Abstract
A plasma heater includes a plasma heating section, an exhaust wasteheat heating section, a gas circulation pump, a water cooling system, and a treatment tank for waste gas and waste water. Flames emitted by plasma torches of plasma generators are directly sprayed onto first water pipes for heating. Exhaust generated after combustion of the plasma torches flows through the tail gas residual heat heating section in the metal cylindrical casing, then flows out of the metal cylindrical casing to enter the gas circulation pump, and flows back into the plasma generators through the gas circulation pump for recycling. After the circulating exhaust operates for more than 10 minutes, the discharged waste gas and waste liquid enter the recovering treatment tank.
