AREAS AND STAGES OF DESIGN AND TECHNOLOGICAL SUPPORT FOR ENHANCED PERFORMANCE OF TURBO-EXPANDER POWER PLANTS
View through CrossRef
The paper describes an integrated approach to the design and technological support of enhanced performance of turbo-expander power plants. An analysis of the current state of development of turboexpander power plants has made it possible to establish that traditional approaches have largely exhausted the possibilities of improving their technical characteristics. Moreover, a situation is emerging where, in order to ensure the improvement of such characteristics, it is necessary to involve not isolated design or technological measures, but joint design and technological measures. To implement this approach, the method of generalized parametric modeling is used. At the same time, by combining design and technological parameters, the parametric space in which to search for rational technical solutions for turbo-expander power plants is expanded. This expansion of the parametric space makes it possible to increase the efficiency of the final solution. Such a solution cannot be achieved through design or technological measures alone. The developed approach is implemented in the form of a sequence of solved stages. First, it is a study of the working processes of gas dynamics, heat and mass transfer, and power generation in turboexpander power plants. Secondly, it is the optimization of technological operations for strengthening the elements of these plants. Thirdly, it is the development of real samples of turbo-expander power plants with improved technical characteristics. In general, these stages, which are carried out in a coordinated manner on the basis of the developed generalized parametric approach, made it possible to increase the durability of turboexpander elements by 25-40 % and ensure the efficiency of the detander at the level of 86 %.

Description:
The paper describes an integrated approach to the design and technological support of enhanced performance of turbo-expander power plants.
An analysis of the current state of development of turboexpander power plants has made it possible to establish that traditional approaches have largely exhausted the possibilities of improving their technical characteristics.
Moreover, a situation is emerging where, in order to ensure the improvement of such characteristics, it is necessary to involve not isolated design or technological measures, but joint design and technological measures.
To implement this approach, the method of generalized parametric modeling is used.
At the same time, by combining design and technological parameters, the parametric space in which to search for rational technical solutions for turbo-expander power plants is expanded.
This expansion of the parametric space makes it possible to increase the efficiency of the final solution.
Such a solution cannot be achieved through design or technological measures alone.
The developed approach is implemented in the form of a sequence of solved stages.
First, it is a study of the working processes of gas dynamics, heat and mass transfer, and power generation in turboexpander power plants.
Secondly, it is the optimization of technological operations for strengthening the elements of these plants.
Thirdly, it is the development of real samples of turbo-expander power plants with improved technical characteristics.
In general, these stages, which are carried out in a coordinated manner on the basis of the developed generalized parametric approach, made it possible to increase the durability of turboexpander elements by 25-40 % and ensure the efficiency of the detander at the level of 86 %.
