| Abstract: | Based on the process characteristics of the wet-feed coal gasification,the fire risks of coal water slurry,pure oxygen with high pressure and crude gas were analyzed,the fire risk factors of the plant house were discussed,and the affected areas of the explosion and jet fire caused by escaped crude gas were calculated.Some methods were advised to prevent fire and explosion in the wet-feed coal gasification plant house on controlling ignition source,preventing forming explosive gas mixture and discovering and handling accidents promptly.The methods of pressure relief and ventilation of enclosed plant house were also discussed. |
