Recognising the opportunities of power-to-heat for the future power grid, Munich-based Enerstorage is in the process of developing several industrial sites with installations of electrode boilers. For the first project, Enerstorage has secured support from EEW Energy from Waste (EEW) for building two of Parat’s ten-megawatt boilers at an industrial park in the town of Premnitz. Here, EEW operates a plant to generate environmentally friendly electricity and steam from 250,000t of combustible material. Businesses in the nearby industrial and commercial park are supplied with the generated energy. For the project, Enerstorage provides both financing and expertise in Germany’s market for balancing power.
Parat’s IEH electrode boiler has been designed and developed by the company’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 remote 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 from 7-11 April."
