粉煤热解系统的安全设计

Safety design of pulverized coal pyrolysis system

通过对影响粉煤热解系统安全运行的危险因素及危险表现形式所进行的分析,指出煤气、粉尘、氧气、火花、高温、静电、泄漏等,是粉煤热解系统安全设计所应关注的重点危险要素。从系统设计、制造、安装、使用、维护等方面出发,提出了一系列具体的主、被动设计和应对措施,以期能实现工艺系统的安全运行。

Through the analysis of the dangerous factors and forms influencing the safe operation of pulverized coal pyrolysis system,it is pointed out that coal gas,dust,oxygen,spark,high temperature,static electricity and leakage are the key risk factors that should be paid attention to in the system safety design of pulverized coal pyrolysis system.From the aspects of system design,manufacture,installation,use and maintenance,a series of specific active,passive design and solutions are put forward,with a view to realize the safe operation of the process system.
