A Biomass Boiler Hybrid Solar Thermal Power System in Computer Aided Design

Two renewable and environmentally friendly energy sources, biomass and solar sources, are compounded. It is an integrated thermal power system that avoids their respective shortages based on the principle of cascade utilization of energy according to energy level. The PPSD, a computer aided design tool, models and simulates the whole system and provides important parameters for designers. The calculation results present that the biomass fuel consumption saving is about 35,904 tons if the hybrid solar thermal power system works 2200 hours in a year for the 48tph biomass boiler. The dropping of flue gas emission temperature to 123°Cincreases the boiler efficiency to 91.45%.
