DHL Series Coal Fired Steam Boiler

Overview

Brief 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.

Features

1. Lengthened grate: The length of front and rear axles of grate is longer than that of the same type of domestic products, which prolongs the combustion time of fuel in the furnace, makes the coal combustion sufficiently, reduces the carbon content of slag, enlarges the effective area of grate, and obviously enhances the overload capacity of boiler.

2. Bilateral air inlet: six separate air chambers are arranged along the longitudinal direction of the grate. Each air chamber has an independent air conditioning device which can adjust the air volume of each air chamber separately to achieve the best combustion control effect.
