What is a boiler?

Fuel Combustion: The fuel, such as natural gas or oil, is burned in a combustion chamber or burner. The combustion process releases heat energy.

Heat Exchanger: The heat produced from combustion is transferred to a heat exchanger, which is a series of pipes or tubes. The heat exchanger is designed to maximize the transfer of heat from the hot gases to the water or fluid.

Water/Fluid Circulation: The heated water or fluid circulates through the pipes or tubing, either by natural convection or with the help of a pump. This circulating system carries the heat to the desired location, such as radiators, baseboard heaters, or other heat emitters.

Heat Transfer: The heat is released from the circulating water or fluid at the heat emitters, which warm up the surrounding air or objects. In the case of steam boilers, the heat is used to generate steam, which can be used for heating or to power engines and equipment.

Condensation and Exhaust: In some high-efficiency boilers, flue gases may be condensed to extract additional heat before being expelled through a flue or chimney. This reduces fuel consumption and improves efficiency.

Control System: Boilers are equipped with control systems that regulate and maintain the desired temperature and pressure. These systems ensure safe and efficient operation.
