Embodiment Construction
[0011] As shown in FIG. 1 , the catalytic combustion device mainly includes a premixing chamber 1 , a uniform-porous support plate 2 and a honeycomb medium-temperature catalytic body 3 . All the gas and all the air pass into the premix chamber 3, and the support plate 2 forms the top wall of the premix chamber 1. The catalyst body 3 is placed on the support plate 2, the support plate 2 can support the weight of the catalyst body 3, and the pores are evenly distributed on the support plate 2, and the catalyst body 3 is provided with a honeycomb airflow channel for the combustion air premix to flow through. The central axes of the gas flow channels of the plate 2 and the catalytic body 3 coincide. The area downstream of the catalytic body 3 along the flow direction of the premixed gas flow is the gas phase space. The catalytic body 5 is a medium-temperature catalytic body, which can be a monolithic catalytic body or a coated catalytic body.
