Numerical modeling of biomass combustion in a stoker

while requiring minimal time and effort relative to the traditional experimental approach. In the first part of this work, a comprehensive model was developed to investigate the co-firing of different kinds of biomass including oat hulls, wood chips and natural gas with coal in a stoker boiler located in the Power Plant of the University of Iowa.

Modeling and Experiments of Biomass Combustion in

Modeling and experiments are both done for the grate boiler. The comparison between them shows an overall acceptable agreement in tendency. However at some measuring ports, big discrepancies between the modeling and the experiments are observed, mainly because the modeling-based boundary conditions (BC s ) could differ quite much with the

Furnace - Wikipedia

2021-1-1 · A furnace, referred to as a heater or boiler in British English, is a heating unit used to heat up an entire building. Furnaces are mostly used as a major component of a central heating system. The name derives from Latin word fornax,[1] which means oven. Furnaces are permanently installed to provide heat to an interior space through
