Abstract: The main objective of this research is to make thermodynamics analysis of rice husk fired furnace used in solar-rice husk hybrid steam power plant with moisture reduction of rice husk in Rice Husk Dryer at different temperature before feeding to the furnace. Rice husk is dried by passing flue gas to Rice Husk Dryer in counter flow direction. Feeding with dry rice husk at different temperature was found to increase plant fuel efficiency, to increase in furnace efficiency and to decrease in specific rice husk consumption. The result showed that specific fuel consumption was reduced from 1.761-0.974 kg kWh–1 at 110°C for 50 bar operating pressure on reduction of moisture from 0-100%. Furnace efficiency was found to increase from 52-94.05% at 110°C temperature on moisture removal from 0-100%. Plant fuel efficiency was found to increase from 16.23-29.32% at 50 bar on removing moisture content from 0-100% for drying temperature of 110°C. The efficiency of furnace increased with moisture removal before feeding to furnace was validated with actual rice husk fired furnaces. The difference of results of this research with actual furnaces for efficiency increment with moisture reduction of rice husk were found to be 0.04 and 0.09% only on 25% removal of moisture content.
