095283000 | With heating of filter | 8 |
20090071338 | OVERLAP ZONED ELECTRICALLY HEATED PARTICULATE FILTER - A system includes a particulate matter (PM) filter that includes an upstream end for receiving exhaust gas and a downstream end. A zoned heater is arranged spaced from the upstream end and comprises N zones, where N is an integer greater than one, wherein each of the N zones comprises M sub-zones, where M is an integer greater than or equal to one, and wherein the N zones and the M sub-zones are arranged in P layers, where P is an integer greater than one. A control module selectively activates at least a selected one of the N zones to initiate regeneration in downstream portions of the PM filter from the one of the N zones and deactivates non-selected ones of the N zones. | 03-19-2009 |
20090095158 | THERMAL SHOCK RESISTANT SOOT FILTER - A ceramic honeycomb filter having improved thermal shock resistance is comprised of a ceramic honeycomb filter that has a heat absorbing material that undergoes a reversible phase change that absorbs at least in part the heat energy, for example, arising from the combustion of Diesel soot entrapped in the filter. | 04-16-2009 |
20100000410 | APPARATUS FOR REMOVING OF TRACE OF TOXIC SUBSTANCE FROM EXHAUST GAS AND METHOD OF OPERATING THE SAME - An apparatus for removing of traces of toxic substances from exhaust gas, comprising, disposed in sequence from the upstream side in a flow channel of exhaust gas emitted from combustion equipment, a denitration unit including a denitration catalyst layer capable of removing nitrogen oxides from the exhaust gas and capable of oxidizing metallic mercury; an air preheater adapted for heat exchange between air for combustion in the combustion equipment and the exhaust gas; a dust removal unit having a bag filter containing a catalyst for metallic mercury oxidation; and a desulfurization unit for removing sulfur oxide from the exhaust gas. The bag filter may be disposed in advance of the desulfurization unit. Thus, there can be provided an apparatus for removing of traces of toxic substances from exhaust gas that is stable over a prolonged period of time and is highly reliable; and provided a method of operating the same. | 01-07-2010 |
20100050873 | FILTRATION SYSTEM FOR GAS TURBINES - A system for use with an inlet of a gas turbine through which airflow toward the gas turbine proceeds is provided and includes a first stage to remove primary aerosol droplets from the airflow by coalescing the primary aerosol droplets into secondary aerosol droplets, which are larger than the primary aerosol droplets, and to remove solid particulates from the airflow, a second water tight stage, disposed downstream from the first stage, to prevent the secondary aerosol droplets and aqueous solutions of deliquesced particulates, which are not removed by the first stage and which are re-released into the airflow from the first stage, from proceeding along the airflow and to remove solid particulates not removed by the first stage from the airflow, and a third water removal stage, disposed downstream from the second stage, to remove from the airflow the remaining secondary aerosol droplets leaking from the first and second stages. | 03-04-2010 |
