In October 2023, we invited you to the Green Challenge. The feedback exceeded our expectations and plans. The original plan was to dedicate issue 1/24, which is in front of you, to the Green Challenge. We soon had to realise that we didn‘t have enough space. In addition to articles on the Green Challenge, we also have specialist articles, technical news and news from the industry that we would like to present to you. That‘s why we in the editorial team decided to extend the Green Challenge to the whole year and to publish articles whenever possible. After all, the topics of the Green Challenge will be with us for some time to come.
I would therefore like to continue to ask you, dear readers, to take part in the Green Challenge if you have not already done so. Show us how you will contribute to moving bricks and brick production towards climate neutrality. Keller HCW kicks off this issue with an article on climate-neutral firing. Apart from the Green Challenge, low-emission and efficient production and combustion processes also feature prominently in this issue. In the first technical article (part 1 of 3), Regina Vogt and Marc Homann from IAB Weimar discuss the question of whether hydrogen is suitable as a future fuel gas on the basis of a research project. They look at economic efficiency, combustion properties and the influence of the changed exhaust gas composition on product properties. The other parts will follow in the coming issues.
In the second article, Denny Alex and his co-authors present an experimental study carried out at the Institute for Brick and Tile Research in Essen on the influence of an internal circulation system on the firing of various brick products and the temperature homogenisation of the gas atmosphere.
The brief reports on the first electric tunnel kiln and heat pumps in dryers as well as the review of the programme of the Würzburg Brick and Tile Training Course also impressively substantiate the words of the Managing Director of the Federal Association of the German Brick and Tile Industry about our industry. the brick and tile industry is future-orientated.
I wish you an entertaining and informative read.
