ith a view to ensuring centralised hot water distribution to its customers, LuxEnergie is responsible for the planning, construction and financing of the power plant and where necessary the installation of the distribution network linking the plant to the various consumers. The point at which the heat is transferred to the end customer is the heat transfer station. This station makes do with the bare minimum in terms of space and has a heat meter which measures the quantity of heat delivered and generated by:
Thermal power plant
Heating is produced in boilers using primary energy such as biomass, gas or heating oil.
Combined heat/power cogeneration plant
fuelled by natural gas
Heat and electricity are produced at the same time by means of a combustion engine connected to a generator. The residual heat of the engine is thus used for heating purposes or for cooling using absorption coolers. For its part, the electricity generated is injected into the public grid. If heat demand is higher than the thermal power of the cogeneration modules, one or more backup boilers are brought into use to produce backup heat. This process makes it possible to optimise the use of primary natural resources and minimise the impact on the environment.
via gasification of wood pellets
The wood gasification system operates using DIN EN plus A1 pellets, fuelling a cogeneration engine of thermal power 260 kW and electric power 165 kW. Thanks to the gasification of wood pellets and the combustion of the gas produced by the cogeneration engine, the energy from the raw material is put to optimum use. Electrical efficiency is approximately 30%, and the overall efficiency of the facility is 75%.
This type of installation is suitable both for heating water in swimming pools and heating domestic hot water. It also supports low-temperature heating networks. The solar collectors effectively capture the sun's rays, which then heat the water used to supply production plants for domestic hot water or swimming pools.
Customers are often supplied via a heating network.
Heating is transferred to the end user at a heat transfer station. Hydraulic separation via a heat exchanger separates the network from the customer’s heating system. The transfer station is usually located in the basement and takes up minimum space, leaving the basement free to be used for other purposes.
The meter installed on the transfer station records the amount of heat supplied.
For renovation or modernisation projects, LuxEnergie is also able to deliver a bespoke, fast and reliable solution to supply issues with its portable heating containers.
