Coal-fired hot air furnace introduction: The coal-fired hot air furnace, also known as an air heater, is a new type of heat exchange equipment that uses coal as fuel and air as the medium. It can continuously provide clean, constant temperature, constant pressure, and dust-free hot air. It is widely used in preventing dyeing and bleaching, rubber coating heat setting; drying of iron printing coatings, metal surface rust removal, and paint curing; papermaking industry drying, grain feed, fish meal, tobacco leaves, tea, compound fertilizer, and other drying processes; forming and drying of particleboard and gypsum board, wood drying, chemical material spray drying, and industrial workshop heating, etc. It replaces the current methods of heating air with steam, thermal oil, or electric heating, reducing the heat exchange stages and corresponding heat exchange equipment. It offers advantages such as high system thermal efficiency, simplified equipment, convenient operation, safety, reliability, and low engineering investment. Coal-fired hot air furnaces can be customized according to customer requirements, such as horizontal chain grate hot air furnaces with high automation, equipped with hopper coal feeders and screw slag discharge machines. For smaller models, fixed grate coal-fired hot air furnaces can also be used.
