摘要：

In order to reduce overall fuel consumption, or to partially substitute a "valuable" fuel with a poor one, in power plant boilers, oxygen enrichment of combustion air can be very effective. Combustion characteristics of three Chinese pulverized coals, Shenmu bituminous coal, Tianhushan anthracite and Duolun lignite, under the high oxygen concentration upper the 21%, have been investigated using TG/DSC. The results showed that the ignitability, the combustion property, and the burnout were largely improved when added oxygen was used, the suitable oxygen concentration for ignition and steady-going combustion of the pulverized coal flow might be controlled below the 40%. https://link.springer.com/content/pdf/10.1007/978-3-540-76694-0_35.pdf
