The sulfation rate of reagent-grade monocalcium silicate is of the same order of magnitude as that of limestone and higher than that of reagent-grade calcium oxide.

Flue Gas Desulfurization at High Temperatures: A Review Article (PDF Available) in Environmental Engineering Science 21(4) July with 1, Reads How we measure 'reads'. In this process, acid gases are absorbed by organic solvents with high solubility of the acid gas components. The Selexol process typically operates at 39 °C, and the sulfur level can be reduced to 10–15 ppm v or lower if refrigeration is used, in which case the . A study has been conducted on the utilization of calcium silicates and the silica supported lime as regenerative sorbents for desulfurization of hot combustion gases. Except for γ‐Ca 2 SiO 4 and Ca 3 SiO 5, all the calcium silicates and the silica supported calcium oxide are equally or more reactive than calcium oxide, and the regeneration. To achieve complete combustion, gases produced must remain in the high-temperature zone of the furnace for a minimal residence time, usually seconds. Achieving that residence time is usually accomplished by designing the furnace to retard the upward flow of gases, for example, by installing irregularities into the furnace walls.

C. Shaddix, A. Molina, in Oxy-Fuel Combustion for Power Generation and Carbon Dioxide (CO2) Capture, Introduction. Oxy-fuel combustion of coal produces various changes in the combustion process itself. These combustion-related effects are manifest in coal ignition and coal char combustion and burnout and thus play important roles in the practical consideration of flame stability . The RRT combustion system is composed of numerous circular-ceramic regenerative burners, each being equipped with a small four-way reversing valve and its control system. Inside the burner the regenerator is adapted to complete heat exchange between the high-temperature flue gas and the combustion . The principle of a regenerative cycle is to recover some of the exhaust heat and transfer it to the combustion air. This can only be achieved if the turbine exhaust temperature is greater than the compressor exit temperature, and therefore implies that the optimum cycle pressure ratios are lower than those of the optimised simple cycle gas turbines, as discussed in Section To comply with environmental regulations, a high fraction of the sulfur must be removed from the product gas stream. Calcium-based sorbents are the prime candidates for in-bed capture of sulfur. The removal of sulfur takes place through the reaction of hydrogen sulfide with calcium-based sorbent and produces calcium sulfide, which is not stable.
