| Abstract: | Composite lining made of water-cooling pipe and refractory lining is used in the new type opposed-nozzles-gasifier for coal-water-slurry.Because of the high temperature and pressure in gasifier the refractory lining is corroded severely,which is an important factor affecting the life of refractory lining.Therefore,optimized structure design of composite lining in gasifier will make full use of its quality.In this paper,a mathematic model of heat transfer calculation in gasifier is built and the computer program is used to solve this mathematic model and we also get the temperature distribution by calculating on some actual technology parameters.The result indicates this mathematic model can get the temperature distribution of composite lining,and can provide theoretic foundation for the design,opertation and maintenance of composite lining. |
