一、“V”型布风板流化床锅炉发展概况煤在“V”型布风板流化床中燃烧具有较高的燃烧强度,沉浸在流化床中受热面吸取的热量约占总热量的40～50％,这两个要素兼备为提高流化床锅炉紧凑性提供了可能。因而燃烧效率高,锅炉结构紧凑、体积小,燃料适应性广,灰渣可以综合利用。还可利用低温燃烧的特点来降低烟气中NO_x和SO_2的排放量,以减少环境污染,具有常规的燃煤锅炉不可比拟的独特优点。
First, the “V” -shaped fluidized bed boiler development overview Coal in the “V” -shaped fluidized bed fluidized bed combustion has a high degree of combustion, heat immersed in the fluidized bed heating surface accounts for about the total The heat of 40 to 50%, both of these elements to improve the compactness of the fluidized bed boiler provides the possibility. Therefore, high combustion efficiency, the boiler structure is compact, small size, wide adaptability of fuel, ash can be comprehensive utilization. The characteristics of low temperature combustion can also be utilized to reduce NO x and SO 2 emissions in the flue gas so as to reduce environmental pollution and have the unique advantages of conventional coal-fired boilers.
