摘要
The gasifier temperature is a key parameter in the operation of a slag-tapping entrained-flow gasifier.However,there is no effective method for measuring the operating temperature of a membrane-wall-lined gasifier.In this study,a novel robust method for estimation of the online temperature was developed for a membrane-wall gasifier and applied in an industrial SE gasifier.The industrial test results show that the method can estimate the gasifier temperature within 0.04 s,and its value can be reliably obtained.Based on the combination of bench-scale gasifier validation,commercial-scale gasifier operation experience,and the comparison of different simulation methods,the proposed method is accurate and reliable for measuring the operating temperature of a membrane-wall-lined gasifier.
