A large number of polypropylene medical products require special disposal conditions. The most effective and simplest method is combustion. At the same time, it is necessary to minimize harmful emissions that inevitably arise when organizing this process. The paper presents the study results of the combustion rate and combustion completeness depending on the oxidizer supply conditions and the characteristics of the external electric field created in the combustion zone. The possibility of increasing the productivity and combustion plant environmental friendliness has been shown.

The article presents the study results of the solid waste components (on the example of polystyrene) combustion optimizing based on traditional solutions used in the furnaces organization (stratified combustion, combustion in a vortex flow, combustion products recirculation), as well as due to the electrostatic field impact. Relative changes in the CO and NO emissions values were obtained for various methods of air supply to the combustion chamber and electrostatic field parameters. The use of an electrostatic field with a potential difference of 3–4 kV made it possible to increase the combustion efficiency, which led to a decrease in the formation of CO by up to 40%, and NO to almost zero.

Polymers combustion in high-enthalpy flows is realized in many power plants. This process is energetically favorable, but there are also significant problems, the main of which is the low combustion rate. An effective method to increase the condensed component regression rate is the imposition of an electrostatic field on the polymer, the polymer reaction layer, and the combustion zone. The paper proposes a physical and mathematical model of the electrostatic field influence on the PMMA combustion rate in high-enthalpy flows. The combustion rate values calculated within the described model coincide with the experimental results within the error.
