A flue gas conditioning system uses the waste heat of the flue gas to heat a sulfuric acid solution to add sufficient heat energy to the solution to vaporize the solution before being injected into the flue gas to condition the flue gas so that particulate removal by a precipitator is enhanced.

Flue gas conditioning system using vaporized sulfuric acid

A flue gas conditioning system uses the waste heat of the flue gas to heat a conditioning agent such as water to add sufficient heat energy to the water to generate steam that can be used to atomize the water into a very fine mist with droplets less than 50 microns injected into the flue gas. The fine mist evaporates quickly conditioning the flue gas to enhance particulate removal by a precipitator or filter. Also, humidification of the flue gas causes trace heavy metals--arsenic, mercury, selium, copper, zinc, etc.--to condense on fly ash particles. Such metals are targeted for removal by the EPA under the blanket description 'air toxics.'
