At Zander & Ingeström’s headquarters in Täby, north of Stockholm, we have twenty-five employees. Around the world, our partners and affiliates employ an additional twenty-five.
Though globally dispersed, we form a closely-knit group that has worked together for many years developing know-how, experience and a great loyalty to our customers – and thus also to our own business. No one could wish for a better foundation to build on for the future.
THE ART OF DESIGNING AND MANUFACTURING, SUPPLYING AND INSTALLING A BOILER SYSTEM
The heart of the boiler systems that Zander & Ingeström deliver is our pressure vessels and control systems. Everything is manufactured in house and all designs are approved by an accredited independent inspection authority.
Commission: We were asked to reinforce the boiler house at Hallsta Paper Mill, where we previously supplied a 40 MW boiler. The new boiler has a capacity of 60 MW and a design pressure of 32 bar, making it the largest in Sweden.
Hallsta Paper Mill is one of our oldest customers. In 1917, our company’s founder, Bengt Ingeström, supplied Hallsta with a steam accumulator.
In Norway we have supplied a large number of plants over the years. Below are three of our most recent projects.
Vika Värmecentral, Oslo – 40 MW
Glomfjord – 2 x 7 MW Ånga
Grane Oilfield – 28 MW Ånga
Commission: Germany has a long history of installing plants that generate renewable electricity using wind and sun. To take care of the surplus electricity that naturally occurs in these facilities, our boilers are installed. They convert the surplus electricity to heat/steam that can then be distributed into the district heating network or to an industrial business.
Keljonlahti CHP 10 MW auxiliary steam generating system
Wärtsilä: 2 x 25 MW Hetvatten
Olkiluoto 3: 2 x 15 MW Ånga
In Denmark, we have made a large number of deliveries where our boilers are part of the energy system.
Locally there are large surplus of electricity and boilers used to take care of this electricity and recycle energy for district heating networks.
All installations are performed by our partner Averhoff Energi Anlaeg A/S.
Commission: In 2013, we delivered four different plants to China. These boilers utilize low electricity rates at night and temporary surplus of electricity from wind power.
The largest plant in Rizhao consists of four 40 MW boilers, making it the world’s largest electric boiler plant. The entire delivery included 11 boilers, with a total output of 250 MW.
Furthermore, we deliver auxiliary steam boilers to four Chinese nuclear power plants in Haiyang, Changjiang, Rongchen and Lufeng.
