1. The boiler has high thermal efficiency. Due to the reasonable design of the grate structure and precision casting, the scaled grate assembly gap is small, and there is very little coal leakage. There is no need to stop the furnace to replace the grate slices. The air chamber adopts the structure of equal pressure large air chamber and small air door, which has good sealing performance and uniform air distribution. The air supply volume of each combustion section can be controlled to obtain the best combustion state; the enhanced combustion technology is adopted in the front arch radiation area, and the machinery is incomplete The combustion loss q4 is only 7%, and its thermal efficiency is over 82% tested by an authoritative organization, which can bring great economic benefits to users.
2. Safe water circulation. This furnace adopts a unique water circulation structure, the drum is not heated, and the heated water flows in a single direction. In the event of a power failure, the water system does not vaporize, and the water circulation is safe and reliable.
3. No steel frame structure, good seismic resistance: the corner tube boiler adopts a unique water circulation structure, the drum and the weight of the body are supported by the membrane water wall and the down tube, and all membrane walls are welded into one body, which has good seismic resistance.
4. Simple structure. The surroundings of the boiler body are all tailor-welded by membrane water-cooled walls, which are fully sealed with steel structure to prevent air leakage. The upper part of the boiler can be divided according to the transportation limit size. The excess air coefficient behind the heating surface of the boiler tail is only 1.4~1.6, which not only reduces the heat loss of exhaust gas, reduces the power consumption of the induced draft fan, but also greatly reduces the environmental pollution of the boiler room.
5. Furnace wall insulation structure. The outer wall of the corner tube boiler is installed with light insulation material, covered with a composite silicate board, and then reinforced with a metal plate. There is no brick wall structure, and the insulation effect is excellent.
6. The boiler occupies a small area, the overall weight is light, and the infrastructure investment is small.
7. The installation workload is small and the installation cycle is short.
8. The boiler operation control has a high degree of automation, and the operation is convenient and safe.
