Fire fighting methods inventory 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.

Our horizontal CFB coal fired steam boiler epc high quality for sale has various types: coal fired CFB steam boiler, biomass fired CFB steam boiler. This basic mode of operation is found in most every steam boiler, but there are a few modifications that have been created for different purposes. A superheated boiler takes the standard process and further heats the steam, increasing the temperature and energy output, and it commonly is used to rotate large turbines. Water tube boilers replace the large tank with a series of water-filled tubes that can reach boiling faster and give off more steam.

The reason gas coal fired steam boiler epc high quality flame of abnormal phenomena and processing method. Flameout for the following reasons: 1. Auxiliary trip or power interruption. 2. boiler combustion instability. 3. When the load is too low, due to the sudden drop in load, ignition energy mill will be lost or the combustion is automatically stopped. 4. mutation coal, low volatile or low calorific value. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. 5, the automatic combustion flame detectors or failure resulting in failure to trip mill. 6. The furnace wall or squib serious improper boiler soot-blowing operation, a large amount of steam into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a substantial amount of fuel reduction or interruption. A large amount of water or impurities in the fuel oil gun clogging, or atomized vapor pressure is too low. Second, the phenomenon: 1, furnace pressure was significantly higher, flameless furnace flame monitoring CRT display. Pit of fire no fire. BTG MFT alarm window alarm indicator lights. 2. The unit load is reduced, steam flow drops rapidly, and the temperature of each section of the working medium vapor pressure decrease, a sharp increase in oxygen index. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. 3. Treatment: 1. If you refuse to run MFT protection, emergency stop should be handled according to the situation and stop the supply of fuel. 2.2. Identify the cause of stalling, and try to eliminate it. Conduct a comprehensive inspection of the boiler, and to confirm proper before the device is restarted.
