Transport of flammable and explosive gases
Thread Content
Flammable and explosive gases are compressed by Roethlisberger blowers for transportation. Could an explosion occur if a low-pressure system is connected to the system, or in other words, can Roethlisberger blowers be used for transporting such gases? Are there any relevant standards regarding this?
There are cases of using rotary blowers for gas transportation, which indicates that they can be employed with certain flammable and explosive gases. However, it is recommended to consult the manufacturer regarding their specific application scope to ensure safe use!
It can be used to transport flammable and explosive gases, which is the case in small nitrogen fertilizer plants; however, pressure or oxygen level interlocks must be installed at the inlet to prevent air from entering under negative pressure and causing an explosion.
The interlock settings you mentioned are very necessary – it’s all for safety!
The flow rate of gas is very important; many regulations related to anti-static measures can serve as a reference
Oxygen may be present in the gas mixture, so it seems that using other types of fans is better than relying solely on Roeths fans
In China, rotary vane blowers have been used to transport certain flammable and explosive gases. Structurally, rotary vane blowers cannot be designed with explosion-proof features; this is mainly due to their low cost and specific performance parameters, as few other types of equipment can meet these requirements. Equipment of the centrifugal type can be selected based on one’s own parameters
The setting of oxygen level interlock mentioned on the 3rd floor – how exactly is this interlock implemented? Does interlocking stop the fan?
