Biomass is one of the alternatives fuel of power plants in Japan, following the accident or destruction of the Fukushima nuclear power plant (NPP) in 2011. PKS becomes the favorite choice of biomass power plants there. Most of these biomass power plants use PKS as their energy source, and only a few operate with wood pellets.
The hot pressurized, combustion gases, after transferring most of their hear to the boiler, are passed through cyclones and granulator bed filter, to drive the gas turbine and its generator. The steam produced in boiler goes to steam turbines and condenser in a conventional power plant cycle
