Abstract:
In this reseach of power plant, the bio-fuel cost are increasing. Due to the business is grow.The main bio-fuel of power plant is rice husk which is demanded in bio-fuel power plant business. It is effect to cost of electricity generated. There are also problems with uncertainty of bio-fuel quantity in seasonal variation or agriculture. In this research, using a mathematical analysis model (Mathematical Model) for proportion of bio-fuel used to produce electricity. According to the agricultural season, the object that is the lowest cost of bio-fuel per electricity equivalent (baht/kwhe) and the scope of decision making depand on the quantity which are vary in agriculture. Total moisture of fuel not exceeding the value of the machine design and the energy sufficient to produce electricity. In addition, the researcher made an analysis of the project investment for reducing the fuel moisture content of fresh eucalyptus bark by a feasibility analysis. The results showed that the ratio of bio-fuel to be appropriate to reduce the cost of electricity from 1.55 baht/kwhe reduced to1.29 baht/kwhe and analysis of the project investment, reducing the fuel moisture content of fresh eucalyptus bark found that reducing the fuel moisture using moisture in the steam dryers are the most worthwhile investment.
