working principle
The furnace integrates combustion and heat exchange, a new type of indirect heating technology that exchanges heat at high temperature parts of the furnace body. Smoke and air go in different ways. The heating is environmentally friendly, with high thermal efficiency (up to 60-75%), fast heating, small size, and installation Convenient, reliable, and low price.
Performance characteristics
Adopting high temperature resistance measures, so that its life is greatly extended than that of tubular hot blast stoves, and adopting vertical flue gas scouring fins and negative pressure smoke exhaust method, the heat exchange part does not accumulate dust, does not need to be cleaned, and has stable thermal performance. All kinds of coal or firewood can be used as fuel, and it is equipped with a secondary air inlet device to burn completely.
Adapt to materials
The furnace is a universal hot air device, which is used in conjunction with drying equipment for various materials. It is widely used for heating and dehumidifying food, seeds, feed, fruits, dehydrated vegetables, fragrant rudder, fungus, white fungus, tea, tobacco and other agricultural products, food, pharmaceuticals, chemical raw materials, and light and heavy industrial products. It can also be used for heating in various facilities As well as dehumidification of the warehouse.

Attention
◎Environmental reference temperature standard is at 18℃±2℃, and the calorific value of coal is calculated at 5000Kcal/k g.
◎The hot air temperature in the table is determined according to the output air volume. The hot air temperature of the hot blast stove JRF4 can reach 200℃ or higher, and the JRF5 JRF6 hot air temperature can reach 300℃ (for special manufacturing up to 500℃), users can adjust it according to their needs.
◎The height of the smoke window of the hot blast stove: 3～5 meters for JRF4 type, 5～8 meters for JRF and JRF6 type.
◎The corresponding positions of the outline dimensions in the table are shown in the installation diagram of the hot blast stove.
◎The refractory layer on the inner side wall of the lower part of the furnace starts from the grate, and its height: JRF4- 4 is 0.5 meters, which can be installed on site.
◎JRF6 type is a chain grate type combustion device.
