Heat you feel when you sit next to a campfire
With campfire season underway, it's important to be aware of possible burn risks.
“It happened so fast I didn’t have time to move out of the way. I was engulfed in flames!” A quote from my 21-year-old nephew who is now being treated in a burn unit for second and third-degree burns. The accident happened when the campfire pit that he was sitting by was ignited when people threw accelerants into the fire. The flames jumped over 10 feet and engulfed him and his clothing.
Campfire accidents just like this send thousands of people to emergency rooms each year. Contributing to those burn accidents is sitting too close and wearing flammable (fabrics that ignite quickly) clothing like cotton and cellulosic fibers such as linen, rayon, lyocell and ramie. Safety tips include having enough room around you to make a quick exit, and wearing quick release vests or clothing that can be easily pulled off should they ignite.
Flameless burns
Skin can be burned without being touched directly by the flame. Clothing can also be ignited without an open flame. Being in a closed space without an exit can contribute to what are called radiant burns. Radiant heat means there is no
What's The Science Behind A Good Propane Fire Pit?
Propane campfires rely on a few simple principles to make you warm. Some generate Infrared heat, while others only have flames. Some burn a ton of BTUs, while others burn less fuel. Some have lava rocks, while others don’t.
So how can you tell which propane fire pit will bring the heat?
Why Do People Use Propane Firepits?
Campers are using portable propane fire pits in record numbers, and more companies than ever are building them.
Sure, propane fires are more convenient and easier to use than wood fires. But the big reason so many campers are making the shift is because of burn bans. About 84% of wildfires are started by humans (Smithsonian), and to protect our forests, land managers frequently impose bans on burning wood and charcoal. It’s hard to know where and when these bans will be in effect, and that surprises campers, leaving them without a fire.
The solution is to camp with a portable propane fire pit. They’re allowed in most burn bans because they’re safer for forests, and propane is often the only legal way to have a fire while camping.
The Basics of Propane Fire Pits
Propane fires come in many different shape
While sitting near a heater or a bonfire, you feel warm. The heat from the heater reaches you by process

When I sit by a campfire, how does its hot gas heat me?

When you sit by a campfire, most of the heat you are receiving from the blaze does not come from boiling air. It comes from thermal radiation.
Generally, there are three ways that heat can travel: radiation, conduction, and convection. Thermal radiation consists of electromagnetic waves (mostly infrared waves and visible light) emitted by an object due to its temperature. This radiation carries energy which is converted to heat when it hits another object and is absorbed. In contrast, conduction involves the direct movement of heat through an object. Since air is a good thermal insulator, conduction is the least effective way for heat to travel through air. Lastly, convection involves the bulk movement of pockets of heated fluid. In convection, a pocket of fluid such as air or water gets heated and then moved somewhere else by fluid currents.
