CNC polishing of compressor blades and vanes to optimize flow efficiency while at the same time minimizing differences due to tolerances in blade geometry. This is essential to the balancing of the compressor rotor and the fit of the stator parts. The SPE allows to keep up with the demand of this for the latest F-Class & H-Class Gas Turbine Compressors. The SPE CNC-Machine allows automatic polishing of all rows of the Gas Turbine Compressor, as well as most rows of Steam Turbine Blades within tight tolerances and highest repeatability. A dedicated CAD/CAM software allows for generation of NC part programs. As the SPE is a cartesian type machine tool there is no need for referencing or time consuming in process gauging. The precision and repeatability of the process allows the balancing of the milling process to leave a rougher scallop on the blade and save valuable time and cutter on the milling side. Capable of polishing compressor blades, fan blades and vanes up to 550 mm in length.

A Steam Conditioning Valve / Combined PRDS Valve is the combination of pressure reduction and temperature reduction of superheated steam to fit process needs, protect downstream equipment or allow the use of less expensive materials or schedules for downstream piping. This is done with a pressure reducing valve and a spray water addition section either as separate units or a single device. Pressure reduction is carried out with a pressure reducing trim within the valve body, usually multi stage pressure reduction. The pressure is controlled by an upstream or downstream pressure controller, signaling the valve to modulate to maintain the pressure at the required set point.Temperature is controlled by adding water to the steam in such away that it will get fully evaporated in the steam, termed as desuperheatmg. These applications are normally considered to be some of the most severe services of any valves in a modem steam plant.

High Pressure Control Valve is designed and developed for applications where the high pressure / drop liquid and high pressure / temperature gas/vapour to be handled. Our specially designed Velocity Control Trim, which is a multi turn / multistage velocity control trim, handles these severe/critical applications very effectively – eliminating cavitation & vibration, and reducing the noise to the acceptable levels.

Turbine bypass valves play a very major role in Power Plant applications. Within a short period of twenty four hours, a power plant may be required to operate at minimum load, increase to maximum capacity for major part of the day, immediately lower back to minimum load and then back to maximum capacity. Bypass System permit unit start up and shutdown in a lifesaving manner for critical heavy components in boiler and turbines. Jet Flow Bypass valves are supplied with hydraulic, electric or pneumatic actuators as per the process requirements alongwith complete control systems as an option.

A Heat Exchanger is a device built for efficient heat transfer from one medium to another, whether the media are separated by a solid wall so that they never mix, or the media are in direct contact.

The needs of the power generation industry include year in and year out reliability, optimum performance for maximum efficiency, and absolute on time delivery to meet plant outage schedules.

Gland seal systems very important to main and auxiliary turbines. Turbine shafts must exit their casings in order to couple up or connect with the unit that the turbines drive (reduction gears, pumps, etc.) The main and auxiliary gland seal systems enable the turbine to be sealed where the shaft exits the casing; in effect keeping "air out and steam in." The purpose of gland seal system is to prevent the leakage of air from the atmosphere into turbine casings and prevent the escape of steam from turbine casings into the atmosphere. The gland sealing system provides low pressure steam to the turbine gland in the final sets of labyrinth packing. This assists the labyrinth packing in sealing the turbine to prevent the entrance of air into the turbine, which would reduce or destroy the vacuum in the associated condenser. Excess pressure (excess gland seal) is removed by the gland seal unloader. Since there are times when steam escapes from the seals, a gland exhaust system is provided.

The Steam Surface condenser is a critical component of both the traditional coal fired power plant and the new generation cogeneration and combined cycle power plants. Main duties of any Surface Condenser are to convert the exhaust steam from its gaseous to its liquid state at certain under atmospheric pressure, and also, to release non condensable presented in the steam cycle, together with vacuum unit. Jet Flow designs and economically sized condenser suitable for smaller turbine ratings under 100 MW. The circular configuration is compact for easy shipping and maintains the level of quality afforded all of our condenser designs. All of Jet Flow’s Surface Condensers are designed and built to the Heat Exchange Institute latest Standards. We also strive to meet all of our client’s project specific requirements.

Water jet ejector uses water as motive force. Liquid Jet Eductors use the kinetic energy of a motive liquid to entrain another liquid,completely mix the two, and then discharge the mixture against a counter pressure and are used in large numbers throughout industry for pumping and mixing operations. Water Jet Eductors consist of three basic components, namely a converging nozzle, a diffuser (or venturi), and a body to hold these parts in their relative positions and to provide a suction (or mixing) chamber. In addition, they can be equipped with accessories such as regulating spindles. Water Jet Eductors can also be staged with higher vacuum steam ejectors. In this case, the eductor serves both as the final pumping stage as well as a fairly good direct contact condenser, condensing the motive steam from the high vacuum steam ejectors.

