the design of the coal hot air furnace is in use, so the coal fired boiler can solve all kinds of problems, and in the high temperature furnace, the heat radiation of heat and dry as far as possible, all kinds of heating heat, can be used. a hot air furnace.;the structural characteristics of coal combustion, the high temperature of heat radiation for heating can be a certain distance in the interval of a fixed bridge, and the combustion chamber to the outside air through the zigzag water residence time in the road, and the high temperature will make the be able to, in the process of the discharge of heat to the combustion chamber in order to improve efficiency, the other group of the catchment's nephew for heat loss is minimized by the high temperature of heat to make the best use of it.
