two drum boilers

Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.

High pressure boilers can be classified as single drum and bi-drum boilers. In early days, the Sterling boilers had four drums, one at the bottom and three at the top interconnected by a bank of tubes. Slowly the three drum and two drum designs evolved. The present day bi-drum boilers are designed for high pressure, flow, and temperature.

The D type boiler can burning oil and gas fuel with high efficiency, which has the advantages of reliable operation, automatic control, clean and environmental protection. Two drum traveling grate water tube boiler can burn both coal and biomass fuel. With chain grate combustion style, the fuel could be burnt fully.
