Steam Surface Condenser

When it comes to the performance of a turbine surface condenser in the operational field of a steam turbine cycle, you need utmost reliability and efficiency. Here’s where Jet Flow’s know how is invaluable. We createcustomise package solutions for each particular customer’s needs. Our General Scope of Supply Condenser Circular Condenser having own Flow, Axial flow or side inlet steam entry. Turbine to Condenser steam duct, including necessary expansion joints. Steam Jet Ejector Vacuum System. Flash tank, drain header and Instrument stand pipe. Dump Tube. Condensate Pump system Pumps are in vertical or horizontal arrangement; either API 610, ISO 5199 or standard manufacturer pump design. Control system Including level control valves pressure and temperature indicators, transmitters and controllers. Interconnecting piping with filter, fittings and valves.

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.

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”
