  • Provided with a stationary water washing cleaning system
  • Supplied with rotary cup burner, steam atomizing burner or pressure jet burner

 

Design Data

 

Steam capacity: 0.75 - 15 t/h
Design pressure 10 - 16 bar(g)
Thermal output: up to 10 MW

 

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.
