Abstract
By investigating the parameters and characteristics of flue gas in transition duct of gas turbine as well as the conditions the urea pyrolysis requires,the feasibility of taking use of the gas turbine's transition duct to carry out urea decomposition was demonstrated.Moreover,the relative design parameters were pro-posed.The maximum particle size of the atomized droplets formed during urea pyrolysis is 180μm,at this time the pyrolysis furnace run normally.The gas turbine's transition duct has proper temperature and suit-able droplets'size,which satisfies the requirements of residence time and pyrolysis time the urea needs,so the decomposition of urea can be ensured.By this method,large amount of energy can be saved and the de-nitration process became more safe and economic.关键词
