Boiler

UNIS Power has developed its own unique boiler solutions for broad variety of customer applications. For our fired boilers we use different combustion technologies such as fluid-bed, grate or conventional burner of pulverized coal, oil or gas. We are fully capable to design our boilers for wide range of fuels including biomass, coal, different gases/off-gases, oils and other special liquid fuels. Our waste heat recovery boilers are typically installed behind gas turbines (HRSGs); alternatively for different industrial waste heat utilisation.

The solutions of UNIS Power represent technical perfection and consistent customisation from technical study to final delivery and assembly. Lifetime service is an integral part of our customer assistance including after-sale service, test & diagnostic service or assistance with major reconstructions and operational improvements.
