DHL/SHL Corner Tube Coal Boiler 

DHL/SHL series coal-fired chain grate water tube boiler, adopts a corner-tube (single-drum or double-drum) structure, in which the water-cooled tubes form the supporting framework of the entire boiler.

Structure: Corner Tube Boiler is a compact and efficient boiler that utilizes a pipe system as its skeleton. With fully enclosed membrane wall structure, flag tube design for the convective heating surface, this non-frame design reduces steel consumption, increases strength, and ensures excellent thermal stability. With advantages of stable operation, convenient maintenance, and strong fuel adaptability.

1. Broad Fuel Compatibility

Compatible with coal, biomass, rice husks, wood chips, corn cobs, sawdust etc.

2. High Combustion Efficiency

Cross-beam chain grate and membrane water-cooled wall ensure thorough fuel combustion

3. High Degree of Intelligence

Advanced control, automated fuel, ash, slag operations

4. Customizable Boiler System

Tailored solutions for feed, slag, and gas treatment, saving time and money

 Boiler Specifications 

1. The four corners of the corner tube hot water boiler are large-diameter thick-walled downcomers, the boiler is consist with downcomers, boiler drum, water-cooled wall, header, flag-shaped heating surface, and reinforcing beam. No steel frame structure.

2. The drum of the angle tube hot water boiler is external longitudinal arranged or a horizontal arranged, the furnace outlet is arranged at a high position, and the combustion space is relatively sufficient.

3. Fully enclosed membrane water-cooled walls are used around the furnace and the heating surface channel, the furnace has a large cross-sectional area and large volume.

4. Adopts unique flag-type heating surface structure technology, a large number of convection heating surface tubes are led out of the film-type water-cooled wall tubes to form a heating surface like a banner.

5. The grate of the corner tube boiler adopts the scale type or beam type grate, which adopts the isobaric structure of the gale bin. Below the grate surface is a large isobaric chamber. Between the isobaric air bunker and the grate face are several group.

6. Could arrange secondary air on the front wall and rear wall of the furnace according to the different fuel types.

7. Economizer or air preheater is arranged at the rear of the boiler, which can absorb the heat of the flue gas, reduce the flue gas exhaust temperature, save energy, and improve efficiency.
