Based on three patented innovations (air-assist atomizer, wetness sensor, closed loop PLC), a new low-pressure power GT augmentation system was developed. Two modifications of air-assist atomizer were tested in the Jet Engine Laboratory of the Technion. The tests were performed to investigate influence of thermodynamic parameters on spray characteristics, as droplet size and velocity distribution of the spray. The system as a whole has passed field test in a gas turbine of a power station. Droplet characteristics, conceptual design aspects and tests results are the subject of this paper.

Industrial Gas Turbine

Based on three patented innovations (air-assist atomizer, wetness sensor, and closed loop programmable logic controller (PLC)), a new low-pressure power gas turbine augmentation system was developed. Two modifications of air-assist atomizer were tested in the Jet Engine Laboratory of the Technion. The tests were performed to investigate influence of thermodynamic parameters on spray characteristics, as droplet size and velocity distribution of the spray. The system as a whole has passed field test in a gas turbine of a power station. Droplet characteristics, conceptual design aspects, and test results are described. It was found that the droplet sauter mean diameter was 20μm. The field tests demonstrated that the power augmentation system operates safely and reliably. Wetness sensors and closed loop PLC proved to be a safe method for power augmentation, which prevents droplet penetration into the compressor inlet.

The paper describes the modifications required to make the GT35 industrial gas turbine suitable for use in fast ferries as propulsion machinery. The modifications made to get the unit to meet pitch and roll requirements are dealt with, as well as the engine support system modifications. The GT35’s capability to burn low quality, liquid fuels is discussed, and a close look is taken at the effect such fuel has on the life of the unit and the time between service. In order to facilitate power production on the ship, the GT35 has been equipped with a starting motor which during operation is used as a shaft driven generator. The generator is driven by the low pressure rotor. Each generator can produce 500 kW, which means 1000 kW for the ferry. The effect of the arrangement on the rotor system behavior is described. At the time of writing this paper ABB has sold 6 GT35 units for operation in 3 fast ferries. The speed of the ferries varies between 40 knots and 60 knots. At the time of writing this paper, the first of the two HSS 900 ferries for Stena Line, Sweden, has just completed its first set of sea trials.

The lean, premixed H combustion system was targeted to deliver low NOx and CO emissions from 50% to 100% combined cycle load in both the Frame 7H (60 Hz) and Frame 9H (50 Hz) heavy-duty industrial gas turbines. The H System™ is the first gas turbine combined-cycle technology capable of achieving 60% thermal efficiency. The present paper describes field test performance of the combustion system during the launch and operation of the initial MS9001H installation at Baglan Bay power station near Port Talbot, Wales. The 480 MW 9H combined cycle, fired using the 14-chamber DLN2.5H combustion system, was comprehensively evaluated during the gas turbine Characterization Test program over a period of several months in late 2002 and 2003. Results are reported for exhaust emissions, combustor component durability, operability, and other key combustion system performance parameters over the full gas turbine operating range. The present paper also describes the operability of the H combustion system throughout a rigorous validation of the power plant system, including National Grid Council testing, load rejections, and other key system transients.

RF inductor power losses of ferrite-free electrode-less low pressure mercury inductively-coupled discharges excited in closed-loop dielectric tube were studied. The modelling was made within the framework of low pressure inductive discharge transformer model for discharge lamps with tubes of 16, 25 and 38 mm inner diam. filled with the mixture of mercury vapour (7.5×10–3 mm Hg) and argon (0.1, 0.3 and 1.0 mm Hg) at RF frequencies of 1, 7; 3.4 and 5.1 MHz and plasma power of (25–500) W. Discharges were excited with the help of the induction coil of 3, 4 and 6 turns placed along the inner perimeter of the closed-loop tube. It was found that the dependence of coil power losses, Pcoil, on the discharge plasma power, Ppl, had the minimum while Pcoil decreased with RF frequency, tube diameter and coil number of turns. The modelling results were found in good qualitative agreement with the experimental data; quantitative discrepancies are believed to be due skin-effect and RF electric field radial inhomogeneity that were not included in discharge modelling.
