The extraction condensing turbines are used when a constant pressure steam flow has to be extracted for process purposes. The constructional characteristics of these turbines are very similar to condensing turbines from the second admission valve chest it is possible to inject low pressure steam, available in the plant to supply the power required by the plant. these turbines are typically used for co-generation where the turbine meets both the power and steam demand of the process plant. In these type of turbines the power generated can be maintained more or less at a steady level despite variation in process steam demands. In some cases it may be necessary to have both bleed and controlled extraction steams from the condensing turbine. These turbines are of bleed cum extraction condensing type.

We offer ctmi steam turbines single-stage steam turbines have been a fixture in most process industries for nearly a decade, providing clients with economical and reliable mechanical drives for pumps, fans, knives, compressors and generators. For many years our engineering staff has worked with consultants to meet the strict standards of api 611 and 612. kessels steam turbines sales offices representatives located around the world, are staffed with experienced professionals to help you select the right steam turbine from more than 15 frame sizes and design options to meet your steam conditions and application requirements up to 4, 000 hp in single stage configurations. 100 hp (75 kw) to 4, 000 hp (3000kw)up to 17, 000 rpm pressures to 65 kg cm2 925 psig, temperatures to 460c 860f.

We are offering condensing turbines. The condensing turbines take high pressure steam, expand it in 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. these type of turbines find application mainly 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.

Steam turbines directly coupled to generators range from 20 to 30 mw .the steam turbines can be packaged with most of the auxiliaries to ease plant design and installation problem. This line of turbines has many applications for the use of extraction and admission process steam, employing several combinations of internal and external control valves. Using these valves provides ctmis customers with process flexibility and excellent partial-load efficiency when the turbine is used to supply process steam. directly coupled steam turbines in combined cycle applications must provide the performance and flexibility required for integration with gas turbines and heat recovery boilers. Packaged arrangements, when feasible, offer shorter delivery and installation time. power up to 30, 000kwsingle end driveinlet steam pressure 105 atainlet temperature range 540 deg c.

We offer back pressure turbines can either be single stage or multi-stage which are often used in industrial plants, the turbine serves as a reducing station between boiler and the process steam header. these turbines can either be used for drive application (sugar mill drives, sugar fibrizor shredder drive, pump drives and so on) or power generation application in which case the turbine drives the generator. 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.
