Simulation of Circulating Fluidized Bed (CFB) Boiler Oxygen-Enriched Combustion

Abstract:

In this paper, we focus on the relationship between oxygen-enriched combustion efficiency and oxygen content of primary air under N₂ /O₂ atmosphere combustion on CFB boiler. Firstly, an entirely possible of CFB boiler oxygen-enriched combustion model was proposed. Secondly, a platform was built for simulation of CFB combustion process on XD-APC configuration software. Finally, industrial simulation with industrial data was going on to prove the platform was reasonable. The simulation results were consistent of industrial data. It shows the simulation platform reliability, and the model accuracy. On this basis, coal combustion efficiency was simulated. It shows that the combustion efficiency increases following by oxygen content increasing. It’s economic for real process when oxygen content chooses from 25% to 30%.
