Purpose: The aim of this article is to show the evolution of reaction chambers for solid and gaseous fuels and to propose a new design solution that intensifies the heat exchange process and increases the efficiency of the heating device. Design/methodology/approach: Previous designs of reaction chambers in boiler devices are mainly based on convective heat exchange. New solutions proposed in this work make the heat exchange process mainly through radiation more effective. These solutions have been patented in the Polish Patent Office. Findings: New designs of combustion chambers, in which mainly radiative heat flow is realized, allow for increased power of the boiler device and low emission of pollutants. They eliminate the disadvantages of conventional solutions, which are often burdensome in operation. Research limitations/implications: The new type of reaction chambers based on radiative heat flow will certainly be the subject of energy and emission research, as a result of which it will be possible to carry out a possible correction of the design parameters to optimize the energy conversion process, taking into account different types of fuel burned. Practical implications: The article presents a practical solution for the construction of reaction chambers realizing radiative heat flow between the combustion zone and the heat exchanger walls. The increase in the power of heating devices with their relatively small dimensions and friendly use will stimulate their common use in the municipal economy. Social implications: Correct implementation of the projects included in the article may contribute to the satisfaction of users with improved living conditions, generated savings and contact with modern construction solutions. Originality/value: This paper presents new and patented designs of reaction chambers of boiler devices in which mainly radiative heat exchange is carried out. Keywords: reaction chambers, combustion, gas boilers, coal boilers, heat exchange. Category of the paper: Research paper.
