3ton 3000kg Industrial High Efficiency Coal Fired Steam Boiler For
Oil Refinery Plant
DZH series steam boiler is manual operation boiler which adopting
manual fuel feeding, manual slag removing. The fuel can be
firewood, wood logs, biomass pellets, peanuts shell, grain shell,
etc. Equipped with special dust collector solution (water film dust
collector, bag type static electricity dust collector, double
towers desulfurization, etc.), it can realize automatic fuel
feeding, automatic ash removing. It is the most popular products in
Southeast Asia, Central Asia, Africa.

Structure
Combustion process:
The fuel enters the furnace and burns on the grate. The flue gas
from the production enters the convection tube bundle on both wings
along the bottom of the boiler barrel through the smoke outlet on
the middle partition wall, enters the threaded smoke pipe through
the front smoke box, passes through the dust collector, and is
pumped and discharged into the atmosphere through the chimney by
the induced draft fan.
Boiler feature
1,Horizontal,3 pass and large furnace
Ensure the sufficient combustion.
The large diameter boiler increase the heating surface to ensure
the high thermal efficiency.
2,The spirally corrugated tube
Strength the heat transfer and improve the thermal efficiency .The
smoke in the tube has the distribution effect,the dust not easy to
deposit ,the tube can cleat by itself.
3,High temperature resistance refractory brick
The furnace wall is poured by the heat resistance concrete and high
temperature resistance refractory brick,decrease heat loss,increase
the boiler thermal efficiency.
4,The economizer
Made of ND corrosion resistance steel,make full use of gas heat
.reduce the exhaust temperature improve thermal efficiency.
