The velocity compounded Impulse turbine was first proposed by C.G. Curtis to solve the problem of single stage Impulse turbine for use of high pressure and temperature steam. The rings of moving blades are separated by rings of fixed blades. The moving blades are keyed to the turbine shaft and the fixed blades are fixed to the casing. The high pressure steam coming from the boiler is expanded in the nozzle first. The Nozzle converts the pressure energy of the st… WebSteam turbines were traditionally more impulse but continue to move towards reaction designs similar to those used in gas turbines. At low pressure the operating fluid medium …

"WebTurbines are designed with multiple stages to accommodate the volume expansion of steam as the pressure drops. As steam moves through the system and loses pressure and thermal energy, it expands in volume, requiring a larger diameter and longer blades in each succeeding stage to extract the remaining energy.

WebApr 4, 2024 · Heat is transferred to water in the boiler from an external source to raise steam. The high pressure, high temperature steam leaving the boiler expands in a turbine to produce shaft work. Steam leaving the turbine condenses into water in the condensor i.e. rejecting heat. Then again water is pumped back to boiler with aid of pump.

WebIn the impulse-type steam turbine, the steam expands in the nozzle and its pressure doesn’t change as it moves over the blades. In the reaction type, the steam expands continuously as it passes over the blades and thus there is a gradual fall in pressure during expansion.
