The role of fuel additives to control environmental emissions and ash fouling
The main objective of the project was to test the effectiveness of available additives at reducing ash fouling, slagging and NO(x) and/or SO(2) emissions in fluidised bed combustion (FBC), stoker fired and PF combustion. The project also investigated the mechanisms involved in cases where the additive alleviated the problem. Seventeen fuel additives were selected for this study, chosen to cover the range of additive formulations available in the United Kingdom that claimed to reduce fouling/slagging or emissions. They were characterised using chemical techniques and XRD and their effect on a kaolinite/sodium reaction was studied in thermal interaction experiments. The effect of the additives on alkali bonded fouling and emissions was also investigated using a 9 kW and a 150 kW underfeed stoker and a laboratory scale FBC. The study concluded that, in general, the claims made for fuel additives were not justified.
