Is your gas stove emitting orange flames? There is a big problem if this is the case. Your stove, your utensils, and your own health are all at risk if you cook with an orange flame.

In a way, our kitchen resembles a science lab. There are a lot of reactions going on in there every day, some of which could pose a danger.

We do a lot of cooking in our kitchen because of the stove. Excellent food, good health, and a well-functioning kitchen all depend on a stove’s flame. When the stove’s flame turns orange, there’s an issue that needs to be fixed immediately in order for it to function correctly and safely.

Why Is My Gas Stove Flame Orange?

This shows the presence of carbon monoxide, a byproduct of incomplete combustion, in the form of an orange flame. Problems with food, utensils, and your health can all result. The following are some of the most common causes of an orange flame:

  • Water vapor content in the atmosphere
  • Due to a buildup of soot in the stove, it becomes clogged.
  • Oxygen levels are too low.

Chemistry in the Kitchen

Getting to the bottom of that orange flame is the first step. It turns out that much of what you learned about chemistry in the lab can be found in your own kitchen. First, it’s important to grasp what’s going on with the flame on your gas stove.

Why Is The Flame On My Gas Stove Orange? The Best Guide! - Krostrade

Whatever you want to call it, all forms of natural gas are classified as hydrocarbons since they are the end product of carbon-hydrogen processes. Hydrocarbons, such as diesel, gasoline, coal, and methane, are all examples of hydrocarbons. Methane, the chemical name for natural gas, is the primary fuel in the vast majority of U.S. houses’ heating systems, including gas ranges and furnaces.

When a hydrocarbon combines with oxygen, it produces carbon dioxide gas and water vapor, which are the byproducts of burning. Analyze this chemical reaction in the following way:

CO2 and 2H2O are produced as a result of the following reaction: CH4 + 2O2

Ideally, this chemical reaction produces carbon dioxide and water vapor when the right amount of oxygen is combined with the optimum amount of methane.

Orange Flame

The color of the flame is a good measure of how much heat is being produced by the combustion process. If the gas and oxygen are mixed properly, a hissing blue flame will result; this is an indication that the stove is working properly. However, an incorrect combination will result in an orange flame, which you now know to be extremely hazardous. ”

The Risk of Incomplete Combustion

Completing the process of combustion results in carbon monoxide and water instead of carbon dioxide and water when the right mixture of fuel and oxygen is used. It’s possible that the following equation will assist you better comprehend;

hydrogen and oxygen produce carbon dioxide, carbon monoxide and water.

Formaldehyde, methanol, and formic acid are among the various partially oxidized compounds that can be produced as a result of incomplete methane combustion.

If the flame on your gas stove is hissing blue, then adequate combustion is taking place, resulting in normal levels of carbon monoxide being produced. As a result, orange flames indicate an increased concentration of CO gas, which is harmful to human health, kitchenware and even house decor.

When there is inadequate ventilation, carbon monoxide can be a silent murderer if left unchecked. Because of its colorless and odorless properties, it can kill when it’s least suspected. A good rule of thumb is to never use a gas stove to heat your home if it doesn’t have a vent. Even the purportedly healthful blue flame emits some CO, which can be deadly if it accumulates in poorly ventilated areas. This is a surprising fact.

Carbon monoxide poisoning symptoms include the following:

  • Dizziness
  • Drowsiness
  • Fatigue
  • Convulsions
  • Confusion
  • Fainting
  • Coma
  • Increased apprehension
  • an all-over feeling of exhaustion and fatigue
  • Impairment of decision-making
  • Shock
  • Vomiting and diarrhoea
  • Heart rate abnormality
  • Blood pressure is low
  • Hyperactivity
  • Myofascial atrophy
  • Breath difficulties (rapid breathing, no breathing, and shortness of breath)
  • Chest aches that come on suddenly

When you fire a gas stove, the flame is orange because of soot that hasn’t burned completely. Inhaling soot can develop and worsen respiratory allergies, which is why it’s dangerous. The utensils and cookware become more difficult to clean when coated in soot. Your white ceiling boards and cabinets will be ruined, as will the rest of your house’s decor.

Causes of Fuel-Oxygen Mixture Imbalance

The orange flame on your gas stove can be caused by a variety of factors, including faulty combustion.

Clogged Burner Orifices

Keep in mind that incomplete combustion produces soot, and soot attaches to surfaces such as burner orifices and other components. The gas stove burner orifices become caked with soot as the combustion process continues, preventing appropriate air passage. Burning soot is the source of the bright orange glow.

Additionally, the soot acts as a barrier to portion of the gas, resulting in cooler orange flames and air pockets. While the remainder of the natural gas is being wasted, only a fraction of it is used to generate the high temperature. Gas waste can significantly raise your monthly expenses.

Increased Humidity

If the gas stove is in the same room as a humidifier, the increased humidity may cause the blue flame to become yellow.

Does Your Gas Stove Have An Orange Flame? Here's Why

Wrong Orifices

Depending on the type of carbon fuel used in the gas stove, a varied proportion of air and fuel is needed to achieve complete combustion. In the case of natural gas, for example, it will need more air than liquid propane. It’s possible that the manufacturer placed the air shutter incorrectly or that the burner you purchased isn’t compatible with your gas stove if you have a brand new one and notice an orange flame.

Food spillage

When the pot is left unattended, food and drink can spill onto the burner. We’ve all had the experience of milk pouring unexpectedly. Your gas stove burner may light up with a bright yellow glow if you burn food particles.

How to Fix An Orange Flame On Your Gas Stove

Don’t worry about the orange flame just yet because it isn’t a hazard on its own and will only pose a danger if it isn’t addressed. Fixing a bright orange flame can be done in this manner.

Clean Burners

Soot builds up on the gas stove burner’s microscopic holes due to incomplete combustion, which demands regular cleaning. Be careful not to leave any clogs in the burner’s holes or the igniter as you clean it.

Remove any food or debris from the burners by thoroughly cleaning them. The yellow tint inside the blue flame is caused by cooking spillage, such as grease, milk, and other food residues, burning on the gas stove burner.

Make sure to return all of the gas stove’s components to their proper locations during cleaning and maintenance, as the improper positioning of components can alter the flame color.

Proper Orifices

For natural fuels, the air-fuel mixture ratio is not the same. When using natural gas, be sure that your burner has orifices that are compatible with natural gas. Additionally, you’ll want to tweak the brass aperture and the gas pressure control valve.

More air, please

Changing the color of the flame on a gas stove burner may be caused by an imbalance in the air to fuel ratio due to improper ventilation. Incomplete combustion and the risk of asphyxia can result from the stove and its users competing for oxygen in a small kitchen with poor ventilation. You should let in as much fresh air as possible by opening all of the doors and windows. If the burner isn’t working properly, open the air shutter as far as it will go.


Skin glows and sinus infection symptoms are eased when there is high humidity in the air. It is, however, a bad idea to use a humidifier in conjunction with a natural gas stove, as this can lead to yellow flames. A humidifier should be turned off while you’re cooking on a gas stove burner in a room with a humidifier, such the kitchen.

Dismantling and reassembling

It’s worth a go because it has worked in some circumstances. When you remove the stove’s top grate and lift the top, you will be able to see and access the burner pipes. The burner’s air vent is frequently covered by a plate or tube hidden behind the gas valves, which are also known as air shutters. To remove the shutter, simply pry it open with a screwdriver. Once the burner is lit and the air shutters are adjusted to a full blue flame, the job is done. Last but not least, reinstall the stovetop and top grates, tighten the screws, turn off the burner, and clean them.
