Key words: associated petroleum gas (APG), gas turbine unit, multi-zone combustion chamber, sustained combustibility, corrosion-active sulfur-containing surroundings.
The article is devoted to questions of APG recycling (wet, gray content and condensate content) in power plants with generation of electricity and thermal energy at marginal fields. To arrange a stable combustion of APG unstable composition and low caloric, on the one hand, and providing a predetermined level of non-uniformity of the temperature field of gas turbine inlet, on the other hand, multizone combustion chamber is developed with the combustion zone and the dilution zones. Settings are defined of single-shaft reducer gas turbine, using low-speed electric generator, which produces electric power 200 kW with consumer characteristics. It was defined regime, geometrical and thermal characteristics of a multi-zone combustion chamber. We carried out thermochemical and thermodynamic calculations to determine the parameters and composition of the working fluid to drive the turbine. Recommendations on the use of heat-resistant and heat-resistant alloys for the manufacture of structural elements of the "hot" path gas turbine. The data obtained can be used in the development of recycling facilities at marginal fields.
