Coal stove integrates combustion and heat exchanger together, the heat transfer of the latest technology to indirect heating furnace of high temperature parts, smoke and air separately, heating has no pollution, high thermal efficiency (up to 60-75%), coal stove heating speed, small volume, convenient installation, reliable use, and low price (with a ton of boiler heating system compared to the boiler heating system is only equivalent to half price).
The environmental reference temperature standards by 18 - 2 Deg. C, the calorific value of coal is calculated based on the 5000Kcal/k G.
The hot air temperature in the table is determined according to the air output. The hot air temperature of JRF4 type hot blast stove can be up to more than 200 degrees, and the hot air temperature of JRF5 and JRF6 can reach above 300 DEG C (the special requirement can be more than 500 DEG C). The user needs to adjust according to the need.
The stove chimney height configuration: JRF4 3 ~ 5 meters, JRF, JRF6 for 5 ~ 8 meters.
The dimension table corresponding to the position to see the installation diagram of hot blast furnace.
The refractory layer on the inner wall of the lower part of the furnace grate in place as a starting point, its height: JRF4- type 4 is 0.5 meters, on-site installation.
The JRF6 type chain grate combustion device.
The utility model relates to a coal burning hot blast stove, which is a universal hot air device, and is matched with drying equipment for various materials. Coal fired hot blast furnace is widely used in food, feed, seed, fruit, dehydrated vegetable, mushroom, agaric, tremella, tea, tobacco and other agricultural products, food, pharmaceuticals, chemical raw materials, light industrial products can also be used for various heating and dehumidification, heating and dehumidification facilities warehouse etc..
Coal stove uses the high temperature resistant measures, so that the service life is much longer than the tubular stove, and the smoke longitudinal flow heat sink and negative pressure ventilation, heat exchange part no dust accumulation, no need to clean, stable thermal performance. The coal burning hot blast stove can be made of various coal or firewood as fuel, and is equipped with two air inlet devices, and the combustion is complete. The technical and economic indexes of the coal-fired hot blast stove have reached the leading level in china.
