Abstract

The article presents the continuation of the research aimed at designing, manufacturing and selecting the operating parameters of the electrostatic precipitator for household applications. The tests were carried out in the laboratory and real conditions. The object of the research was a pre-production prototype of the electrostatic precipitator installed in the flue gas duct of a single-family building. The source of exhaust gases was a coal-fired, low-temperature water heating boiler with a nominal power of 21 kW (old generation boiler-year of production: 2007). The obtained results showed that the adopted design of the electrostatic precipitator enables the reduction of dust emissions generated in the combustion of solid fuels in households at relatively low operating costs.

Highlights

Significant exceedance of the standards for suspended dust concentrations from low emission sources is a significant problem
Low emission is defined as the emission of combustion products of solid, liquid or gaseous fuels into the atmosphere from sources located at a height not exceeding 40 m
The reduction of dust emissions from the combustion of solid fuels by individual users is possible by replacing obsolete boilers with modern devices that meet emission standards or by equipping existing heating installations with relatively cheap, easy-to-use electrostatic precipitators

Summary

Introduction

Significant exceedance of the standards for suspended dust concentrations from low emission sources is a significant problem. The reduction of dust emissions from the combustion of solid fuels by individual users is possible by replacing obsolete boilers with modern devices that meet emission standards or by equipping existing heating installations with relatively cheap, easy-to-use electrostatic precipitators. Industrial electrostatic precipitators are largesize devices [22] and their design solutions cannot be used to separate dust from low emission sources. An alternative is to place a tubular electrostatic precipitator in the flue gas duct (inside the chimney) [9] Such a design solution was adopted by the authors [16]. The stage of the work was to create a prototype of the electrostatic precipitator It was installed in the chimney channel of a single-family building, heated with the DEFRO Optima 15STD energy boiler with a power of 15 kW and subjected to operational tests
