Biomass is considered to be a major potential fuel and renewable resource for the future. In fact, there is high potential to produce the large amount of energy from biomass around the world. In this study, to obtain basic data for practical application of agricultural and forest by-products as fuel of heating system in agriculture, agricultural and forest biomass resources were surveyed,the pelletizer with capacity of 50 kg ․ h-1 was designed and manufactured and pellets were made by the pelletizer. High heating value, ash content, etc. of pellets made of agricultural and forest by-products were estimated. Straw of rice was the largest agricultural biomass in 2009 and the total amount of rice straw converted into energy of 299×103 TOE. And in 2009, amount of forest by-product converted into energy of 9,579×103 TOE. High heating values of pellets made of stem and seed of rape, stem of oat, rice straw and rice husk were 16,034, 16,026, 16,089, 15,650, 15,044 kJ ․ kg-1 respectively. High heating values of pellets made of agricultural by-products were average 83.6% compared to that of wood pellet. Average bulk density of pellets made of stem and seed of rape, stem of oat, rice straw and rice husk was 1,400 kg ․ m^(-3) (1.4 g ․ cm^(-3)). Ash contents of the pellets were 6.6, 7, 6.2,5.5, 33% respectively. Rice husk pellet produced the largest ash content compared to other kinds of pellets.
Abstract
