The leakage reduction system includes a heat exchanger, a duct arrangement and a separation arrangement. The heat exchanger includes a rotor assembly rotatably mounted along a rotor post. The heat exchanger further includes a second inlet plenum, whereat the duct arrangement is configured. Further, the separation arrangement is incorporated at the duct arrangement dividing thereto into primary and secondary inlets. Through the primary inlet, a flue gas enriched with Oxygen is carried, and through the secondary inlet a recycled flue gas flow is allowed to be carried, keeping the Oxygen enriched recycled flue gas flow substantially away from turnover towards the flue gas flow to avoid turnover towards a flue gas flow, reducing leakage thereof.

A gas to gas heat exchangeris equipped with a heat transfer element cleaning system, effluent collector hopperand effluent collector hopper cleaning system. The heat transfer element cleaning systemis useful to remove accumulated substances from the heat exchangerheat transfer elements. The effluent collector hopperis useful to capture a cleaning fluid used to remove accumulated substances from the heat exchangerheat transfer elements. The effluent collector hopper cleaning systemis useful to remove accumulated substances captured with the cleaning fluid from the effluent collector hopperto prevent clogging thereof.

A heating element is described for a regenerative heat exchanger that is constructed as a profiled steel sheet. The aim of the invention is to produce a heating element that is resistant to acids, has anti-soiling properties and, however, has a good thermal output. To these ends, the heating element is provided with an enameling, and a fluoroplastic coating is applied to the enameled surface.

Heating element for a regenerative heat exchanger and method for producing a heating element

In the production of a catalyst containing a catalytically active Mo--V--O phase, the problem exists of keeping the Mo--V--O phase and/or an Mo--V--Ti--O phase substantially free of other catalytically active impurities in order not to catalyze competing reactions at the same time. For this purpose, the invention provides that vanadium oxide and molybdenum oxide are mixed in a ratio of 0.7 to 1% by weight based on V.sub.2 O.sub.5 and MoO.sub.3, the mixture is heated to a temperature above 500.degree. C., the Mo--V--O phase is cooled, ground and then subjected to a reducing treatment, and dispersed on a heated oxidic support, the dispersed material is then ground, and then applied to a suitable macroscopic support, optionally with further additives, and calcined. Alternatively, the material dispersed on the oxidic support can be kneaded with additives to form an extrudable compound, and the compound can be extruded and then calcined so that the honeycomb bodies produced from the compound have crosspiece widths in a range of from 0.1 to 0.6 mm and cell densities of 50 to 1200 cells per square inch.
