This paper presents the results of technological development research to safely and efficiently reduce substances contained in combustion emissions, which may impair the growth of crops and the health of workers, below the permissible limit. There are carbon monoxide and nitrogen oxides. Agricultural crop production factories, including greenhouses and glass greenhouses, may use the combustion emissions of hydrocarbon fuels as a carbon dioxide source to promote photosynthesis. In this study, the upper limit concentration of chemical substances permitted for emissions of the gas-fired water heater was calculated by model calculation, and it was set as the target purification. (1) A system using catalyst and air dilution was constructed, and it was shown that the target purification was satisfied. (2) The constructed combustion emissions purification system was verified under automatic cultivation operation of lettuce for eating raw. It was confirmed that the quality and yield of the fertilization method were equivalent to those of the vaporization type carbon dioxide fertilization method, and that the system exerted its effect stably.
