Description The UNEX 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.
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 CHB has an economical operation and offers savings
in fuel costs. Due to the standard built-in water washing device, the UNEX CHB
boiler is easy to clean. UNEX 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. |
