Abstract

The power generation system using waste as the raw material. This consists of various steps a. Combustible is fed into the boiler for combustion. b. Hi-pressure steam generated in the boiler is fed into the turbine which drives generator leading to power generation. c. Another end of the turbine is connected to a condenser which in turn connected to a cooling tower, and vaccum is maintained in the condenser. d. In another end of the condenser, the condensate is collected and recycled to the boiler through a hot well, and de-aerator and a feed pump. e. Part of the steam is extracted from the turbine at low pressure and fed into air heater to generate hot air for waste drying. This is the principle of co- generation and it increases the over all thermal efficiency of the power generation cycle leading to economic viability.
