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.
Subsequently, the Secretary-General Wang Jiao Ling line with the company's quality control staff had a discussion on the case of the reform of administrative licensing review of the existing boiler model in the country, how to promote the development of high quality assessment boiler, with the assessment of how businesses, trade associations and work promoting industry innovation and innovation to lead the development of what the expectations and demands, boiler regulations and technical specifications and implementation issues recommendations related issues exist in the process conducted in-depth exchanges and discussions, and Lu, president of the company's quality management staff made a lot of valuable Suggest. Wang Jiao Ling Secretary-General spoke highly of the technical aspects of the advantages of fast Boiler green energy and green development, and other fast-outstanding contributions boiler industry group to promote environmental protection and efficient process affirmed.
Factors which influence energy-intensive industrial boiler energy-intensive industrial boilers factors influencing factors which have high energy consumption of industrial boilers which have 1, energy consumption is low management level industrial boiler is too large, are long-term presence of many companies in the current . On the one hand understanding of the enterprise energy conservation boiler is still not sufficient, on the other hand the energy management level is still at a low level, and even some companies even the most basic measuring instruments are not equipped. In order to reduce operating costs, many companies have to buy the old boiler use, lack of components purchased fuel means of inspection. Even in the case of raw coal screening is not performed, it is directly put into production use, it is difficult to ensure full combustion of coal. Not only the thermal efficiency is low, but also resulted in a waste of fuel. 2, heat recovery is poor combustion is incomplete, the situation is the high rate of heat loss is extremely common in industrial boilers used in the process, saving the main parameters of the boiler will be exceeded. Economizer function is to heat energy recovered, but in actual use, heat recovery efficiency is very low. In this case, do not use a lot of boiler economizer direct altogether, inevitably produce exhaust gas temperature is too high. Meanwhile, return the device and steam condensate recovery, it has not been fully appreciated and better use, some are put to use in the boiler after installation, and did not take appropriate measures to deal with poor recycling effect. 3, lack of effective supervision of the level of energy service work, depends largely on the level of experience and technical personnel. But in practical terms, due to the lack of technical personnel, resulting in the energy service work at the level of the low. Various enterprises produced energy-saving products with high imitation, coupled with the lack of effective supervision of energy-saving measures, resulting in the entire market of energy-saving products more confusing. The effect of not only energy-saving effect is not ideal, and to transform the poor, the performance of energy-saving products remains to be greatly improved. Market confusion, vicious competition phenomenon has not been fundamentally curbed.
6 tons adjusting a combustion gas iran 1 ton coal fired steam boiler, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.
