Gas turbine packages of average capacity: the aspects of development

Yuri Rusetskiy, Vladimir Ermolaev – Gas Turbine Engineering Center (Ekaterinburg)

Agas turbine package rated at 45 MW is developed as a part of GTE-45R powerplant. Within GTE-45R powerplant it produces mechanical and heat power. The package can be used as a part of gas turbine heat and power plant to produce electricity and heat and also for conversion of existing heat and power plants into gas turbine combined cycle plants.
The gas turbine is basic for several gas turbine packages rated from 30 to 200 MW developed by Gas Turbine Engineering Center.

Low-temperature radial-axial turbine for waste heat recovery plant

In recent years the interest to combined cycle plants with low–boiling working fluid is growing. The plants are based on the technologies providing the recovery of low-temperature exhaust heat at the facilities of heat and power engineering, metallurgy, chemical and oil processing industries. The question is topical due to possibility of using a gas turbine drive with heat recovery cycle at the plants based on low–boiling working fluid. For high–temperature aircraft and marine gas turbine drives the same technology can be used with an intermediate heat system thus a significant reconstruction of existing facilities like the addition of large waste heat steam boilers is not required. Due to use of the intermediate heat system at gas transportation facilities the control of processes connected with the gas turbine drive variable operating modes is simplified.

About 113 GTK-10I gas compression packages are operated at gas transporting companies of Gazprom now. According to STO Gazprom 2-3.5-039-2005 for this gas compression package NOx concentration in exhaust gas (at 15% O₂) is 230 mg/ncm. The given value exceeds the level of 150 mg/ncm specified in GOST 28 775.

Maintenance of gas compression packages

Andrey Bushuev, Anton Babin – Iskra-Turbogaz

The maintenance system of gas compression packages was formed considering the long-term operating experience of packages in Russia. Its main requirement is to provide safety, working capacity and efficiency of equipment operation as well as the possibility to control the equipment condition during the operating life.
The major customer of gas compression packages in Russia is Gazprom. Gazprom is planning to develop the gas transportation system in Russia introducing new gas lines in the eastern direction and to Europe. Thus the market of gas compression packages is growing, the new modifications of packages are offered. It is also connected with the problems of increasing the reliability and efficiency of gas transportation at the present stage of this industry in Russia.

Energy saving in metallurgical and oil refining industries with Zorya-Mashproekt gas turbine packages

Anatoly Shelestyuk – Zorya-Mashproekt

Zorya-Mashproekt celebrated its fiftieth anniversary in 2004. The company has established all necessary conditions for stable production process and formed an extensive portfolio of prospective equipment orders. The primary activities of the company include development and serial production of gas turbines and turbine packages rated from 2.5 to 325 MW. The fact that 90% of all production volume of the scientific-production complex is exported (75% to the CIS countries) says about a high technical level and competitive ability of the gas turbine equipment manufactured by Zorya-Mashproekt.
However, the vital issue for the company is an exploration and development of alternative markets, especially the electricity generation market.

Solarized gas turbine power systems

Dr. Reiner Buck, Peter Schwarzbözl – DLR, Institute of Technical Thermodynamics

Solar air preheating in gas turbine power plants is a new attractive option for the reduction of CO₂ emissions in power generation. In such a system, the compressor discharge air is heated with solar energy to temperatures of up to 1 100°C. The remaining temperature increase to the turbine inlet temperature is achieved by fuel co–firing. If less or no solar energy is available, nominal operation can be achieved by using more fuel or fuel–only operation. The hybrid operation ensures full plant availability and high capacity factors. Due to the high conversion efficiency a significant reduction in the solar electricity cost can be realized.

Volchansky Agregatny Zavod

The reconstruction of gas transportation systems and introduction of energy saving technologies and equipment determine the future of the industry. The replacement of automatic control systems is an important part of reconstruction. The modernisation of fuel metering equipment is required. The efficiency of a gas turbine engine and the whole package is increased.
Volchansky Agregatny Zavod has been producing control systems for industrial gas turbines since 1982. Modern fuel control valves and shutoff valves, compressor control units compliant with automatic control systems of industrial gas turbines are produced by Volchansky Agregatny Zavod now.

Mobile GTES: Semper in Motu

Oleg V. Bragin, General Director of Mobile GTES, JSC

Mobile Gas Turbine Power Plant (Mobile GTES) was established in July 2006. Company has 12 electric power generating units with the total capacity of 270 MW. Nowadays this unique company provides the reliability of the unified electric power system at the increasing demand in peak power.
We spoke to the General Director of Mobile GTES, JSC about the achievements and the nearest plans.

Combined cycle plants – the do’s and don’ts

Ram Narula, Justin Zachary – Bechtel Power Corporation

Rising concerns about climate change due to global warming are adding to the pressure to use less carbon—intensive technologies. A natural–gas (NG)–based combined cycle (CC) unit emits 55 percent less CO₂ than a coal–based plant partly because of its higher efficiency and partly because NG is a much cleaner fuel with lower carbon content than coal. With natural gas prices hovering around $8 per GJ, it is imperative that these plants be designed for very high efficiency using advanced gas turbines (GTs) and high reliability for not only base load, but also cycling and two–shift operation.
