Energy is vital for the social and economic development of any nation. The demand of energy is increasing rapidly world widely with development of civilization and growing industrialization. The requirement of energy demand is met by fossil fuels or conventional energy sources. But due to the depletion of fossil fuels there is an urgent need to effectively tap the non conventional and renewable energy sources. The investigations take place in a 30 MW power plant named Captive Power Plant, Ambuja Cements Limited, Ropar. It is a mini power plant based on biomass. CPP is the internal unit of Ambuja Cements Limited which a pioneer cement production company of India. CPP generates 30 MW of power running on three units. In the present study the measurements were done with both coal-firing and biomass firing with 30% share. The effect of co-firing on boiler performance was evaluated. The influence of various variables such as temperature, stack emissions, steam and flue gas temperatures was investigated. Temperature distribution along the bed was measured with the help of thermocouple. It was observed that due to high volatile content in the biomass, it burnt in the freeboard. So the higher temperature in the freeboard than bed was observed. The boiler performance was not affected by co-firing. In case of co-firing, the emission of gases was within the permissible limits.
