What are the 4 types of gas fired furnaces?
The National Fuel Gas Code (NFPA 54) identifies four categories for combustion furnaces and water heaters based on combustion type (sealed or unsealed), vent pipe pressure, and vent pipe temperature.
How do gas fired furnaces work?
Here is the simple version: Burning propane or natural gas generates heat in the furnace’s burner. The heat produced passes through a heat exchanger, making it hot. Air from the home’s ductwork is blown over the heat exchanger, warming the air.
What is gas furnace?
A gas furnace is a home heating appliance that runs off of natural gas. The natural gas is ignited in the furnace, warming up the air, which is then delivered throughout the home. A fully functioning gas furnace requires all of its components to be working in sync.
What type of gas is a furnace?
Natural gas This is the most common type of furnace in U.S. homes. They run on natural gas piped from a municipal supply. This fuels the burners that create a hot combustion gas that is transferred to the air blown through the ventilation system.
What is a gas furnace?
What is furnace and its types?
There are four main types of furnaces: natural gas, oil, electric, and propane. Electric furnaces can heat the air by exposing heated elements, while other types of furnaces typically require a heat exchanger or chamber that warms the surrounding air.
What are the components of a gas furnace?
The main parts of your furnace are the control system (thermostat and electrical controls), gas valve, burners, heat exchanger, blower, and duct and ventilation system. When your furnace creates heat, combustion gases are vented out of your home via a flue pipe.
What is a gas furnace made of?
Raw Materials. Today’s modern furnace uses stainless steel, aluminized steel, aluminum, brass, copper, and fiberglass. Stainless steel is used in the heat exchangers for corrosion resistance. Aluminized steel is used to construct the frame, blowers, and burners.
