Abstract:
In order to realize harmless dipose of toxic propellant useless liquid and gas in aerospace production test site, a rocket kerosene/air combustion dipose device was designed to deal with the useless gas and liquid, and experiments of nitro oxidant or hydrazine dipose by fuel-rich or oxygen-rich high-temperature gas were carried out,respectively.The experimental results show that the combustor operated efficiently and stablely under the two basic working mode, and the gas temperature is less than 1 200 ℃.And the highest concentration of NOx in the emissions is 25 ppm when the mass flow rate of N2O4 in the range of 0～20 g/s, the gas temperature is less than 1 200 ℃ at the same time.When the mass flow rate of methylhydrazine in the range of 0～6 g/s, the VOC concentration in the emissions is <0.05 ppm, and the NOx concentration is less than 2.0 ppm, the temperature of gas increases with the mass flow rate of methylhydrazine continuously, the maximum value is up to 1 300 ℃.Therefore, dipose of toxic propellant by the combustion device is efficient and complete,and exhaust emission meets relevant standards.
