Product Introduction

The DZL type coal-fired horizontal hot water boiler is a horizontal three-pass fire-water tube hybrid boiler with a bundle of threaded smoke tubes arranged inside the drum. Smooth tube water-cooled walls are installed on both sides of the furnace. It adopts a lightweight block chain grate, equipped with a blower and an induced draft fan for mechanical ventilation. Fuel falls into the hopper and onto the grate, where it fully burns in the furnace. The flame then passes through the flue gas channel in the middle furnace wall to the rear of the main body, turns through the burnout chamber on both sides, flows into the front smoke box, and then returns to the boiler tube bundle through the rear smoke box, enters the dust collector, and is finally drawn by the induced draft fan through the flue to the chimney and discharged into the atmosphere.
