摘要： The present invention provides a combustor for an aerospace gas turbine engine comprising two stages wherein each stage defines an inlet and an exit. The second stage inlet is in fluid communication with the first stage exit such that a first flowpath is defined and it passes substantially through the second stage. A plurality of flow channel tubes is positioned within the second stage and each flow channel tube passes sealingly through a header plate positioned upstream of the second stage inlet thereby defining a second flowpath that also passes substantially through the second stage. The first flowpath exit and the second flowpath exit are positioned adjacent and proximate to one another to provide for the generation of microflames or microflame jets exiting the second stage from between and around the flow channel tube exits. The first stage of the combustor provides a gasifier and a reformer. The present invention also may comprise an igniter for further combustion of the reacted products or an external heat source for start-up. The second stage also may comprise a microflame combustor.

摘要： A method is provided for controlling the operating temperature of a catalytic reactor using a closed-loop system that provides for varying the reactor input and other operating parameters in order to maintain the operating temperature of the reactor at or near the initial setpoint temperature for operation of the reactor. In one example, maximum and minimum operating temperatures with a catalytic partial oxidation reactor are controlled, as well as maintaining control over the corresponding minimum required ratio of oxygen atoms to carbon atoms, such that the operating temperature within the reactor is maintained below the material limits but above threshold temperatures for coking.

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.
