Abstract

Nitrogen oxide emissions during the fluidised bed combustion of coal have been investigated in order to determine the factors which affect the quantity of NO and N(2)O produced during combustion, and to understand the mechanisms of their formation and reduction for modelling purposes. A better knowledge of the chemistry of NO and N(2)O formation and reduction could lead to methods for reducing emissions and improving the environmental impact of FBC. The principal investigations have focused on the following topics: (i) factors affecting NO and N(2)O emissions such as temperature, oxygen to fuel ratio, coal type, nitrogen content, volatile matter and coal size; (ii) the formation of NO and N(2)O from devolatilised coal chars; (iii) the effects of limestone and dolomite on fuel nitrogen oxidation; (iv) methods of reducing NO and N(2)O; (v) reaction mechanisms, networks and modelling.
