ThyssenKrupp: Energy Efficient Boiler for Process Steam Generation
First reference unit of climate protection project "JIM.NRW" in Gelsenkirchen
ThyssenKrupp Electrical Steel based in Gelsenkirchen is a global player, producing grain-oriented electric strip. This is needed for the production of energy efficient transformers and high performance generators. The material contributes to minimize losses with energy transmission and distribution.
In 2008 four boilers for the generation of process steam were replaced by only one new steam boiler. The old construction, built from 1989 to 1993, had a steam output of eight tonnes per hour. The output of the new boiler was reduced to seven tonnes per hour. It is equipped with an "Economizer", a continous burner with O2-control, to improve its energy efficiency. The Economizer upgrades the waste heat recovery and the continous burner with its O2-control improves the combustion process. All in all, the new boiler boosts the efficiency by ten per cent and reduces CO2-emissions by some 510 tonnes a year.
ThyssenKrupp was the first company that participated in "JIM.NRW". This project is to raise awareness of climate protection with companies and local authorities. JIM.NRW addresses NRW based plant operators who can clearly decrease their CO2-emissions. This can be achieved though new efficient boilers that reduce energy consumption or that works with a low-emission fuel. Both industrial plants and office buildings and larger housing estates can be included. The members of the project feed their reductions of emissions in the project. In doing so they earn tradable emission rights.
EnergieAgentur.NRW runs the projects by order of the Ministry of Economic Affairs and Energy NRW. JIM.NRW bundles lots of activities of energy efficiency and thereby makes them attractive for commercialization. EnergieAgentur.NRW transforms the achieved reductions of CO2-emissions into emission rights and sells them in the market. The earned profit is prorated to all participating companies. Further, EnergieAgentur.NRW takes the monitoring (check of the implemented CO2 saving) and involes international partners in the project.
Due to emission trading, energy efficiency and CO2-reduction directly pays off for the members of the project. For TyssenKrupp, a price of 15 euro per tonne means additional revenues of 7,650 euro a year. This means 34,500 euro till 2012 when the project officially ends.
