Coal and Wood Chips Co-Pyrolysis Study

As a clean, renewable energy, rational use of biomss can effectively solve the problem of energy shortage and environmental pollution. Co-combustion and Co-gasification of biomass and coal are important ways of biomass utilization. Co-pyrolysis reaction is one of the most important processes in the co-combustion and co-gasification. In order to study the different mix ways of coal and wood chips affections on the co-pyrolysis process, TGA was used to study the co-pyrolysis characters of wood chips and coal mixed by different methods with mass ratio 1:1. it is founded out that there is certain interaction between wood chips and coal by the comparison of TGA curves and calculation curves. There is promoting affection at the high temperature if wood chips and coal had been mixed up. There is inhibiting affection if wood chips and coal are tiering distributed.
