【Abstract】 According to the structure design and characteristic of experimental method of high temperature gas-solid suspension reactor, a step-function signal test method was used to determine the dynamic characteristic parameters and obtain the transfer function. The influencing factors of dynamic characteristic were analyzed. The results indicate that the temperature and flow rate are main factors of influencing the dynamic characteristic parameter. The concentration has a little effect on dynamic characteristic parameter suggesting that transfer function can be used to express the relation between the reaction district gas concentration and measured concentration of flue gas analyzer.更多还原
