Boiler - Wikipedia

Fire-tube boiler Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.

Gas Boiler Manufacturers Suppliers | IQS Directory

A boiler that uses natural gas as its heat generation method is hooked up to an external source of natural gas, which is directed into an enclosure near a supply of water. When the gas is burned in a gas boiler near a water reservoir, the water is heated; the heat is distributed in one of many different ways, depending on the boiler's configuration.
