2 pass, fire tube, cylindrical, wet back "REVERSE FLAME" steam boilers.

KBB model boilers are designed and manufactured according to the system which transfers the usable heat of fire and smoke inside the boiler to the water by the 2 pass principle. This model is also known as ‘REVERSE FLAME’.

The size of KBB model is smaller than the same capacity 3 pass boilers which allows an easy installation and decreases the initial investment cost. To increase the boiler efficiency, stainless steel turbulators are placed inside fire tubes. The superior feature of KBB series is the water cooled back and front smoke chambers. This property is unique, cannot be found in any competitive product and increases the efficiency and life time of the boiler dramatically.

The heat transfer area of the boiler is indicated definite and it is the net area along where, the heat is transferred inside the boiler.

KBB model boilers are suitable for operating with high pressure gas and oil burners.

For the high operating pressure values. For the high operating pressure values; the furnace is produced in corrugated form to eliminate the thermal expansions and to obtain sufficient strength. KBB model boilers can be produced for an operating pressure range of 0,5 bar – 18 bar. Boiler is supplied with all necessary accessories, control devices and auxiliary equipment on customer’s request.

Isolation of the boiler is specially made to minimize the thermal energy loss. Special covering plates are used on the surface, to protect the shell of the boiler from outdoor conditions and to prevent tearing.

KBB boiler body consists of: Cylindrical, 2 pass, wet back main body with fire tubes and plain or corrugated furnace at proper thickness, according to the boiler’s operating pressure. EN12953 is taken as reference for design calculations where applicable.
