Air Preheaters (APH) are important equipments in modern thermal power stations. By preheating the combustion air with the hot flue gases coming out of the boiler, a considerable increase in efficiency is obtained.
A computer consume an average of 700-1000 watt. It varries due to the efficiency of computer and other extra audio devices, power supply Eg:ups, home theatre, speaker etc..
The conversion efficiency n of a rectifier ckt is generally defined as Na= dc power delivered to the load/ ac power input to the rectifier ckt. Or n = Pdc/Pac
BMCR is the boiler maximum continous rating .It is that the maximum temperature , steam flow or the pressure that is used to generate full load or the bolier can withstand.TMCR is the turbine maximum continous rating .It is that the maximum temperature , steam flow or the pressure that the turbine requires for generating full loadNOTE:BMCR WILL BE MORE COMPARED TO TMCR
The official name for it is Biomass, which means using plant material as a fuel for some sort of power plant

A modern combined cycle gas turbine/ steam turbine power plant can reach almost 60% efficiency.
It is the efficiency of the power plant.

It is always desirable to run any equipment or device at maximum efficiency for that matter, not only the power transformer. Power transformer maximum efficiency occurs when copper loss is equal to iron loss. (or no load loss equals to load loss). This does not necessariliy mean that maximum efficiency occurs at maximum or full load. Generally the maximum efficiency occurs at relatively less than full load of the transformer.
It is maximum at about 75% to 100% of the motor rated load. Efficiency is maximum at unity power factor , when R=X and when variable losses Is equal to constant losses at rated load.

The energy efficiency of a typical nuclear power plant varies, depending on its design, but a typical value might be around 33%.
generator
It is around 35 to 40 %

Power factor ranges from zero to a maximum of 1. At 1 the current and voltage waveforms are in phase and operate at maximum efficiency.
