Combustion Chemistry: Meaning of OH, H2O2 in Combustion

Click For Summary
SUMMARY

The discussion focuses on the roles of hydroxyl radicals (OH) and hydrogen peroxide (H2O2) in combustion chemistry. OH is identified as a negatively charged radical that plays a significant role in various combustion reactions, while H2O2 is recognized as hydrogen peroxide, which can also appear in combustion processes. The formation of these species indicates specific chemical reactions occurring within flames, impacting combustion efficiency and characteristics. Understanding these species is crucial for analyzing combustion mechanisms and optimizing fuel performance.

PREREQUISITES
  • Basic knowledge of combustion chemistry
  • Familiarity with radical species in chemical reactions
  • Understanding of flame characteristics and behavior
  • Knowledge of chemical reaction mechanisms
NEXT STEPS
  • Research the role of hydroxyl radicals (OH) in combustion processes
  • Study the formation and effects of hydrogen peroxide (H2O2) in flames
  • Explore combustion reaction mechanisms and their implications
  • Investigate the impact of radical species on combustion efficiency
USEFUL FOR

Chemists, combustion engineers, and researchers interested in the mechanisms of combustion and the effects of radical species on flame behavior.

What is the meaning of the appearance of the following species in a combustion:

-OH

-H2O2
 
Engineering news on Phys.org
Where do they appear ?
 
thousands of reactions occur in the combustion...
I want to know what is the meaning of the appearance of each species...:smile:
 
I don't understand your question. If it appears in the combustion reaction, it is being formed. Why should there be a meaning associated with that ?
If it appears in a textbook or in an article, you might help us assist you by quoting some more context.
OH- is usually a negatively charged radical. ##\ ## -OH can mean a lot of things, including OH-
H2O2 is hydrogen peroxide. -H2O2 could be a doubly negative radical H2O22-
 
No, not meaning like that
For example appearance of CH2O shows cool flame...
 
I see. You want to know what causes the formation of OH- and/or H2O22- ( or just H2O2 ?) in a flame !
A bit like http://www.icders.org/ICDERS2011/PapersICDERS2011/ICDERS2011-0328.pdf ?
