The Numerical Simulation of Combustion on Vinegar Residue in a Biomass Boiler

Abstract:

Numerical simulation had been used to study the combustion characteristic of vinegar residue in a straw-fired boiler in this paper. Achievement of the paper was based on a kind of CFD. The results paid more attention to the following points: the influences of different loads and the flow ratio of primary air and the second air on the combustion condition, the gas phase concentration, and mean mixture fraction. The results showed vinegar residue was easy to burn out. The increase of load was helpful to the combustion of vinegar residue in the straw-fired boiler. It was reasonable when the ratio of primary air and the second air is 1:1. And the straw-fired boiler showed good combustion adaptability to vinegar residue.
