Intelligent power plant

Bath-based energy group, Blue-NG, has placed an order with MAN Diesel for a series of MAN B&W type 10L35MC-S diesel engines for its Combined Heat and intelligent Power (CHiP) plant.


Bath-based energy group, Blue-NG, has placed an order with MAN Diesel for a series of MAN B&W type 10L35MC-S diesel engines for its Combined Heat and intelligent Power (CHiP) plant.



The CHiP plant being built in London is said to be the first of its kind in the world, with the engines’ high-temperature waste heat driving an organic Rankine cycle (ORC) turbine, and low-temperature waste heat used in a natural-gas pressure-reduction station to drive turbo expanders.



Using the MAN B&W engines, the plant’s total net electrical efficiency is expected to peak at above 80 per cent.


The first four engines will be installed at sites in Beckton and Southall and are intended to supply green, low-CO2 power to London by 2010.



The engines will be built by MAN Diesel’s Polish licensee, H. Cegielski – Poznan.


Each of the two-stroke, low-speed engines generate 6,450kW and have a thermal efficiency of 48.9 per cent.



According to Blue-NG, the high efficiency rating was one of the main reasons it chose MAN B&W engines.


Conventional 6MW diesel engines usually only achieve thermal efficiency in the range of 42-47 per cent.



The first MAN B&W 10L35MC-S engine is scheduled for delivery in December 2009, with the remaining engines following at three-month intervals.
