DZL Single Drum Coal Fired Steam Boiler 1 Ton For Food Processing Factory

DZL Single Drum Coal Fired Steam Boiler 1 Ton For Food Processing Factory
Brief intrduction of coal fired steam boiler
The DZL series boiler is single drum horizontal type automatic feeding chain grate stoker, water-fire tube boiler. 1-6tph boiler is package boiler and 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat surface and lower part is combustion equipment. By adopting furnace arch, wing-shape flue and threaded smoke tube design , the boiler have the advantages of high thermal efficiency, sufficient output and wide coal adaptability.
Quick Details of coal fired steam boiler

Coal fired steam boiler design features:
1.The boiler has big drum and have big enough space for water. Compared with the SZL series, the DZL boiler is more adaptable to poor water quality. Moreover , when the boiler scaled, it is convenient for maintenance.
2. Adopting convex tube plate, prevent tube plate cracking and simplify the structure of canceling the tension bar.
3. The Wing-shape flue arrangement, the flue gas is three pass, reduce the smoke temperature of high temperature area tube plate, thereby preventing the cracking of tube plate and Boiler tube explosion.
4. Adopting threaded smoke-tube technology, strengthen heat transfer, reduce the number of pipes and the size of boiler shell; reduce the thermal stress at the end of the pipe, and prevent cracking of the tube plate. At the same time, due to the self-cleaning ability of the flue gas in the threaded pipe, avoid the accumulation of dust in the tube.
