Gas turbine engines derive their power from burning fuel in a combustion chamber and using the fast flowing combustion gases to drive a turbine in much the same way as the high pressure steam drives a steam turbine. Gas turbine compressors consume a lot of energy in a power generation cycle or mechanical drive. Page 7 of 24 Q612 Gas Turbine Plants 8/21/2019. • Spare Parts Supply and Maintenance for ALSTOM AND HITACHI Heavy Duty Gas Turbines. We briefly discuss about Water tube boiler parts and functions. The compressor section of the gas turbine is predominantly manufactured from ferrous alloys, namely steels and nodular irons. 6 Vertical Pumps for Oil & Gas Discharge Heads The discharge head functions to change the direction of flow from vertical to horizontal and to couple the pump to the system piping in addition to supporting and aligning the driver. The power is defined by typical gauge pressure and temperature values for a turbojet of 20 psi (140 kPa) and 1,000 °F (538 °C). net 3 Figure 2. The rear compressor, or high-pressure compressor, is connected by a hollow shaft to a high-pressure turbine. Cruse, Sankaran Mahadevan, and Robert G. One for heavy-duty gas turbines designed for land-based applications found in large combined cycle power plants. Experience has proven that precision is the key to gas turbine engine longevity. pdf), Text File (. LOOKING FOR DIAGNOSTICS PARAMETERS OF BEARINGS OF THE GAS TURBINE ENGINE LM 2500 ON THE BASIS OF MECHANICAL CONTAMINATIONS IN THE LUBRICATING OIL Summary. Introduction to Gas Turbines for Non-Engineers (Published in the Global Gas Turbine News, Volume 37: 1997, No. Speed-sensing governor; Pressure sensing or load governor; Speed Sensing Governor. Size range. • Gives an insight on the condition of turbine parts, what needs to be checked during an overhaul. It does this using a gaseous working fluid. Performs full range of commissioning, troubleshooting on Gas turbines and associated auxiliary systems within the area of service and new installations projects Perform Fact finding activities on serviced gas turbines different parts Ensure system controls machinery is within plant and machinery design parameters. The major hazards relate to the inventory of flammable gas that can be released if there is an equipment failure. For gas turbines, this is above the ignition speed from where the turbine can acceler-. One of the greatest single factors influencing the construction features of any gas turbine engine is the type of compressor or compressors for which the engine is designed. Gas Turbine Engine Construction and Components (Part B) • Main Components of Gas Turbine Engine • Their functions, main types and differences Gas Turbines. The spear will move backward and forward in axial direction. Gas Turbine Parts.
