Emerson’s Ovation expert control system will control major equipment and processes at the new Laogang waste-to-energy facility. When the plant becomes operational in June 2013 it will be one of the largest waste-to-energy facilities in China.
Ovation technology to control major equipment and processes at facility that will provide booming Shanghai region with a more desirable alternative to landfilling waste
PITTSBURGH (February 28, 2012) — Emerson Process Management has received a contract from the Shanghai Laogang Refuse Incineration Co. to install its OvationTM expert control system at what will be one of the largest waste-to-energy facilities in China. With a capacity of 3,000 tons of municipal solid waste per day, the facility will provide a more desirable alternative to landfilling waste generated by the area’s burgeoning population and economy. The facility is expected to be operational in June 2013.
Waste-to-energy facilities are becoming more prevalent in developing regions, such as China, because they provide a reliable source of renewable energy while also addressing the challenge of municipal solid waste disposal. There were 70 waste-to-energy plants operating in China as of 2009; more than 100 new plants are in the planning stages, according to Pike Research.[1]
“The new facility will play an important role in supporting this region’s growth, so we wanted to be sure we selected an automation vendor with relevant experience,” said Zhou Xiangyang, chief engineer, Shanghai Laogang Refuse Incineration Co. “In Ovation we found a state-of-the-art control solution that has already been proven in waste-to-energy facilities. This made Emerson the best choice for us.”
At the Laogang facility, Ovation technology will monitor and control the Hitachi Zosen stoker-fired incineration boilers and Qingdao steam turbines (2x30 MW). The Ovation system will also perform data acquisition, as well as manage the plant’s modulating control system, sequence control system, electrical control system, furnace safety supervisory system, turbine DEH/ETS (Digital Electro-hydraulic Control System/Emergency Trip System) and a large number of other balance-of-plant processes and equipment. In all, the Ovation system will be responsible for nearly 7,500 I/O points.
In addition to the Ovation system, Emerson will also supply its EDS enterprise visualization technology, as well as Rosemount 3051 pressure and flow transmitters.
“From biomass and hydro to solar and wind, power generation companies have trusted our technologies for the automation of their renewable energy assets for more than 20 years,” said Bob Yeager, president of Emerson Process Management’s Power & Water Solutions. “With our years of experience automating waste-to-energy plants, Shanghai Laogang Refuse Incineration Co. can be confident that Emerson has the people, tools and technologies in place to help ensure the smooth startup, and safe and efficient operation of its facility.”
