Abstract:

The article examines the environmental aspects of creating turbo-compressor units for compressor stations of main gas pipelines. The aim of the study is to identify and analyze the main sources of environmental pollution arising from the operation of turbo-compressor units, as well as to analyze modern technical solutions aimed at reducing their negative impact on the environment. This goal is achieved through an analysis of the operational processes of turbo-compressor units, a review of literature sources and applicable regulations, as well as the systematization of many years of experience

Abstract:

An air conditioning system using water as refrigerant (R718) that compresses water vapor with multistage stage variable speed axial compressor with intercooling between stages by water injection is considered. Four stage compression with flash intercooling resulted in 50% improvement of coefficient of performance (COP) at full load compared to conventional refrigerants like R134a. The energy efficiency of an air conditioning unit is specified by seasonal energy efficiency ratio (SEER). SEER is defined as the ratio of cooling output of an air conditioner measured and electrical energy consumpti

Abstract:

In the practice of centrifugal compressor designing, different engineering techniques are widely used because flow motion differential equations cannot be integrated, and Computational fluid dynamics cannot resolve the problem as a whole. Engineering personal computers’ programs are based on experimental data and the gas dynamics theory. The universal modeling method’s (UMM) mathematical model is a set of equations that determine the pressure loss in the elements of the centrifugal compressor flow path. By the earlier versions of the UMM, dozens of process compressors were designed. Several se

Abstract:

Natural gas is transported through a network of main gas pipelines under high pressure, and the process of its consumption requires a decrease in pressure of gas laid mainly in throttling devices. It is beneficial to use part of the available energy potential of natural gas for electricity production by means of expander-generator technologies. However, the task of finding ways to increase the capacity and efficiency of gas turbine power units using the energy of excess pressure of natural gas does not lose its relevance.

The paper provides a theoretical analysis of the operational performance of a marine two-stroke diesel engine in a wide range of modes, operating on a helical characteristic. Reducing the diesel load causes a decrease in the coefficient of excess air for combustion, which is characteristic of two-stroke diesel engines with a relatively high boost pressure. To control the air flow rate, it is proposed to use an adjustable nozzle apparatus as part of a turbine of a turbocharger unit.

The article is devoted to the generally recognized dilemma of using secondary energy resources in the transportation and distribution of natural gas. At stations where throttle devices are used, excessive gas pressure as the main component of secondary energy resources for technological processes is practically not used. Currently, the replacement of throttle devices with turbo-expander units is determined by energy and economic efficiency. This is due to the fact that the use of excess gas pressure in the turbo expander both at gas distribution stations and at compressor stations of gas pipel

Abstract:

This paper deals with the issue of biomass and sorted municipal waste gasification and cogeneration using hot-air turbo-set. It brings description of designed pilot plant with electrical output 80 kWe. The generated gas is burned in secondary combustion chamber located beyond the gas generator. Flue gas flows through the heat exchanger where the compressed air is heated and consequently brought to a micro turbine. Except description, this paper brings our basic experiences from operating of pilot plant (operating parameters, contributions, problems during operating, etc.). The principal advant
