木質系ペレットの燃焼特性に関する研究

This study was about the combustion characteristics of woody-pellets. The five materials of pellets as bark, bagasse, straw of rice, pulp sludge and chaff, with the length of 10, 15, 20 and 25mm, respectively were put into an electric furnace (500-1000℃).Then the change of weight was measured until the pellet was burnt out．
The main results about the combution rate were as follows;
(1) The rate was increased with reducing of the length of the pellet．The difference of the rate, however, was little.
(2) The rate of pellets was increased with raising of the temperature of the atmosphere, and extremely increased above 700℃.
(3) The rate according to the different material of the pellets decreased in order of bagasse, straw of rice, pulp sludge, chaff and bark.
(4) The relation between the change of the weight（y）during combustion and the time of combustion（x）was gained as
y=k/(1+a･exp(bx))
and the combustion rate was gained by this equation.
