GENERIC ADVANTAGES AND DISADVANTAGES BETWEEN INDUSTRIAL AND AERO-DERIVATIVE GAS TURBINES

The following describes the generic difference between and advantages and disadvantages between "industrial" and "aeroderivative" gas turbines.

1.0      Introduction

The gas turbines included in this study can be broadly classified into two main groups; that is industrial GTs and aero-derivative GTs. The Trent and LM6QOO are aeroderivatives, all the others are industrial or "heavyweight" units.

The basic difference between these two types of gas turbine is that the aero-derivative units have their hardware derived from aircraft engine technology and the industrial unit was designed for land based use-The aircraft engine requires high thrust at full load, good part load efficiency and low weight. The result is a multi spool design with high rotational speeds and a comparatively high compressor pressure ratio. Normally, industrialising an aero engine involves removing the turbo fan, modifying the LP section to run at 3000 or 3600 rpm and modifying the combustion system.

Industrial gas turbines are designed for land use where size and weight are less important than aeroderivative design.

For electrical generation applications, the industrial machine has a single shaft comprising compressor and power turbine sections. For electrical outputs of nominally less than 50 MWe a gearbox is utilised to reduce the turbine speed to the synchronous sped of the system. Above this size they are designed to operate directly at 50 or 60 Hz without a gearbox.

The main advantages and disadvantages of the two types of gas turbine are given below: -2.0     Advantages of an aero-derivative gas turbine

a.       The aero-derivative units have higher simple cycle efficiencies, which is reflected in the lower exhaust temperature. For simple cycle operation, the lower exhaust temperature is not an issue, however it is an influence for CHP or combined cycle applications. The multi-shaft compressor design also results in relatively higher part load operating efficiencies.

b.       The units have a higher power to weight ratio and therefore utilise less space for the same power output. With lower rotating mass these units take less time to accelerate from zero to full speed no load and with thinner component cross sections the thermal gradients are less and allow the units to be loaded in a shorter time.

c.       The units are designed to a modular concept and therefore carrying out maintenance requires relatively short downtime as worn sections are exchanged for new or refurbished ones.

4.0     Advantages of an industrial gas turbine

a.       The industrial gas turbine vendors are able to offer a greater range of power outputs for any particular project. Also, industrial units are available over a wider power range.

b.       The degradation rates on power output and efficiency are generally lower for industrial units generally due to the positive clearance maintained between the rotating blades and the stators. Aero-derivative compressors utilise wearable seals to improve compressor efficiency but this efficiency degrades more quickly.

c.       All compressor and power turbine maintenance is carried out on sit© with some components returned to the manufacturers works for refurbishment.

d.       With the exception of Siemens, service periods are reduced by a factor of 1.5 when operating on distillate. Siemens advise that their tile arrangement of combustor is not affected in the same way as can-annular types.

e.       There are a greater number of units operating world-wide and although there is continuing development, the industrial units are considered more mature designs.

f.        The higher exhaust temperature of industrial gas turbines allows increased steam production in combined cycle and combined heat and power configurations.
