In 1963, the Deutsche Bundesbahn (German Federal Railways), together with KHD, studied the situation concerning a successful way of introducing gas turbines in rail-borne traffic. As a result, the Booster Locomotive V 169 (DL 219) was developed and introduced into service in 1965. This application, the first full service locomotive powered by a lightweight gas turbine, was presented to the public in 1965 at the World Traffic Exhibition in Munich and in 1966 at the International Gas Turbine Conference in Zurich, and gave an impulse to various other successful gas turbine applications in railroad traffic. The experience gained with the DL 219 led to the introduction of the DL 210 and VT 602 in 1971–1973. In the meantime, 25,000 hr of experience have been accumulated. Some highlights are presented and discussed in this paper.

Abstract The use of inlet air fogging installation to boost the power for gas turbine engines is widely applied in the power generation sector. The application of fogging to mechanical drive is rarely considered in literature [1]. This paper will cover some considerations relating to its application for gas turbines in ship drive. There is an important evaporative cooling potential throughout the world, when the dynamic data is evaluated, based on an analysis of coincident wet and dry bulb information. This data will allow ships’ gas turbine operators to make an assessment of the economics of evaporative fogging. The paper represents an introduction to the methodology and data analysis to derive the direct evaporative cooling potential to be used in marine gas turbine power output loss compensation.

Reviews the world trends since 1966 in the application of gas turbines on both naval and merchant ships. States that the total horsepower increased from 1.9 to 5.8 million in a four-year period, with some 5.5 million horsepower in propulsion. Indicates a definite growth in commercial use from 100,000 to 390,000 hp. Attributes the significant gain in total power due primarily to the availability of proven engines, that are competitive with other prime movers, in the 20,000 hp and above size. Predicts significant increase in use of the marine gas turbine for naval as well as merchant ships when the overall ship, its utilization and supporting shore facilities are considered jointly.

The World

The profits that can be gained by use of inlet air cooling on gas turbines has been recognised for quite some time now and the systems installed throughout the world have shown the users in the gas turbine field that cooling indeed can be used to boost power at times when the ambient temperature reaches or exceeds the ISO rating temperature of the gas turbine. Drawback however being that the initial investment asked of the gas turbine user is rather large thus only justifying a cooling system in regions where the outdoor temperatures exceed the ISO rating time and again due to the climate in that region. Lately gas turbine users in colder climates have become interested in power augmentation during their short summer, however there is no justification for an investment like necessary when installing one of the presently available systems on the market. As the question reached us from more and more of our clients it stimulated us to go out and search for a low-investment solution to this problem. This resulted in the world’s first low pressure gas turbine inlet cooling system.

High Concentrations

The role and geographical spread of gas turbines is increasing. Because of this, there are more situations where the operator is likely to experience problems with high concentrations of dust overloading the intake system. This work summarizes the causes of dusty winds, areas where they are found, and offers recommendations to assist the inlet specifier. The causes of dusty winds are identified and discussed including desertification, small-scale local factors and meteorological conditions. Areas of the world where dust originates from and areas to which it can be carried are identified. In conclusion, the combinations of these factors are then offered as recommendations for the inlet specifier, to assist in choosing the correct type of filtration for inlets for areas likely to be affected by dust, and identify risk factors with specific types of inlet filter systems in these locations.

Part Presentation

Liquefied Natural Gas (LNG) is expected to contribute in future more than in the past to the overall energy supply in the world. The paper is the first part of a two-part presentation. In the first one, some novel concepts for combining LNG regasification with the generation of electricity are discussed, whereas in the second part advanced exergy-based analyses are applied to the most favorable LNG–based cogeneration system. All concepts to be evaluated in the first part use gas turbines, to keep the overall investment cost relatively low. The comparisons are conducted based on thermodynamic efficiency and on the potential for improving this efficiency.

With deregulation in the power generation market and a need for flexibility in terms of power augmentation during the periods of high electricity demand, power plant operators all over the world are exploring means to augment power from both the existing and new gas turbines. An approach becoming increasingly popular is that of the high pressure inlet fogging. In this paper, the results of a comprehensive parametric analysis on the effects of inlet fogging on a wide range of existing gas turbines are presented. Both evaporative and overspray fogging conditions have been analyzed. The results show that the performance parameters indicative of inlet fogging effects have a definitive correlation with the key gas turbine design parameters. In addition, this study indicates that the aeroderivative gas turbines, in comparison to the heavy-duty industrial machines, have higher performance improvement due to inlet fogging effects. Plausible reasons for the observed trends are discussed. This paper represents the first systematic study on the effects of inlet fogging for a large number (a total of 67) of gas turbines available from the major gas turbine manufacturers.

This article presents an overview of GE’s HA gas turbines that represent the most reliable and efficient machines in the world for converting natural gas into electricity. In a combined cycle arrangement, these turbines provide cost-effective and clean generation that offers reliable electricity to an expanding, global population. The 7/9HA turbine is based upon the original H-class 4-stage gas turbine with exception of simplification by eliminating steam cooling. Metals chosen for the 7/9HA are proven alloys with over 50 million hours of operation on F- and H-class gas turbines. The first 9HA.01 entered commercial operation on June 17, 2016 at the Électricité de France Bouchain plant, located in the Nord Pas-de-Calais region of France. GE followed the Guinness Book of World Records’ definition for a consistent and traceable operating condition for establishing efficiency in world records. Under the oversight of Guinness World Records staff, GE set the record for the world’s most efficient combined-cycle power plant with an efficiency of 62.22% while producing more than 605 MW of electricity.

Two primary topics are addressed in this paper: 1. A brief record of the evolution of U. S. Navy (USN) gas turbine qualification and testing requirements that helped produce the successful engines now in service and 2. Examination of these requirements in light of current and projected defense budgets resulting from changes in the world over the past twenty-five years. The paper proposes changes in the current methods the USN employs in qualifying its gas turbines for surface ship applications. The proposed alternate methods consider commercial testing and service experience as well as testing based on MIL-E-17341 requirements. Finally, the marine gas turbine community is invited to begin a dialogue on the feasibility of these alternate methods.

The rapid growth of metropolitan areas has created the need for high-speed commuter services around the world. The locomotive-hauled train cannot provide the rapid acceleration and fast braking required to move increasing numbers of people over commutation distances. It is being replaced by the self-propelled or ‘multiple unit’ car. This paper describes research carried out by the Metropolitan Transportation Authority, New York, to develop high-speed equipment for commuter services, and deals firstly with electric cars and secondly with a dual powered car taking power from a third rail and also powered by gas turbines. The tests carried out are described and conclusions reached are stated.
