Thermal Design of Boiler Parts

This chapter looks at the thermal design of boiler parts or how steam generator components are sized. First, the main principles of furnace sizing involving specific loading are discussed. Then a simple method to dimension furnaces is introduced. The effects of flue gas velocity, spacing, and fuel type are discussed, and heat transfer sizing is specified, with typical values given. There follows a detailed explanation on how to calculate the heat transfer in a typical boiler surface.
