In order to prevent spontaneous combustion, nitrogen gas was pumped in continuously through buried pipes at the windward side of the gob. The nitrogen injection location was 50 m away from the working face and the flow rate could be up to 2000 m 3 /h. However, the air leakage in the caving gob was large and complex and the noticeable …
Replacing air with an inert (non-combustible) gas removes the oxidiser from the system, thereby preventing fire even in extreme heat. The easiest inert gas to obtain is nitrogen since it makes up 78 per cent of our …
Purging is an inerting method commonly used in safety-critical process vessels such as reactors to eliminate oxygen and moisture when operations are started up or shut down. The three primary methods are displacement, dilution and vacuum purging. With displacement purging, an inert gas is injected into an open vessel to displace …
This study investigated the influence of injecting nitrogen (N 2) gas under high pressure into milk protein concentrate (80%, w/w, protein; MPC) prior to spray drying and examining the physical and bulk handling properties of regular (non-agglomerated) and agglomerated powders.MPC powders produced using the N 2 injection (NI) process had …
The inertisation system consists of inertisation headers with nozzles and mounting pads, interconnecting piping, directional valves, temperature sensors, alarms and manual call points.

Inertisation of a gob (goaf) area in a longwall coal mine with nitrogen gas is an effective measure against spontaneous heating of coal. With regards to spontaneous heating indicators (CO concentration and coal temperature) the use of nitrogen inertisation can be applied in three different cases: - preventive inertisation,

When a longwall face approaches the finish-off line, 1 month is normally required to relocate the longwall equipment and seal the longwall panel, during which time the goaf gas atmosphere changes and the risk of spontaneous combustion and gas explosion considerably increases. To minimise the occurrence of these hazards, an …
At a distance of 100 m from the working face, the flue gas with 3%-9% oxygen content injected at a rate of 2000 m 3 /h completely covered the high-temperature residual coal. This caused the maximum temperature ( T max ) to drop from 334.2 K upon nitrogen injection to below 310 K. Additionally, the effect of the oxygen content …
Compared with these goaf inerting techniques, proactive goaf inertisation with inert gas (e.g., nitrogen, carbon dioxide or boiler gas) injected into the goaf area during normal mining cycles has advantages of easy transport, deployment and management, which has been widely applied in Australia to suppress the onset of …

Gases Used for Inerting and Their Selection Criteria. Written by Animesh Chakraborty in Health & Safety, Process. Inerting refers to the process of introducing an inert gas into an enclosed space to release the gas already present, resulting in a kind of hazard. Although this process can be used to displace toxic gases, it is most commonly …

Nitrogen is the most commonly used gas to perform this process, which is known as the "gas removal and refill procedure.". During this process, the levels of oxygen and moisture that are present within an inert glove box are decreased to 1% through displacement and dilution. To accomplish this, a constant flow of inert gas is required.
