JRF Series Coal-fired Hot Air Furnace



Overview: This furnace is a universal hot air device, used in conjunction with drying equipment for various materials. It is widely used for heating and dehumidifying agricultural products, food, pharmaceuticals, chemical raw materials, and light and heavy industrial products such as grain, seeds, feed, fruits, dehydrated vegetables, shiitake mushrooms, wood ear mushrooms, white fungus, tea, tobacco leaves, etc. It can also be used for heating various facilities and dehumidifying warehouses.







Brief Description: The furnace is a universal hot air device, used in conjunction with drying equipment for various materials.

Category: Heat Source Equipment Series

Application:

    This furnace is a universal hot air device, used in conjunction with drying equipment for various materials. It is widely used for heating and dehumidifying agricultural products, food, pharmaceuticals, chemical raw materials, and light and heavy industrial products such as grain, seeds, feed, fruits, dehydrated vegetables, shiitake mushrooms, wood ear mushrooms, white fungus, tea, tobacco leaves, etc. It can also be used for heating various facilities and dehumidifying warehouses.

Principle:

    This furnace integrates combustion and heat exchange, using the latest indirect heating technology that exchanges heat at the high-temperature part of the furnace body. Smoke and air each have their own paths, ensuring absolutely pollution-free heating. The thermal efficiency is as high as (60-75%), with fast heating, small size, easy installation, reliable operation, and low price (compared to a one-ton boiler, this heating system costs only half the price of a boiler heating system).

Features:

    High-temperature resistant measures are adopted, greatly extending its service life compared to tubular hot air furnaces. It uses longitudinal flue gas scouring of heat sinks and negative pressure exhaust, so the heat exchange parts do not accumulate dust and require no cleaning, ensuring stable thermal performance. It can use various types of coal or wood as fuel, and is equipped with a secondary air intake device for complete combustion. All technical aspects of this furnace have reached the domestic leading level.
