Working at a district heating plant.

A very important advantage of the new Euro Therm control system is that its advanced moisture management ensures optimum combustion efficiency. The system measures how well the fuels is used, and continuously adjust the operational parameters based on the wood chips moisture content. The control system adjusts the combustion parameters such as air/fuel ratio – fuel intake etc. This means that we don’t have to regulate and adjust anything manually. It also provides an economic and environmental advantage, in as much as it constantly ensures the most efficient and cleanest possible combustion which again provides cost-efficiency.

Græsted Heating plant doubled its capacity:

To meet growing demand Græsted District heating plant increased its production capacity in 2009 which included a 5.5 MW wood chip boiler that among other things contains new technology for fuel moisture management.

The situation in Græsted was the classic, high production cost coursed by the use of too much fossil fuel-oil during the winter season.

The Board of directors, operating staff and their technical advisors analyzed the future demands and improvements needed to find the optimal solution. The analyzing results outlined the overall approach and a plant specification with tender invitations was distributed to potential suppliers. Price and quality was the overriding parameters, but both concepts are complex because price does not only cover the investment costs, but also sets out expectations of operational economy. It makes no sense to buy an in-expensive system if efficiency is low and maintenance costs are high.

Græsted District heating plant wanted an intelligent technical solution and therefore chose Euro Therm A/S as the supplier.

Plant Manager Svend Manø has played a key role in the design and procurement of the system.

Anlægget måler, hvor godt brændslet udnyttes, og beregner på grundlag heraf træflisens fugtighedsgrad. Herefter indregulerer kedlen selv forbrændingen Det bevirker, at vi undgår løbende at skulle regulere på luftmængden og brændselsindtaget. Samtidig giver det en økonomisk og miljømæssig fordel, fordi man derved konstant sikrer den mest effektive og reneste mulige forbrænding.

Svend Manø is extremely pleased with the equipment where he particularly emphasizes the boiler and stepping grate.

Reliability is top notch, and there are very few alarms. We have only had good experiences with the boiler and the built-in air preheater, and the stepping grate works really well, especially with wet fuel.


satisfied with the bottom line

When the chairman Jens-Erik Hansen compare the investment with the benefits they bring, he is overall very satisfied.

- The selected solution from Euro Therm more than doubled our capacity. We have a future-proof solution that allows to connect the customers in our area that do not have district heating today, while we are at the forefront of future major developments. Our consumers' heating bills were only slightly affected by the project and we have all reason to be very satisfied, says Jens-Erik Hansen.
