Spray Ponds and Cooling Towers 7. Control Room 8. Switchyard 1. Steam Generating Equipment: (a) Boilers: Boilers or steam generators convert water into steam and form one of the [...]
Steam power plant basically operates on the Rankine cycle. Coal is burnt in a boiler, which converts water into steam. The steam is expanded in a turbine, which produces mechanical power driving the alternator coupled to the turbine. The steam after expansion in prime mover (turbine) is usually condensed in a condenser to be fed into the boiler again. In [...]
The factors to be considered while selecting a site for a steam power plant for economical and efficient generation are: 1. Nearness to the Load Centre 2. Supply of Water 3. Availability of Coal 4. Land Requirement 5. Type of Land 6. Transportation Facilities 7. Labour Supplies 8. Ash Disposal 9. Distance from Populated Area. Factor # 1. Nearness to [...]
