Features
The heating surface of the boiler is fully fused by argon-shielded welding and X-ray inspection, and the water pressure test is qualified.
Using the unique patented technology, the top of the furnace is equipped with a top coil, and the furnace tube is heated on both sides, which prolongs the residence time of the high-temperature flue gas in the furnace and improves the life of the boiler.
The chain grate realizes automatic coal removal and slag, which is convenient for operation.
Mechanical forced combustion, design special furnace arch, full combustion.
The running speed of the grate is controlled and displayed by the knob, which can be adjusted at any time according to the actual situation to ensure full combustion.
