Judgment method to co-combustion characteristics of pulverized coal and biomass blends at constant temperature

The co-combustion of pulverized coal and biomass blends at constant temperature was carried out by thermogravimetry experimental system in tube furnace. The parameter 'mass remain' was introduced, and the parameters 'overfire share', 'burnout time', 'steady factor' and 'uneven index' etc. were put forward to judge and analyze the experiment results in different blending ratios, coal types and temperatures. The results show that the judgment method not only can reflect the co-combustion characteristics of pulverized coal and biomass blends at constant temperature in weightlessness process, but also can investigate co-combustion effects based on the distribution difference of weightlessness between at earlier stage and at later stage of the whole weightlessness process. ©, 2014, Taiyangneng Xuebao/Acta Energiae Solaris Sinica.
