What is A Burner for A Furnace?

A furnace burner is a vital element of your furnace system. Without it, it is impossible to produce heat. The burner is where the furnace combines air and fuel and then burns to generate heat. The furnace burner can be powered by various fuel sources, including oil or propane.

How do Furnace Burners Work?

The steps below outline how furnace burners work, from 303 Heat, the experts for furnace installation in Thornton, CO

  • The fuel enters through a valve and flows through an opening that can draw fresh air through venturi openings on the front of the burning. It is known as an in-shot burner. The fresh air and the gas are mixed within the burner, and an ignition device ignites the flame.
  • When the flame is released from the burner, it gets pushed through an S-shaped channel or metal heat exchanger. The S-shaped channel is designed to improve the time the flame makes contact with the heat exchanger to enhance its effectiveness.
  • According to our experts for HVAC repair in Thornton, CO, there are two heat exchangers in high-efficiency furnaces. The second is where the combustion air is pushed through various tiny tubes that absorb the heat.
  • The primary blower in your furnace draws air from your home through return air ductwork. It then blows it over the heat exchangers inside your furnace, taking the heat released from the heat exchanger and then delivering the heated air to every room using ductwork.

Burner Types

The kind of furnace burner your system requires will depend on various factors like the design of the furnace, its age, its condition, and its need for fuel.

In-shot Burners

Upshot Burners

These traditional design burners are found inside the natural draft furnace. However, they can be utilized in various buildings, and some of them have improved components to boost efficiency and meet modern performance standards.

Conversion Burners

The conversion burner is a device specifically designed to convert the fuel type. It is extremely beneficial when you want to alter the furnace fuel usage. For instance, you could put in a conversion burner to an oil-burning furnace that allows it to run on natural gas.

How Long do Furnace Burners Last?

In most cases, furnace burners are expected to last for the duration of the furnace’s life, i.e., 10-15 years; however, under damp conditions or when using propane gas, furnace burners can get rusty. Rusting is a concern that furnace burners must face since propane gas is highly corrosive.

According to our experts for HVAC repair in Thornton, CO, steel burners are installed in propane furnaces to eliminate the issue. If the burners are damaged, they will not allow the flames to travel down the burners, and the furnace won’t start up.
