Write advantages and disadvantages of pulverized coal
Advantages of pulverized coal It increases the efficiency of the boiler. It makes possible the use of wide variety of coal. It reduces time of raising temperature of steam. Combustion of pulverized coal can readily be adopted
Explain cooling water cycle of a thermal power station
The condenser needs large amount of cooling water to condense the steam. This cooling water is circulated from lake or river, by means of circulating water pump and is returned back to the source. If sufficient quantity
Comparison between electric drive and mechanical drive
Electric drive Mechanical drive electric drive is dependent of electric supply, electric traction system is tried up to electrified routes only. It is self-contained unit and therefore can be suitable for any track. In case of failure
what is group drive ?
when one prime mover or motor is used for the number of machine tools on common shaft then the drive is called as group drive . it is also sometimes called as line shaft drive. Cost of
RISC architecture
RISC stands for reduced instruction set computer. It is a type of microprocessor architecture which utilizes a small, highly optimized instructions set rather than a more specialized set of instructions normally found in other types of architecture. Hence
