Heat Transfer Characteristics in Oxy-fuel Fired Circulating Fluidized Bed Boiler

In an oxygen rich atmosphere circulation fluidized bed boiler furnace heat transfer characteristics,considering the flue gas composition changes,in the calculation of the heat transfer coefficient increases the gas radiation,by bubbling bed heat transfer model as the dense phase zone of a heat transfer model of particle clusters,updating the model as a dilute phase region of the membrane water wall heat transfer model.Research and analysis of operating parameters,such as particle size,porosity,gas composition,bed temperature in combustion conditions on the heat transfer coefficient of effect.
