A reasonable water circulation loop and a unique return water ejector device (for hot water boilers) increase the water velocity in the riser tubes, preventing water-cooled wall tube rupture.
In-furnace inertial dust separation, supplemented by a high-efficiency multi-tube dust collector, ensures that the boiler's dust emission concentration meets the requirements of Class I areas. The reasonable boiler structure can support its own weight without a steel frame.
The use of an energy-saving, high-radiation furnace arch ensures stable combustion of bituminous or anthracite coal.
The use of high-standard, high-quality auxiliary equipment, accessories, and automatic control devices ensures safe and stable boiler operation while reducing the workload of the boiler operator.
Compact structure, boilers of 1-20t/h (0.7-14WM) can be arranged in a single layer.
