Type JRF series coal-fired hot blast stove

Working principle
The furnace integrates combustion and heat exchange. The new indirect heating technology uses high temperature parts of the furnace body to exchange heat. 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 to use, and low price.
Performance characteristics
  Adopt high temperature resistance measures, so that its service life is much longer than that of tube-type hot blast stove, and adopt the flue gas longitudinal washing fins and negative pressure smoke exhaust method, the heat exchange part does not accumulate dust, does not need to be cleaned, and the thermal performance is stable. Various 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, etc.
Technical specifications

Attention
◎Environmental reference temperature standard is 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 JRF4 type hot blast stove can reach above 200℃, and the temperature of JRF5 JRF6 type can reach above 300℃ (for special manufacturing, it can reach above 500℃), and users can adjust it according to their needs.
◎The height of the smoke window of the hot blast stove: 3 to 5 meters for JRF4 type, 5 to 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.
