Germany has been the largest lignite producer in the world since the beginning of industrial lignite mining. It still is, followed by China, Russia, and the United States. The softer and moister lignite (also called brown or soft coal) has a lower calorific value than hard coal and can only be mined in opencast operations. When burned, it is more CO2 intensive than hard coal.

This is the largest cohesive lignite seam in Europe, and RWE Power extracts around 100 million tonnes every year. Found close to the surface, the fuel is dug out of the Garzweiler, Hambach and Inden mines by enormous diggers, including the largest of its kind in the world, which once played starring role in a TV documentary by the Disney Channel.

The main goal of coal quality control in lignite mines is to supply coal to power plants within certain quality constraints. Coal properties can affect the efficiency, reliability, and availability of both the boiler and the emission control units. This paper presents a new based integrated mine process simulation approach to in-

Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. Lignite has a low heating value and a high moisture content and is mainly used in electricity generation. The precursor to coal is peat. Peat is a soft, organic material consisting of partly decayed plant and mineral matter.

Modern methods referred to as 'artificial intelligence' have been applied to combustion optimization and implementation of selected diagnostic functions for the milling system of a pulverized lignite-fired boiler. The results of combustion optimization have shown significant improvement of efficiency and reduction of NO, emission.

R Keith Mobley, in Plant Engineer's Handbook, 2001. Lignite. Lignites are brown and have a laminar structure in which the remnants of woody fibers may be quite apparent.
