Thailand is an agricultural country make a lot of agricultural products as a result, a number of agricultural wastes. These wastes can be used to produce fuel pellets compressed. Agricultural waste material through the digestive to be small and dehumidification. Then the pellet and briquette low temperatures. Stored in silos to retain moisture. Moisture to be between 8-15 % and a high heating value suitable for use as fuel in steam generator or used in industrial furnaces. This study will evaluate the efficiency of the combustion of biomass fuel pellet. This study will evaluate the heat down on the moisture content increases. The study will calorific value of biomass pellet production. Ash from burning. It is caused by the moisture content of biomass fuel pellets. The study found that This study will be useful for the development of technology for biomass utilization of agricultural residues and can develop the potential of renewable energy further.
