Abstract

As opposed to other fuel combustion appliances, in case of gas stoves, combustion products are released directly into the apartment air. Some people actually spend much time in such environment. Therefore, even low concentrations of harmful substances emitted with combustion products can pose a threat to health and life of people. Maximum allowable concentration of harmful substances in the air was analyzed for various countries. Theoretical calculations of possible content of nitrogen oxides (NOx) in gas-supplied kitchens were performed. Actual NOx content in the air was experimentally studied under various operating conditions of gas stoves and ventilation options. According to the study results, in most of the room, NOx concentration at the height of breathing level of a standing person can exceed the allowable value for premises intended for permanent occupancy.

Highlights

The use of organic fuel is inextricably related to emissions of harmful substances contained in combustion products
If natural/liquefied gas stoves are in good technical state, the list of harmful substances contained in combustion products can be reduced to carbon monoxide and nitrogen oxides
Review of the regulatory framework According to the Polish standard for premises intended for permanent occupancy (Zarządzenie Ministra Zdrowia, 1996), maximum allowable concentrations are established only for 35 harmful substances

Summary

Introduction

The use of organic fuel is inextricably related to emissions of harmful substances contained in combustion products. Combustion products from household gas stoves are released directly into the air of premises. The authors set a task to study the effect of harmful substances emitted with combustion products from gas stoves on the creation of the environment in the kitchen and the entire apartment. If natural/liquefied gas stoves are in good technical state, the list of harmful substances contained in combustion products can be reduced to carbon monoxide and nitrogen oxides.
