Overview

The JRF series hot blast stove integrates combustion and heat exchange into an indirect heating technology that exchanges heat at the high-temperature parts of the furnace body. Smoke and air flow separately, heating is 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).

Product Details

JRF series hot blast stove

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 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).

Product Features:

High temperature resistance measures have been taken to extend its lifespan in a tubular mannerhot blast stoveGreatly extended and equipped with smoke longitudinal flushing heat dissipation fins and negative pressure exhaust method, the heat exchange area does not accumulate dust, does not need to be cleaned, and has stable thermal performance. Various types of coal or wood can be used as fuel and equipped with a secondary air intake device for combustion. All technical and economic indicators of the furnace have reached the domestic level.

Application scope:

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.

Note: >The environmental benchmark temperature standard is 18 ℃. The calorific value of coal is calculated at 5500kcal/kg. >The hot air temperature in the table is determined based on the output air volume. The hot air temperature of JRF4 type can reach over 200 degrees Celsius, while JRF5 and JRF6 types >The hot air temperature can reach up to 300 degrees Celsius (or 500 degrees Celsius for special manufacturing). Users can adjust it according to their needs. >The height of the smoke window configuration is 3-5 meters for JRF4 type, and 5-8 meters for JRF5 and JRF6 types. >The corresponding positions of the external dimensions in the table are shown in the installation diagram. >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 JRF4-4 type, which can be installed on site. >JRF6 type is a chain grate combustion device.
