  • Update on lignite firing - United States Energy Association

    Update on lignite firing 3 Using lignite as a fuel for power generation has several disadvantages. The low heating values and high moisture content of 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

    In order for the boiler to operate stably at the lowest thermal load, which is lower than the current technical minimum of the unit (~55%), it is proposed that pre-dried lignite is also injected into the boiler, as supporting fuel, along with raw lignite, following a co-firing scheme.Author: Panagiotis Drosatos, Nikolaos Nikolopoulos, Emmanuil Karampinis, Panagiotis Grammelis, Emmanuil KakaPublish Year: 2018[PDF]Reduction of fuel consumption and pollutants emissions in : - This paper deals with the possibility of reducing the fuel consumption in a steam boiler supplied with lignite and natural gas by using additives. The analysis is carried out by means of experiments performed with and without injecting a pulverized cerium nitrate additive in the combustion air. The experimental results show that significant reductions of pollutants and fuel consumption have
