DHL Coal Boiler Features

1. Corner Tube Structure

The main frame consists of four corner tubes serving as both load-bearing and downcomer pipes.

The whole boiler body forms a self-supporting structure, requiring no steel frame for installation — easy to assemble on site.

2. Single Drum & Natural Circulation

Steam-water separation occurs in a single drum, simplifying the system and improving reliability.

The circulation is natural, ensuring safe and stable operation even under variable load conditions.

3. Membrane Water Wall

The combustion chamber is surrounded by welded membrane water walls, providing excellent gas-tightness and efficient heat transfer.

Effectively reduces heat loss and improves boiler thermal efficiency.

4. High-Efficiency Furnace Design

Equipped with a large furnace volume and optimized air distribution system.

Ensures complete combustion of bituminous coal, lignite, or biomass fuel (if adapted).

5. Low emission of smoke and dust.

Economizer and Air Preheater

Fitted with a tail-end economizer and air preheater to recover waste heat.

Increases boiler efficiency up to 82–85%, reducing coal consumption.
