Heating Furnaces Information
Heating furnaces convert gas, oil, electricity, or other fuels into heat for distribution within a structure. Heating furnaces are the central heating devices within HVAC systems. Heating, ventilation, and air conditioning (HVAC) are central systems in which one centrally located unit is used to heat, ventilate, and cool several rooms or an entire dwelling. HVAC systems also function as home heating furnace systems. A heating system furnace provides heat from a central furnace for a single building or a group of buildings. In large systems, steam or hot water is usually employed to distribute the heat. Furnaces for heating systems conventionally are fired with such fuels as oil, gas, or coal.
There are many types of heating furnaces. Examples include:
- induction heating furnace
- gas heating furnace
- heating oil furnace
- steam heating furnace
The induction heating furnace process relies on induced electrical currents within the material to produce heat. A gas heating furnace and heating oil furnace use gas and oil as fuel for heating and supplying the heat generated for heating purposes. Steam heating furnaces are used where cheap resources such as water are used for the production of steam are available. Other heating furnaces are commonly available.
There are several ways in which heating furnaces function. In an induction heating furnace, the heat is generated by using a power supply, which sends an alternating current through a coil, generating a magnetic field. When the work piece is placed in the coil, the magnetic field induces eddy currents. A gas heating furnace may include components such as a burner, heat exchanger, ductwork, a flue, or a vent pipe.
Gas furnaces are available in different sizes and efficiencies to meet HVAC replacement needs. A heating oil furnace uses fuel oil burned in a sealed chamber to heat an exchanger. A heating oil furnace warms the structure with the help of a blower and forces air across the exchanger into ductwork. A heating oil furnace uses the burner, heat exchanger, fire box, blower, and cabinet. Other accessories of a heating furnace include an air filter, electronic air cleaner, or high performance media filter, humidifier, and air conditioning evaporator coil. A condensate pump is used to remove the water discharged in the dehumidification action of the air conditioning. In steam furnaces, steam is led through pipes to radiators that are used for heating purposes. Heating furnaces can be designed and manufactured to meet most industry specifications.
Heating furnaces are used in many applications. Examples include their use in a home heating furnace, a heating treatment furnace, and a heating system furnace. A home heating furnace includes residential complexes for heating houses or apartments. A heating treatment furnace is used for disease disposal and a heating system furnace is used in industries where the temperature requirements are high.
Heating furnaces should adhere to Environmental Protection Agency (EPA) standards.
