Pneumatic actuator replacement
TECS have been requested by a customer, a producer of plastics, Latex and Rubber, to upgrade the controls and pneumatic actuator on their Coppus Murray Steam Turbine, which is utilised to drive a compressor.
Turbine Cogen Control Upgrade

Turner ECS has built two control panels for the Fiat Mirafiori car assembly plant in Italy. Each system controls a 27MW steam turbine mechanically coupled to a 40 MW gas turbine driving a generator. The new panels replace the obsolete Woodward 43027 and 501 controllers by MicroNet Plus with a touch screen HMI. The steam turbine’s I/H converters were replaced by Woodward’s CPC-II.


The steam turbine is started using steam of an auxiliary boiler and acts as a starting motor for the gas turbine. As soon as the gas turbine achieves lite-off, the gas turbine control takes over and synchronizes the generator to the grid. Once synchronized, cogeneration is achieved as steam flow to the turbine transfers from the auxiliary boiler to the waste heat boiler and the steam turbine runs under inlet/extraction control.
