摘要： A method is provided for achieving low NOx in the operation of a non-premixed combustion system by reacting a fuel-rich mixture to produce partial reaction products plus heat, transferring a portion of the heat to a bypass air stream, and passing the cooled partial reaction products into non-premixed contact and combustion with a stoichiometric portion of the heated bypass air stream. A supply of fuel and a supply of air is provided; and a fuel-rich mixture is formed and reacted to produce partial reaction products plus a heat of reaction. A portion of the heat of reaction is transferred to a bypass air stream and the cooled partial reaction products are passed into non-premixed contact and combustion with a stoichiometric portion of the heated bypass air stream.

摘要： A system and a method for improving the thermal efficiency for power production from coal is provided. The system utilizes a gasifier reactor for the conversion of coal to a hot high-pressure fuel gas wherein the fuel gas contains carbon monoxide and hydrogen. The system includes a flow chamber to mix the fuel gas with an oxygen-containing gas to produce a combusted fuel rich product gas that is then passed to a turbine engine connected to the flow chamber. The turbine engine defines a turbine exhaust duct to feed exhaust gas to a reheat combustor and a heat recovery boiler connected to the reheat combustor provides steam to a steam turbine system.

A feed stream comprising a compound to be alkylated admixed with a minor amount of an olefin is introduced into the flow channel wherein the flow channel is of sufficiently long configuration to have a mass-transfer-limiting boundary layer. The feed stream is contacted with a catalyst positioned on an inner surface of the flow channel thereby reacting the compound with the olefinto produce an alkylate product.

摘要： The invention provides a method for operating an oxygen blown integrated coal gasification combined cycle gas turbine (IGCC) system having a gasifier and an air separation unit. A supply of low pressure nitrogen is passed to a gas turbine compressor along with sufficient air to provide sufficient compressed air to the gas turbine combustor for gasified fuel combustion. Subsequently, at least a sufficient portion of the compressor discharge flow is passed to a combustor for combustion of the gasified fuel flow to the combustor. The gasified fuel is combusted to produce hot combustion gases and then the combustion gases are passed to a turbine.
