Theory and Calculation of Heat Transfer in Furnaces

Theory and Calculation of Heat Transfer in Furnaces covers the heat transfer process in furnaces, how it is related to energy exchange, the characteristics of efficiency, and the cleaning of combustion, providing readers with a comprehensive understanding of the simultaneous physical and chemical processes that occur in boiler combustion, flow, heat transfer, and mass transfer.

Covers all the typical boilers with most fuels, as well as the effects of ash deposition and slagging on heat transferCombines mature and advanced technologies that are easy to understand and applyDescribes basic theory with real design that is based on meaningful experimental data
