The firetube boiler design (see Figures 1-1 & 1-2) uses tubes to direct the hot gases from the combustion process through the boiler to a safe point of discharge. The tubes are submerged in the boiler water and transfer the heat from the hot gases into the water. inside a firetube boiler the hot gases travel down the furnace
ChatTypes of High Pressure Boilers | Sciencing
When the temperature of the superheated steam is above the boiling point, it becomes a dry, pressured gas that is used to drive turbines. Most water-tube boiler designs have a capacity of 4,500 to 120,000 kilograms per hour of steam. Water-tube boilers in thermal power stations are also called steam generating units.

Chathp steam temperature from water tube boiler
Water tube boilers are designed with water inside the tubes of the boiler, while gases surround the tubes. As the water temperature increases steam begins to develop a travel to the upper portion of the boiler, typically called the steam drum. The cooler water travels through the down-comers to the mud drum, where the water will be reheated.
ChatThe History of the Steam-Generating Boiler and Industry
The number and size of the tubes, the type of fuel, and the overall physical dimensions of the boiler will all vary depending on what the boiler is designed to produce (water, steam, or heat) and the industry it is intended to serve (e.g., utility, industrial, medical).
