Introduction

HD BOILER DZL series steam and hot-water boiler is the single-cylinder, water-tube assembly, chain grate boiler. Boiler drum is arranged along the center of the boiler longitudinally.Coal economizer is installed at the Rear of boiler.?Fume is absorbed by the hearth, the fume flows to the convection heating surface.Through cooling chamber and exhausts outside through the chimney via coal.Economizer, dust collector and draught fan.
?

Structural features

?

1. Horizontal single drum water pipe chain grate boiler. Is composed of the upper body and lower grate boiler.

2. Longitudinal layout for single drum boiler body, boiler drum with two side water wall tube of the chamber radiation heating surface, regardless of the convective heating surface on both sides of the pipe bundle.

3. Drum internal thread smoke convection heating surface pipe fire tube, tube sheet with low stress without braced arch tube plate.

4. Chain grate points warehouse into the wind, the wind chamber air volume adjustment independently, grate stepless speed regulation.

?


Performance advantages?

1. Boiler for group(fast)form, compact structure, cover an area of an area small, short installation period, less installation cost, infrastructure investment.

2. The tube plate in smoke temperature is low, single return pipe, tube plate heated evenly, tube plate stress low boiler operation safe and reliable, long service life.

3. The arrangement of heating surface, the reasonable fully, boiler heating, pressure rise faster, output full, high thermal efficiency.

4. Grate points warehouse into the wind, the wind room independent adjust air flow, coal bruning evenly, wide adaptability of coal.

5. Safety a high degree of automation, automatic control and monitoring instrument is complete, safe and reliable, easy operation.?
