DHL corner tube hot steam boiler

Yingkou lvyuan boiler is A class A boiler manufacturer, mainly engaged in the boiler environmental protection equipment, intelligent control equipment development, and contracts for urban heating, waste heat recovery, atmospheric treatment, energy conservation upgrading and other related projects of investment and general contracting construction.

Main features:

1. Adopt the combustion technology of primary air subsection air supply.Further improve the combustion efficiency.The production of NOx is reduced and low emission is achieved while improving boiler efficiency.

2, the serpentine tube convection heating surface from longitudinal arrangement to horizontal arrangement, reduce the number of elbow, improve the reliability of the convection heating surface, and reduce the installation link.

3, reasonable increase the convective heating surface using Φ 51 coil flue gas velocity, improves the convection heating surface in thermal efficiency, reduces the coil coating.

4. The range of product energy efficiency is 84-86%.

5. Convenient maintenance and less time.
