OP, WP

Type OP boilers are the most widespread design in Polish (and foreign) commercial and industrial power engineering sectors.

These are single-drum water tube boilers with a natural water cycle, based on pulverized hard coal fuel, with dry bottom ash removal.

The furnace chamber is a rectangular box made of membrane walls.

The boiler features air and water preheaters and a steam superheater.

Depending on the boiler size, the pulverized fuel burners are installed in the furnace chamber corners or on its side walls. The boiler includes ignition burners.

CBKK has Type OP design boilers rated between 100 and 650 t/h of steam and installed in the following projects.
