Frequently Asked Questions (FAQs)
1. Is oxy propane better than oxy-acetylene?
Oxy propane and oxy-acetylene have different stoichiometric oxygen requirements. Propane requires more oxygen compared to acetylene. When using propane, a higher volume of oxygen is consumed. The choice between oxy propane and oxy-acetylene depends on the specific application and the desired flame characteristics.
2. What is the difference between yellow and blue propane torch?
The color of a propane torch flame indicates the temperature. A blue-colored flame indicates complete combustion and has a temperature of around 3,596° F. On the other hand, a yellow or orange flame indicates incomplete combustion, resulting in a lower temperature of about 1,832° F. Cooking with a yellow flame may lead to uneven temperature distribution.
3. How hot is an oxy propane flame?
An oxy propane flame burns at approximately 2,526 K (2,253 °C; 4,087 °F). The temperature of the flame depends on the specific fuel and oxygen mixture used. Oxy propane offers a high heat output, making it suitable for various applications where high temperatures are required.
4. Why can't you weld with oxy propane?
Welding with oxy propane is not recommended because the lack of hydrogen atoms in an oxygen-propane flame results in a redox reaction with the molten metal. This oxidizes the molten metal, leading to a brittle and weak weld that is prone to cracking or breaking. Other fuel gases, such as acetylene, are more suitable for welding applications.
5. Can I use an acetylene cutting torch with propane?
Using an acetylene cutting torch with propane requires certain modifications. The acetylene hose needs to be replaced with a propane hose, and the flash arrestor should be suitable for propane use. It is important to check the labels and ensure compatibility to safely use a propane cutting torch with an acetylene cutting torch setup.
6. How much does an oxy acetylene setup cost?
The initial setup cost of a medium-duty oxy-fuel system typically ranges from $230 to $500. The cost may vary depending on the brand, quality, and included accessories. Optional tips are available for cutting thicker steel.
7. Does propylene burn hotter than propane?
Yes, propylene burns hotter than propane. It combines the qualities of an acetylene flame with the secondary heating capacity of propane, resulting in a higher heat output. Propylene is often used in applications where a higher temperature is required.
8. What is the hottest burning propane torch?
The Benzomatic TS8000 Propane Torch is known for its high peak temperature. With a swirl flame design and increased fuel efficiency, it can reach temperatures of around 3000º F. This makes it one of the hottest burning propane torch heads available.
