In addition, radiation absorption coefficient had a remarkable effect on maximum combustion temperature and maximum wall heat flux in the new phosphoric acid tower 辐射吸收系数对最高燃烧温度和壁面最大热流影响很大,随辐射吸收系数的增大,最高燃烧温度和烟气出口温度会下降,而壁面最大热流和平均热流会上升。
The predicted results showed that maximum combustion temperature, smog exit temperature, maximum wall heat flux and averaged wall heat flux would increase with increasing phosphorus mass flow rate when excess-air coefficient or air flow rate was constant 模拟结果表明,无论过剩空气系数固定还是空气流量固定,随燃磷量的增大,最高燃烧温度、烟气出口温度、壁面平均热流和最大热流都呈上升趋势。
The effects of parameters on maximum combustion temperature, smog exit temperature, maximum wall heat flux, averaged wall heat flux of a new phosphoric acid tower with circular water wall were discussed, including phosphorus consumption, excess-air coefficient, wall temperature and radiation absorption coefficient, with the mathematical model developed in part 摘要利用已建立的数学模型考察了燃磷量、过剩空气系数、壁面温度、辐射吸收系数对新型燃磷塔的最高燃烧温度、烟气排放温度、壁面最大热流和平均热流的影响。
