The color and temperature of a flame are dependent on the type of fuel involved in combustion. For instance, when a lighter is held to a candle, the applied heat causes the fuel molecules in the wax to vaporize, which is called pyrolysis. In this state, fire is always hot, but flames occur over a great temperature range. The coolest flame results from burning a regulated air-fuel.
The inner part of the flame, the closest to the wick, is the least hot. Types of flame color can come from the material that is being burned. There is a relationship between flame temperature and color, and a flame color temperature chart can explain how hot one is. For small flames (less than about 1 m base diameter), continuous flame region temperatures of around 900°C should be expected. For large pools, the latter.
When a flame burns cleanly like a gas flame, blow torch, or the base of a candle, the heat excites the molecules to release light, usually pale blue, from atomic transitions. Flames can vary in temperature from about 600°C to more than 3000°C, depending on the energy released from the fuel’s combustion. Acetylene, for example, burns at 1,500°C (2,730°F).
The hottest part of a candle flame is the blue part, at 1670°F (1400°C), where the flame has the most oxygen. The outer core of a candle flame burns at 1,400°C, while the core of the flame burns at 800°C. Most turbulent premixed flames are from engineered combustion systems, such as boilers and furnaces.
A cool flame is a flame having a typical temperature of about 400°C (752°F). The reaction is not vigorous, and tunnel fires can reach temperatures of over 1,000°C in just three to five minutes, with maximum temperatures up to 1.350°C.
📹 Aggressive Interior Fire Attack • First Due to Fairway Glen Working Fire
On Thursday April 14th, 2022, the Stockton Fire Department received multiple 9-1-1 calls for a house fire on Fairway Glen Street.
What burns at 1000 degrees?
The flame temperatures for common fuels are as follows: 1, 800°C for candles, 2, 121°C for carbon monoxide, 400–700°C for cigarettes, and 1, 960°C for ethanol. The adiabatic flame temperatures for air and oxygen are provided for illustrative purposes, indicating the theoretical maximum temperatures that could be achieved for each flame during combustion, assuming no heat exchange with the surrounding environment.
Are Black flames possible?
The scientific principles underlying the generation of black fire through the combination of salt and alcohol will be elucidated. This process results in the formation of a distinctive flame that absorbs light, and the role of sodium ions in imparting the flame’s dark coloration will be elucidated.
Does black fire exist?
In their discourse, the speaker articulates their affinity for the phenomenon of black fire and elucidates their most esteemed experiment on their channel, which they consider to be one of the most remarkable and impressive in person.
Is Black fire the hottest?
The hottest flames are violet, ultra-violet, indigo, and blue, which are often associated with cooler fires ranging from 1, 112 to 1, 472 degrees Fahrenheit (600 to 800 degrees Celsius). These flames are often associated with lighter fires, where there is limited oxygen supply or when the fuel burns at a slower rate. The temperature of fire varies depending on factors such as the type of fuel, oxygen availability, and specific chemical reactions within the flame. Red flames, which emerge at the lower end of the temperature scale, are common in gentle fires, such as smoldering coals or dying fires.
Are flames just hot air?
Fire is a visible side effect of matter changing form, as it occurs when oxygen in the atmosphere reacts with fuel like wood or gasoline. Fire doesn’t spontaneously catch on fire just because it’s surrounded by oxygen; it requires heat to ignite the fuel. The sequence of events in a typical wood fire involves heating the wood to a high temperature, which can come from various sources such as match, focused light, friction, lightning, or burning material.
How hot is the hottest part of a fire?
Blue fires can reach temperatures of 2, 552 to 2, 912 degrees Fahrenheit (1, 400 to 1, 600 degrees Celsius), while violet fires can reach up to 3, 000 degrees Fahrenheit (1, 650 degrees Celsius). The temperature of fire varies based on factors like fuel type, oxygen availability, and chemical reactions. Red flames are associated with cooler fires, ranging from 1, 112 to 1, 472 degrees Fahrenheit (600 to 800 degrees Celsius), indicating a more subdued combustion process. These flames are common in gentle fires, such as smoldering coals or dying fires, due to limited oxygen supply or slower fuel burning.
What part of a flame is hottest?
The outer zone of a flame is blue, indicating that it is the hottest due to the fact that it is undergoing complete combustion. In contrast, the middle zone is yellow, which is the brightest zone of the flame, due to the non-luminous part of the flame.
How hot is a room on fire?
Fires are fast, hot, and deadly, with room temperatures reaching up to 600 degrees at eye level. They can fill a house in minutes, and can be deadly due to the production of black smoke and toxic gases. Smoke alarms can significantly increase the chances of survival in a fire, but they should be replaced twice a year, installed on every level of the home, and replaced every 10 years. Disabling a smoke alarm while cooking can be fatal.
Audible alarms are available for visually impaired people, while vibrating pad or flashing light smoke alarms are available for the hearing impaired. It is crucial to be aware of these dangers and take necessary precautions to protect yourself and your family.
Where is the hottest part of a fire?
The portion of a flame exhibiting the greatest temperature is the blue component, which is situated in close proximity to the site of the chemical reaction. This may be observed in a fire where the wood is the reactant, or in a candle where the wick is in contact with the wax.
