Kessels Engineering Works Pvt Ltd

Rajendra Place, Delhi

Kessels has the distinction of being a premier supplier of Steam Turbines complying to and exceeding API-611 standards for general-purpose steam turbines.

Today, Kessels steam turbines are driving various pumps, fans and compressors across Oil Refineries in the Middle east, India and South East Asia that meet the stringent design engineering practices laid out by Oil giants and end customers alike.

Some of the distinguishing features of Kessels API-611 Single Stage Steam Turbines are:

The above features ensure that the customer has complete peace of mind while operating a Kessels API-611 compliant Steam Turbine for their mechanical driving needs.

Back pressure turbines are available in single stage or multi-stage options. Primarily, this kind of turbine is used as a reducing station between boiler unit and the process steam header. Back pressure turbines are commonly employed in industrial plants where a large quantity of steam is required.

Their straight-back pressure nature makes them useful in applications where exhaust steam is fully utilized to meet process demands. The electrical power generated in the process is consumed as per the process steam demand.

Two main applications of a Back Pressure turbine.

1. For drive application- Popularly used in (Sugar mills, Sugar fibrizor, Shredder drive, Pump drives and so on)
2. For power generation application- Used as to generate electricity by powering the generator.

Bleed cum Back-Pressure Steam TurbinesBleed Points or uncontrolled extraction vents in steam turbines enable steam extraction within a medium pressure range. i.e Bleeding Steam is practically possible at low volume steam demands and when there is a high tolerance forpressure variations. Kessels turbines are built on both bleed and back pressure mechanism.

Extraction cum Back-Pressure Steam TurbinesIf there is a need for steam extraction when the process steam demand volume is high and tolerance for pressure variations is minimal, steam turbines with one controlled extraction vent can be very effective. These work under intermediate pressure levels.

Kessels Single Stage Steam Turbines are economical and reliable mechanical drives for Pumps, Fans, Knives, Compressors and Generators. For last 2 decades our engineering staff has worked hard reviewing the customers Consultant requirements and their queries to meet the strict standards of API 611 and 612.Our Single Stage Steam Turbines are available in more than 15 frame sizes and design options to meet steam conditions and application requirements up to 4, 000 HP in single stage configurations.

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.

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.

applications.

Kessels Single Stage Steam Turbine lineup is especially suited for handling of Saturated Steam at low inlet pressures to allow for the pressure drop of the steam to generate power through the turbine via geared or gearless Turbo Generator set solutions.

These Turbo Generator sets can comprise either of Induction Generators or Synchronous Generators depending on the requirement of the customer and their needs.

Kessels Industrial PRV replacement solutions can recover wasted energy by reducing the pressure of the steam through its steam turbines, rather than through a PRV. This would not only generate useful power for industrial use, but also cater to the process steam requirement of the Industry. The end result is drastically reduced operational costs and reduced dependency on the Grid/Other more expensive power sources.

Kessels Single Stage Steam Turbines are designed in such a way that enables the customer to enjoy the complete benefits of a PRV (reducing the steam pressure to what the process demands), while generating useful power, and without compromising on the stability or safety of the system or their setup.

Kessels also offers the option of Multiple valve operated Steam Turbines, which ensure that the customers get the maximum power output, even at partial loads and steam flows. These valves are also available in Kessels Single Stage Steam Turbine range, and can be controlled automatically via the special PLC based governing system Kessels offers for its Turbines that are coupled to Induction Generators
