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 Boiler Feed Water Heaters are designed in accordance with HEI standards, TEMA and ASME codes. Jet Flow uses state of the art computer programs to perform the thermal hydraulic 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 Feed Water Heater will contain from one to three separate heat transfer areas of zones including the Condensing, Desuperheating and Subcooling zones. 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.

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

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.

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.
