Control system order signed for waste incineration

Yokogawa is supplying distributed control systems to five incinerators in the northern Italian region of Emilia Romagna.

Yokogawa Italia has won an order worth more than Eur 5 million to supply Centum CS3000 distributed control systems to Hera (Holding Energia Risorse Ambiente) of Bologna.

The systems, which will be installed during 2007 as the plants come on stream, will be used for the control of five waste incinerator plants in the northern Italian region of Emilia Romagna.

The new waste incinerators have been designed by Hera's Ingegneria Grandi Impianti division to achieve clean, efficient and environmentally friendly waste disposal with the optimum utilisation of electrical and thermal energy.

The Yokogawa equipment is being supplied on a 'turn-key' basis, and the contract includes, in addition to the main control system, the fieldbus- based communications and networking, field services, audio IP and CCTV systems and maintenance services over a six-year period.

In addition, because of the synergy with the control system, Yokogawa Italia will also supply all the field instrumentation for the plants.

The project includes around 1000 transmitters, 50 flowmeters, and 30 analysers over the five plants.

The control systems are based on the Centum CS3000 DCS, of which roughly 18,000 systems have been installed worldwide, to carry out the management, automation, supervision the control of the plant, including all equipment and subsystems for the ovens, boilers, steam turbines and smoke purification systems.

The field communication system chosen by Hera is based on modern fieldbus technologies including Foundation Fieldbus and Profibus DP.

Each system in the main plant will acquire data from 7700 physical points (including the field bus) and about 5500 other serial inputs from various subsystems.

In the other plants, the corresponding values are 4500 physical points and 4000 serial inputs.
