Heating plant technology now for home use
The Danish company Fumo is putting the automatic control technology of district heating plants into the hands of ordinary householders.
“Our new boilers have two built-in computers that control everything,” says Kim Kristofferssen, demonstrating the control panel on one of the smaller boilers.
Fumo presented its new control system at the World Bioenergy fair in Jönköping, Sweden. The same equipment is used in all boilers from 12 kW to 288 kW.
There were two sources of inspiration for the system. Underneath the cover are functions that only a few years ago were only found in large boiler rooms and heating plants. Two computers measure and control all the parameters that influence the combustion process.
The second inspiration source would appear to be BMW, because menu selection is done by turning a wheel. Kristofferssen agrees that there is a similarity to the solution developed by the German car manufacturer.
“What we tried to do was to create an interface that is as easy to use as the internet,” he says.
The result is that even technical novices can set the system to function optimally and achieve a thermal efficiency level of about 93 percent, as promised by the manufacturer.
The control system also turns the boiler into an “omnivore” that can handle fuel which was previously almost impossible in smaller boilers, such as grain and sawdust. The computers even control the fuel feed system. The result is a flexible heating system that can squeeze every ounce of energy from the fuel.
