In case of impulse steam turbine

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.

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… WebIn most cases, the hydrogen-fueled engines show lower specific fuel consumption, lower turbine entry temperature, and less NOx emissions compared with conventional engines.