What is the hottest part of a lighter?
The innermost portion of the flame, which is characteristically blue in color, is the hottest due to the complete combustion of the fuel, with a temperature of approximately 1700 degrees Celsius. This makes it the hottest part of the flame.
How hot is the inside of a flame?
The temperature of orange flames ranges from 1100°C to 1200°C, while white flames are even hotter, reaching temperatures between 1300°C and 1500°C. Flames of a blue hue, with a blue base, exhibit a pronounced increase in temperature, reaching 2500°C to 3000°C.

As a captain on a large department I wanted you guys to know that 1. your articles are incredibly well edited and produced, 2. they are the best articles I have seen for table-top training, and 3. your department operates at a very high-level of skill and hustle; very, very impressive. Great job to all the firefighters doing the work and to the admin staff that produces these articles. They are incredibly useful to other departments and great PR for Stockton! Thank you.
While I cannot express my appreciation properly to ALL firefighters, I must state that of all the firefighter articles I have seen, Stockton’s Bravest show incredible hustle. No one walks. Deliberate speed and decision are the hallmarks, it seems. I’ve not seen others address the fire initially and followup at such speed, and get water on the fire as quickly. My hat is off to all you ladies and gentlemen.
As a retired firefighter of 22 years I have to say you guys have your act together. Obviously you have a fantastic training program, and your team approach to handling the fire ground is awesome! The citizens of your community should be honored to have you as their fire department and I hope the city council and or alderman of your city realize how well trained and how good of a fire department they have protecting them. To my brothers and sisters of the Stockton fire department you did a fantastic job, your pride and your commitment comes shining through. Stay safe and healthy. God bless.
You don’t get better than Stockton FD. Here in Seattle when we started the Medic One paramedic program we had departments from around the world coming to train here. I think Stockton could offer the same with their skills. They are up there with the London Fire Brigade, European and Australian Fire Services, other great services
Said many times, and will say it many more. SFD knows what’s important and that’s it’s important RIGHT NOW. Critical Tasks = Fire Attack, Search, Vent, Water Supply – RIGHT NOW. And not usually mentioned, the first due engineer is (or should be) the busiest person on the incident. Flaking and charging line, securing supply (assisted or not assisted), tools to point of entry, throw a ladder?, utilities? Passing info to next due companies. A “force multiplier”. Just a great example all around here. Again.
The strategies and tactics used on this fire was perfect. Great communication, defined roles, teamwork, it was all just so good. No one was screaming, everyone was calm cool and collected. That’s the kind of actions that deserve some well done accolades. Keep up the good work Stockton and hopefully other departments can learn from this and also utilize some article recording and editing to show a different style of doing things.
For most the articles I’ve ever watched from other departments they need to take note here, you can pull A-line, charge it and get to work fast without screwing around. This department time and time again shows how to do it and get it done quickly. These articles and department are some of the best I’ve seen on YouTube.
You can’t say enough good things about Stockton Fire. They are professional and they are impressive. These guys move very fluidly, they are very organized, have very little radio chatter and they put the wet stuff on the hot stuff as quick and as accurately as anybody in the USA. I would pair them up to anybody as being the best.
Excellent job SFD!! Quick question. Why do you beep over the address, but use a google map view that plainly shows the numbers for the house? I used to live in that neighborhood, on Silverado Court, back when all those houses were new. We fought hard to have the City build Station 4, so it was a real let down when I passed thorough the area a couple of years ago and saw it boarded up.
Having watched several articles here, and on other websites showing US departments, I have to wonder: Is SCBA usage a premium DLC you have to unlock? If I saw correctly, the second person of the roof vent team was not masked up, despite being in the smoke and opening up a smoke escape path. In other articles it seemed the captain had removed the mask while waiting inside the structure. Is there a reason to that? Nothing should be more important than the health of the firefighters, and nothing is more dangerous than smoke inhalation. And especially if you already have the SCBA on your back, masking up is a quick and easy step to reduce the risk of cancer. Other than that, the tactics seem to be effective, although I would never leave my partner alone, or let them go somewhere without me in the vicinity of the fire or inside the structure. Lastly, do US trucks carry some form of high-volume fans to assist in ventilation?
Wow. I’d have any of those guys on my squad any day of the week. Cudos to your trainer, whoever was IC and I must say that your pumper op and Knight are absolute beasts. You took an almost fully involved structure to the overhaul srtage in 2 minutes with one preconnect hoseline. It almost makes me cry to see guys this professional.
The time from arrival until there was water hitting the fire is incredible. This is the fastest work I ever have seen in these kinds of articles. Respect to the squad !!!! Very v e r y good job. There are articles where one house fire spreads to other buildings since it took the firefighters so long time and the heat caused the neighbouring house(s) to catch fire. I realize that there has to be security checks before, but it is not needed to have a water cannon going from the truck upon arrival.
First and foremost this is a genuine question, and it comes from no assumptions or accusations but is it a common practice for first team on scene to make entry without any rit team or back up in place? Where I live as far as I know we have to remain in a defensive position if we’re the only team on scene. Of course I didn’t get a full visual of the yard there could have been another company there but they t seemed like they literally hopped off the truck and made entry.
