Numerical simulation to study the combustion characteristics of ammonia doped combustion in 350MW W-flame boiler

In recent years, to cope with global warming and reduce carbon emissions, the technology of mixing ammonia into pulverized coal as a carbon-free energy source has received widespread attention. This paper uses a 350 MW W-type flame boiler as the research object. Numerical simulation was used to study the characteristics of combustion emissions from the combustion of anthracite coal blended with 10-30 % ammonia using numerically simulated cloud diagrams and component concentration data. The study shows that with the increase in the proportion of ammonia, the overall temperature of the furnace decreases, the CO 2 concentration decreases, and the NO X concentration increases slightly.
