The desire to extract ethane and propane from the natural gas produced by off-shore wells in the Gulf of Mexico, led to the erection of the Cryogenic Gas Processing Plant near Erath, Louisiana. This paper describes the application of a combined cycle (gas/steam turbine) for gas compression and transmission. The installation is none of, if not, the largest and most efficient combined cycles in mechanical drive service, capable of handling over 1200 MMscf/d of gas. The installation incorporates a gas turbine rated 46,800 hp at ISO conditions and a steam turbine rated 29,700 hp. In addition, the cycle incorporates the use of gas turbine variable inlet guide vanes, a supplementary fired waste heat recovery boiler and forced draft fan for independent steam turbine operation.

Prime Movers

Traditionally commercial marine propulsion needs have been met with direct drive reciprocating prime movers. In order to increase efficiency, simplify installation and maintenance accessibility, and increase cargo / passenger capacity; indirect electric drive gas and steam turbine combined cycle prime movers are being introduced to marine propulsion systems. One such application is the Royal Caribbean Cruise Line (RCCL) Millennium Class ship. This commercial vessel has two aero-derivative gas turbine generator sets with a single waste heat recovery steam turbine generator set. Each is controlled by independent microprocessor based digital control systems. This paper addresses only the gas turbine control system architecture and the unique safety and dynamic features that are integrated into the control system for this application.

Part I presented an analysis of the simple and reheat gas turbine cycles and related these cycles to the combined gas turbine Rankine cycle. Part II uses the data developed in Part I and applies the second generation LM5000 to a combined cycle using a steam cycle with 1250 psig 900 FTT (8.62MPa and 482°C) steam conditions; then the reheat gas turbine is combined with a reheat steam turbine with steam conditions of 2400 psig and 1000/1000 FTT (16.55 MPa and 538/538° C). A unique arrangement of the superheater is discussed whereby part of the steam heat load is shifted to the reheat gas turbine to obtain a minimum heat recovery boiler stack temperature and a maximum cycle efficiency. This proposed power plant is projected to have a net cycle efficiency of 50 percent LHV when burning distillate fuel.

Combined-cycle plants are not new. The fuel crunch, however, is relatively new, forcing new economic considerations, evaluations, and designs. This paper presents a UTC modular industrial gas turbine/steam turbine combined cycle which is specifically designed around the new economics, with owning and operating costs the vital parameter, resulting in more efficient combined cycles in the 8000 Btu/kwhr range. Utilizing the modular concept results in a family of combined cycles to fit practically any load requirement.

A cogeneration application of the CW251B10 industrial gas turbine is described in this paper. The gas turbine will generate electrical power and steam from a waste heat recovery boiler located downstream of the turbine exhaust. The steam generated by the boiler will be used to generate additional power in a Westinghouse condensing steam turbine. Steam will be extracted from the steam turbine for use in the plant and for injection into the gas turbine for NOx emission reduction. A description of the plant and components is included. Site performance tests results are presented and compared to the original predicted engine and plant performance.

The paper describes M21 cruise marine combined cycle plant for SLAVA class cruisers (COGAG arrangement). Three guided missile cruisers (Figure 1) are powered by these plants (two plants for each cruiser). During this plant development the more strict demands on weight and size had been taken into account as compared with M25 plants for merchant ships. The paper shows technical data of M21 combined cycle plant, descriptions and design features of SPA MASHPROEKT GT 6004R gas turbine with reversible free power turbine, waste-heat recovery boiler, steam turbine with a condenser and a common gear unit. More than 10 year service experience of these plants is shown in this paper.

The present paper investigates two different solarized combined cycle layout configurations. In the first scheme, a solarized gas turbine is coupled to a solar tower. Pressurized air at the compressor exit is sent to the solar tower receiver before entering the gas turbine (GT) combustor. Here, temperature is increased up to the nominal turbine inlet value through natural gas combustion. In the second combined cycle (CC) layout, solar energy is collected by line focusing parabolic trough collectors and used to produce superheated steam in addition to the one generated in the heat recovery boiler. The goal of the paper is to compare the thermodynamic performance of these concentrating solar power (CSP) technologies when working under realistic operating conditions. Commercial software and in-house computer codes were combined together to predict CSP plant performance both on design and off-design conditions. Plant simulations have shown the beneficial effect of introducing solar energy at high temperature in the Joule–Brayton cycle and the drawback in terms of GT performance penalization due to solarization. Results of yearly simulations on a 1 h basis for the two considered plant configurations are presented and discussed. The main thermodynamic parameters such as temperatures, pressure levels, and air and steam flow rates are reported for two representative days.

Gas Turbine Plant

A type of coupled steam–gas turbine plant is proposed here. It is composed of a regenerative extraction steam turbine and a steam injected gas turbine. Extracted steam of the regenerative extraction steam cycle is not used to heat water through the regenerative feed–water heater as in conventional plant, but injected into a gas turbine to augment the output of the gas turbine, while the exhaust gas of the gas turbine now displaces the extracted steam to heat the feed water of the steam turbine plant. The proposed repowering turbine plant has two merits: the further utilization of extraction steam and the elimination of the complicated waste heat recovery boiler of a conventional steam injected gas turbine plant, in favor of a gas–to–water heat exchanger.

The paper describes the history of design, development and 15 years’ sea-going experience of the MASHPROEKT combined cycle plants. Four R060 type ships powered by eight combined cycle plants each rated at. 25.000 h.p. and three naval ships with six cruise combined cycle plants each rated at. 10, 000 h.p. are in service now. Using of combined cycle permitted to increase their thermal efficiency by 20–30 per cent. To increase efficiency at a speed of 15…18 knots, a special mode of operation is used: the gas turbine and waste heat boiler operate at one board and steam generated by this waste heat boiler is used for a steam turbine of other board. Total operation life of all marine gas turbine units exceeds 330,000 hours.

Combined Cycles

This paper assesses the integration between natural gas-fired combined cycles and grate combustors for municipal solid waste (MSW). Saturated steam generated in the grate combustor is exported to the heat recovery steam generator (HRSG) of the combined cycle, where it is superheated and then fed to a steam turbine serving both the combined cycle and the Waste-to-Energy (WTE) plant. Using a single steam turbine reduces costs and increases efficiency; in addition, superheating steam with the clean combustion products discharged by the gas turbine avoids all penalties (and extra-costs) caused by the corrosive gases generated in the grate combustor, which follow a path and are discharged from a stack completely separated from those of the CC. The optimal CC/WTE plant match is achieved when evaporation is carried out almost exclusively in the grate combustor, with the HRSG bearing the load for superheat (and reheat) and part of feedwater heating. Performance estimates for a combined cycle centered around a medium-size, heavy-duty gas turbine show that WTE/CC integration increases the efficiency of energy recovery from waste by 50% and more, with MSW disposal costs lower by 30–40%. Higher energy conversion efficiencies imply lower environmental impact, notably greater reductions of greenhouse gas emissions.
