Low Sulfur

An Internally fired semi-closed cycle gas turbine for Naval propulsion was designed and built for the U.S. Navy by the Westinghouse Electric Corporation. Due to a revision of the overall Navy propulsion program the plant was not tested at design conditions or mode of operation, but feasibility information for this configuration of gas turbine plant was obtained. Plant tests indicated that this cycle configuration can be expected to attain a significant reduction in shipboard space and weight requirements while matching existing conventional propulsion plant fuel and air consumption rates over a wide load range. The plant further is simply controlled to minimize manning personnel, permit bridge control, and has a brief transient period from cruise power to full load. Plants of this cycle configuration can be expected to produce large powers such as required for main ship propulsion while employing components of the size where considerable industrial experience has been accumulated. Fouling and corrosion of the internally fired, semi-closed cycle gas turbine were evaluated by the tests. Conventional gas turbine components are satisfactory for low sulfur fuel operation, and with additional precooler equipment development it is expected that high sulfur fuel operation will be achieved.

New Generation

To produce a new generation of gas-pumping units and to upgrade the existing ones, the producer needs to update their heat exchange equipment. The aim of the update is to decrease its mass and sizes and to reduce its manufacturing and assembly costs. Heat-hydraulic calculations and experiments with models of the gas-turbine plant cassette-tube airheaters demonstrated that application of profiled U-tubes of a small hydraulic diameter to manufacture the matrices of such heat exchangers provides a high compactness and low metal consumption rate typical for plate heat exchangers. Simplicaty, reliability, elasticity and maintainability which are typical characteristics of tube heat exchangers are retaned.

Measurement and prediction of damage to gas turbine aerofoils is of interest to both gas turbine plant operators and suppliers. Metrology methods have been developed to produce accurate and statistically significant measurements of the extent of metal damage after a period of plant operation and to give confidence in results obtained, especially from relatively short term tests. These methods of assessing materials/component performance are based on the use of contact metrology prior to exposure and optically guided measurement around precision prepared cross-sections after exposure. These methods can be used to make several hundred measurements of component dimensions after which the statistical analysis of the data can be carried out for assessment of materials performance. Such measurement methods can be applied to other components in power generating systems, eg heat exchangers.

This is the second report of a program dealing with the transient response of heat exchangers [1a], [1b]. Analog solutions are used to supplement some analytical solutions so as to provide fairly complete coverage for the heat exchangers encountered in gas-turbine plants. Because a gas flow exists on at least one side of the heat-transfer surface, these exchangers are characterized by a large wall-capacitance effect. Where greater generality is possible, the extension to other heat exchangers is indicated.

Special Case

Solutions are provided in nondimensional graphical form for the transient response of the outlet fluid temperatures of a counterflow gas turbine regenerator arising from a step input change of one (either one) of the inlet fluid temperatures. Both direct-transfer and periodic-flow regenerators are considered. The periodic-flow regenerator solutions are derived as a generalized result from a limited number of computer solutions for special cases. The direct-transfer regenerator solutions are derived as a generalized result from a limited number of special case solutions obtained from an electromechanical analog. This report is a continuation and extension of previous work covered in [1, 2, 3, and 4].

Calculations made prior to building the Oberhausen closed-cycle gas-turbine plant have been fully confirmed after nine years of operation. Operating experiences reviewed are (a) with the air heater, including radiation parts, convection part, brickwork, and double-jacket pipe; (b) with the machine set, including LP and HP compressors, turbine, and gearing; (c) with the heat-exchanging units, including heat exchanger, precooler, and intercoolers; (d) deceleration and acceleration of the machine to/from cold state. Breakdowns and failures referred to were of the sort that can be avoided both safely and cheaply by applying the experience we have now accumulated.

Exchange Matrix

The aim of this work is to determine the effect of the elements, which do not participate in heat transfer, on the mass of the regenerator of a gas turbine plant X, as well as to define the re-strictions that are imposed on the regenerator design based on the conditions of manufacturabil-ity, placement at the facility and transportability. This goal is achieved using an algorithm for finding rational geometric parameters of the heat exchange matrix with minimization of the re-generator mass by Newton's method. It has been determined that the mass of the heat exchange matrix can be 0.48–0.58 of the mass of the regenerator. This makes it necessary, even at the initial design stages, to take into account the effect of the above factors on the mass of the re-generator and the choice of the rational geometrical parameters. A significant result of the stud-ies performed is determination of the effect of dimensional restrictions and requirements for the shape of the regenerator to be increased in its mass. The values of the geometrical parameters of the heat exchange matrix were obtained, at which the mass of the regenerator takes on a mini-mum value. The significance of the work is that the obtained relationships between the mass of the regenerator and its geometry makes it possible to reduce the metal consumption of the regen-erator and the gas turbine plant, which allows designing the heat exchangers for power plants
