Introduction

DHL corner tube boiler is field assembled boiler, it uses a piping system as the frame of the entire boiler, and it bears the full load of the boiler, which makes a non-framework boiler. At the same time, this frame also serves as the down comer 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 heat absorbing surface adopts the flag tube structure. The corner tube boiler has the advantages of compact structure, low steel consumption and rapid temperature increase.

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, boiler proper weight is supported by membrane wall and down comer, and all membrane walls are all welded into one whole, with good anti-seismicity.

Complete sealed structure
  • All around the boiler proper is made of welded membrane 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.
