Hi I would like to ask the community if we can set up a post for a new energy system I have been working on ,I think it works out more efficient and ecologically better , and its large scale thinking for energy systems , and now I need to check through my figures and need the views of IET thinkers for instance on combustion , post combustion chemistry , it unfolds into quite a complex system which I have been working on for 8 years , but enables us to get more energy from wastes and perhaps helps to move to biomaterials. I have an interest as environmental thinker and have designed the system to go through to government funding phases and pretty confident it works well in a number of questions around energy and environmental thinking .
Hi Ho Hi Ho its off to work we go and its Monday hope everyone had a good weekend , I think we now have a 500MW power station capable of burning a variety of low grade wastes , at 6,125,000,000 KJ/Hr and an 80% efficient boiler means that 1,225,000,000 KJHR is lost as so termed stack losses , which could be exiting the furnace at anything from 200-400oC .
Each 1kg of water at 100oC makes 0,8m3 of water vapour , we have 318,000kg of water in our model so that's 254,400 m3h of water vapour however at around 300oC this would be double so 508,800m3 /hr as water vapour at 300oC same goes for the CO2 at 300oC of 488,000m3 , so perhaps a total gas/vapour of 996,800m3 hr or 16,613m3/min or 278 m3 sec .
But we still might have smoke/char uncombusted so If we combust again but this time using CH4 and O2 in a 90% efficient boiler , flame temperatures of 1800oC plus then we can pretty much break down (thermally) any organic chemistry molecule still present , into simpler molecules/oxides .A further third stage of combustion would ensure even the most difficult wastes could be thermally decomposed , I doubt we could use another 500MW modelling so lets use 250MW using around 50,000m3 of CH4 /hr and using 100,000m3 of O2 (plus any excess required) producing 50,000m3 of Co2 (100,000m3 at 300oC )and 75,000kg of water (60,000m3 of water vapour at 100oC , 120,000m3 at 300oC)
So we now an exit exhaust at the third stage of 998,000 m3 plus a further 200,000 m3 of CO2 and 240,000m3 of H20 at 300oC giving around 1,440,000 m3 /hr , 24,000m3 min , 400m3 sec, at the third stage exit of exhaust ,containing the culmative 950,000m3 of water vapour at 300oC , will be carrying considerable heat in the water vapour , which can be recovered an reused .
potentially then a theoretical 3 combustion stage 1000mw power plant making 440,000 m3 of CO2 (238,000kg) per hour (at NPT) and 440,000kg of H2O (at NPT), that is nearly half the CO2 output of the J.W Turk plant and 40% more electrical output. By using concurrent combustion , the stack loss of the previous stage is utilised , as well as getting the thermal decomposition to simpler molecules , and no NOX emissions and we can burn most of our organic problem wastes to simple molecules.
