Overview

Features: The JRF series coal-fired hot blast stove adopts high temperature resistance measures, which greatly extends its service life compared to the tubular hot blast stove. It also adopts longitudinal flushing heat dissipation fins for flue gas and negative pressure exhaust method. The heat exchange part 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 inlet device for combustion. The technical and economic indicators of the furnace have reached a certain level.

Product Details

JRF seriescoal-fired hot blast stovePrinciple: This furnace integrates combustion and heat exchange, with heat exchange carried out at the high-temperature parts of the furnace body. Smoke and air flow separately, heating is pollution-free, with a thermal efficiency of up to 60-75%. It heats up quickly, has a small size, is easy to install, is reliable to use, and has a low price (compared to a one ton boiler, this heating system is only half the price of a boiler heating system).

JRF seriescoal-fired hot blast stoveApplication: This furnace is a universal hot air device that is used in conjunction with various drying equipment. Widely applicable for heating and dehumidifying products such as grains, seeds, feed, fruits, dehydrated vegetables, fragrant mushrooms, fungus, tea flavor, tobacco leaves, food, pharmaceuticals, chemical raw materials, and light and heavy industrial products. It can also be used for heating various equipment and dehumidifying warehouses.

Note:

The environmental benchmark temperature standard is 18 ° C ± 2 ° C, and 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 hot air stove can reach up to 200 ° C or above, while the hot air temperature of JRF5 and JRF6 types can reach up to 300 ° C or above (special manufacturing can reach 500 ° C or above). Users can adjust it according to their needs.
The chimney height of the hot blast stove 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 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 JRF4-4 type, which can be installed on site.
JRF6 type is a chain grate combustion device.
