    摘要: A boiler conveys an exhaust gas stream to a heat recovery device. The heat recovery device includes an air straightener, a heat recovery unit or feedwater heater, and a catalyst assembly positioned between the air straightener and the feedwater heater. The catalyst assembly has a catalyst drawer or bed that holds a quantity of catalyst materials for removing contaminants from the exhaust gas stream. The air straightener has a plurality of baffles that are arranged in a manner that optimizes the performance of the catalyst drawer or bed. The baffles also prevent condensation from leaking from the feedwater heater into the boiler. The feedwater heater recovers a quantity of heat from the exhaust gas stream.

    摘要: A group of at least two gas-flow reactors (21, 22, 2′2, . . . , 2n, 2′n) preferably with an ascending gas flow (3), are supplied in parallel with gas and with a chemical neutralization and/or sorption agent of the pulverulent material type capable of adsorbing effluents present in the gas flow by bringing the chemical neutralization and/or sorption agent in contact with the gas flow, the at least two reactors having elements (10) for collecting the chemical neutralization and/or sorption agent after contact with the gas flow. At least one of the two reactors has elements (11) for discharging the chemical neutralization and/or or sorption agent, after contact with the gas flow, these discharge elements being connected to the collecting elements, and members (7, 16) for injecting the chemical neutralization and/or sorption agent into at least one other of the at least two reactors.

    摘要: A selective catalytic reduction process with a palladium catalyst for reducing NOx in a gas, using hydrogen as a reducing agent. A zirconium sulfate (ZrO2)SO4 catalyst support material with about 0.01-2.0 wt. % Pd is applied to a catalytic bed positioned in a flow of exhaust gas at about 70-200° C. The support material may be (ZrO2—SiO2)SO4. H2O and hydrogen may be injected into the exhaust gas upstream of the catalyst to a concentration of about 15-23 vol. % H2O and a molar ratio for H2/NOx in the range of 10-100. A hydrogen-containing fuel may be synthesized in an Integrated Gasification Combined Cycle power plant for combustion in a gas turbine to produce the exhaust gas flow. A portion of the fuel may be diverted for the hydrogen injection.
