• No.46 Pyrolysis of Coal in a Downer Reactor with Hot Heat Carrying Particles

抄録

The integrated coal Gasification Combined Cycle (IGCC) has been received a lot of attention because of its higher thermal efficiency than conventional coal-fired power generation systems. To increase thermal efficiency of IGCC systems, triple-bed combined circulating fluidized bed gasifier has been developed. In this reactor, coal pyrolysis occurs with high-temperature heat medium particles in a downer pyrolyzer. In pyrolysis, heat transfer and contacting the heat medium particles with the coal is very important to determine product distribution and reaction kinetics. In this study, we have developed a novel co-current downer pyrolyzer, which can directly contact coal particles with heat medium particles heated in about 900 ℃ using a fluidized bed preheater. We carried out pyrolysis of Loy Yang brown coal and measured gas, tar, char yeilds in the downer reactor by changing feed rate of silica sand (heat medium particles).
