Downfired boiler having vertical heat transfer tubes - MOSCONE; …

16/10/1992 · It has been found, that by redesigning the tube-shell water-heating boiler, so that the heat transfer tubes are oriented vertically, instead of horizontally, the heat transfer efficiency is measurably improved. Typically, an efficiency increase of about ten (10) percent is achieved. In constructing the boiler, the preferred material to use is

Fluidized bed combustion - Wikipedia

FBC smoke tube boiler Fluidized bed combustion ( FBC ) is a combustion technology used to burn solid fuels . In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.
