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, When designing eductors experience is all-important to correctly design the nozzle, diffuser, and body and their relative positions as they are all highly critical and vary according to the physical properties of the liquids being handled.

Lub oil reduces friction between moving mechanical parts and also removes heat from the components.
As a result, the oil becomes hot. This heat is removed from the lube oil by a cooler to prevent both breakdown of the oil and damage to the mechanical components it serves.
The lube oil temperature must be maintained within a specific operating band to ensure optimum equipment performance.
Lube oil coolers are designed based on the customer specifications. Designs are available as single coolers or duplex coolers with change over valves.
Duplex coolers can be supplied either in standard Horizontal design or vertical design if space is constrains.

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 make-up admitted to the condenser, condensate surge tank when utilized in a closed cycle and disassociation of feedwater into oxygen, hydrogen and non condensables.

Jet Flow Variable Flow or Multi Nozzle 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. A high turndown of 50 : 1 is standard.

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.
All of the Jet Flow Feed Water Boiler Heaters are designed in accordance with HEI standards, TEMA and ASME codes. Jet Flow uses state-of-the art computer programs to perform the thermalhydraulic and mechanical design of each Feed Water Heater we fabricate.
Jet Flow designs and manufactures both Low Pressure (LP) and High Pressure (HP) feed water heaters which may be installed either vertically or horizontally, depending on the plant design requirements.

Each Jet Flow LP / HP Feed Water Heater will contain from one to three separate heat transfer areas of zones including the Condensing, De-superheating and Sub-cooling zones. Our heaters can be provided with multiple zones within the shell side:

• Condensing Zone : Included in all heaters, steam is condensedin this zone and non-condensable gases are removed.
• Drain Cooling Zone : Reduces temperature of drains leaving the condensing zone to below the saturation temperature. Jet Flow is able to provide both fullflow and partial flow drain cooling zones to meet specific plant requirements. DC zones can be applied in any horizontal or verticle heater as needed to meet plant requirements.
• Desuperheater Zone : Floating design and shielding at the tubesheet minimise thermal stresses. All operating cases are analysed to ensure wet wall conditions are prevented. DSH zones can be applied any horizontal or verticle heater as needed to meet plant requirements.

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.

Jet Flow steam conditioning valve with revolutionary multinozzle atomizer and feed forward design adds to our latest generation of quality valves. The equipment is utilised for simultaneous pressure and temperature reduction of steam. The cooling water is introduced in the highest turbulent zone of the steam. High steam velocity at this point, results in the highest coefficient of heat transfer between the steam and water. The feed forward design assures soft misty spray and instantaneous temperature control over the full range of steam flow.

Jet Flow steam conditioning valves are available in a variety of combinations. These valves are made as per tailor made requirements of customers. The valves are manufactured in angle, Z and globe forms. Spray water entry is from the top through hollow stem as well as from the bottom, depending upon the process parameters.

Vacuum is necessary during various steps of edible / vegetable oil processing. These steps essentially include hydrogenation, fractionation, bleaching, deodorization and de-acidification. 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 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.

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”

Large industrial plants often vent significant quantities of low-pressure steam to the atmosphere, wasting energy, water, and water-treatment chemicals. Recovery of the latent heat content of low-pressure steam reduces the boiler load, resulting in energy and fuel cost savings. Low-pressure 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.

Dump Tubes are an important part of a system discharging in a condenser. These devices are primarily deployed so as to minimize the size of the bypass valve outlet where the specific volume of steam dramatically increases at low or sub-atmospheric pressures.
These dump tubes are normally fitted into the condenser inlet duct and are carefully designed to achieve the final pressure reduction stage and allow the steam to expand and cool prior to entering the turbine exhaust or condenser.
It is recommended to ensure that the Ddump Tube is designed properly with respect to size, shape and profile so as to a void interference with the turbine exhaust steam path under normal turbine operation. The arrangement and the size of the holes in the dump tube are selected so as to minimize noise generation and direct the steam path away from the duct walls and towards the condenser inlet depending upon the installation.
Depending upon the installation, the arrangement of the holes are selected. In case the Dump Tube is installed in the condenser then the arrangement of the holes are drilled in two 90 degree sectors.
This does not allow the steam to go up the turbine exhaust or directly down on to the tubes in the condenser.
In case the dump tube is installed in the turbine exhaust then the holes are drilled around the complete circumference i.e.360 degrees.

 

Operating philosophy:

• The cooling water required to bring down the temperature is sprayed in the valve or in the dump tube. No water is sprayed in the Condenser. The amount of cooling water quantity is calculated by heat balance calculation. Feed forward logarithm is used in the Distribution Control System
• Inlet steam pressure, temperature, and the position of the valve give the low rate of steam via the valve characteristics. The required spray water quantity is calculated as the algorithm has pre-programmed steam tables and is compared via the FT Flow transmitter installed in the spray water line or position feed back transmitter.
• The result is the control signal given to the valve positioner of the spray water valve. The pressure transmitter installed on the dump tube measures the steam pressure in the dump tube. Since the dump tube is a fixed orifice, the signal from the pressure transmitter indicates the flow through the dump tube.
• Since the dump tube is a fixed orifice, the signal from the pressure transmitter indicates the flow through the dump tube.
