The possibility of reducing the toxicity of gaseous emissions of power plants by the effect of an electrostatic field on the organic fuel combustion zone
Electric power generation based on combustion of organic fuel is one of the largest sources of air pollution by toxic
substances, including products of incomplete combustion. To reduce the negative impact of power plants on the environment,
various methods are used to optimize the regimes for burning fuel and cleaning the emissions of combustion
products into the atmosphere. One of the promising ways to regulate the combustion of fuels in order to reduce emissions
is the effect of the electrostatic field on the combustion zone. This article presents the results of experimental studies in
which the influence of the electrostatic field on the combustion of various types of gaseous, liquid and solid organic fuels
in various configurations and directions of the electric field was studied. The change in temperature and completeness
of combustion in a diffusion flame can be explained as follows: the electric field causes a shift of active charged particles
to those torch regions where their presence was previously impossible. The field directed along the flow of fuel leads to
a slight increase in the length of the reaction zone, and also causes the displacement of charged particles to the flame
front, where they are oxidized. This leads to a change in the mechanism of chemical reactions, which in turn increases
the temperature and completeness of fuel combustion. The field directed against the flow of fuel reduces the length of the
reaction zone, with the result that the fuel does not have time to react completely. This leads to a decrease in temperature
and combustion. So, it is shown that the influence of the electric field on the combustion zone can both reduce and raise
the temperature of the flame, which can be used to optimize the combustion regimes with the aim of both improving
energy efficiency and reducing the negative impact on the environment.
