working principle
The furnace integrates combustion and heat exchange and uses high-temperature parts of the furnace body to conduct heat exchange. Smoke and air flow independently. Heating is environmentally friendly, with high thermal efficiency (up to 60-75%), rapid temperature rise, small size, easy to install, reliable to use, and low price.
performance characteristics
High-temperature resistance measures have been adopted to greatly extend its life compared with tubular hot blast stoves. The flue gas longitudinal flushing fins and negative pressure smoke exhaust methods have been adopted. No dust accumulates in the heat exchange parts, no cleaning is needed, and the thermal performance is stable. Various coal or firewood can be used as fuel and is equipped with a secondary air inlet device to burn completely. All technical and economic indicators of the furnace have reached the domestic ^level.
Adapt materials
This furnace is a universal hot air device and is used in conjunction with drying equipment for various materials. It is widely used for heating and dehumidifying grain, seeds, feed, fruits, dehydrated vegetables, fragrant shavings, fungus, tremella, tea, tobacco and other agricultural products, food, pharmaceuticals, chemical raw materials, light and heavy industrial products. It can also be used for heating of various facilities and dehumidifying warehouses.

Attention
◎ The environmental benchmark temperature standard is 18℃±2℃, and the calorific value of coal is calculated as 5000Kcal/kg.
◎ The hot air temperature in the table is determined based on the output air volume. The hot air temperature ^of the hot air stove JRF4 can reach more than 200℃, and the hot air temperature ^of the JRF5 JRF6 can reach more than 300 ℃ (specially manufactured can reach more than 500 ℃). Users can adjust it according to needs.
◎ The height of the smoke window of the hot blast stove: 3~5 meters for JRF4 models, and 5~8 meters for JRF and JRF6 models.
◎ See the installation schematic diagram of the hot blast stove for the corresponding positions of the outline size in the table.
◎ The refractory layer on the inner wall of the lower part of the furnace starts from the grate, and its height is 0.5 meters for JRF4 - 4 type, which can be installed on site.
◎ Model JRF6 is a chain grate type combustion device.
