Steam generator (component of prime mover) A boiler incorporates a firebox or furnace in order to burn the fuel and generate heat. The generated heat is transferred to water to make steam, the process of boiling. This produces saturated steam at a rate which can vary according to the pressure above the boiling water.
Steam generators. In many applications: The amount of steam required is too small to warrant a shell boiler, i.e. Less than 1 000 kg / h. The small process requiring steam operates on a day shift only, meaning that the plant would be started every morning and shut down every night.
Classification of Steam Heating Systems - Steam systems carries heat through pipes from the boiler to consumers as heat exchangers, process equipment etc. Condensate Generation in Cold Steam Pipes - Sizing of Steam Traps - When cold steam pipes are heated up they generate huge amounts of condensate that must be drained away from the pipe through steam traps - in Imperial Units

The way that a steam boiler works is a straightforward process that aligns with the natural heating, cooling and condensation process. In most cases, raw water is fed into the boiler from a pipe system. That water is then purified to clean it of any debris.
The primary purpose of the boiler is to supply energy to the facility's operations – for comfort heating, manufacturing process, laundry, kitchen, etc. The nature of the facility's operation will dictate whether a steam or hot water boiler should be used. Hot water is commonly used in heating applications, with the boiler supplying water to the system at 120°F to 220°F.
There are two common designs for a steam boiler: firetube and watertube. In a firetube design, a steam boiler is a pressure vessel comprised of a large shell in which the hot gases of combustion pass through one or more boiler tubes connected to the front and rear boiler sheet.
