Rolls-Royce supplies CHP for 30th greenhouse
Back in 2008 and 2010, Rolls-Royce delivered two combined heat and power plants to the greenhouse operator John Vermeiren in Loenhout and in Merksplas in Belgium. As John Vermeiren says: “The high level of efficiency of the medium-speed gensets and their reliability impressed us so much that we decided once again in favour of Rolls-Royce for the energy supply of our third greenhouse in Meer.”
The gensets are based on the medium-speed B35:40 V12 AG2 engines from Rolls-Royce, each of which is able to generate an electrical output of 5,650 kW and a thermal output of 6,545 kW. They achieve an efficiency level of more than 96 per cent. The electric power is used primarily for the greenhouse lamps and, if required, is fed into the public grid. The greenhouse, which extends over an area of 10.2 hectares, is heated using the heat extracted from the exhaust gas and the engine’s cooling system. The cleaned exhaust gases from the engines are also injected into the greenhouses to increase the level of CO2 and boost plant growth. John Vermeiren expects to achieve an annual production of 7.5 million kilogrammes of tomatoes at the Maxburg greenhouse.
Rolls-Royce has delivered the complete CHP plants, consisting of the power generator sets, the exhaust gas systems, including the SCR systems and the heat exchangers. The electronic control systems are also included in the scope of supply. Operator John Vermeiren and Rolls-Royce have concluded a long-term service agreement for the combined heat and power plants covering approximately 4,500 hours of operation per year over the next 10 years.
