, or more leading system with condensing boiler. Combustion air ratio sufficient unreasonable faults into: general vertical ejector-type steam boiler burner selection, resulting in a motor fuel ratio can not be adjusted. Most of the selected vertical steam boiler is mechanically strong emission combustion engine, air-fuel ratio resulting irrational factors are the following: air-fuel ratio can be divided into two reasonable chance comprising: when the air in excess, the excess will have full cold It is heated, resulting in increased operating costs vertical steam boiler, steam boiler efficiency vertical drop; when the air is not enough, will produce insufficient burning phenomenon, caused by vertical steam boiler efficiency.

Steam boiler accident type and processing method, and use common sense safety boiler best coal steam boiler in guam accident type and processing method, overpressure accident 1 boiler, boiler overpressure phenomenon of (1) a sharp rise in steam pressure, exceeds the allowable working pressure gauge pointer over " red line "safety valve after the pressure is still elevated. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Second, an accident boiler water, boiler water shortage (1) below the minimum safe water level line, or can not see the water level, the water level gauge glass (plate) as a white. (2) as a full-color water level gauge vapor instruction color. Low water level alarm signal (3) water level alarm occurs. (4) low water interlocking means, the water level should be below a prescribed value blower, Fan, grate reduction motor stops running. (5) a sharp rise in the superheater steam temperature, higher than the outlet steam temperature. (6) boiler exhaust gas temperature rises. (7) the water flow is less than the steam flow, causing Should the water tube due to tube cracking or economizer, an opposite phenomenon occurs. (8) When a serious water shortage, can smell the burnt smell. (9) When a serious shortage, the door can be seen from the red-hot waterwall tubes. (10) a serious water shortage, the furnace tube may rupture, then can hear the explosions, smoke and steam from the door, watching spray the fire door. 2, boiler water treatment (1) through the "waters", sentenced to severe water shortages, emergency shutdown must be prohibited blind to the boiler feed water. (2) through the "waters" sentenced to a slight lack of water, it should reduce fuel blast, the wind, and slowly feed water. Third, full water boiler 1 accident phenomenon (1) above the maximum allowable water level line, or can not see the water level, the water level gauge glass (plate) dark color boiler filled with water. (2) all of the water phase as a color level gauge indication color. High-water alarm signal (3) water level alarm occurs. (4) decreased superheated steam temperature. (5) water flow is not normally greater than the steam flow. (6) water in a large number of sub-cylinder, severe trap operation. (7) with a large amount of water steam severe, increased salinity, water hammer occurs in the sound of the steam pipe, the steam connection flange outwardly dripping take place. 2, boiler full of water treatment rinse water table, determined to be minor or serious full of water full of water. Method: Close water table, the water pipe connected cock, then open drain cocks As can be seen from the decreased water level, indicating a slight full of water, the water supply is stopped, the drain valve open, put to the normal water level. Such as severe filled with water due to take emergency shutdown measures.
