How is the rise in oxygen content in the gas producer gas caused?
The role of oxygen in a gas producer is well known, and without the incomplete combustion of carbon and oxygen, our job is to make the oxidation reaction complete, that is, to basically deplete the oxygen in the gasifier.When the material layer is in cold running state, the oxygen content will increase.When the material layer is inclined, striated fire layer, double fire layer, layer chaos, etc., the oxygen content will also increase.During the process of ignition, the material layer is gradually established, the oxygen content is relatively high at the beginning of the layer in the culture furnace, and gradually decreases with time. When the layer in the furnace is cultivated well, the oxygen content reaches the specified standard.Sometimes the furnace body jacket leakage or fire hole steam pipe leakage condensate, also can cause oxygen content rise.
For the rise of oxygen content in the gas producer, we should treat it as follows: keep the temperature and thickness of the fire layer stable;Maintain the stability of the layers in the furnace;Check and judge whether the equipment is leaking in time and make corresponding treatment;Carry out the gas analysis according to the regulations, check the oxygen content in time.
When the two-stage gas furnace is out of production for maintenance, it is a period of high occurrence of safety accidents.Therefore, maintenance must be done in strict accordance with the maintenance safety regulations to avoid the occurrence of all kinds of accidents.
What matters should be paid attention to when gas station of two-section gas generator is in the transportation pipeline for maintenance and repair:
1, when the pipeline maintenance, must be reliable cut off the gas and the internal gas replacement clean.If the gas pipeline is out of service or under maintenance for a long time, the manhole and dispersion pipe must be opened to maintain the natural convection of air in the pipeline.
2. When entering the pipeline, the carbon monoxide content should be less than 24PPM after sampling and analysis.If the content exceeds the standard is prohibited to enter the maintenance work and fire, electricity, gas welding.
3, it is strictly prohibited to carry out maintenance work with gas, not to mention in the running of the gas pipeline to knock on fire.
When working at a height of more than two meters, you must fasten your seat belt.Scaffolding must be strong and reliable and secure with a safety fence.
Security is the lifeline of the enterprise, only to seize security, our enterprise can flourish and prosper.So maintenance personnel must keep in mind these matters, and in strict accordance with the maintenance safety procedures.
