When developing a combustion chamber as a part of recycling micro-gas turbine plants, it is usually performed as a two-zone one. The purpose of this work is to substantiate the possibility of or-ganizing low-temperature stable combustion of a lean mixture in a single-zone combustion chamber as a part of recycling gas turbine power plants. To achieve this goal, the issues of expanding the lower combustion limit due to external heating of the ballasted fuel gas before it is fed into the combustion chamber are considered for the first time. The regime and weight and size characteristics of the fuel gas recuperators included in the installation are also considered. Calculations of the operating parame-ters of the installation showed that with an increase in the supply temperature of the utilized gas to 600...800 K, stable combustion can be ensured at the lower limit at temperatures of 900...1200 K. The characteristics of tubular and plate recuperators along the fuel gas line were analyzed using the availa-ble statistical characteristics. It is shown that in recycling power plants with capacity of up to 200 kW, it is advisable to use plate finned recuperators with thermal power of up to 10 kW and a heat exchange surface of up to 1.7 m2. The studies carried out enables us to formulate the conclusion that organiza-tion of low-temperature stable combustion with external heating of fuel gas makes it possible to de-velop single-zone uncooled combustion chambers as a part of gas turbine power plants. |
