I'm very sorry if i have upset you Baz (or anyone else), i'm just here to learn like everyone else.
Not sure what a Naptha Engine is Baz but i'll go and have a google.
The link i posted previously is to my channel, on my channel you will find lots of information which will shows you how to build the BioGen. I have provided frequent updates on the project in the form of videos and they are all in the uploads section. If you so wish you may then purchase a copy of the manual to support further development in the project. My BioGen website is simply intended to give those people who are interested and would like to help an opportunity to do so. I will not be making profit from selling a few manuals at 3.99 mate, but it will help.
The website is a place for people to acknowledge that building projects ain't cheap, so if they are interested in a project and would like to benefit from a project then maybe they could get involved in the project.
I hope more people have a go at a website of their own because i will (and have) bought manuals to projects i follow, it shows some respect for the amount of time and effort that person has put into their project instead of just expecting all their hard grafted for information for free.
I don't think our readers are gullible at all mate, that's why i'm posting here. I'm posting my idea in the relevant thread and hoping for intelligent people who share a similar interest to get involved or to inspire people to have a go.
Baz, the BioGen boiler in the video has got water inside. This will be replaced with Glycol so that i can run a higher temperature, prob around 120 degrees. But for now it is not worth spending my cash on glycol when 80 degrees will be enough to prove the concept.
The turbine is a scroll expander, they cope well will low rpm and low pressure high flow rates.
Could'nt find any info on the Davey Safety Engine Baz, i'm hoping you could post a link please?
My BioGen boiler is a prototype only, there will be improvements as materials become available, but the nature of the project is to build my system using recycled parts as and when they become available. That means i don't just go out and buy parts new because that is not sustainable. I'd love to come across a 3/4" stainless steel coil, but it ain't happened yet
As for the system needing constant supervision, then yes, until i have a working, leak free prototype organic rankine circuit using BUTANE!! i will not be firing the boiler at the same time. That is why there is a buffer (accumulator tank) attached to the boiler, it stores the energy so that it can then be used without the boiler firing in an alternating mode of operation, like this: Fire Boiler, Boiler Burns out, Use Hot water stored to generate electricity and then re fire the boiler when the water has gone cold. Each module is isolated from the other while testing.
Once i have completed the Electric Generation Module and i'm satisfied it is safe (leak free) i will run the two (Boiler and Electric Generation) together without any worry.
There is of course the possibility of using HFC 245fa as the working fluid in the turbine, this is non flammable, but again this is not available to me while i'm prototyping because i don't hold an F-Gas qualification. 245fa will come latter.
FIRST I MUST PROVE THE CONCEPT (using what is available ie, Butane).
