Control of Combustion Emissions

The major emissions from the combustion of fuel are C02, SO, NO and particulates14. The products of combustion are best minimized by making the process efficient in its use of energy through efficient heat recovery and avoiding unnecessary thermal oxidation of waste through minimization of process waste. Flue gas emissions can be minimized at source by  

For a given energy consumption, fuel change is the only way to reduce C02 and SO emissions at source. Fuel switch from, say, coal to natural gas reduces the C02 emissions for the same heat release because of the lower carbon content of natural gas. Fuel change can also be useful for reducing NO, emissions. Once emissions have been minimized at source, then treatment can be considered to solve any residual problems. 

Treatment of SOx. The various techniques that can be considered for the treatment of SO, are  

Treatment of particulates. The various methods for treatment of particulates were reviewed in Chapter 8. These include  

Treatment of C02. If C02 needs to be separated from the other combustion products for the purpose of
