Jet Flow multi orifice desuperheater regulates the amount of injected water by varying the number of orifices during operation. The ensures that the spray water pressure remains constant at all loads and an excellent and almost uniform spray quality is achieved over the full operating range, thereby minimising the tendency of spray water to accumulate in the steam line. Opening of the orifices is regulated by the positioning of a piston operated actuator directly mounted on the desuperheater. This compact and simple design ensures no separate spray water Injection control valve is required.

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.

Vacuum is necessary during various steps of edible / vegetable oil and food processing. These steps essentially include hydrogenation, fractionation, bleaching, deodorization and deacidification. Out of all vacuum equipments, Ejector Vacuum System has established the superiority and versatility of their use as compared to mechanical vacuum pumps. The most outstanding advantage of the Steam Jet Ejector is total absence of moving parts which eliminate mechanical breakdown, and assures constant and dependable operation with freedom from repairs. No adjustment or lubrication is required nor are any specially trained operator necessary as their operation is very simple. Over and above, Steam Jet Ejector Vacuum System convey at very high velocity which are many times the speed of sound, they are capable f handling large volume under vacuum thus making them eminently suitable for deodorization application wherein high quality of open / sparging steam has to be handled.

Jet Flow fixed area nozzle desuperheaters are best suited for applications involving minimal load fluctuations. A fixed nozzle desuperheater utilizes high performance fixed geometry nozzles to reduce the steam temperature by directly injecting water inside the superheated steam flow. The water enters the main desuperheater body, passes through the spray nozzles and discharges into the steam line in the form of a fine mist.

A version of single venturi desuperheater has the same operating conditions. can be mounted easily and quickly in the exisiting pipeline. The unit can be clamped between two flanges. Sizes are between 1 1/2” to 30”

Jet Flow venturi desuperheaters consist of a Laval nozzle which utilises a part of the incoming steam flow to create a reduced pressure zone into which spray water is drawn and atomised by steam energy, and then exits in a short expanding throat which allows pressure recovery. The desuperheating performance remains constant at all loads from 100% or less, because of the atomising steam effect of the steam jet. The design is unique such that the spray water can be supplied at the same pressure as that of the steam pressure. High turndowns are possible depending upon installations

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.

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.

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.

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.

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.

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.

Our heaters can be provided with multiple zones within the shell side Condensing Zone Included in all heaters,steam is condensed in this zone and non condensable gases are removed.

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.

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.

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.

A Variable Flow Erectors are pneumatically / Electrically operated single nozzle ejectors, used to handle the variable suction ad discharge conditions wherein pneumatically / electrically operated needle goes in and out for precise controlling the flow rate based on pressure requirement. It is very useful when a low pressure steam is compressed to a higher pressure level.
