LignoPlus: Our fuel solution for industrial customers
LEAG is your strong partner for lignite-based fuel solutions. We are the second largest lignite extractor in Germany and part of the European EPH group.
Lignite is one of the most important energy sources in Europe. It is available long-term in large quantities and is extracted subsidy-free. LEAG operates its own lignite opencast mines in Lusatia in the east of Germany.
LEAG converts around five per cent of the annual mining output into high-quality fuels in its refinery. During the refining process the lignite is dried by combined heat-and-power and moulded to increase calorific value and improve performance properties.
LignoPlus is a fine-grained, industrial fuel with a high heating value. Its liquid-like character ensures an uncomplicated and clean handling. Pulverized lignite is used as a safe and low-cost alternative to heating oil, natural gas and coal in many areas of the economy. LEAG now supplies more than 250 firing plants for its business customers.

Application areas
Boiler combustion system
The firing of pulverized lignite in tank-type boilers and tubular boilers has proven to be an efficient and reliable method of producing hot water, process steam and electricity in municipal and industrial heating plants and combined heat and power plants. Special combustion systems are used for firing.
