The influence of furnace shape and size on temperature field in furnace

摘要

The temeprature field in fumace affects the ignition and slagging partidcularities directly.In this paper,on the basis of data about structure,performance design and coal firing of one operating boiler (300MW),the three-dimensional temperature field in a furnace is simulated for five utility boilers that have different shape and size furnaces by the computer-aided test (CAT) method.The results indicate the shape and size of a furnace affect the temperature distribution in the furnace directly,and have great.influence on pulverized-vcoal ignition and slagging characteristics of bolers.Some qualitative laws are also iven for the use in boiler design.
