How to improve the performance of lignite power plants?
It is possible for modern high efficiency low emission (HELE) lignite power plants to approach the performance of hard coal electricity stations (40%+). But much of this low cost power generation uses raw lignite feed and subcritical steam boiler technology. This means the average efficiency of the lignite fleet is only about 28% and there are ...

What are the types of coal? | U.S. Geological Survey
There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, …
