SKK – SCOTCH TYPE HOT / SUPERHEATED WATER BOILERS-25677
Product Code: SKK
SKK SERIES
Heat generation capacity: 232 kW - 14535 kW
Fuel Type: Natural Gas, LPG, Diesel, Fuel Oil
SKK model boilers are designed and manufactured according to the system which transfers more of the usable heat to the water to increase the hot water production efficiency by the ‘’3 pass’’ principle of fire and smoke inside the boiler. This model is also known as ‘’SCOTCH TYPE’’.
SKK model boilers are suitable to be used with gas and oil burners.
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 25000 kcal/h heat is obtained from 1 m2 of heating area.)
For the high operating pressure values; the furnace is produced in corrugated form to eliminate the thermal expansions and to obtain sufficient strength. SKK model boilers can be produced for an operating pressure range of 0,5 bar – 22 bar. Boiler is supplied as packaged 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.
SKK 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.
