The Distinctive Changes of Particles' Numeric Concentrations, Are Caused by Electrostatic Flue Gases Cleaning.

A burning processes are always accompanied by emissions, and solid fuel combustion is believed to be the main source of dust releases. Solid fuels are predominant for using by boilers under 300 kW, which are mostly use for heating the domestic buildings and small premises in industrial and other use. It is well known, that using such boilers is inevitably involves the pollution releases, among which are emissions of oxides of carbon, nitrogen and sulfur oxides and particulate matters. After 2020 all boilers in European Union are have to be consistent with the list of ecological norms, and norm ECODESIGN is the one of them. This norm, inter alia, means that PM concentration could not exceed 40 mg/m3N. Such legislative measures are compelling the producers to make steps to decrease boiler´s pollutions. However, it is hard to achieve the desired results by optimization of burning processes only. That´s why arises a need to equip the boilers with the gas cleaning units. Within this context, precipitation particulate matter with electrostatic method is one of the most perspective. Within studies to optimize the constructional and high voltages parameters of ESP, it was appeared unusual phenomenon, which has describing below.\
