First 8-cylinder Bergen B36:45 gas engine goes to Belgium
By Jack Burke18 January 2021
Tomw@tt one of first customers with 6-cylinder variant as well
A Belgian tomato producer will be the first customer to install the 8-cylinder variant of the Rolls-Royce Bergen B36:45 engine series.
The order by Tomw@tt comes after being one of the first customers of the 6-cylinder variant of the Bergen B36:45 gas engine in 2018. The medium-speed genset is planned for delivery in the spring of 2021 and will replace an existing Rolls-Royce Bergen 12-cylinder B35:40 genset.
Compared to its predecessor, the new B36:45 engine offers a 20% increase in power per cylinder and offers lower fuel consumption and emissions.
The new plant will generate 4700 kW electrical power and 5520 kW heat. Tomw@tt plans to use the generated electricity to power the greenhouse led lighting and sell the surplus energy to the Belgian grid. Heat extracted from exhaust gases and engine cooling systems will be used to heat up the greenhouse facility. In addition, cleaned CO2 from the engine exhaust gases will be injected into the greenhouse to increase the level of CO2 and boost plant growth. Due to the release of condensation energy in the exhaust gas, the plant will achieve outstanding efficiency levels.
Rolls-Royce has supplied the complete CHP for the greenhouse, including the exhaust gas systems with a selective catalytic reduction (SCR) system, heat exchangers and the electronic control system. Most of the current plant equipment will be re-used or reconditioned, in addition to new equipment as required for the new 8-cylinder engine.
