ABSTRACT:
A conventional air preheater or the conventional design of a preheater is split into two separate sections which are then communicated or connected by a thermally insulated reaction section that is maintained within a predetermined temperature range selected for optimization of heterogeneous chemi-deposition of mercury. The reaction section contains thin stainless steel sheeting which provide an enhanced area of collisional surfaces. Testing has confirmed that this design modification alters the energy heat exchanger to also enhance the oxidation of gaseous elemental mercury in combustion or high temperature source flue gases by providing the surfaces and time for the heterogeneous mechanisms to occur and so control mercury emissions in exhaust gases from coal combustion or other high temperature systems that contain traces of mercury.
