What Is a Gas Steam Boiler?

UN gas steam boiler is a type of boiler that utilizes natural gas or propane as fuel to heat water and generate steam. The resulting steam serves various purposes, such as heating buildings, alimentare i processi industriali, or generating electricity. Gas steam boilers find wide usage in residential, commerciale, and industrial settings.

How Does a Gas Steam Boiler Work?

Working principle of steam boiler

Gas steam boilers operate through the combustion of natural gas or propane in a burner. The heat generated during combustion transfers to the water-filled boiler, producing steam. This steam is then distributed through pipes to radiators, heat exchangers, or other heat-emitting devices, providing warmth or performing specific tasks.
