As an efficient and clean radiant heating technology, gas catalytic combustion radiant heating has great market potential and application value. Since the outbreak of COVID-19, the importance of emergency technology and equipment research and development have been highlighted after a major event. Therefore, through a series of the analysis of the heating problems of traditional hospitals, the principle of infrared radiation and catalytic combustion, the performance of precious metal catalysts, the design of gas catalytic combustion heaters and the characteristics of energy saving and emission reduction. Meanwhile, with theoretical calculation and experimental development, a kind of infrared radiation heater based on gas catalytic combustion technology was designed and developed. The heater has the following characteristics: The new noble metal catalyst has the characteristics of long life, strong resistance to sulfur poisoning, good thermal stability and high activity;It has the characteristics of instant warmth, high radiation intensity and no irritation to the skin by comparing with the quartz lamp heater which is used commonly in the market. In addition, when the black bulb thermometer was placed at two meters away from gas heater, the temperature difference is only 2.5 ℃ after two hours;In terms of energy conservation and emission reduction, carbon emissions are only 8.78 percent of electric infrared heaters, and emissions of nitrogen oxides and other polluting gases are close to zero. The research conclusions provide technical support and theoretical basis for the research and development of emergency management technology and equipment in infectious wards and mobile cabin hospitals, and expand development direction for the gas catalytic combustion infrared radiation heating technology.
