The problems existing in Fangkuai how to calculate the boiler efficiency coal-fired coal are: 1, coal ash is more than 2, coal particles are uneven, 3, coal contains a large number of impurities, 4, coal calorific value is low, 5, combustion is not easy to ignite fire, 6, The moisture content in coal is uncertain. 7, coal is not easy to burn, slag carbon content is high. In general, it is best to use the designed coal or coal close to the designed coal to ensure stable combustion. In recent years, due to the increasing shortage of coal supply around the country and the diversification of coal supply, the quality of coal is much different from that of the previous coal types, and the stable combustion and normal combustion of boilers have been carried out. The operation of heating has a great impact. The influence of coal quality on boiler stable combustion: the heat generation of coal is an important index to reflect the quality of coal. When the heat generation of coal is low to a certain value, it will not only affect the combustion instability and completeness, but also cause the boiler to extinguish fire. The boiler outlet temperature is very difficult to reach the standard, affecting the normal operation. Volatile matter can be precipitated and burned at lower temperature. With the heat release of combustion, the temperature of coke particles increases rapidly, which provides extremely favorable conditions for ignition and combustion of coke particles. In addition, the release of volatiles increases the internal gap and external reaction area of coke, which is beneficial to increase the combustion rate of coke. Therefore, volatilization The larger the content of components is, the less the fixed carbon content in coal is, the more easy to burn pulverized coal, the more voids obtained from volatilization analysis, the larger the reaction surface area, and the faster the combustion reaction is. When the volatile content is reduced, the ignition temperature of pulverized coal airflow increases significantly, the ignition heat increases, the ignition time becomes longer, the combustion stability decreases, the center of the flame moves up, and the heat absorbed by the radiative surface of the furnace decreases, and the ignition time becomes longer, the combustion stability decreases, the flame center moves up, and the heat absorbed by the furnace radiating surface decreases. The heat absorbed by convection heating surface increases, the exhaust temperature increases and the exhaust loss increases.
