Can process waste gas be discharged through the boiler chimney?
Thread Content
May I ask: Can the carbon dioxide waste gas generated from desulfurization and decarbonization in the coal gasification unit be released through the boiler flue?
Chimneys with online monitoring are not allowed, as it will affect the monitoring values; those without online monitoring are acceptable, provided that the chimney’s emission capacity is sufficient.
**Are there any provisions in laws and regulations regarding this?
Organic waste gas cannot be discharged through chimneys
It is not recommended to do this, mainly because the temperature of the process exhaust gases is very low; introducing them into the boiler chimney could significantly lower the temperature of these gases, possibly even bringing it below their dew point. Moreover, it is necessary to consult thermal engineering experts to determine whether a low flue gas temperature will have an impact on the boiler’s exhaust.
It is necessary to analyze the components and verify the gas requirements specified in the original design of the furnace
The treatment requirements have been met, so it can be discharged together
It’s best not to do this, as it will affect the proper operation of the boiler chimney
Obviously, it won’t work. It must be burned at least before it can be released.
Isn’t carbon dioxide waste gas usually discharged through a flare?
Although we do the same, it is still not recommended to do so.
