Abstract

  The development of new energy sources have been advancing due to global warming and exhaustion of fossil fuels. The biomass fuel is one of these energy sources and is expected from the viewpoint of carbon neutral agricultural and biomass waste recycling and thermal recovery. Bio-coke is an alternate fuel of coal coke and is made by heating organic waste while being compressed at high pressures. The ignitability of Bio-coke worsens by high density. This study was an attempt to produce Bio-coke added with waste glycerin that is generated from the manufacturing process of bio-diesel fuel. The gasification characteristic of the fuels was examined by thermogravimetric analysis, while the stress-strain characteristic was examined by a high-temperature compression testing machine. The ignition and combustion characteristics of the fuels were observed in a fall-type electric furnace. Results show that Bio-coke can be made with the addition of waste glycerin. The gasification of the resulting fuel was promoted with the increase in amount of added waste glycerin. Moreover, the combustibility of the fuel was also promoted and the ignition delay time and burnout time became shorter.
