Biomass fired circulating fluidized bed boiler technology
Food is food industry is human life industry, but also an ancient and eternal evergreen industry. Industrial steam atmospheric pressure boiler 10t agent 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).
Boiler selection is too small, resulting in less heat heating system, boiler water temperature is maintained at a low temperature level, there will be a lot of condensed water; of course, the boiler oversized, long-term can not run at the rated thermal load, nor conducive to the boiler operation and maintenance.
Why ash rear of the atmospheric pressure boiler 10t agent heating surface steam temperature will reduce? In order to clean the boiler heating surface, reducing the exhaust gas temperature to raise the thermal efficiency of the boiler, heating surface, convection heating surface is mainly ash regularly. Since thermal efficiency boilers, such as maintaining the same boiler evaporation, the amount of fuel supplied into the furnace, the flue gas temperature and smoke velocity reduction furnace outlet, the heat absorption of the superheater heat transfer coefficient due to the temperature difference and the heat of the gas side lowering reduced, resulting in superheated steam temperature drops. The fuel quantity remains unchanged, the furnace exit gas temperature and smoke constant speed, due to increased steam flow and reduce heat absorption per unit mass of steam, superheater outlet steam temperature drops. Thus, convection heating surface ash, whether it is to maintain unchanged the amount of evaporation or the amount of fuel remains unchanged, so that both steam temperature drops.
