Plasma Furnace PP-50M for the treatment of Biomedical Waste

Plasma technology provides an effective and safe alternative for the treatmentl of Toxic Biomedical Waste. The process destroys toxic components (germs, viruses, bacteria, etc.), incinerates organic constituents of waste and compact’s mineral residual.
Plasma furnace PP-50M for treatment of Biomedical Waste has a capacity to process 50 kg/hour of waste. Power used by the system with an after burning chamber is up to 150 кW. The furnace has the following configuration:
  • Loading device for feeding the waste into the furnace
  • Plasma combustion chamber with one plasma torch
  • Afterburning chamber with one plasma torch, to prevent the formation of furans
  • Unloading device for removal the slag from the furnace
  • Electric supply, water supply and gas supply control panel
The furnace can be transported in a standard 40ft container.

How the plasma furnace works

The process of waste incineration is two-pronged. First the waste is incinerated inside the furnace using plasma pyrolysis and then the leftover pyrogas is incinerated in an after-burning chamber, which is especially designed to include all the ecological parameters for effective incineration. It is impossible to achieve the same parameters for incineration in a furnace. Air plasma torches not only effectively pyrolyze waste, but also vitrify its ash slag at a temperature of 1500-1800 Degrees of Celsius. The positioning of the plasma torches is designed in such a way so that plasma stream only comes into direct contact with the molten mass; refractory lining of the inner walls of the furnace remains untouched.

Waste is fed into a furnace through a feeding device. Waste is pyrolyzed at a temperature up to 800 Degrees of Celsius. Furnace gas is partly comprised of volatile products of pyrolysis, and the resulting syngas has a high enough calorific value. The furnace provides an additional air supply and hence makes it possible to regulate this parity, depending on humidity and other physical and chemical properties of the waste.

In afterburning chamber intensive intermixing of gas and air is achieved through cyclonic rotation of streams, and as a result exposure time of gas stream around the chamber is increased. Plasma torch in a afterburning chamber ensures ignition and provides stable burning of pyrogas at a temperature of up to 1200 Degrees of Celsius, even for a rather low calorific value of a pyrogas for this given temperature.

In order to ensure a full incineration, this temperature is complemented with a great surplus of air, as well as a high – power plasma torch.
