摘要： A control system for a catalytic combustion system on a gas turbine includes a flame preburner, a fuel injector positioned downstream of the preburner and a catalyst positioned downstream of the fuel injector. In such systems, a portion of the fuel combusts within the catalyst itself and the remainder of the fuel combusts in a homogeneous combustion process wave downstream of the catalyst. A sensor in communication with the control system monitors the homogeneous combustion process wave and adjusts the gas temperature at the catalyst inlet to a preferred value based on a predetermined schedule that relates the catalyst inlet gas temperature to operating fundamentals such as adiabatic combustion temperature or the gas turbine's exhaust gas temperature.

摘要： A gas turbo group has a combustion chamber comprising a catalytic burner stage (2), a preburner stage (1) located upstream from the catalytic burner stage, as well as a non-catalytic burner stage (11, 5, 6) located downstream from the catalytic burner stage. The preburner stage serves to always maintain a temperature (T1) at the inlet into the catalytic stage that corresponds at least to a minimum temperature (TMIN) necessary for operating the catalytic burner stage. According to the invention, the gas turbo group is operated so that the burner stage located downstream from the catalytic combustion chamber is taken into operation only when the temperature (T2) at the outlet from the catalytic stage has reached an upper limit in the presence of a maximum combustion air mass flow.

摘要： A pilotless catalytic combustor (10) including a basket (12) having a central axis (14) and a central core region (16) disposed along a portion of the central axis.

A base plate (30) is positioned in the central core region upstream of the exit ends of the catalytic combustion modules, the baseplate defining a recirculation zone (32) near the respective exit ends for stabilizing oxidation in the burnout zone. A method of staged fueling for a pilotless catalytic combustor includes providing fuel to at least one of the modules during start up and progressively providing fuel to other modules as a load on the turbine engine is increased.

摘要： The invention relates to a process, in particular for a process for generating electrical power and/or heat, in which a gas mixture is formed from oxygen, fuel and substantially nitrogen-free inert gas and is burnt in a burner (3). In order to ensure stable combustion even in the case of a relatively high amount of inert gas, the combustion is embodied as flameless combustion.

摘要： The present additional control strategy has been developed to allow the gas turbine to operate at lower load or at other conditions where the total fuel required by the gas turbine is not optimum for full combustion of the fuel. The present invention manages air that bypasses the catalytic combustor and air that bleeds off of the compressor discharge. The bypass system changes the fuel air ratio of the catalytic combustor without affecting the overall gas turbine power output. The bleed system also changes the fuel air ratio of the catalytic combustor but at the cost of reducing the overall gas turbine efficiency. The key advantage of a catalytic combustor with a bypass and bleed system and the inventive control strategy is that it can maintain the catalyst at optimum low emissions operating conditions over a wider load range than a catalytic combustor without such a system.
