Abstract: Biomass has been considered as an alternative fuel to firing coal in utility boilers because of its vast availability and renewable nature. However, the use of biomass as a full or partial replacement for coal needs a careful evaluation of its impact on the boiler performance and the best approach for implementation. In the past, biomass has been implemented in a cofiring mode and is injected into the coal pipe providing a portion of the heat input. Another approach of utilizing biomass is through reburning.

“…The increasingly grave energy crisis with depletion of fossil fuels and consequent environmental problems are threatening human society. Demand for alternative and renewable energy resources makes co-firing coal with biomass in existing coal-fired boilers a suitable option. Co-firing biomass fuels could effectively reduce net CO 2 and NO x emissions other than the coal consumption. , Despite the advantages, a limitation of its application is the ash-related problems, such as fouling, slagging, and corrosion. , Ash deposition on heat-transfer tubes results in a reduction of plant efficiency and availability . Properties of biomass fuels account for the increased ash deposition propensity.…”

“…The increasingly grave energy crisis with the depletion of fossil fuels and consequent environmental problems are threatening human society. Co-firing of coal and biomass in a utility boiler is a promising choice for generating heat and power. China’s biomass power generation industry is under rapid development. Biomass power generation projects have been conducted in 28 provinces around the country.…”

“…NO is one of the main pollutants generated by the combustion of coal and biomass fuels. Gas reburning is an effective means of reducing NO emissions, and thus, there have been many experimental investigations with the aim of understanding the associated mechanism. Experimental results have shown that the NO reduction efficiency is affected by various factors, including the reburning fuel, the reaction atmosphere, and the temperature.…”

“…Normally, the reburning zone is following the main combustion zone in a coal or biomass combustion furnace. The flue gas temperature at the inlet of the reburning zone is usually higher than 1373 K, while the oxygen concentration in the flue gas is about 2.5–3.0%, a range that equates to suitable air/fuel equivalence ratios in the main combustion zone. , Despite this earlier work, it is evident that further investigations of the reburning process at higher temperatures with varying ethane concentrations but fixed oxygen levels are required because these conditions correspond to the actual ethane-reburning conditions in coal or biomass combustion furnaces.…”
