Different parts of boiler such as economizer, super heater, re heater, water wall and steam drum are illustrated here. This video also explains an important concept during boiler heat addition process. Watch the video from Learn Engineering for more info:
A boiler or steam generator is a device used to create steam by applying heat energy to water.These hot gasses come in contact with water vessel where the heat of these hot gases transfer to the water and consequently steam is produced in the boiler.
Then this steam is piped to the turbine of thermal power plant. The higher the furnace temperature, the faster the steam production. The saturated steam thus produced can then either be used immediately to produce power via a turbine and alternator.//Learn Engineering
