Process Equipment Steam Turbines Manufacturers – STEAM TURBINES
Ashoka one of the leading Steam Turbines Manufacturers In India, steam turbines are supplied generally for either co-generation of power (electricity) or driving process equipment (such as cane crusher mill, fibrizor, cutters etc. IN case of co-generation of power the turbine in turn drives an alternator (generator).
These turbines can either be used for drive application or power generation application. These turbines are straight-back pressure type and find application where back pressure steam is fully utilized to meet process demands. The power generation is incidental to the process steam demand. The back pressure turbine may also have bleed points (uncontrolled extractions) to satisfy steam demands at intermediate pressures. This provision is applicable when the bleed (medium pressure) steam volume demand is low and pressure variations can be tolerated. These turbines are of bleed cum back pressure type.

Various types of steam turbines, based on operational designs, can be supplied including-
- Back Pressure turbines
- Condensing Turbines
- Single / Multistage Turbines
Back Pressure Turbines
These turbines can either be used for drive application or power generation application. These turbines are straight-back pressure type and find application where back pressure steam is fully utilized to meet process demands. The power generation is incidental to the process steam demand. The back pressure turbine may also have bleed points (uncontrolled extractions) to satisfy steam demands at intermediate pressures.
This provision is applicable when the bleed (medium pressure) steam volume demand is low and pressure variations can be tolerated. These turbines are of bleed cum back pressure type. The back pressure turbine with one controlled extraction point is possible, this extraction steam is also used to meet process steam demand at intermediate pressure when volume demand is high and pressure variations cannot be tolerated. These turbines are of extraction cum back pressure type. Process Equipment Steam Turbines Manufacturers.
Condensing Turbines
A condensing turbine take high pressure steam, expand it in the turbine nozzles and blades, and exhaust it to a condenser at lower than atmospheric pressure. It is principally used when power must be generated with minimum steam consumption. The condensing turbine may also have bleed points (uncontrolled extractions) to satisfy steam demands at medium intermediate pressures.
This provision is applicable when the bleed (medium pressure) steam volume demand is low and pressure variations can be tolerated. These turbines are of bleed cum condensing type. Such turbines find application mainly for power generation where bleed steam is required for feed water heating (HP heater, LP heater and de-aerator requirement) and / or where bleed steam is utilized to meet small process demands.

Single Stage Turbines
Single stage steam turbines are economical and reliable machines which are generally used for smaller power capacities generally up to 2 MW. Various types of frame sizes and design horizontal (axial & radial split) and vertical options are possible depending upon the requirement of the client.
Other design features include overhung and bearings wheel designs, metallic or carbon seals, electronic or hydraulic or mechanical governors, mechanical or electronic safety trip system, direct driven or with integral gear boxes with suitable lubrication systems.
