Computer Simulation about Influence of Flue Gas Recycle and Subsection Air on Nitrogen Oxide Formation to Chain Boiler
Numerical simulation is used to study the combustion process，temperature distridution and NOx emission for a 10t/h chain boiler with and without flue gas recycle. And at the same time,it is constrasted that differences when flue gas is recycled to the primary wind inlet and to secondry wind inlet.The results show the temperature distridution decreased with flue gas recycle,so there is less NOx emission.And when flue gas is recycled to secondry wind inlet ,the NOx emission dropped mostly. The result offer a reference to design and operate a chain boiler.
