DHL Series Coal Fired Boiler 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.

This series of coal fired steam boiler is a single boiler tube horizontal chain grate boiler with large capacity and wide application range. It is widely used in industrial production field.

The DHL series coal fired boiler is sub-high pressure, combustion chamber arch layout, unique new groove separator patent technology, high boiler thermal efficiency. Especially suitable for grain and oil, chemical industry, papermaking, textile and other industries characteristic process requirements. Its characteristics represent the current coal chain boiler technology frontier. Zozen Boilers can also according to the needs of users, design coal, biomass burning mixed combustion, or biomass burning alone.