Jet Flow Steam Jet Ejector and Liquid Ring Pump Combination type Hybrid Ejectors Systems are getting popular in major Chemical, Soap, Food, Edible oil sectors. A typical combination of steam jet ejector system followed by inter-condenser and liquid ring vacuum pump. This type of combination system can achieve vacuum as high as 0.05 Torr. It can be configured as single or multistage ejectors, single or two stage liquid ring vacuum pumps and inter-condenser. It is designed to operate at the same capacities and suction pressures as conventional steam jet ejector systems. Jet Flow Hybrid Ejectors provide a solution for high vacuum operations. They are versatile in handling both wet and dry loads, can be supplied with low level skid mounted packages with instrumentation and with closed loop seal water recycle system for vacuum pumps for the total reduction of effluent. Jet Flow combination type vacuum systems major applications in distillation, evacuation, drying, evaporation, cooling etc.

Large industrial plants often vent significant quantities of low pressure steam to the atmosphere, wasting energy, water, and watertreatment chemicals. Recovery of the latent heat content of lowpressure steam reduces the boiler load, resulting in energy and fuel cost savings. Lowpressure steam's potential uses include driving evaporation and distillation processes, producing hot water, space heating, producing a vacuum, or chilling water. If the steam pressure is too low for the intended application, a steam jet thermocompressor can boost the pressure and temperature to the required level. Operating Principles - Thermocompressors and ejectors operate on the same thermodynamic and physical principle energy contained in high pressure steam can be transferred to a lower pressure vapor or gas to produce a mixed discharge stream of intermediate pressure.

The efficiency of a Steam turbine is mainly determined by the pressure of the steam at its outlet. The Turbine Surface Condenser is therefore maintained under vacuum. To enable this, the Steam Jet Ejector Vacuum System must be capable of removing all non condensable and associated water vapour from the Surface Condenser to produce the minimum steam condensing pressure consistent with physical dimensions and heat transfer and to provide for deaeration of the condensate. The sources of non condensables include air leakage through all system components operating below atmospheric pressure, gases released from feedwater drains and vents admitted to the condenser, gases released for makeup admitted to the condenser, condensate surge tank when utilized in a closed cycle and disassociation of feedwater into oxygen, hydrogen and non condensables.

Based on the process requirement, a Multi Nozzle Ejectors can be designed five or seven nozzles type. Generally, one nozzle in the centre and remaining four or six nozzles are evenly circled around it. Multi Nozzle Ejectors can reduce the steam consumption by 15% to 20% as compared to Single Nozzle Ejectors when designed for the same conditions and it is more efficient to single nozzle ejectors. At times it is also considerably shorter in length when compared with same rated single nozzle ejectors.

Five Stage and Six stage Steam Jet Ejectors with Condenser Five stage and six stage ejectors are designed for absolute pressure in Micron Range. The arrangement of these ejectors is similar to the four stage ejector with additional one or tow non condensing stages. Special Precautions while measuring Low Absolute Pressures : Do not use spring type vacuum Gauges Ensure that the guage tubes are clean and free form contamination Ensure that the guage liquid is clean and free from contamination

Four Stage Ejector with Condenser Four Stage Ejector is having construction and working similar to Single Stage, Two Stage & Three Stage Ejector. When ejector is to be installed at low ambient temperature area, primary booster should be steam jacketed to prevent building up of ice on the diffuser internal bore. Sometimes both primary and secondary boosters are completely jacked to avoid deposition of product inside the ejector. The Four Stage Ejector consists of following components Primary Booster Ejector Secondary Booster Ejector Booster Condenser Vacuum Ejector Inter Condenser Low Vacuum Ejector

Three Stage Ejector is similar in construction as of Single Stage Ejector, but having intermediate condensers. Three Stage Ejector comprises of Booster Ejector, Booster condenser and a Two Stage Ejector. And Two Stage Ejector consists of a high vacuum ejector, a inter condenser and a low vacuum ejector. This system will give higher vacuum and can handles larger quantity of condensable vapors. Gas or Gas vapor mixture is discharged from the first stage into the condenser where the operating steam is condensed and gases are cooled. The cooled gases are then entrained by the second stage and discharged into the second inter condenser. Here, the steam used in the second stage is condensed. The gases are finally entrained by the third stage and discharged to atmosphere.

SingleStage Steam Jet Ejectors are based on the ejectorventuri principle. In operation, steam issuing through an expanding nozzle has its pressure energy converted to velocity energy. A vacuum is created and the high velocity of steam entrains air or gas and the mixture of gas and steam enters the converging end of the venturi, passes through the diffuser where its velocity energy is converted into pressure sufficient to discharge against a predetermined back pressure. Single stage steam jet ejectors are used to create vacuum covering 40 mm Hg. Absolute. Two Stage Ejector with Condenser The system is the assembly of two units whose construction is similar to single stage with inter condenser (direct contact type or surface type). Steam of the first stage is expanded through nozzle entrains the air or other gases and discharges them to diffusers at a higher pressure in the condenser.
