Advantages of Industrial Steam Boiler
1. Adopting the new-type structure
The new-type structure steam boiler adopts single drum vertical
type arrangement, and two sides of the furnace are arranged with
water cooled wall. The upper part is welded with the boiler drum,
and the lower part is welded with the right and left container. The
back arch and the drum space are arranged with convection bank,
whose upper part is welded with boiler drum, and whose lower part
is connected with all containers. It is the compact structure.
2. Organizing the fire in the furnace reasonably. The furnace
adopts double layers anti-burning structure which is formed by the
pre-combustion chamber and combustion chamber. As for the boiler
design, dividing the furnace into the pre-combustion chamber and
combustion chamber, which is good for strengthening the fuel
burning, and decreasing flying ash fuel and flying ash content.
3. Among the convection tubes, there are many smoke baffle walls,
which can make fire turning-back many times and are good for
removing the dust of the furnace. Boiler itself has a dust removal
function, so that dust emissions from the boiler to reach the
target state environmental regulations. This series of boiler
adopts arched tube plate, two-wing flue pipe etc, thread, solve the
smoke pot shell boiler tube plate cracking, the bulge, tube boiler
water-cooled wall tube, thermal efficiency is low, the coal output,
adaptability, etc.
