Experimental study on influence of combustion bed catalytic thickness on resistance characteristics of fuel-air mixture

摘要

Fuel-air mixture is a typical of flammable and explosive material and tens of thousands of cubic meters of oil steam and air mixture will be presented in the ventilation and replacement project at any time, no matter in the anti-explosion of ventilation operation in the oil tank, or in the anti-explosion of fuel-air mixture in emergency. Thermo-catalytic combusting technology used in the anti-explosion of fuel-air mixture is viewed as a kind of most promising technology, which can safely dispose the fuel-air mixture. This paper mainly introduces the resistance characteristics of fuel-air mixture within the catalytic combustion bed and the experimental results of the influence of catalytic thickness on resistance of fuel-air mixture. Based on the experiment and analysis, the resistance predicting model using in catalytic combusting bed is putting forward. The conclusions drown from the studies and researches will not only have much important significance for the design and optimization with thermo-catalytic reactor for anti-explosion in oil and natural gas engineering, but also supply some important references to the analysis of the fuel-air mixture flowing in porous media in other fields.
