gas vertical steam heating boiler

Spark ignition rods gas vertical steam heating boiler, but because the misfiring spark ignition rods gas boiler misfiring but the reasons: 1, the cyclone disc space ventilation is blocked carbon, poor ventilation. 2, dirty oil nozzle clogging or wear. 3, the throttle angle is set too small. 4, the firing bar from the leading edge from the oil nozzle tip inappropriate (too protruding or retracted) 5, the first solenoid valve is an oil debris blocking gun (gun small kerosene). 6, oily or too viscous to flow easily clogged or the oil filtration system the valve is not opened, so that insufficient suction pump, oil pressure. 7, the filter pump itself blocked. 8, the oil more water (boiling abnormal noise within the heater). Gas boiler ignition spark rod action but misfiring are: clear; the first washing, such as not renewed; turndown test; adjusting the distance (in 3 ~ 4mm as well); Remove cleaning (cleaning the parts diesel) ; For more information about oil oil oil, information technology please pay attention to the public number of oil rings. Check the pipeline and oil filters, insulation equipment; peripheral screw pump removed, carefully remove the cover inside out net oil, diesel oil immersion; renewal of the test oil. When the gas boiler and turn the fire a small fire normal, off, or flashing the causes of instability: 1, air volume damper setting fire too. 2, oil fires micro switch valve (damper outermost that group) inappropriate setting (set throttle air flow rate is greater than the fire). 3, oleaginous easy to spray viscosity is too high (heavy). 4, and the nozzle plate spacing cyclone inappropriate. 5, fire nozzle worn or dirty. 6, the preliminary fuel tank temperature is too high, so that the steam not smooth oil pump oil feed. 7, gas hot water boiler fuel oil water. When a small fire gas boiler normal and turn the fire extinguished or flashing instability action: Test gradually reduced; heating temperature; adjusting the distance (between 0 ~ 10mm); clean or replace; i.e., set to about 50 deg.] C may be; or drain oil change.

Successful ignition of fuel steam vertical steam heating boiler can not run, because of those common oil gas powered steam boiler applications, all of you should ignite the fuel steam boiler in the application process, no way ignition is also the most common problems. Fuel steam boiler in the application process, most likely resulting in no way ignition, resulting in fuel steam boiler can not run normally, small series to introduce you to a steam boiler does not ignite the fuel to run those common reason. Fuel steam boiler can not run common ignition of those reasons: First, the ignition problems: pulse ignition and control systems such as the one of which has caused the problem, the fuel steam boiler can not start. Second, the battery thing: to be very important to see if the battery is a battery in the end is not too aging. The charge is not standard, the same can not let steam boiler fuel ignition. Third, the water pressure thing: at the inlet steam boiler fuel filters block the formation of water can not flow normally through the clean up clean ok. Fourth, the pulse valve problems: If the boiler ignited fuel vapors to ignite division saw sound, no pulse valve "despair" squeak, probably for the pulse valve is damaged or degraded, pulse valve degeneration, will not manipulate, the beginning of the ignition operation when closing a flow will hit a fire, but the fire immediately and confinement; pulse valve before confirm whether there is a problem to confirm whether normal ignition actuating member, if the fault can not pull the valve actuating pulse. V. ignite feelings needles or needle thing: fuel steam boiler ignited hand shift. You can change or correct the ignition pin arrangement; if feelings of degradation promise things, as long as the feeling wiped clean arranged on it. Six, usually no way to exhaust smoke tube. Smoke tube steam boiler with a fuel block, clean breathing tube blockers smoke tube is too long, the configuration is not correct. Referring may be configured to inform two coaxial cigarette heater tube. VII vapor setter joint problems: fuel steam boilers, water vapor degradation intimal flap valve or joint damage, not the weak control push button switch; weak bad control switch button.

Coal-fired vertical steam heating boilers to gas-fired boiler and the basic requirements of a program, the transformation of the basic requirements: 1, the boiler must be carried out in accordance with "Steam Boiler Safety Technology Supervision" and "Hot Water Boiler Safety Technology Supervision" and relevant national technical regulations, construction program should be sent to the local technical supervision departments for approval. 2, to determine the value in use based on the transformation of the boiler has the age and state of the art, taking into account the life expectancy of the boiler. If the boiler use a longer useful life, and the pressure there is a serious corrosion, scaling and overheating phenomena such elements, no transformation of value. 3, boiler walls, chimneys, water supply and air supply, the wind system should remain largely intact. 4, after the transformation of the original technical parameters should be kept constant boiler (operating pressure, temperature, etc.) or the load and to improve the efficiency of the original boiler. 5, after the boiler should comply with national environmental and technical indicators, solve the problem of smoke and dust, meet environmental requirements. 6, when the boiler should try not to change the original pot, and the body is pressed by the original system architecture, covers the smaller the better. 7, rehabilitation programs should be simple, low investment, short construction period and quick, safe and reliable. Second, the transformation method: 1, removal of the original coal-fired boiler slag machine, equipment on coal, dust, chain grate and gearbox. 2, according to the diameter and length of the flame, furnace installation height determining geometric dimensions and the burner. 3, making the furnace, the furnace bottom refractory brick, a semicircular shape. 4, the front arch openings mounted burner nozzle. 5, after that the flame away from the center position of the tube the arch, the arch of the pipe on the basis of the original slope, heightening baffle wall, the protective tube arch. 6, install blast doors. 7, install the induced draft fan drive. 8, the body of the boiler water test pressure 1.5 times the working pressure. 9, the automatic control system installed. Third, the technical proposal: 1, furnace design should consider the flame length and diameter of the flame of the combustion gas, so that the furnace space is filled with the best of the flame, the flame not Wall flush. 2, as the main component of natural gas CH4, H20 generated after combustion, steam share large, so that strong radiation, heating furnace suitably increased to take advantage of the radiation heat transfer, thermal efficiency, reduce the consumption of steel, ensure that the boiler output, and may increase the boiler output. 3, a slight positive pressure within the boiler furnace using a combustion or slightly negative pressure, the sealing performance of the boiler furnace walls to strengthen, not air leakage. 4, due to the smaller excess air ratio of the gas boiler, combustion requires less air flow, coupled with the removal of dust, dust and small flue system, the flue resistance is reduced, a large surplus primer fan flow, using file when the damper plate adjusting the power loss is large, frequency control can be induced draft fan air volume regulation. 5, after the furnace door and see the fire smoke chamber above the chimney, mounted two proof doors, in order to improve the antiknock performance of the boiler. 6, the boiler flue gas the volume of gas in the vapor component is generally 15% to 19%, well above the coal-fired boiler flue gases generated in the water vapor content of 6% by volume or less. Boiler shutdown and startup, due to the low wall temperature of the boiler heating element, when less than less 50 ℃, the flue gas water vapor dew condensation on the wall will, if not removed condensate with the condensate of the contact wall would be C02 acid gas corrosion of furnace wall and the insulation material due to water absorption and thermal insulation effect will be lost. Therefore, before and after the gas hot water boiler smoke box and the rear box and the rear flue smoke condensate discharge means to be provided, promptly boiler condensate removal. 7, the gas boiler-system control function should have combustion process. Pre-blowing may be implemented, auto-ignition, flame detector self-test, automatic load adjustment, flame monitoring, fault alarm interlock shutdown, the gas leak detection valve, induced draft fan and burner control sequential chain protection. 8, in order to prevent fluctuations in the gas pressure regulator to meet the burner requirements, the installation of a gas regulator metering panel outer gas inlet in the boiler room, the surge counter can be accomplished by filtration, regulating, metering, safety shut-off functions.
