Our Turbines

The energy found in the live inlet steam is expanded below atmospheric pressure (vacuum) and is utilized by the condensing turbines. Finally, the steam is vacuum-exhausted from the turbine to the surface condenser, where the exhaust steam’s latent heat is transferred to the cooling water. This is, in turn, returned to the boiler as feedwater and these condensing turbines are straight condensing types.

In addition, the condensing turbine may have bleed points (uncontrolled extractions) to meet steam requirements at medium, intermediate pressures. This provision applies when the bleed (medium pressure) steam volume demand is low, and pressure variations can be tolerated. These condensing turbines are of the bleed cum condensing type.

They are primarily for power generation where bleed steam is required for feed water heating (HP heater, LP heater and Deaerator requirement) and/or where bleed steam is utilized to meet small process demands.

Back pressure turbines are often used in industrial plants and they can be single stage or multistage. It serves as a reducing station between the boiler and the process steam header.

These fall under straight back pressure turbines which can be used when back pressure steam is fully utilized to meet process demands. Here, the resulting power generation is incidental to the process steam demand.

In order to feed the steam demands at medium, intermediate pressures, the back pressure turbine uses bleed points (uncontrolled extractions) when the bleed steam volume demand is low and pressure variations can be tolerated. This makes them ‘bleed cum back pressure turbines’.

Sometimes, the high volume demand along with intolerable pressure variations calls for the use of an extraction steam to meet the process steam demand at intermediate pressure. This is done using back pressure turbines with one controlled extraction point and are called extraction cum back pressure turbines.

They are primarily for power generation where bleed steam is required for feed water heating (HP heater, LP heater and Deaerator requirement) and/or where bleed steam is utilized to meet small process demands.

Extraction cum Back Pressure turbines, which are used in process industries, can be single or multistage. Steam is usually used in several industrial processes at different pressures and temperatures. Also, steam fullfills the power demands of the process

The Turbotech ECT in the extraction cum back pressure variant provides extraction at one or more points at the specific pressure and temperatures required by the process. Apart from serving as a pressure reduction station it may even be used as a driver for drive applications.

The opportunity to control two steam inlets and utilize throttled steam to generate incidental power without impacting the respective processes makes the Extraction cum condensing type turbine one of a kind.

All the process industries can utilise Extraction cum Back Pressure turbines which are designed to meet the specific process steam demand

Traditional Condensing turbines are specifically used for generating power in various industries. Industries that have high-capacity boilers and low steam demands tend to throttle excessive steam. This throttled steam is used to generate incidental power along with meeting the low to intermediate pressure steam demands of the respective process.

The extraction cum condensing turbine provides a combined heat and power generation solution. At the end of the process, the residual steam is further processed in the condenser and sent back to the boiler feed water tank for repetitive use. Additionally, the power generated can be maintained at a relatively steady level despite variations in process steam demands.n point and are called extraction cum back pressure turbines.

They are ideal for industries looking to meet both process demands and power demands from the existing steam sources.
