lignite

(lĭg`nīt) or

brown coal,

carbonaceous fuel intermediate between coalcoal,
fuel substance of plant origin, largely or almost entirely composed of carbon with varying amounts of mineral matter. Types

There is a complete series of carbonaceous fuels, which differ from each other in the relative amounts of moisture, volatile matter,

soil material consisting of partially decomposed organic matter, found mainly in swamps and bogs in various parts of the northern temperate zone but also in some semitropical and tropical regions.

, brown or yellowish in color and woody in texture. It contains more moisture than coal and tends to dry and crumble when exposed to the air; the flame is long and smoky and the heating power low. The burning of lignite produces more pollution and greenhouse gases than coal. It is found in the United States, Canada, Germany, and elsewhere chiefly in formations formed in the Tertiary period.

Lignite

 

a fossil, slightly carbonized wood of a brown color which has preserved the anatomical structure of the tissues and is externally similar to unaltered wood, as well as the brown coal formed entirely or partly from such wood.

lignite

[′lig‚nīt]
(geology)
Coal of relatively recent origin, intermediate between peat and bituminous coal; often contains patterns from the wood from which it formed. Also known as brown coal; earth coal.

lignite

a brown carbonaceous sedimentary rock with woody texture that consists of accumulated layers of partially decomposed vegetation: used as a fuel. Fixed carbon content: 46--60 per cent; calorific value: 1.28 × 107 to 1.93 × 107 J/kg (5500 to 8300 Btu/lb)

The two new mines in the Ptolemais-Aminteon area will secure lignite supplies for the three new 300MW power plants planned for the region.
The Ptolemais-Aminteon lignite complex is a massive mining undertaking which currently employs 44 BWEs (large and small), 14 stackers, 180 km of belt conveyor installations (accounting for close to 400 km of conveyor belting) and 400 units of auxiliary diesel earth-moving equipment including wheel loaders, hydraulic excavators, trucks, graders and dozers.
24 m/s and the belt life varies from one to ten years depending, primarily, on whether they are carrying lignite or waste, and the abrasiveness of the waste.
The increase in output to 50 Mt/y of lignite will be attained by ensuring that this fleet achieves full capacity.
2~ South Field should have risen to 20Mt/y and it will be one of the very largest single lignite mines in Europe.
