UK-based renewable power company, Blue-NG, has ordered two MAN B&W 7K60MC-S engines to power two environmentally friendly power plants in London.
Each sister plant, located in the Southall and Beckton districts, will have one MAN B&W 7K60MC-S engine at its heart, manufactured by MAN Diesel's Polish licensee H Cegielski – Poznan.
Each engine develops 13.9MW at 150rpm and is installed with an organic rankine cycle (ORC) turbine and turbo compound system (TCS) for increased efficiency.
The heat from the two plants will be used in the gas pre-heating process, which is a necessary part of the pressure reduction process for liquid natural gas, and will supply renewable electricity, corresponding to the consumption of up to 100,000 homes.
Blue-NG signed a construction contract with Land & Marine Project Engineering for the design and construction of the power plants in June 2009.
The engines represent the latest generation of the two-stroke, low-speed MAN B&W K60MC-S engine and will run on crude rapeseed oil. In general, the development of this latest generation has targeted lower heat rates and lower carbon dioxide emissions.
The table below illustrates the K60MC-S's performance improvement since its introduction in 1989:
