3 pass, fire tube, cylindrical, wet back "SCOTCH TYPE" steam boilers.
SBK & TFB model boilers are designed and manufactured according to the system which transfers more of the usable heat to the water to increase the steam production efficiency by the ‘’3 pass’’ principle of fire and smoke inside the boiler. This model is also known as ‘’SCOTCH TYPE’’.
SBK & TFB model boilers are suitable to be used with gas and oil burners.
TFB model boilers have larger steam generation capacities thanks to their double furnace design. This type boilers that have double burner design also provide fuel saving thanks to its steam generation modulation in a wide range.
The exhaust gas temperature is decreased to an optimum level, so the operating efficiency &lifetime of the boiler is increased.
The heat transfer area of the boiler is indicated precise and it is the net area along where, the heat is transferred inside the boiler. (Approximately 40 kg steam is obtained from 1 m2 of heating area.)
The design of SBK type boilers allows to obtain steam, approximately twice in amount, compared with the same heat transfer area of a solid fuel fired steam boiler.
For the high operating pressure values; the furnace is produced in corrugated form to eliminate the thermal expansions and to obtain sufficient strength. SBK model boilers can be produced for an operating pressure range of 0,5 bar – 22 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.
SBK boiler body consists of: Cylindrical, 3 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.
