Check the bottom front of the hot water boiler to run fast boiler Henan small series for you to explain examination before the boiler 1, containing internal furnace inspection and application plans. 2. The stove and flue testing, stove and chimney soot and dirt should be removed. Gas hot water boiler with environmental protection, energy saving, Security Council, distinctive features automatic operation, it is very convenient application, and the other, since the operation of the tertiary industry, the New Deal judiciary incentive, gas hot water boiler increasingly suffered everybody pro-Lai. Adjustments for door ventilation ducts and flues, make sure the door is detailed and inseparable, knobs sure is handy, turned on and off label MUST be accurate. 3. Note the furnace to carry out inspection, inspection Security Council notes the situation is not good; the cock is not rotating flexible, convenient; all kinds of righteousness tables and handling equipment should be complete, fine, clean up. According to post-test, pressure gauge cocks should be in attitude. 4. The inspection system of process control. Boiler Biomass: Biomass vertical boilers, biomass boilers pillar. Biomass gas thermal oil heaters, biomass morocco fired steam boiler, biomass hot water boiler, biomass oil furnace. 5. inspection auxiliary facilities. Such energy conversion is steam boiler facilities, the kinetic energy of the oil in the heating furnace has a type of chemical energy, electromagnetic energy, heat energy, etc. smoke, and after converting furnace, must be provided externally output energy vapor, hot water, or inorganic heat carrier. 6. check combustion equipment, look at the ignition device is not a good situation; for the gear system, coal handling systems, ballast systems, brake test, no problem; Security Council spring gear box should be properly gripping and Moist; coal door right foot mark. Eagle iron neat detail, detail ballast plate, flexible pump power. 7. The auxiliary heating surface inspection, inspection aids (booster fans, pumps, etc.) coupled strong coupling; moderately loose belt; ample grease excellent; circulating cooling water smooth. According to the test, the protective cover mounting Security Council, an independent test run, deceleration always pay attention to an alternating current.
Gas-fired morocco fired steam boiler abnormal situation, how should we deal with it? When we use gas steam boiler, failure or abnormal phenomena it is inevitable, but in order not to affect the normal use, in the event of a problem gas steam boiler to be timely processing solutions, then the face of all kinds of circumstances, we should how to handle it? Share some of the ways we deal with unusual circumstances. If only gas steam boiler circulating pump abnormalities, such as its current decreases, the pump outlet pressure back to zero, which indicates no oil pump is idle, it may be caused by oil vaporization. Yang identify the reasons therefore first vaporized measures; such as clogging of the filter circulating pump bypass opening evacuated immediately clean the filter; heat transfer fluid as a result of added aqueous or decomposed gases are not excluded in the system, should immediately open the vent an exhaust valve. Circulation pump pressure constant, the current increases and the flow drops, deterioration of the thermally conductive fluid, the viscosity increased, should be replaced or regenerated. New heat transfer fluid as a result of decomposition of aqueous or excluded gases in the system, should immediately open the vent valve of the exhaust gas. When the current is lower than normal circulation pump, the circulation pump efficiency is decreased, the flow rate decline may be heating pipes plug fouling, stainless steel chain should be cleaned. If the gas steam boiler before and after the filter increased in pressure, the pump inlet pressure drops, the filter may be stuck, the opening of the bypass, disassemble and clean the filter. In addition to its low furnace outlet temperature liquid phase heat carrier, mainly for lack of heat fouling problems, it is timely soot blowing. Gas steam boiler grate more common problem is stuck, there are reasons including breaking grate or the grate off loose pins; coal grate has stuck to metallic inclusions; arched grate; slag is sinking the tip of the grate stuck. In response to this phenomenon, the required reverse hand grate plate debris removal, replacement breaking grate after the start, then jammed as startup, stop the rotation of the reasons detailed inspection to resolve. But also to re-adjust the adjustment screw on both sides of the grate tension, if still does not work, we need to replace the sprocket.
Why boiler furnace exhaust gas temperature increases heat losses the heat loss is largest in a boiler, furnace 6% is generally fed to the heat, the exhaust gas temperature increasing every 12 ~ 15 ℃, heat losses to an increase of 0.5%. Therefore, the exhaust gas temperature is one of the most important indicators boiler operation. Here are a few reasons may cause the furnace exhaust gas temperature rise: (1) heating surface slagging, fouling. Whether waterwall slagging furnace fouling, or superheater, convection bank, and economizer preheater fouling are due to increased resistance measured smoke, heat deterioration of the cooling effect deteriorates the flue gas, resulting in increased exhaust gas temperature. (2) the excess air ratio is too large. Under normal circumstances, the furnace outlet increases as the excess air ratio of the exhaust gas temperature rises. After the excess air ratio increases, while the amount of smoke increases, the speed increase of smoke, heat strengthening of exiled, but less than the degree of increase in heat transfer gas volume increases more. It will be appreciated as the tobacco rate increased, the time to heat to the flue gas working fluid left the heating surface. (3) leakage factor is too large. Tail shaft furnace and boiler flue negative pressure leakage is inevitable, and provides a heating surface allowed leakage coefficient. When the coefficient of air leakage increases, the influence of the exhaust gas temperature and overfire air coefficient increases similarly. And the closer the leakage furnace, exhaust gas temperature raising effect on the greater. (4) water temperature. When the turbine load is low or high pressure splitting when the heater temperature of the boiler feedwater will decrease. Generally, when the water temperature rises, if the amount of fuel is maintained constant, the temperature difference decreases economizer, economizer heat absorption decreases the exhaust gas temperature rises. (5) the fuel moisture. The fuel in the flue gas to increase the amount of water increases, and therefore the exhaust gas temperature rises. (6) boiler load. Although the boiler load increases, the amount of smoke, the amount of steam to the water, the air amount increases in proportion, but since the furnace exit gas temperature is increased, so that the exhaust gas temperature rises. After the load is increased to increase the furnace outlet temperature, followed by convection heating surface temperature difference increases, an increase in heat absorption, the more so the convection heating surface, the smaller the impact load change of a boiler exhaust gas temperature. (7) The fuel species. When burning low calorific value gas, since the furnace temperature is lowered to reduce the radiation heat transfer in the furnace, the low calorific value gas in a non-combustible components, mainly N2, CO2, H2O more, the amount of flue gas increases, the exhaust gas temperature rise high. Pulverized after burning oil, although oil-fired furnace outlet when the excess air ratio than the coal is low, but the little ash fuel oil, and no larger soot particles, larger ash particles in the flue gas absent the cleaning action of surface heating, convection heating surface more polluting. So bad combustion, often black smoke boiler flue gas temperature. When the tail has means ash ball, since the tail cleaner, the exhaust gas temperature is slightly lower than the burning coal. (8) milling system operation. Bunker has a reservoir of closed milling system is concerned, when the pulverizing system is running, because a portion of the water in the fuel into the furnace, the furnace temperature is reduced and the amount of smoke increases, the leakage into the pulverizing system is running as the primary cold air air into the furnace, to reduce the amount of air flowing through the air preheater to the exhaust gas temperature rises. Conversely, when the exhaust gas temperature is reduced pulverizing system outage.
