It is a firing unit in the form of a travelling chain grate mounted under the water tubes combustion chamber. The grate is made of heat resistant special alloy casting materials.
Chain parts are designed to form thin air channels between them, which can provide combustion from the entire surface. The combustion capacity can be maintained at a desired level by providing a number of air ducts and adjustment flaps to the required combustion air beneath the grate.
By using frequency converter in the drive system, the grate speed is automatically adjusted according to the combustion efficiency.
The travelling chain grate unit is delivered as a complete assembly. The steam boiler is placed on the grate unit.
This ensures that the field assembly is completed in a very short time.
