Industrial Gas Turbine

The development of a derivative small industrial gas turbine, sometimes termed a “microturbine”, is described. The target markets were the oil and gas upstream and midstream markets, and combined heat and power applications. These applications defined the product objectives. A general description is presented of the baseline recuperated gas turbine from which the new gas turbine is derived. The new gas turbine is a 333kWe recuperated gas turbine with a modernized compressor, variable inlet guide vanes for improved part-power efficiency and emissions, and an improved hot-section. The applicability and advantages of the GT333S features are compared with the market requirements. The development program included compressor rig testing, inlet guide vane development and testing, and engine testing. For the new product, a large number of components remained unchanged from GT250S, including most of the drivetrain. This provided confidence that the reliability of the GT333S, based on the millions of successful operating hours accrued on the GT250S, would translate into good GT333S reliability and availability. Extensive factory testing was performed to demonstrate the robustness of the new engine. The final performance results showed that the gas turbine achieved the program objectives. Some lessons learned from the development program are described.

The U.S. Navy is developing an intercooled Recuperated (ICR) marine gas turbine, designated the WR-21, for propulsion of future surface ships. The objectives of this development program and the key technical requirements are summarized. The design of the WR-21 is described in considerable, detail. Meeting all of the design requirements for performance, space, weight, reliability, maintainability and life has been challenging. Numerous design tradeoffs and iterations have been performed to optimize the design within the constraints imposed in the ICR technical specification. Integration of the WR-21 engine into the DDG51 Flight IIA ship, which is the U.S. Navy’s first application, has influenced the WR-21 design. This paper discusses the aspects of the DDG-51 application that were factored into the design of the ICR engine in order to reduce installation costs.

This paper is a report on the design and development of a small regenerative gas turbine and on the component technology involved in this development. It is shown — on the basis of test results — that the gas turbine is a potential competitor of the Diesel engine for powering trucks, if the economy of the gas turbine can be improved. Future development work must therefore be aimed at improving the efficiency of the individual components and at applying ceramic materials in the hot parts of the engine.

Complex open gas turbine cycles are analyzed by applying the heat balance method presented in Part I of this paper. Reheating, intercooling, regeneration, steam injection, and steam cooling are evaluated graphically to give a visual perspective of what takes place in terms of the overall heat balance when such complexities are introduced to the cycle. An example of a viable, new, intercooled regenerative cycle is given. A second example of a prototype reheat gas turbine is also included. The overall approach using the heat balance method can be applied to various cogeneration configurations when considering the more complex cycles of the future.

Abstract A hybrid propulsion system of new conception for medium-size passenger cars is described and its preliminary design developed. The system consists of a turbogas set operating at fixed rpm, and a battery-operated electric motor that constitutes the actual “propulsor”. The battery pack is charged by the thermal engine which works in an electronically controlled on/off mode. Though the idea is not entirely new (there are some concept cars with similar characteristics), the present study has important new aspects, in that it bases the sizing of the thermal engine on the foreseen “worst case” vehicle mission (derived from available data on mileage and consumption derived from road tests and standard EEC driving mission cycles) that they can in fact be accomplished, and then proceeds to develop a control strategy that enables the vehicle to perform at its near–peak efficiency over a wide range of possible missions. To increase the driveability of the car, a variable-inlet vane system is provided for the gas turbine. After developing the mission concept, and showing via a thorough set of energy balances (integrated over various mission profiles), a preliminary sizing of the turbogas set is performed. The results of this first part of the development program show that the concept is indeed feasible, and that it has important advantages over both more traditional (Hybrid Vehicles powered by an Internal Combustion Engine) and novel (All-Electric Vehicle) propulsion systems.

In Japan, from the point of view of energy saving and environmental protection, a 300kW Ceramic Gas Turbine (CGT) Research and Development program started in 1988 and is still continuing as a part of “the New Sunshine Project” promoted by the Ministry of International Trade and Industry (MITT). The final target of the program is to achieve 42% thermal efficiency at 1350°C of turbine inlet temperature (TIT) and to keep NOx emissions below present national regulations. Under contract to the New Energy and Industrial Technology Development Organization (NEDO), Kawasaki Heavy Industries, Ltd. (KHI) has been developing the CGT302 with Kyocera Corporation and Sumitomo Precision Products Co., Ltd. By the end of the fiscal year 1996, the CGT302 achieved 37.0% thermal efficiency at 1280°C of TIT. In 1997, TIT reached 1350°C and a durability operation for 20 hours at 1350°C was conducted successfully. Also fairly low NOx was proved at 1300°C of TIT. In January 1998, the CGT302 has achieved 37.4% thermal efficiency at 1250°C TIT. In this paper, we will describe our approaches to the target performance of the CGT302 and current status.
