| 20100202948 | Reverse Flow Reactor - A reactor cools humidifies gases produced by combustion or the like. The reactor has a chamber with an inlet at a lower end to receive a flow of gas, and an outlet at a upper end. The gas flows in a generally upward direction through the reactor. The horizontal cross-section of the chamber increases with height and the flow velocity of the gas decreases as it flows upwardly. The reactor includes at least one device for injecting water droplets into the upper region of the chamber, counter to the gas flow. As the water droplets fall, they gradually evaporate and lose mass and encounter a counterflow of increasingly higher velocity and temperature until the force of the upwardly flowing gas is sufficient to reverse their flow and carry them in an upward direction. | 08-12-2010 |
| 20100142314 | Particle Interactions in a Fluid Flow - Interaction between two different species of particles in a fluid stream is promoted by generating turbulent eddies in the fluid stream. The turbulent eddies are designed to be of such size and/or intensity that the two species of particles are entrained into the eddies to significantly different extents. Consequently, the different species of particles follow different trajectories, and the likelihood of collisions or interactions between the particles is increased. Optimum collision rates will occur for a system which maintains a Stokes Number (St) much less than 1 for one species, and or order 1 or greater for the other species. The invention has particular application in air pollution control, by promoting agglomeration of fine pollutant particles in air streams into larger particles to thereby facilitate their subsequent removal from the air streams. | 06-10-2010 |
| 20080264249 | Precipitator Energisation Control System - The energisation of an electrostatic precipitator is controlled in order to reduce arcing and/or back corona between the precipitator electrodes, using the precipitator current as a feedback parameter. A high speed switching device is used to control the energisation of the precipitator electrodes so that the precipitator current is regulated to a desired level with a response time that is significantly less than the arc generation time constant. The energisation is controlled so that the precipitator current is regulated to a predetermined value below the current level at which arcing occurs. The energisation response is proportional to the severity of the arcing, which can be based on the power and frequency of arcing. If back corona is detected, the energisation can also be controlled to reduce back corona. | 10-30-2008 |
