Abstract

Air quality is related to the using of solid fuel based heat sources in which the human factor has a major influence on the quality of combustion, which can lead to higher emissions into the air. One of the negative factors is the use of alternative fuels in heat sources. The article deals with the combustion of various alternative fuels, on a waste basis, in small heat sources. There were tested 4 types of fuels: beech wood pieces, 2 types of solid alternative fuel on the base of municipal waste and wood waste. In the experiment, it was tested the influence of used fuel in the fireplace on the heat output, efficiency, production of gaseous emissions and particulate matter. The results confirmed that combustion of fuels not recommended by the heat source manufacturer reduces the efficiency of combustion and significantly increases all monitored emissions.

Highlights

Small heat sources are mostly used to provide thermal comfort in family houses, especially outside cities [1, 2]
The media are increasingly reporting on the occurrence of smog situations and deteriorating air quality. This is related with the using of heat sources based on solid fuels where the human factor has a major influence on the quality of combustion, which can lead to higher emissions into the air [3, 4]
The highest average heat output of the fireplace insert (Table 1) was as expected during burning the sample 1 - beech wood pieces which are the right fuel according to the manufacturer's recommendation of fireplace insert and reached an average of 13.8 kW

Summary

Introduction

Small heat sources are mostly used to provide thermal comfort in family houses, especially outside cities [1, 2]. In this out-of-town environment, air quality is rapidly deteriorating with the onset of cold weather. The media are increasingly reporting on the occurrence of smog situations and deteriorating air quality This is related with the using of heat sources based on solid fuels where the human factor has a major influence on the quality of combustion, which can lead to higher emissions into the air [3, 4]. Incorrect operation of incomplete combustion heat sources leads to production of enormous emissions
