Food is food industry is human life industry, but also an ancient and eternal evergreen industry. Industrial pressure vessel code steam boiler as an integral part of the chain, is mainly used for processing of distillation, extraction, sterilizing, drying, curing and other processes. Anqing City, Anhui Province is located in the Want Want Foods Co., Ltd. mainly engaged in all kinds of puffed food processing and manufacturing and sale of steam boiler steam delivered directly or indirectly in contact with food, thus requiring the steam quality is very high. Due to expanding production needs, Want Want Foods in urgent need of a boiler plant to provide high-quality steam. After a comprehensive understanding of the boiler industry, determined to cooperate with the fast boiler. Want fast square perennial cooperation with the country's food company, it has considerable experience of cooperation. By understanding the needs of the Want Want food production, providing a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
Why do you want to be purged before boiler ignition and its tail pressure Description: knowledge and mastery learning boiler regard, the following will be continued, because this work is not yet complete, it can not be stopped. So, based on this, and so we have some gains and progress, without further ado, to immediately proceed with it, hoping to achieve the above purpose. Related workers 1. boiler water quality testing, and whether special operations personnel? And, on the boiler steam box, why should a fire be arranged exhaust pipes? For a question, the answer is yes, that is, the relevant operator of the boiler water quality testing, and is part of special operations personnel, or that belong to special equipment operator. In the boiler, which is arranged on the object of fire steam manifold exhaust duct, there are mainly two, one is for discharging air in the boiler starts to play the second is a safety valve for overpressure protection, and exhaust steam.
In operation, the boiler exhaust gas temperature rise because the heat loss due to heat loss is the largest in a boiler, typically around 6% into the furnace heat, the exhaust gas temperature increasing every 12 ~ 15 ℃, smoke 0.5% increase in heat loss. Therefore, the exhaust gas temperature is one of the most important indicators of boiler operation, must be the focus of monitoring. Several factors has the potential to increase the exhaust gas temperature of the boiler: (1) heating surface slagging, fouling. Whether waterwall slagging furnace fouling, or superheater, convection bank, and economizer preheater heat resistance due to fouling will increase the flue gas side, heat deterioration of the cooling effect of the flue gas becomes difference, resulting in increased exhaust gas temperature. (2) the excess air ratio is too large. Under normal circumstances, the furnace outlet increases as the excess air ratio of the exhaust gas temperature rises. After the excess air ratio increases, while the amount of smoke increases, the speed increase of smoke, heat strengthening of exiled, but less than the degree of increase in heat transfer gas volume increases more. It will be appreciated as the tobacco rate increased, the time to heat to the flue gas working fluid left the heating surface. (3) leakage factor is too large. Tail shaft furnace and boiler flue negative pressure leakage is inevitable, and provides a heating surface allowed leakage coefficient. When the coefficient of air leakage increases, the influence of the exhaust gas temperature is increased and the excess air coefficient is similar. And the closer the leakage furnace, exhaust gas temperature raising effect on the greater. (4) water temperature. When the turbine load is low or high pressure splitting when the heater temperature of the boiler feedwater will decrease. Generally, when the water temperature rises, if the amount of fuel is maintained constant, the temperature difference decreases economizer, economizer heat absorption decreases the exhaust gas temperature rises. (5) the fuel moisture. The fuel in the flue gas to increase the amount of water increases, and therefore the exhaust gas temperature rises. (6) boiler load. Although the boiler load increases, the amount of smoke, the amount of steam to the water, the air amount increases in proportion, but since the furnace exit gas temperature is increased, so that the exhaust gas temperature rises. After the load is increased to increase the furnace outlet temperature, followed by convection heating surface temperature difference increases, an increase in heat absorption, the more so the convection heating surface, the smaller the impact load change of a boiler exhaust gas temperature. (7) The fuel species. When burning low calorific value gas, since the furnace temperature is lowered to reduce the radiation heat transfer in the furnace, the low calorific value gas in a non-combustible components, mainly N2, CO2, H2O more, the amount of flue gas increases, the exhaust gas temperature rise high.
