Boiler excess air ratio increases, why steam temperature rises to follow? Excess air ratio increases boiler (originally assumed optimum excess air ratio), the temperature drop in the furnace, the heat radiation wall absorption reduction, the furnace exit gas temperature decreased slightly. Since the magnitude of the amount of smoke increases, the speed increase of smoke, the heat transfer coefficient of heat transfer temperature difference is greater than the rate of increase is reduced, so that the increase in heat absorption of the superheater. Since the increase in the amount of exhaust gas temperature and flue gas, q2 is increased, reducing the efficiency of the boiler, in the case where the same amount of fuel. Reducing evaporation, and therefore, the steam temperature rise. Generally, the excess air coefficient of 0.1 for each increase, steam temperature rise 8 ~ 1O ℃.
Food Factory drum boiler water wall and its prevention package of food plant boiler water wall bulge causes and preventive measures? When the water wall tube localized corrosion occurs, the inner wall becomes rough, scaly easily formed in a relatively rough places, and then thickens. Local no good expanded metal soda mixture was cooled temperature, creep speed, and the tubes are not contaminated due to obtain good low-temperature cooling wall, creep does not occur. Water wall tube macro scale for local expansion properties. If you cut the pipe, it was discovered where the drum, the inner wall have been contaminated. Food plant boiler drum wall 1. Summary of the cooling water supply common cause unacceptable quality, contamination of impurities into the boiler heating surface. 2. Run the improper operation of the tube wall overtemperature. 3. flames sweep wall, resulting in long-term water wall tube overheating. The high temperature of the water wall, which makes the metal surface of the water wall had a great temperature gradient. If insufficient cooling capacity of the pipeline medium, the direct result of the water wall temperature is too high.
The boiler thermal power is more than 90%. The combination of bellows and conical stoves with outstanding expansion function is selected. The scale of the tank coincides with the flame, and the flow area of the flue gas is reduced so as to make the flue gas move at constant speed. Ensure the heat transfer time of the high temperature flue gas in the furnace to reach the best heat transfer function;
