Influence of particle size of biomass coal on the combustion

Abstract

Wood fuel is an application, causes the reduction of wood resource. Smoke emission from combustion of wood usually make the dirty pot and residence, therefore, four kinds of biomass materials i.e. bagasse, rice straw, rice husk and water hyacinth that used for producing the coal replaces the wood coal. The intluence of particle size of coal is investigated for increasing the flue gas
temperature. In addition, coals after extrusion are tested for burning time, density, compressive strength, flue gas temperature and the amount of carbonmonoxide gas. The experimental results was shown that the smaller particle size affect the higher density and compressive strength. For combustion test of four kinds of coal, it revealed that, nue gas temperature, amount of carbon monoxide gas and burning time are different when the ratios of coal to binder to water for extrusion is constant, depended on the particle size and the kind of coal. In addition, rice straw and bagasse coal provide the nue gas temperature higher than makham wood coal that retail in the general market.
