I stand corrected. MY FRIEND WHO WORKS AT A POWER PLAND WAS WRONG. Here are the stats I dug up 6% TO OPERATE PLANT.
The steam is condensed for re-use. During this process the latent heat of condensation is lost to the cooling water. This is the major loss and is almost 40 % of the energy input. Losses in the turbine blades and exit losses at turbine end are some of the other losses. The Rankine cycle efficiency is dictated by the maximum temperature of steam that can be admitted into the turbine. Due to metallurgical constraints steam temperatures are at present limited to slightly more than 600 °C. The third stage converts the mechanical rotation to Electricity in a generator. Copper, magnetic and mechanical losses account for 5 % loss in the Generator. Another 3 % is lost in the step-up transformer which makes the power ready for transmission to the consumer.
To operate the power plant it is required to run various auxiliary equipment like pulverisers, fans, pumps and precipitators. The power to operate these auxiliaries has to come from the power plant itself. For large power plants around 6 % of the generator output is used for internal consumption.
This brings the overall efficiency of the power plant to around 33.5 %. This means we get only 1.9 kwhr of electrical energy from one kg of coal instead of the 5.56 kwhr that is theoretically available in the coal.
The efficiency or inefficiency of power plants is something that we have to live with for the present till technology finds away out.

Today's Featured Article - Field Modifications (Sins of the Farmer) - by Staff. Picture a new Chevrolet driving down the street without it's grill, right fender and trunk lid. Imagine a crude hole made in the hood to accommodate a new taller air cleaner, the fender wells cut away to make way for larger tires, and half of a sliding glass door used to replace the windshield. Top that off with an old set of '36 Ford headlight shells bolted to the hood. Pretty unlikely for a car... but for a tractor, this is pretty normal. It seems that more often than not they a
