Lithium bromide absorption heat pump and screw expansion power generation
Thread Content
There is some hot water at around 95 degrees, which was originally intended to be used in lithium bromide chiller units. I suddenly came across a document from Kai Shan: it mentions screw expansion power generation using 16.5 tons/h of saturated steam at 115 degrees Celsius, with an output of 933 KW per hour. If this system is converted into a lithium bromide absorption heat pump unit, could it be used to heat waste hot water to 115 degrees Celsius of saturated steam in order to generate electricity through expansion? Would the recovery efficiency in this case be high?

The lithium bromide adsorption heat pump uses hot water at 95 degrees Celsius to generate saturated steam at 115 degrees Celsius; doesn’t the process require a higher heat source? There is still economic value in generating electricity directly from 95-degree Celsius hot water
Can the efficiency of a hot water generator set be 20%?
When the temperature of the hot water is 100°C, the overall efficiency of the hot water generator set is 8%
