The annual fuel utilization efficiency (AFUE; pronounced 'A'-'Few' or 'A'-'F'-'U'-'E') is a thermal efficiency measure of space-heating furnaces and boilers.The AFUE differs from the true 'thermal efficiency' in that it is not a steady-state, peak measure of conversion efficiency, but instead attempts to represent the actual, season-long, average efficiency of that piece of equipment ...
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.
Home-heating furnaces which use maize kernels as a fuel have a large hopper that feeds the kernels into the fire. [116] Maize is used as a feedstock for the production of ethanol fuel . [ 117 ] The price of food is indirectly affected by the use of maize for biofuel production: use of maize for biofuel production increases the demand, and ...
