| 20110005706 | Method for Online Cleaning of Air Preheaters - A method of cleaning air preheaters of the type having a rotor which passes through a stream of flue gas and a stream of intake combustion air is disclosed. A soot blower is operated in step-wise fashion to blow a soot blowing medium through passageways in the rotor. The passageways are arranged in concentric rings and move at a tangential velocity which depends on the speed of the rotor and the location of the passageway relative to the center of the rotor. In the present method the speed of the rotor is adjusted in accordance with the position of the soot blower so that every passageway moves over the soot blower at the same or substantially the same tangential velocity. | 01-13-2011 |
| 20100037678 | Method and Apparatus for Detection, Measurement and Control of Sulfur-Trioxide and Other Condensables in Flue Gas - In a method of determining amounts of condensable species present in a gas containing condensable species a probe is placed into a gas containing condensable species. The probe has a plurality of spaced apart contacts on an outer non-conductive surface. That surface is heated at a selected heating rate and then cooled at a selected cooling rate over a selected time period. During that time period current flow between the contacts and the temperature of the non-conductive surface is monitored over the selected time period. Peaks in a plot of the current flow over the selected time period and the temperature for the time corresponding to each peak are then correlated to the condensable species has a kinetic dew point at each identified temperature. The identified temperature for each identified species is compared to a predetermined correlation of dew point temperature and concentration for that species to determine the concentration of that condensable species present in the gas. | 02-18-2010 |
