Summary on Grant Application Form
Carboxylic salts of Ca and Mg (e.g. Ca(Ac)2) have shown a greater potential than limestone or dolomite in laboratory-scale tests for the removal of S02IH2S from combustion/gasification system It is expected that twice the removal efficiency can be achieved by spraying fine mists of solution when compared to dry injection (or alternatively around half the quantity of sorbent used to achieve a similar reduction). This is because the cenospheres formed under calcination at high temperatures are highly macro-porous and popcorn-like in structure resulting in increased S02 removal efficiency which is not limited by pore blockage. The study proposed will investigate the efficiency of a dual S02-NOx removal processes by the combined injection of new calcium sorbents and urea/NH3 into combustion plant. The study will hope to demonstrate the cost-benefits and practicality offered by the prospect of near complete, sorbent utilisation coupled with achieving ultra-low NOx emission by the integration of reburn and/or SNCR using urea/NH3. Tests will be undertaken with a conventional air-staged burner and a co-firinglreburn testing facility to evaluate the optimum retrofitting configurations.
