At the “Sikorsky Challenge” startups competition, which has recently been held at Igor Sikorsky KPI, the scientists from the Faculty of Welding presented a mobile plant working on air-water-carbon plasma for coolants heating. They suggested to replace existing combustion types on plasma-based, where air or carbon dioxide acts as a plasma-generating gas, whereas water-coal mixture acts as a reagent.
For realization of this technology, the special equipment is being used. It provides a stable plasma stream initiating from the air in plasmatron, where water-coal mixture is fed. This creates a main plasma torch , where the complete product combustion takes its place. The mobility of the plant is ensured by ultrasonic cavitator, which allows to get the water-coal substance in place, as well as power supply source from the set of small-scale inverter sources based on serial-parallel connection. Mobile plant alows us to derive a thermal power starting from 4 kW to 0.9 MW.
High-potential ways of its application can be:
– heating:enterprises and other public institutions, greenhouses, private houses, boiler houses;
– combustion: waste recycling enterprises, utilization of medical waste, etc;
– thermal processing of metals: cementation of the product, hardening, normalization, tempering, spraying, cutting, welding, melting of metal (enterprises of metallurgical, defense industry).
On the project was working the team of developers from the Department of Surface Engineering, namely: Y.S. Popil, D.V. Stepanov, I.V. Smyrnov, A.V. Chorny, S.P. Solodkyi and, a postgraduate student of Taras Shevchenko KNU, M.V. Klochok. The work has been implemented on the basis of the Faculty of Welding of Igor Sikorsky KPI.
