Blue flame vs red flames is an issue of safety, proper combustion and saving gas. Gas normally burns with a blue flame but sometimes it burns with yellow or red flames when there is a problem. Flame Colour Meaning Flame colour meaning can be indicative of temperature, type of fuel or the completeness of combustion.
What is the difference between red and blue flame?
Characteristics of Poor Quality Kerosene:
- Yellow or cloudy tinted
- Visible dirt, debris, dust, or contaminates
- Bubbles of water collected at the bottom of the container
- Improperly stored in an uncertified container
- Stored in direct sunlight or high heat
- Stored for an extended period of time (more than 3 months or from previous seasons)
Why is a blue flame hotter than a red flame?
When matter has thermal energy (all matter does, as far as we know), it emmits electromagnetic energy. The frequency of this energy is dependent upon the amount of thermal energy the matter possesses. So, objects that glow blue would be hotter than an object that glows red due to heat.
Why is a blue flame better than a yellow flame?
Why is blue flame of gas stove considered better than orange flame? Blue flames are hotter and indicate more complete combustion. If your flame is yellow or orange, or if you see pops of yellow or orange, that is a sign that you have a combustion problem that should be addressed by a professional.
What gas burns with a blue flame?
You will see blue flames on:
- Bunsen burners
- Gas stoves
- Deep fryers
- Furnaces
Is blue flame stronger than red flame?
When temperatures approach 2,400º F to 2,700º F, flames appear white. ,that's the reason the blue flame is more hotter than a red flame. ,that's the reason the blue flame is more hotter than a red flame.
What is the strongest color of flame?
For a given flame's region, the closer to white on this scale, the hotter that section of the flame is. The transitions are often apparent in fires, in which the color emitted closest to the fuel is white, with an orange section above it, and reddish flames the highest of all.
What is the difference between red fire and blue fire?
The farther away from the fuel source that the flame reaches, temperature decreases, leading to the bulk of a flame often being orange while the tip is red. ... Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood.
Is Black fire Possible?
Flames emits light and heat, so it seems impossible to make black fire. However, you actually can make black fire by controlling the wavelengths of absorbed and emitted light.29-Sept-2018
What is the least hottest fire color?

The inner core of the candle flame is light blue, with a temperature of around 1800 K (1500 °C).09-Dec-2021
What is the hottest type of fire?
Blue flamesBlue flames are the hottest, followed by white. After that, yellow, orange and red are the common colours you'll see in most fires. It's interesting to note that, despite the common use of blue as a cold colour, and red as a hot colour – as they are on taps, for instance – it's the opposite for fire.
Is blue fire hotter than magma?
Is a blue flame hotter than lava? While lava can be as hot as 2200 F, some flames can be much hotter, such as 3600 F or more, while a candle flame can be as low as 1800 F. Lava is hotter than a typical wood or coal-buring fire, but some flames, such as that of an acetylene torch, is hotter than lava.08-Dec-2021
What is the coldest fire?
A cool flame is a flame having maximal temperature below about 400 °C (752 °F). It is usually produced in a chemical reaction of a certain fuel-air mixture. Contrary to conventional flame, the reaction is not vigorous and releases very little heat, light, and carbon dioxide.
What does a blue flame mean?
, Interested in Chemistry, Quantum Mechanics, Hinduism.. Answered 2 years ago. Keeping it short and simple, a blue flame is the sign of complete combustion, which means that more of the bonds of the concerned fuel would be broken down, releasing greater bond energy of dissociation and thus greater heat….
What determines the color of a flame?
In the most common type of flame, hydrocarbon flames, the most important factor determining color is oxygen supply and the extent of fuel-oxygen pre-mixing, which determines the rate of combustion and thus the temperature and reaction paths, thereby producing different color hues.
What color is the flame in a candle?
Colors tell us the temperature of the flame.Outer zoneMiddle zoneInner zoneThe outermost zone is the hottest among all zones and is blue in color, and this is due to complete combustion.
Why is propane blue?
LPG (propane) and natural gas (methane) flame colour are both blue because they go through complete combustion with no by-products. Of course, complete combustion will burn hotter, meaning that a blue flame will be hotter than a red/yellow flame.
Which is a more efficient combustion?
This depends upon the combustion. Propane has the hottest part of the flame as blue. It is a more efficient combustion. On the other hand, flame with a less efficient combustion will go from white at the hottest to yellow to orange to red. Judas Priest is one of my favorite bands.
Why do campfires turn green?
These have nothing to do with copper. Instead, the blue and green colors are due to Swan bands, which are light emitted by C-C molecules. Swan bands also turn up in the light emitted from comets, which is why they often have a blue-green color.
What is the process of burning methane?
This process is called complete combustion, as there are no waste products, and will burn with a Blue Flame. If the supply of oxygen was limited, the methane will react → producing some [toxic] Carbon Monoxide (CO). This will burn with a red/yellow flame, signifying incomplete combustion. Inc.
What do the colors of fire represent?
The flames of a fire have several different colors. The colors in the flames represent the different substances that are undergoing combustion in the fire. Hotter fires burn with more energy which are different colors than cooler fires.
What is the reaction between a fuel and oxygen called?
Most fires are the result of a chemical reaction between a fuel and oxygen called combustion. Temperatures gradually rise during combustion and flames occur once the temperature rises to the point for the fuel to vaporize and combine with oxygen. A red glow is produced when temperatures are about 932°F. Red flames occur at 1112-1832°F and turn orange between 1832-2192°F. At 2192-2552°F the flames turn yellow and if they get hotter the flames become blue-violet.
