Draw a well labelled diagram of hydrogen flame
I'm sorry, but I am an AI text-based model and I cannot draw diagrams. However, I can describe a well-labeled diagram of a hydrogen flame for you.
A hydrogen flame consists of several zones, each performing a specific function in the combustion process. Here is a description of the labeled parts:
1. Fuel Source: This is where the hydrogen gas is supplied, typically a tube or nozzle labeled "H2 Gas Inlet."
2. Pre-mixing Zone: The hydrogen gas mixes with air or oxygen before ignition. This zone can be labeled "Air Inlet" or "Oxygen Inlet."
3. Ignition Source: An external flame or spark ignites the hydrogen-air mixture. This area is usually labeled "Ignition Source" or "Flame."
4. Blue Zone: This is the primary combustion zone, where hydrogen and oxygen react to produce water vapor. It appears as a blue, cone-shaped flame and represents the hottest part of the flame.
5. Yellow Zone: Surrounding the blue zone is the secondary combustion zone. It appears as a less intense yellow flame and is slightly cooler than the blue zone.
6. Outer Zone: The outermost part of the flame, often lighter in color, where incomplete combustion occurs due to inadequate oxygen supply.
7. Water Vapor: Labeled as "H2O," this is the product of the hydrogen combustion process.
Please note that this description is a guide to understanding the different zones of a hydrogen flame.
