MSW oxy-enriched incineration technology applied in China: combustion temperature, flue gas loss and economic considerations.

•The technical and economical analyses of a municipal solid waste (MSW) grate furnace with oxy-fuel incineration technology are performed.•The 25% O2 oxy-enriched incineration retains advantages in the isothermal combustion temperature (Ta) and flue gas loss (q2).•MSW oxy-enriched incineration retains obvious advantages and demonstrates great future prospects for MSW incineration in China.
