Processing Woody Debris Biomass for Co-Milling with Pulverized Coal
The USDA, Forest Service, Forest Products Lab funds several grants each year for the purpose of studying woody biomass utilization. One selected project proposed removing small diameter stems and unmerchantable woody material from National Forest lands and delivering it to a coal-fired power plant in Alabama for energy conversion. The Alabama Power Company will test the utilization of the woody...
متن کاملGrindability and combustion behavior of coal and torrefied biomass blends.
Biomass samples (pine, black poplar and chestnut woodchips) were torrefied to improve their grindability before being combusted in blends with coal. Torrefaction temperatures between 240 and 300 °C and residence times between 11 and 43 min were studied. The grindability of the torrefied biomass, evaluated from the particle size distribution of the ground sample, significantly improved compared ...
متن کاملTaguchi approach for co-gasification optimization of torrefied biomass and coal.
This study employs the Taguchi method to approach the optimum co-gasification operation of torrefied biomass (eucalyptus) and coal in an entrained flow gasifier. The cold gas efficiency is adopted as the performance index of co-gasification. The influences of six parameters, namely, the biomass blending ratio, oxygen-to-fuel mass ratio (O/F ratio), biomass torrefaction temperature, gasification...
متن کاملNOx Control in coal combustion by combining biomass co-firing, oxygen enrichment and SNCR
There has been renewed interest in evaluating the effect of biomass co-firing on the multi-pollutant control system such as Selective Non-catalytic Reduction (SNCR) and oxygen enrichment. Emissions savings have been attained by combining SNCR and biomasscoal co-combustion under various oxygen enriched staged air levels. Biomasses with higher tendency of generating CO produced better reduction i...
متن کاملCo-firing Performance of a Retrofitted Oxy-Combustor burning Coal/Biomass Blends: Experimental and Simulation Study
Oxy-fuel combustion is a clean coal technology based on firing fuel in an enriched oxygen atmosphere to obtain a high CO2 concentration in the off-gases. This technology can be combined with the co-firing biomass and the use of blends of coal and biomass can compensate for the fact that the gas properties in the furnace in an oxycombustion process differ from the air-firing case (oxy-firing flu...
