Industrial production of carbon dioxide gas using a boiler is one of the methods of producing this gas. In this method, carbon dioxide is placed inside the boiler as a raw material and by applying heat and pressure, it turns into carbonic gas. Boilers are used in various industries for steam production, heating and other industrial processes. In some cases, carbon dioxide is placed inside the boiler in liquid form and by applying pressure and heat, it evaporates and is released as carbon dioxide. The use of boilers to produce carbonic gas is used in some industries such as the beverage industry and food industry. This method of producing carbon dioxide is considered in some cases due to its simplicity and efficiency.
