Product Overview:

The GRF series coal-fired high-temperature hot blast stove uses coal, the most common energy source, as the heating medium to generate high-temperature hot air. It is a new type of high-temperature heat source equipment that is environmentally friendly, efficient, and energy-saving in China. All adopt mechanical chain grate coal-fired devices, and the heat exchange device can use high-temperature plate, tube, heat pipe and other heat exchangers. It has the advantages of high output temperature, high calorific value, and high thermal efficiency, and can prepare clean hot air at 100-450 ℃. The technical indicators of the equipment have reached the advanced level in China. Widely used in industries such as chemical, grain, mineral products, food, and building materials. It can be used as an ideal heat source for heating, drying, baking, and heat setting, and can be used in conjunction with various drying equipment.

working principle:

The GRF series coal-fired high-temperature hot blast stove mainly consists of a heating device, a heat exchange device, a dust collector, and a fan. The high-temperature flue gas generated by combustion in the combustion furnace is converted into low-temperature flue gas and discharged after heat exchange with the heat exchanger and preheater. The cold air is then exchanged with the flue gas through the preheater, heat exchanger, and flue gas to produce the required high-temperature clean hot air.
