Ignition of a Cold Pulverized Coal Fuel by Means of an Electric Ignition System

Coal-fired generation has long been, and still is, one of the leaders in global electricity generation. The high share coal-fired energy mix is achieved due to known advantages this fuel, including availability reserves, relative ease extraction, ability organise reserves at plants reliable equipment operation even event fuel supply interruptions.  Coal combustion modern industry requires development start-up systems for boiler units without use oil. Fuel oil used starting up boilers maintaining flame during transient or low loads. At same time a number disadvantages, both technical environmental. greatest challenge developing high-frequency ignition understand chemical kinetics processes plasma reaction mixture ignition. This paper presents experimental industrial studies application an electric system coal based on power source. Experimental were carried out laboratory bench with thermal capacity 5 MW. Industrial tests operating enterprises sector Russian Federation. Samples lignite hard different thermal-technical composition. principle impact been proposed.
