Fire fighting methods inventory automatic boiler in the boiler use, if a fire phenomenon, you know how to deal with it? Today, Xiao Bian teach you the recipe. When coal is poor or low load, it may be administered less number, to maintain a high pulverized coal concentration, but can not chipping operation or asymmetric operation. Load is less than 170MW, should remain A, B powder layer to stable operation, when any failure to a powder, should be administered stable combustion, the failure to the powder to be put into operation, combustion stability, and then exit the gun run . Adjustment of the amount of the low-load air supply, to maintain the oxygen 4-5%, and adjust the opening degree of the auxiliary windshield. If it is a bad case of fire, may be appropriate to increase the primary air temperature, wind speed reduces time, but not overshoot the spark plugs burned once or blocked ducts. When the job should be strictly periodic system and to reduce powder powder switching system, dust bunker normal position at least 2.5 meters, so that a stable working state bunker, at each adjusting shutter powder to powder, the powder as far as possible amount consistent and stable, no spark plugs to prevent dust and to dust gravity caused by combustion fluctuations. Should maintain acceptable fineness of pulverized coal, according to chemical analysis, after adjusting the test plate to open Classifier, coal is poor or low load, it may be appropriate to increase the fineness of pulverized coal, in order to facilitate combustion. Maintain normal milling system, powder separator shall not clogging the tertiary air pinkish large deterioration in combustion. Furnace can eliminate air leakage and air leakage milling system, all view of the fire without plugging holes, play Giocondo, etc. should be tightly closed. Value of the long should keep abreast of the situation of coal and coal quality fuel, combustion instability occurs when, such as when a fault powder, coal mutation, the differential signal changes drum is too large, the oil should immediately cast coal combustion stability and taking samples for analysis. High load, the premise of ensuring steam temperature, combustion can be appropriately adjusted to prevent the shift of the center of the flame, so that the furnace exit gas temperature rise, caused by coking. Operator adjusting the main steam temperature may be employed with positive pagoda wind run, the central flame stabilizer. Should be a bellows pressure control as a basis for wind speed, in time to observe the duct pressure and temperature, the premise of ensuring primary air duct is not blocked, a bellows pressure should not exceed 4000Pa.
Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type automatic boiler paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.
How fuel (gas) automatic boiler stack height standards should be implemented as specified?According to requirements "Boiler Air Pollutants Emission Standard" -GB13271-2014 existing files countries, oil, gas boiler chimney of not less than 8 meters, the height of the boiler chimney by specific approval of environmental impact assessment documents OK. When there is a building within a radius of 200m from the new boiler room around the chimney, the chimney should be higher than the tallest building in more than 3m.
Steam automatic boiler furnace operating point first launched circulating pump equipment circulating pump outlet, into the furnace, the pressure released, and the system back to the oil pressure, make sure that in the positive practice mode. Circulation pump run for 30 minutes, after the stable operation of the system before it can enter the next step. Open gas pipeline manual valve steam boiler, burner launch button, natural gas burner into the furnace, and then burned, keeping the flame stable condition, is in the safe operation of the equipment. Incineration steam boiler, once the accident shut down if the phenomenon occurs, the device will take the initiative burner interlock protection status, should be promptly cut off natural gas pipeline, launched a purge function of the furnace, the furnace inside air replaced more than clean shutdown. System according to load requirements, temperature requirements and thermal oil outlet, the burner can be actively adjust the size of the amount of fire. Steam boiler heat exchanger is generally divided into two, one is directly touch the touch exchanger, and the other is the direct heat exchanger, which are separate apparatus for flue gas waste heat recovery, energy saving effect complete . Generally steam boiler practices can be simple progress through the transformation of energy-saving action, such as increasing the waste heat recovery equipment installed on, which is energy-saving advantages of steam boilers. Energy savings from the big side, is to promote the cause of saving the country, to say that small ways to create more profits for the company to save costs, the choice of one of the heat exchanger is a good way to complete energy policy.Free Chat
