JRL coal-fired hot blast stove

JRL燃煤热风炉

Working principle
This furnace integrates combustion and heat exchange through indirect heating technology at the high-temperature part of the furnace body. Smoke and air flow separately, heating is absolutely pollution-free, with high thermal efficiency (up to 60-75%), fast heating, small size, easy installation, reliable use, and low price (compared to a one ton boiler, this heating system is only half the price of a boiler heating system).
Performance characteristics
High temperature resistance measures have been taken, greatly extending its lifespan compared to tube type hot air stoves. Longitudinal flushing of heat dissipation fins by flue gas and negative pressure exhaust methods have been adopted, ensuring that the heat exchange area does not accumulate dust and does not require cleaning, resulting in stable thermal performance. Various types of coal or wood can be used as fuel, and equipped with a secondary air inlet device for complete combustion. All technical and economic indicators of the furnace have reached the leading level in China.
Adapt to materials
This furnace is a universal hot air device that is used in conjunction with drying equipment for various materials. Widely used for heating and dehumidification of agricultural products such as grains, seeds, feed, fruits, dehydrated vegetables, fragrant mushrooms, fungus, Tremella fuciformis, tea, tobacco leaves, food, pharmaceuticals, chemical raw materials, and light and heavy industrial products. It can also be used for heating various facilities and dehumidification in warehouses.

Warning Attention
The environmental benchmark temperature standard is 18 ℃± 2 ℃, and the calorific value of coal is calculated at 5000Kcal/kg.
The hot air temperature in the table is determined based on the output air volume. The hot air temperature of JRF4 type hot air stove can reach over 200 ℃, and JRF5 JRF6 type hot air temperature can reach over 300 ℃ (special manufacturing can reach over 500 ℃). Users can adjust it according to their needs.
The height of the smoke window configuration for the hot blast stove is 3-5 meters for JRF4 type, and 5-8 meters for JRF and JRF6 types.
The corresponding positions of the external dimensions in the table are shown in the installation diagram of the hot air stove.
The refractory layer on the inner wall of the lower part of the furnace starts from the grate and has a height of 0.5 meters for JRF4 type, which can be installed on site.
JRF6 type is a chain grate combustion device.
