Working Principle

The furnace combustion and heat transfer as a whole to the high-temperature parts of the furnace body for heat transfer of indirect heating technology, smoke and air in their own way, heating absolutely no pollution, high thermal efficiency (up to 60-75%), fast heating, small size, easy to install, reliable, and low price (compared with a ton of boiler heating system is only equivalent to the boiler heating system half of the price).

Equipment features

Adopted high temperature resistance measures, so that its life than the tube-type hot air furnace greatly extended, and the use of flue gas longitudinal scouring of the heat sink and negative pressure type smoke exhaust, heat transfer parts do not accumulate dust, no need to clean up, stable thermal performance. Various kinds of coal or firewood can be used as fuel, and is equipped with a second air intake device to burn completely. The furnace's technical and economic indicators have reached the domestic level.

Scope of application
