◆The furnace integrates combustion and heat exchange as the latest indirect heating technology for heat exchange at the high temperature part of the furnace body. Smoke and air travel in their own ways. The heating is absolutely pollution-free, the thermal efficiency is high (up to 60~75%), the temperature rises quickly, and the volume Small, easy to install and reliable to use. High temperature resistance measures have been taken to greatly extend the service life of the tube type hot blast stove, and the flue gas is used to longitudinally wash the fins and the negative pressure smoke exhaust method. The heat exchange part does not accumulate dust, no need to clean up, and the thermal performance is stable. All kinds of coal or firewood can be used as fuel, and a secondary air intake device is used to burn completely. The technical and economic indicators of the top of the furnace have reached the domestic leading level.

Warning Note:
◆Environmental reference temperature standard is 18℃±2℃, and the calorific value of coal is calculated at 5000kcal/kg.
◆The hot air temperature in the table is determined according to the output air volume. The hot air temperature of the hot air furnace JRF4 type can reach up to 200 ℃, and the hot air temperature of JRF5 and JRF6 types can reach up to 300 ℃ (special manufacturing can reach more than 500 ℃), and users can adjust it according to their needs.
◆The height of the chimney configuration of hot blast stove: JRF4 type 3 ~ 5 meters, JRF5, JRF6 type 5 ~ 8 meters.
◆See the installation diagram of hot blast stove for the corresponding position of the external dimensions in the table.
◆The refractory layer on the inner side wall of the lower part of the furnace starts from the grate, and its height: JRF4-4 is 0.5 meters, which can be installed on site.
◆JRF6 is a chain grate combustion device.
