摘要

Abstract

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.
