Pilot-Scale Experiences on a Plasma Ignition System for Pulverized Fuels

The need for flexible power generation is growing worldwide as the energy transition altering operational regimes of thermal plants. Plasma ignition systems, an alternative technology to conventional start-up method with natural gas or oil firing, offer a cost- and energy-efficient process in pulverized fuel stations. application plasma systems cold start-ups using different qualities pre-dried lignite investigated pilot-scale combustion facility. A integrated swirl burner developed validated highly ignitable dust. Eight moisture content up 30% broad particle size distribution are this determine applicability limitations system regard quality. performance lignites categorized based on their performance. All were ignited under cold-start-up condition 4 kW 7 kW. Lignite 20% median below 450 ?m form self-sustained flame short-time plasma-supported combustion, while blow-out observed lower qualities.
