Description
The Aalborg CHB boiler consists of a large furnace welded to vertical, plain-type convection tubes. The low-alloyed plate material is durable against cracking, and it is easy to weld.
Aalborg CHB boilers with a steam capacity of up to 5 t/h have fully water-cooled furnaces. They are constructed without refractory.
The furnaces of boilers with larger capacities are welded using gas-tight membrane water tubes connected to the dome-shaped top of the furnace.
Adequate furnace dimensioning guarantees good combustion, moderate loading and low material stresses. With an efficiency level of approx. 85%, the Aalborg CHB has an economical operation and offers savings in fuel costs.
Due to the standard built-in water washing device, the Aalborg CHB boiler is easy to clean.
Aalborg CHB can operate as a steam drum for an exhaust gas economizer. If the economizer capacity is high, the height of the boiler will be increased accordingly.
