Ecologo-energy aspect of plasma lighting fuel for heat aggregates
Journal Title: Екологічні науки - Year 2018, Vol 20, Issue 1
Abstract
A system for the plasma lighting of low-reaction fuels for heat-generating sets was developed and investigated, when coal used in the boiler can be used as the ignition and accompanying combustion of fuel. In this study brown coal BR-1 was adopted. It is shown that reliable and stable ignition and combustion of coal-water suspension from such coal is carried out at a flow rate of more than 100 kg/hr with a 17,5 kW plasmatron power. The lifetime of electrodes of such a plasma torch is more than 1000 hours. In the plasma coal burner, complete carbon burn-out is achieved with the release of a thermal power of over 290 kW. The plasma system is a low-power compact module that fits into the design of a pulverized coal boiler and allows excluding additional high-reaction fuel - fuel oil or gas.
