Plasma Furnace PP-50A and PP-150A for the treatment
of Sludge and Fly Ash Waste
Plasma Furnace is used for the treatment and disposal of Sludge and Ash Waste. It has a Power level from 100 kW up to 300 kW and a productivity from 50 kg/hour up to 150 kg/hour. The Plasma Furnaces PP-50A and PP-150A are shown in the following figures.
Plasma jet turbulence torch for inclusion in Power Plants and Incinerators
High Temperature Technologies Corp. is developing and integrating gas and steam plasma torches for their use in fuel-combustion installations, such as Power Plant and Incinerator. Their use intensifies the burning process and increases combustion efficiency of fuel. Most importantly, plasma torches significantly reduce the amount of harmful emission thrown into the atmosphere and transform toxic ashes into inert slag.

One of the innovative ways to improve the efficiency of the Power Plant and Incinerator is to supply the furnaces with plasma system stimulation of the fuel combustion. It is based on thermochemical preparation of fuel (TCHPF) in plasma jet turbulence torch; one of the possible versions is presented in Figure 1.
Figure 1. Plasma jet turbulence torch
The main elements of plasma jet-turbulence torch are: plasma arc torch, plasma channel formed by the twyer, as well as tubes for feeding the fuel-air mixture and for feeding the flow of secondary air. The plasma torch is installed on the axis of a special twyer, which is designed for supply of dispersed fuel in the form of fuel-air mixture and for supply of supplementary air into the plasma jet stream. In the twyer is created a plasma flow, which contains a large number of active centers: volatile hydrocarbons, carbon dioxide, hydrogen, carbon residue, water vapor, atomic oxygen, radicals, etc. Interacting with the flow of fuel-air mixture and additional air flow, the plasma torch ignites the air-mixture and causes its effective combustion not only within the twyer, but also further throughout the furnace.
The electric power of plasma torches, that will be necessary for the furnace control and for the adjusting of the furnace regime, lays in the range of 1-3% of the thermal power of the Power Plant or Incinerator.