What is the difference between a blue flame and a yellow flame?
Blue and Yellow Flame. As it relates to hydrocarbon gases, blue flame is indicative of complete combustion whilst a yellow flame indicates incomplete combustion. An LPG blue flame also burns hotter, at around 1,980°C, vs about 1,000°C for a yellow flame.
What does a blue flame mean in a gas burner?
A natural gas blue flame indicates that the burner is providing the correct air-fuel mixture, with sufficient oxygen for complete combustion at the burner. A blue flame burns the fuel completely producing carbon dioxide, water and heat. The natural gas flame temperature is about 1,960°C.
What does a yellow flame on a gas stove mean?
A gas cooker yellow flame indicates a combustion problem. A gas cooker or stove should have a blue flame. Gas stove temperature is not the same as the gas flame temperature, which has a maximum of almost 2,000°C. The actual gas stove temperature range is typically from about 90°C to no more than 300°C.
What causes a flame to turn yellow?
The flame colour changes to orange, yellow or red flame and the flame wavers. The yellow/orange/red colour is created by carbon soot particles in the flame, produced as the result of incomplete methane gas combustion.
What does it mean when a propane flame is red?
Red flames or propane-natural gas flame color orange, instead of a blue flame, may mean signs of incomplete combustion, wasted gas and a serious safety hazard . With hydrocarbon flames, such as gas, the amount of oxygen supplied with the gas determines the rate of gas combustion, flame colour and temperature.
What color does methane burn?
Methane gas does also burn with a yellow, orange or red color, when there is incomplete combustion, with a methane gas flame temperature is about 1,000 °C. Ethane, propane, butane and isobutane do also burn with a blue flame color. Methane gas is the primary constituent of natural gas and it burns with a blue color flame.
What gas has a blue flame?
Pure hydrocarbons like methane (refined natural gas), propane, butane and ethane gases also burn with a blue flame. These gases are all alkanes and are gas that burns with a blue flame. These gases come from raw natural gas processing and oil refining.
What color is the flame?
Instead, the color of the flame depends on what exactly is the chemical that you’re burning, what’s the frequency of the light it produces ( higher frequency is blueish and lower freque ncy is reddish), and several other factors.
How does an infrared heater work?
Infrared radiant heaters. These heaters are designed to deliver a direct radiant heat by using electromagnetic radiation, not unlike the sun. This means that they don’t heat the air around them but instead heat the physical objects in the room directly – the closer an object is to the heater, the quicker it will get warmed up.
Can a flame heater work in poorly insulated rooms?
This is a huge plus for poorly insulated spaces that can’t be heated effectively with a flame heater.
Is a blue flame heater better than an infrared heater?
Generally, however, as long as the room is well isolated, a blue flame heater will be the better and safer choice while infrared heaters are better used in poorly insulated spaces.
Can a blue flame heater work with propane?
Both blue flame heaters and infrared – or radiant – heaters can work with either natural gas or liquid propane. Also, both types are vent-free, often portable, and work with 99.9% efficiency. However, they deliver heat in a very different manner and each has its advantages and disadvantages, many of which are largely subjective. ...
Can blue flame heaters be used indoors?
Blue flame heaters should be used almost exclusively in well-insulated indoor, and medium-sized areas as they would be inefficient if the air around them is too much for their heating capacity.
Can infrared heaters ignite?
The main – and quite significant – drawback of infrared heaters is that they can easily ignite nearby objects if they are flammable. This means that you’ll need to set them up on a place where they can give you enough heat but there are no flammable objects nearby.
What is the difference between a blue flame and an infrared heater?
Using an additional heat source in the most used area of your home allows you to lower the thermostat in the rest of the house, which can help you save in energy costs. Blue-flame heaters are ideal for insulated spaces, while infrared heaters work best in uninsulated areas.
Why do blue flame ceiling fans work?
The heat then moves up toward the ceiling to eventually heat the entire room. Because blue-flame heaters heat the air vs objects in a room, they’re ideal for insulated spaces. A ceiling fan with the blades reversed can help to circulate the warm air and make the heater more efficient.
How does radiant infrared heat work?
This means they use electromagnetic radiation — just like the sun — to directly heat objects in the room. With radiant infrared heat, there’s no waiting to get warm — you’ll be warm instantly, just as if you were standing in front of a fire. Because infrared heaters transfer heat directly to objects, they’re ideal for uninsulated spaces such as ...
Do infrared heaters have ODS?
Both infrared and blue-flame heaters have Oxygen Depletion Sensors (ODS), which will shut off the heater before it reaches an unsafe level. Both are vent-free heaters. Since vent-free heaters add moisture to a room, it’s wise to periodically open a door or window while running your heater.
What is a Blue Flame Heater?
A blue flame heater is a portable space heating device that burns air and fuel to produce heat energy. There are four types of space heaters: convection, radiant, infrared, and ceramic.
Is a Blue Flame Heater Safe?
According to the manufacturer’s guidelines, a blue flame heater is generally safe if you use it and take basic safety precautions. One significant risk associated with blue flame heaters is that they can cause carbon monoxide poisoning.
How does a Blue Flame Heater Work?
A blue flame heater works by burning an optimal mixture of either natural gas or propane with oxygen. It then produces heat through its front panel. The heat from your blue flame heater direct heats the air in the room.
