Automatic Coal Fired Hot Water Boiler Draft Fan Cooling Wall Full Combustion

Product Discription

SZL Series Double Drum Chain Grate Biomass Water Boiler

SZL series double drum chain grate biomass hot water  boiler, boiler host design as double boiler drum longitudinal layout, set steam water separating device in upper boiler drum, set periodic blow-off device in lower boiler drum, there are water cooling wall tubes at left and right side of furnace. Use light chain grate add fuel automatically, the back of furnace is re-burning chamber, convection tubes, the tail of furnace is economizer or air preheater, equip with blower, draft fan for mechanical ventilation, and also equip with slag extractor for slagging automatically. Fuel fall down to chain grate and enter furnace for burning, the flue gas go through furnace, re-burning chamber, convection tubes, economizer or air preheater into tail flue, enter deduster, draft fan and chimney, and finally discharge into atmosphere.

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.

Technical Parameters

Note: the fuel consumption in the table is calculated on the basis of the low calorific value of biomass particles 17084KJ/Kg (4085Kcal/Kg). If the low calorific value of biomass fuel is larger than this value, the corresponding fuel consumption will be more economical than the value in the table.
