摘要:
The present invention relates to a system for utilizing liquid fuels, such as diesel and gasoline, in a catalytic reactor for producing clean heat from the fuel. In particular it relates to a fuel injection system for a catalytic burner (310, 313). It includes preheating elements (308′, 309, 315; FT) for preheating the catalytic burner (310, 313) and primary fuel supply elements (307) for supplying fuel to the catalytic burner (310, 313). The preheating elements (308′, 309, 315; FT) and the primary fuel supply elements (307) are provided in separate compartments (310, 312), the compartments being connected with each other via a channel (CH).
摘要:
Methods and apparatuses are provided for protecting a catalyst (56) within a combustor (30). In one embodiment, a catalytic reactor (14) includes a protective coating (58) that may be chemically removed or mechanically removed while the catalytic reactor (14) is disposed in a combustor (30).
摘要:
A catalytic gas turbine includes a compressor, a catalytic combustor, a turbine, and a flow path conducting a bypass portion of the compressed air around the combustor and turbine. A method of operating the catalytic gas turbine to activate a catalyst in the catalytic combustor includes opening an inlet guide vane upstream of the compressor to a position to produce an increased volume of compressed air. The increased volume exceeds a volume of compressed air needed to support combustion. A bypass portion of the compressed air is extracted and directed around the combustor and turbine. The method may also include extracting a recirculation portion of the compressed air and directing the recirculation portion into the inlet of the compressor.
摘要:
A combuster (2) of a gas turbine engine (1) is fed with liquid ammonia and that liquid ammonia is burned to drive a turbine (3). Inside the exhaust passage of the gas turbine engine (1), an NO x selective reduction catalyst (9) is arranged. Inside the intake air which flows into the compressor (4), liquid ammonia is fed. This liquid ammonia is used to cool the intake air. The NO x which is contained in the exhaust gas is reduced by the unburned ammonia which is exhausted into the exhaust passage by the NO x selective reduction catalyst (9).

A gas turbine system (10) includes a fuel inlet configured to receive a fuel stream (18); an oxygen inlet configured to introduce a first oxygen-containing gas (32, 130); a fuel reformer system (12) comprising: a pre-mixing zone (34, 110) configured to mix a first portion (30, 121) of the fuel stream and the oxygen-containing gas in a pre-mixing device (200, 300, 402) to form a gaseous pre-mix (138); a diffuser (404) configured to provide a thermal shield between the pre-mixing zone and a catalytic partial oxidation zone; a catalytic partial oxidation zone (40, 114, 420) configured to receive the gaseous pre-mix, wherein the catalytic partial oxidation zone comprises a catalyst composition configured to react the fuel and the oxygen to generate a syngas (42, 126); and a dilution zone (116) configured to mix the syngas into a second portion (124) of the fuel stream to form a fuel mixture (48, 136); a gas turbine pre-mixer (16), configured to mix a second oxygen-containing gas (128) from a gas turbine compressor (14) with the fuel mixture; and a gas turbine combustor (20, 500) configured to combust the fuel mixture.
摘要:
A method is provided for low NOx combustion of high hydrogen content and other fuels in gas turbines wherein at least a portion of the fuel is combusted under fuel rich conditions and a portion of resulting reaction heat is transferred to combustion air prior to non-premixed combustion of the fuel.
