Rolls-Royce launches new range of medium speed V-engines

21 September 2018

Rolls-Royce has launched a V-line version of its new B33:45 liquid fuel and B36:45 gas engine series in three variants, 12, 16 and 20 cylinder, corresponding to output sizes, 7.2 MW, 9.6 MW and 12 MW. At 600 KW per cylinder the new engines are said to offer a 20 % increase in power compared to their predecessors and are described as a perfect fit for hybrid systems with renewable energy sources. This completes the new engine family from R-R, following the launch of the first variants three years ago. 
“The powergen market is a very important part of our business. Over the last two years we have increased our customer base significantly, both in Asia and the rest of the world. We believe this new power plant platform will be in high demand, especially in the Asian market where many of our customers have access to LNG or natural gas. The B36:45V gas engines are perfect to support variable renewable energy sources in hybrid systems like micro grids”  said Peter Headland, head of Customer Business at Bergen Engines AS, which is part of Rolls-Royce Power Systems.  
The new engines set a new standard in power and efficiency – up to 50% for gas and up to 48% for liquid fuel – with exceptionally low emissions of NOx, CO2, SOx and particulates. 
With a modular design, the B33:45 liquid fuel and B36:45 gas engines will share the same core components. This allows for fuel conversion between gas and liquid fuels with minimal downtime, and will create a very flexible platform. This is especially beneficial in countries with transitioning fuel options. 
The new engine is applicable for different operational modes. This includes baseload, grid balancing, load following and peaking. Waste heat and CO2 can also be efficiently used for industrial processes, district heating, air conditioning, or to drive a combined cycle configuration. 
The B36:45V20 will be the first variant available in the new V-series. The first two engines are planned to be installed as an extension to an existing Rolls-Royce 37 MWe combined heat and power plant in Czech Republic. With the extension, the power plant will, from the end of 2019, deliver 60 MWe electricity in addition to heat for companies and homes in the nearby town.
