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.

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.
