IN BRIEF #3-2022

Improvement of environmental parameters of Perm gas turbines for the fuel and energy complex of Russia.

In accordance with the scientific and technical policy of Gazprom PJSC, the largest gas concern in the country, in the field of gas pumping equipment, one of the activities of the enterprises of the Perm Motors RPC (JSC UEC-Aviadvigatel and UEC-PM are the part of the United Engine Corporation Rostec) to meet the customer's need for modern high efficiency equipment is to improve the environmental parameters of gas turbine plants. Maxim Snitko, the Deputy General designer and Chief designer of gas turbine drives of JSC UEC-Perm Motors, and Pavel Morozov, head of the department of gas turbine plants for gas pumping units and objects of their application of JSC UEC-Aviadvigatel tell about how this work is carried out.

 

Technical features of reconstruction of compressor stations in modern conditions.

The article gives a brief description of the technical condition of Gazprom's compressor fleet and notes the need to update the company's scientific and technical policy in the field of gas pumping equipment. A brief overview of the history of localization of production of new gas turbine equipment and its results is given. The results of many years of work to limit harmful emissions into the atmosphere are shown. The possibilities of hydrogen energy for the process of natural gas transportation are considered. The current situation requires determining the vector of further development of the technological infrastructure of natural gas transportation system and its compressor element.

 

Top-pressure recovery compressor-free turbines produced by the Nevsky Plant.

Significant electric power demands of enterprises with a full metallurgical cycle can be met through the use of secondary energy resources. Thus, due to the use of excessive pressure of blast furnace gas, it is possible to compensate up to 40 % of the energy needs of the enterprise spent on blast.

The use of schemes with the installation of a top-pressure recovery compressor-free turbine is the most effective technology for such solutions, since it allows to use the pressure energy of the exhaust gas flow without the use of additional fuel. The operation of top-pressure recovery turbines reduces CO2 and other emissions in proportion to the amount of electricity produced without burning additional fuel. The turbine plant is easily integrated into the technological cycle of both newly introduced and existing blast furnace equipment.

 

Combination of EGR and fuel-water emulsions for simultaneous NOx and soot reduction in a medium speed diesel engine.

In this paper the combination of EGR and Fuel-Water Emulsions (FWE) is tested on a prototype two-stage turbocharged six-cylinder 1MW Wartsila W20 Common Rail medium speed diesel engine.

The exhaust gases are recirculated to the intake using a semi-short EGR system, which directs part of the exhaust gases from the high pressure exhaust manifold, through an EGR cooler, to the intermediate

pressure intake manifold before the high pressure (HP) compressor.

The EGR is then compressed to the high pressure intake manifold along with the charge air using the HP compressor. The FWE is performed online using a prototype system which injects the water into the fuel

directly before the high pressure fuel pump.

This leads to no requirements of additional additives to keep the water emulsified in the fuel.

 

Individual manufacture of MOTORTECH components.

The use of high-quality high-voltage equipment in the engines allows manufacturers to achieve maximum performance of their products.

The German company MOTORTECH is a recognized world leader in the production of components and systems for gas engines. Ready-made sets of ignition and automation systems are mass-produced for all engines of MAN, Waukesha, MWM, Caterpillar. But what if your engine was not in the catalog? You will find recommendations in this material. Responding to market demands, MOTORTECH GmbH specialists have developed a program for industrial adaptation of engine strapping elements. We use a high-voltage wire as an example. Different engine models have different plug channel lengths. That is why the high-voltage wire from the MAN drive cannot be applied to the MWM engine, and this is only the first visual difference. In addition, these wires differ in the power carried, the type of attachment to the ignition coil, etc.

 

Development of new generation MET turbochargers.

MHI-MME (Mitsubishi Heavy Industries Marine Machinery and Equipment) developed new generation turbochargers named MET-MBII and MET-ER to respond to the environmental regulations and the market needs.

MET-MBII is axial turbine turbocharger for mainly 2 stroke main engine. MET-ER is radial turbine turbocharger for mainly 4 stroke generator engine. This paper describes the development history and the details of the new MET turbochargers.

 

Modernization of the power station in the village of Sobolevo of the Kamchatka Territory continues.

The power station consists of two Caterpillar's G3516B gas engine power plants, D3512B dual-fuel power plant and one 4-26 DG gas diesel generator set.

The station provides electricity to consumers of Sobolevo and Ustjevoye villages. The installed capacity of the thermal power station is 4670 kW.

The station was put into operationin 1982 and was operated on diesel fuel. In 1999 it was switched to gas. In 2008 two G3516B modular gas engine power plants were added to the equipment.
