3 PASS HIGH EFFICIENCY SEMI CYLINCRICAL SOLID FUEL FIRED STEAM BOILERS

YSB model boilers are designed and manufactured according to the well known, three pass design that allows obtaining adequate heating surface and lower exhaust gas temperature compared with two pass design. The half cylindrical compact design brings installation and cost advantages without any sacrifice from heating surface.

YSB model boilers are specially designed for high efficiency at operating pressures up to 5 bar. For higher operating pressures (up to 10 bar) special production can be carried out, up on customer’s request.

The indicated heat transfer surface for each capacity is completely correct and it shows the net area along where the heat is transferred to water inside the boiler.

20-25 kg/h steam is obtained from 1 m2 heating surface. Boiler is supplied with all necessary accessories, control devices and auxiliary equipment on customer’s request.

A wide range of fuel types such as; wood, coal, olive seeds, pellets, nut shells and other types of biomass can be used with this model along with traditional solid fuels like coal. By implementing an automatic stoker feeding system or an automatic water cooled vibrating grate to the boiler, small sized solid fuel types are easily used for firing.

Isolation of the boiler is specially made to minimize the thermal loss. On the surface; special covering plates are used to protect the outer shell from weather conditions and tearing at maximum level.

Boiler consists of a half cylindrical, 3 pass, fire tube, wet back main body and furnace at proper thickness, according to the boiler’s operating pressure. EN12953 and TS497 is taken as reference for design calculations where applicable.
