Electrostatic precipitation as a method to control the emissions of particulate matter from small-scale combustion units

Popis výsledku v původním jazyce

The aim of this study was to investigate the use of an electrostatic precipitator (ESP) for controlling the emissions of particulate matter (PM) from small-scale heating units, specifically boilers that combust solid fuel with a heating power output of &lt;300 kW. The equilibrium between the required precipitation efficiency and the structural parameters of the ESP in combination with the applied voltage were determined. This study presents a method of optimising the applied voltage alongside the specific ESP structural parameters while retaining the required precipitation efficiency. The ESP was designed, optimised, and integrated into a 15-kW boiler without expanding its volume. The theoretically predicted voltages and resulting ESP efficiency (20 kV and 85% respectively) were verified by measuring the reduction in the particle number concentration. The measurements were based on different principles and simultaneously sampled. The PM concentrations were reduced below 40 mg/m3 (0 oC, 101.3 kPa; at reference O2 = 10 %vol.) by nominal and reducing the heat power, which allowed the boiler to meet the requirements of the EU&apos;s Ecodesign Directive. The presented optimisation method can be used in the practical engineering of any type of ESP. (C) 2019 Elsevier Ltd
