It is a 3,520,000kilowatt coalfired facility that provides electricity for Georgia. As this diagram shows, the plant operates on the same principles as other fossilfueled electric generating plants—it burns coal to produce heat that turns water into steam, which then turns turbines in a generator.

In the boiler system, the combustion process and heat transfer process in the furnace are the two most critical steps. Increasing combustion efficiency and heat transfer efficiency is conducive to energy saving and consumption reduction, increasing the economic benefits of coal fired power stations, and having a greater impact on the operational economics of boiler equipment. The thermal ...

The biggest limit of energy production of steam engines is the Carnot cycle ƞ=(T maxT min)/T max.. The efficiency even of the most modern coal power plants is ~ 30%.It means that ~70% of the produced energy gets out to the air when burning coal, and that means the same amount of the unnecessary CO 2 emission as well. The efficiency of locomotives is even worse.
