TDZRL direct chain grate furnace is a kind of direct hot air furnace takes coal or firewood as fuel, and outputs high temperature hot air.
This type hot air furnace is also called chain furnace. Under the driving force of chain, fuel will be burnt and discharged automatically. It is featured in energy saving. It can use coal, wood, biomass pellets and other similar items as fuel. Hot air will be produced directly by combustion. It mainly contains of combustion furnace, fuel feeder, slag remover, blower, gearbox, purification chamber, blower, duct, gate valve, air distribution door and ash cleaning door.
