>> Introduction
The product is a typical type "D" quick-installed water tube boiler. It consists of upper and lower drums, membrane water wall, convection tube bundle, economizer and condenser. The burner is arranged on the front wall. After the fuel is burned in the furnace, the flue gas is discharged through the convection tube bundle, the economizer the condenser and chimney.
Introduction
>> Features
“D” shaped layout

1. “D” shaped layout

The boiler adopts D-type arrangement and the flame fullness is good.

2. Improve thermal efficiency

Two-stage energy saving devices are adpoted. economizer and condenser are always equipped on the rear or top of boiler,which can reduce the exhaust gas temperature and improve the thermal efficiency. The thermal efficiency can reach to 104% (fuel: natural gas l).
“D” shaped layout
Sufficient output

3. Sufficient output

The boiler has a surplus heating area and large enough steam water space to ensure sufficient and high quality steam output.

4. Membrane wall structure

The furnace water wall and convection flue are all adopts membrane wall structure, which has good sealing performance and reduces the refractory bricks maintenance workload.
