DZL Series Chain Grate Biomass Fired water Boiler

The new type of DZL series steam boiler is a single drum-type boiler with water-fired tube shell, and the combustion equipment is a chain grate. The water wall on the left and right sides of the furnace is a radiative heating surface, the lower part of the boiler tube adopts a new technology of cross arrangement, the two wings of the furnace are convection heating surface, and a threaded flue pipe (57 × 3) convection heating surface is arranged in the pot tube. The heat-resistant concrete is adopted in the furnace wall, and the outer part of the boiler is a three-dimensional guard shell.

The boiler body adopts the form of upper drum, water-cooled wall tube and header left-right symmetrical arrangement, and the lower water-wall tube of boiler adopts the new technology of cross arrangement. The drum consists of 1600 × 14 tubes and 1600 × 14 front and rear tube plates. The water cooling wall tube is a 57 × 3 boiler tube, the header is a 159x6 boiler tube, and the falling tube is a 133x6 boiler tube. There are front and back arches in the furnace of this boiler, and the combustion efficiency is high.

Product Features

1. Installation convenience:

The boiler is generally fast-loading factory, easy to transport and on-site installation, greatly shorten the construction cycle, save installation costs, so that the boiler can be put into production in time.

2. Reliable operation:

Boiler heating surface layout is reasonable, water circulation is smooth, and each heating surface is cooled in time, so as to effectively ensure the safe operation of the boiler.

3. Maintenance and repair convenience:

Boiler drum set up manhole, can enter inspection repair. It is convenient to open the smoke box in front of the boiler, and the personnel can check it easily and clearly, which provides a good condition for correct treatment.

4. Full combustion:

With the secondary air and reasonable furnace design, the fuel can be fully burned and the black smoke can be eliminated.

5. High efficiency grate:

Boiler grate adopts double side ventilation, which is brought naturally to the front end of boiler row by dust cleaning technology, which avoids air leakage, fuel leakage and uneven ventilation, and is easy to operate, and has obvious advantages compared with ordinary grate.

6. Convenient ash cleaning:

Many ash cleaning holes can be set up on the boiler, which can remove ash in time and effectively, avoid the trouble of operation and decrease of thermal efficiency caused by boiler ash accumulation, and ensure the stability of boiler load.
