Coal used to be the backbone of industrial process heat and power generation. Today it is still a very important. However, considering the consensus of anthropogenic climate change its use has to decrease in the future.

ERK has designed coal-fired boiler systems for more than 70 years. We therefore have unique experience with the various coal types available. ERK is able to deal well with new challenges by combining decades of design expertise with innovation. Maximising the efficiency of coal-fired boilers is one aspect to lower its impact on the environment. 

Furthermore, ERK has just recently started encouraging the design of multi-fuel boilers that can co-fire other fuels.
