DHL series of coal fired single drum grate hot water boiler

A) DHL series of coal fired single drum grate hot water boiler

The drum of DHL series corner tube hot water boiler is laid in the external, and all around the furnace and rear flue, there’s totally-enclosed membrane water cooled wall, which makes the boiler well sealed with high thermal efficiency. The fin grate which is driven by infinitive variable gear box is newly designed with high casting precision, so there’s a low loss of mechanical incomplete combustion.
