AS:SCAN has received its largest electrical-boiler order to date, with a Danish customer requesting two 40MW Parat Halvorsen high-voltage electrode hot water boilers.
The sale is a collaboration between AS:SCAN and Tjæreborg Industry, and the boilers will act as peak units and back-up units, but could be part of the network-regulating market in the long term.
There are high demands for reliability, which make the project more challenging than usual, but AS:SCAN and Tjæreborg are using this as a positive, as many competitors drop out early in the process.
Parat’s IEH electrode boiler has been designed and developed by Parat Halvorsen’s in-house engineers and manufactured in its workshop in Norway for more than 20 years, to a compact design of up to 50MW in one unit. It allows users to switch from cold to full load in less than 15 minutes, with 30 seconds from minimum to full load. Minimum load is below 2%. Significantly, there is no current to earth, no electrode wear and the boiler requires only minimum maintenance.
Power from wind and solar energy can be used in the boiler for steam or hot water purposes. Hot water can be stored during peak production periods, and used when needed in district heating.
Parat’s remote monitoring system enables web-based monitoring of the boiler plant from anywhere in the world. This also includes online troubleshooting and upgrades of the control software from the Parat Halvorsen AS service centre in Norway. Another significant feature is that the electrode-boiler system can be delivered in a complete turnkey boiler house.
Parat Halvorsen sales director Martin Løvland said: "We made a major breakthrough after participating for the first time at Hannover Messe as an exhibitor last year.
"It was a particularly busy exhibition, the world’s leading event for industrial technology, and it gave us the opportunity to demonstrate how our system generates heat from renewable sources.
"We will be exhibiting again with a full scale electrode boiler at this year’s Hannover Messe 7-11 April."
