  • Product Details

  The corner tube boiler uses a piping system as the skeleton of the entire boiler, and it bears the full load of the boiler, which makes a non-framework boiler. At the same time, this skeleton also serves as the down tube of the boiler and upper and lower headers. The boiler drum is an external type drum, the furnace is a fully enclosed membrane wall structure, the convective heating surface adopts the flag structure. The corner boiler has the advantages of compact structure, low steel consumption and rapid temperature increase, which makes the boiler very popular. The boiler is field assembled boiler.

Technical advantages:

  Safe water circulation: The boiler adopts a unique water circulation structure, the drum is free from heat and the heated water flows in one direction. In the event of a power outage, the water system does not vaporize and the water circulation is safe and reliable.

  Anti-seismic Structure: Corner tube boiler adopts non-framework structure, body weight is supported by membrane water wall and down tube, and all membrane walls are all welded into one whole, with good anti-seismicity.

  Complete sealed structure: All around the boiler body is made of welded membrane water walls, and the steel structure is completely sealed to prevent the occurrence of air leakage. The upper part of the boiler can be divided according to the size of the railway transportation limit. The excess air coefficient after the heating surface of the boiler tail is only less than 1.2, which not only reduces the heat loss of the exhaust fumes, reduces the power consumption of the induced draft fan, but also greatly reduces the environmental pollution of the boiler house.
