Update on lignite firing United States Energy Association

lignite, for example, imply larger boiler size and low energy efficiency when used directly in power plants. The main combustible component of lignite or coal consists largely of carbon and therefore coal/lignite has a higher carbon content per embedded unit of energy than other types of fossil fuels.
