IN BRIEF #1-2019Siemens industrial gas turbine plants maintenance and overhaul: all works are performed on the site.
Technical support service concept was developed by Siemens on the base of long-term experience of gas turbine fleet maintenance in different countries. Specific operating conditions of each gas turbine plant stipulate different requirements to the maintenance and overhaul. The primary targets of technical support are keeping operating parameters of the equipment on the necessary level, increasing reliability of gas turbine plants operation, cutting the periods of scheduled and downtimes and extension of the equipment service life. The article presents key aspects of gas turbine plants maintenance which must be taken into account before purchase of the equipment. As an example SGT-700 gas turbine plant maintenance was described.
Advancement of hightemperature turbine nozzle guide vanes cooling systems.
Nozzle guide vanes of up-to-date gas turbine engines operate in extremely severe conditions. Turbine inlet gas temperature is 2100 °С, pressure differential between cooling air and fuel gas is 15 kgs/cm2, gas stream speed is over 400 m/s. Concurrently, the requirements to vanes service life and turbine inlet gas temperature are continuously increasing. It is important to note that to arrange necessary cooling of nozzle guide vanes and to enable their reliable and long-term operation is very complicated task. Aviadvigatel
The New MTU Series 4000 with Advanced Technological Concepts for EU Stage IIIB, EPA Tier 4 and IMO 3 Emission Legislations.
Since market introduction in 1996, Series 4000 engines have consistently demonstrated their reliability over several million hours of operation in Rail, Mining, Marine, Power Generation and Oil & Gas applications throughout the world. The units in 12V, 16V and 20V configuration cover a power range from 1000 to 4300kW.
Low-emission burners for gas turbines with annular-type combustion chambers. Regardless of enough explored theory of gas combustion the problems of receiving of homogeneous fuel-air mixture with its complete combustion at temperatures providing ultra-low levels of nitrogen oxides with creating of high-energy working medium in gas turbines at present are not solved fundamentally. The main problem of domestic engineers is the development of gas turbine hot path and rotor supports operating at high temperatures and flow speed, working medium pressure difference with destroying front of excess pressure and thermoacoustic vibrations.
GTE-110: development and implementation of inlet scroll made from compound materials.
Power engineering industry in Russia feels the need of reliable and effective domestic heavy gas turbines. The only sample of such equipment produced in Russia is GTD-110 gas turbine engine manufactured by UEC-Saturn PJSC. It shows high technical and economic performance but however has a variety of disadvantages detected during field operation.
Conserving ecology: conversion of refrigeration units to the operation with new generation cooling agents.
Reasonability of the investments to service staff training. Investments in staff training require a careful approach. In the issue of servicing of the CHP units the most cost-effective way is an integrated approach that includes three main components, such as long-term service contracts, remote monitoring 24/7 and staff raining. From 25th to 28th of February, 2019, the training organized by TEX group in cooperation with Motortech GmbH was held in St. Petersburg for CHP staff.
Golden lightnings were handed out in Moscow.
The winners of Small power generation - great achievements international prize were announced in Moscow. Grand ceremony of winners awarded were held this year in Congress center of Russian chamber of commerce and industry. |
