燃煤沸腾床锅炉,不同于一般燃煤锅炉,进入沸腾床的空气量既要满足煤的燃烧要求,又要满足使床料(灰渣和煤的混合物)获得良好沸腾状态的要求。建立沸腾床的必要与充分条件,并不是燃煤沸腾床锅炉的合理沸腾工况的范围值。
Unlike the normal coal-fired boilers, the amount of air entering the ebullated bed meets both the combustion requirements of coal and the need to achieve good boiling of the bed material (mixture of ash and coal). Necessary and sufficient conditions for establishing an ebullated bed are not values for a reasonable boiling regime for a bubbling bed boiler.
