Energy-saving technologies for oxygen evacuation, recovery, and oxygen-enriched combustion in polysilicon nitrogen and hydrogen production
Thread Content
In October 2015, our company carried out a technical upgrade project at a polysilicon enterprise to implement oxygen evacuation and recovery, as well as oxygen-enriched combustion technology for energy savings. This project enabled the recovery of 800 cubic meters of pure oxygen for hydrogen production, and 3,500 cubic meters of oxygen for use in the nitrogen production facility. Pipelines totaling 1.5 kilometers were installed to deliver this oxygen to the boiler area, where it was used to enhance combustion and save energy. The project has now been debugged, allowing the manufacturer to save 30 million yuan in annual coal procurement costs. I think this is a very good energy-saving project, as it recycles oxygen produced by electricity to reduce the fuel consumption of boilers or thermal equipment. qq149908081 Welcome to add QQ for further discussion
Is oxygen-rich recovery used in fluidized bed boilers?
Two parts: one is used for fluidized bed boilers
It depends on the data; the original poster might as well do a simple calculation, such as the costs associated with modifying the boilers in power plants, as well as the requirements regarding the operating conditions of those plants
This can only be applied when the factory has available oxygen for discharge; it’s not cost-effective to build an oxygen production system on its own
Is oxygen-enriched combustion technology used in the petroleum refining industry?/
