Modern hot-gas generator furnaces operating on solid fuel.

The article describes hot-gas generator furnaces operating on coal and used in drying processes. Under analysis are special features of vertical furnaces working on pulverised coal and furnaces that burn raw lump coal on a moving grate. The basic technical-and-economic indicators of various furnaces are compared in order to assess the expediency of converting them firm gaseous to coal fuel.
