Controlling emission of pollutants from coal-fired boiler systems. |
摘要 |
<p>In a method of controlling emission of SO x, NO x and particulates from a coal-fired boiler system, that includes a boiler (10), an economiser (12) and a fabric filter baghouse (16), a reagent/catalyst in powdered form is added (26) into the combustion flue gas stream intermediate the boiler (10) and economiser (12) at a temperature below the melting point of the powder. The reagent/catalyst and ammonia (added at 28) are reacted with the SO xand NO x while the flue gas passes through the economiser (12). Further reactio is achieved as the gas is passed through a filter cake which forms on filter bags in the baghouse (16).</p> |
