Pitch

Use stack gas temperature to run a Rankine Heat Engine to produce electrical power and reduce GHG's.


Description

Summary

Place a heat exchanger in the flue gas stream going to stack to boil freon or ammonia to run a Rankine closed loop cycle turbine  to produce electrical power... Stack exit temperatures can be as high as 230 degrees F which is plenty warm enough to boil off freon or ammonia to run a turbine generator..

Category of the action

Reducing emissions from electric power sector.


What actions do you propose?

Per the summary above by doing so these actions can reduce GHG's about 7% per site and that electrical energy can be sold to the community or used as auxiliary power for the site thus lowering the heat rate of the unit. Deep cool well water at the sites can be used in another heat exchanger as the condensing medium.. The idea can reduce many of the ill effects of climate change that fossil fuels are bringing us today. The governments "Climate Action Plan" would help fund the idea: http://www.whitehouse.gov/climate-change


Who will take these actions?

Existing power plant businesses can install such systems mandated by the government to lower fuel costs and GHG emissions. The governments "Climate Action Plan" would help fund the idea: http://www.whitehouse.gov/climate-change


Where will these actions be taken?

All power plant locations or other factories with exhaust gasses going to a stack..


How much will emissions be reduced or sequestered vs. business as usual levels?

 This idea can recover about 7 megawatts of energy out of every 100 mw  of energy generated or 7%..


What are other key benefits?

The idea can reduce many of the ill effects of climate change that fossil fuels are bringing us today such as Co2. SOX, NOX, particulate matter, smog, higher sea levels, higher sea surface temperatures, red tide,hypoxic oceans, lower PH levels in our oceans, coral bleaching, loss of Northern summertime arctic ice, Loss of the Antarctic Ice shelf, loss of albedo, skin cancer,Loss of Methane Hydrates, Melt of Arctic Tundra, lung cancer, war, heart attacks, stroke, asthma, loss of polar bears, sea lions, narwhals, walrus, krill, shrimp, rain forest's, soil moisture, more desertification and prevents fracking. etc. etc. etc.


What are the proposal’s costs?

Few million dollars per unit.


Time line

Phased in 5-15 years as demanded by governments and Laws.
