The LM6000 Gas Turbine was formally introduced at the IGTI Gas Turbine Conference in Brussels in 1990. It was immediately accepted for power generation/cogeneration applications; however, inquiries were received concerning the use of the LM6000 gas turbine for mechanical drive applications. These inquiries included the amount of power available with decreasing gas turbine speed, breakaway torque capability and resonant free operation over a broad speed range. This paper discusses the engineering studies performed to ensure that the LM6000 will be a suitable power source for mechanical drive applications in the 30–40 MW power range.

Gas turbine blade is the key components of generator which using natural gas as the power source. The airflow channel on the gas turbine blade has an important effect on the blade life and the power generation efficiency. Diamond-nickel composite plated grinding needle was usually used for the airflow channel finish. The process of the diamond-nickel composite plated grinding needle was introduced in this paper. Monolayer of the ~60μm diamond was first embedded in 12μm~15μm nickel layer, then followed with 25μm~30μm thicker nickel layer plated to hold the diamond tightly. The results show that, the coating adhesion was affected by the bath pH and the roughness of the needle original surface. The grinding needle manufactured in optimized process was tested with MICROMOT 50/E drill grinder at the speed of 8000rpm, the results showed that, 5-7 holes were drilled on the glass with thickness of 1.5mm; the drilling speed was 1.5mm/min.

Solar’s Mars Model T-14,000 gas turbine was developed and introduced as a 10.5-MW (14,100-hp), 33.5% thermal efficiency, industrial second-generation, simple-cycle gas turbine for mechanical-drive, power generation, and gas compression applications. Options include multi-fuel and rating capability with low emissions. Component development, rig and instrumented engine testing, and extended field evaluations evolved prior to market release in 1991.

This paper presents the Kværner design concept for an LM2500 Gas Turbine Package, with combined engine interfaces for both the LM2500 PE and the LM2500 Plus. The paper also presents the Kværner Modularized Auxiliary System concept, where the lube oil module and the fuel modules are located in separate compartments integrated in the turbine skid, protected from soak-back heat and blade-out conditions.

Significant Effort

Lean-premixed gas turbines are now common devices for low emissions stationary power generation. By creating a homogeneous mixture of fuel and air upstream of the combustion chamber, temperature variations are reduced within the combustor, which reduces emissions of nitrogen oxides. However, by premixing fuel and air, a potentially flammable mixture is established in a part of the engine not designed to contain a flame. If the flame propagates upstream from the combustor (flashback), significant engine damage can result. While significant effort has been put into developing flashback resistant combustors, these combustors are only capable of preventing flashback during steady operation of the engine. Transient events (e.g., auto-ignition within the premixer and pressure spikes during ignition) can trigger flashback that cannot be prevented with even the best combustor design. In these cases, preventing engine damage requires designing premixers that will not allow a flame to be sustained. Experimental studies were conducted to determine under what conditions premixed flames of hydrogen and natural gas can be anchored in a simulated gas turbine premixer. Tests have been conducted at pressures up to 9 atm, temperatures up to 750 K, and freestream velocities between 20 and 100 m/s. Flames were anchored in the wakes of features typical of premixer passageways, including cylinders, steps, and airfoils. The results of this study have been used to develop an engineering tool that predicts under what conditions a flame will anchor, and can be used for development of flame anchoring resistant gas turbine premixers.
