Product introduction:

SZL series double-drum vertical arrangement chain grate water tube steam boiler, light-duty chain grate match with electrodeless speed regulation device, to make the combustion conditions adjustment more complete, and equip with air blower, induced draft fan to achieve mechanical ventilation.

The fuel fell to the grate from the coal bucket, and along with the grate go into the combustion chamber for burning.The smoke gas flow into convection bundle then pass by smoke baffle wall, the smoke flow S shape to turn. Under the gravity, soot was separated from smoke gas, then fall into the four gravity type automatic dust hopper which set in bottom, then drop into the slag hopper with coal slag when grate moving, discharged from boiler furnace through slag machine.

This kind of boiler with high level automation, safe and stable operation, widely adaptation, high standard smoke and soot emission.

Product feature:

1Convection layout heating surface heat transfer efficiency high, boiler running efficiency characteristics stable and have a certain overload operation capacity.

2Water circulation system reasonable, large capacity, big steam space, good steam quality.

3The cross section ratio of each heating surface and rising tube is reasonable, combustion condition is stable.

4The front arch and back arch is matched reasonable, the furnace temperature is high,

When the coal combustible volatile more than 20,all can be burned.

5Every wind chamber can be artificially adjusted according to fuel combustion stage needed air amount, horizontal wind pressure is consistent. there will be no partial burning phenomenon. Each wind chamber with pulling-type cast iron dust drop door, out of shape not easily, convenient to use, good sealing performance. Boiler thermal efficiency is about 82%.when the carbon content of cinder less than 10%.

6Design multiple smoke baffle wall among the convection bundle, to make the smoke gas of combustion chamber flow into convection bundle for reentry many times.During the reentry, smoke gas soot and smoke baffle wall,convection bundle can scour and crash many times to form vortex, and make use of the inertia and centrifugal force for dust removal, adopt this measure, boiler body initial dust-density emission concentration is lower, help for reducing boiler soot pollution for the atmospheric environment.
