Hot sale portable coal fired blast furnace Summary of coal fired hot air furnace:        Direct-fired hot-blast stove is made up of combustion chamber, settling chamber and mixing air chamber. Fuel is put into the combustion chamber manually. Under the effect of air blower, the fuel burns fiercely and produces high-temperature smoke with dust, which enters into the settling chamber to remove dust. Certain amount of cold air can mix with the hot air from the clean room, so hot smoke of different temperature can be offered. It can offer heat source for various kinds of drying systems.     Summary of  coal fired hot air furnaces          The series of HLF type vertical hot-blast stove are high-efficience and energy-saving products developed by our corporation. Matched with special drying device, this hot-blast stove applies to dewatering of grain, food, fodder, fruits and vegetables and Other industries which need hot-blast.   Structural principle of  coal fired hot air furnaces           The hot-blast stove collect combustion and heat transfer as a whole. Either smoke or air has its own way. The hearth itself has heat transfer effect. Smoke flue and air flue are crossed and strictly insulated. Under the effect of draft fan, smoke and cold air rotate and flow reversely, and become pure hot blast through heat sink. Then the hot blast is sent to the dryer by hot-air blower.   Process view of  coal fired hot air furnaces     Characteristics of  coal fired hot air furnaces: 1.Use ordinary industrial coal, firewood and rice husk as its fuel, air as the heat-transfer medium. It has high efficiency and is energy saving, safe and reliable.   2.The hot-blast stove itself has dedusting function, so another dedusting equipment is saved, which meets the environmental protection requirement.   3.The temperature range of outlet hot blast is large; the warming speed is rapid; the blast capacity is adjustable; it is easy to install and meets different technology requirements.   4.Good heat-transfer effect and high heat energy use ratio.   5.Smoke flue and hot-blast flue are strictly insulated from each other, so hot-blast drying won’t pollute the material.
