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 .
The old steam guys certainly did know a lot , which is why they needed superheated steam for pistions and cylinders , the steam turbine changes things a little as its more to do with flow rate and how low you can get the pressure at the exhaust , Water vapour , superheated is carrying a lot of heat , which is why steam has continued in some processes however if we use the spent steam in a heat exchanger to pre heat BFW then less fuel is required ,to get to critical or super critcal steam pressures in the infeed to the steam turbine .
A typical modern steam turbine will use around 50% of the steam energy which is usually condensed and fed back in to the boiler , although many large boilers to steam turbines use re heat sections . A typical solid fuel boiler will convert around 80% of the fuel energy to steam and around 50% of that steam energy gets converted into KW , hence why some of the old power stations are at 30% conversion of KJ to KW and even the most modern ones not using CHP cant yet reach 45% conversion . when you use CHP it gets to around 60% , however I believe my design will give an fuel to KW conversion of over 55% , as I can get much better heat recovery using a co fired (CH4 and solid fuel) oxy fuel system .
