Turbine by-pass Description<\/h2>\n

Full range of combined desuperheating and pressure reducing valves, also called steam conditioning stations. One common application of this type of equipment is to by-pass steam turbines.<\/p>\n

Steam turbine by-pass<\/h3>\n

WELLAND & TUXHORN desuperheating and pressure reducing stations.<\/p>\n

Optimum control of steam pressure and temperature; water absorbed throughout the operating range.<\/p>\n

Motive steam desuperheating \/ atomising system. Part of the steam in the valve is exploited for re-injection at jet speed into the nozzles, thus helping to form steam mist and improving its absorption.<\/p>\n

Maximum efficiency at low steam flow (low speeds) with shorter length of the required straight section of piping.<\/p>\n

Custom designs for discharge conditions to the condenser via dump-tube.<\/p>\n

Desuperheating at high and\/or low pressures, output temperature control by calculating the balance of energy (enthalpy) during discharge to condenser.<\/p>\n

In combination with an electrohydraulic system, it meets the DIN EN ISO 4126-5 safety standards for protection against line overpressure, as per TRD 421 TUV-approved system. This design allows for omission of the boiler safety valve given as the valve opens in cases of excessive HP line pressure.<\/p>\n

Noise level guaranteed in accordance with VDMA 24422 regulations.<\/p>\n

Complete hydraulic units and servo systems to control and operate the valves.<\/p>\n

Supply of the complete set of auxiliary valves for regulation or isolation of steam and water injection.<\/p>\n

Integrated solution for the turbine by-pass package: design and supply of equipment, control and legalisation philosophy.<\/p>\n

Technical support for installation, start-up and maintenance.<\/p>\n

Used by several main turbine manufacturers: SIEMENS, GE, ALSTOM, MAN, SKODA, HITACHI, MITSUBISHI, etc.<\/p>\n<\/div><\/div><\/div>
