Jul 08, 2014 · Generator (electric machine which generates electric power) shaft is driven by a turbine (gas, steam). Steam is produced in water-steam loop heated by a boiler. Total efficiency depends on efficiency of each of elements. In this chain generator is (usually) the most efficient element.
As water passes through the coil, the heat is transferred from the hot gases which causes the water to convert to steam. The generator design does not utilize a steam drum where the steam of a boiler has a disengagement area from the water in so the use of a steam/water separator to achieve 99.5% steam quality is required.

Sep 06, 2001 · Since one bhp equates to about 9.81 kW, and electric energy conversion in the boiler is about 98% efficient, the 10 bhp output requires 100 kW at the input. The operating cost is $5.00/hr. The energy per unit of fuel is based on charts published by the Institute of Gas Technology, Chicago, IL.
Jan 16, 2013 · Assuming that efficiency is measured by fuel heating value going in, and useful energy coming out--both electric output and waste heat put to use for heating or (paradoxically) cooling--the systems with the highest stated efficiency I have seen ar
While the steam engines that powered the industrial revolution were driven by externally-produced steam, modern combustion engines used for electric power generation are internal combustion engines in which an air-fuel mixture is compressed by a piston and ignited within a cylinder.
Don't purchase more fuel than will be used in a 3-month period. Use a fuel stabilizer along with fresh fuel when your engine is stored (follow the procedure noted in your owner's manual to ensure proper storage). Note that a fuel stabilizer will not reconstitute stale fuel. Use a gas station with a reputation for quality fuel.
