stopwatch

I am trying to spec out some parts. Do you think a regulator is required for residential NG it just a flow control valve. It's already at .5 psi anyway, it's more about volume isn't it. I'm thinking: NG connection -> ball valve -> solenoid valve -> flow valve (needle?) -> orifice into mixing chamber Any issue with this line of thought?? Thanks again.

Seems simple enough I suppose. I took a quick look for the book and it appears to no longer be in print. Amazon has informed me I could buy a used one for $440 which may not be worth it. I'll keep looking. Any recommendations on fan sizing?

Thanks for the responses guys. I will pick up the book to read. When you say you are 75 feet from the pipe line, do you mean the main line or from your home's meter. I'm assuming you don't have a seperate meter for your forge line. Also the book might go over this but what type of a safety system do you have on your NG forge. Is there any mechanism that is necessary? Just curious about your set up. What commercial burner do you use as I am not opposed to buying although I like the concept of building so that I understand the forge better.

Hello everyone. I am new to the hobby and looking to set up my first forge. I have natural gas plumbed to my house and I am hoping to use that rather than LP. That being said, through reading the forums, I know that my house likely runs at very low pressure (0.5 psi or less) and I will have to at the very least have the following things: -A blower since the low pressure cannot create the flow required for naturally aspirated -A longer run of piping after the nozzle as NG mixes slower than LP -I should at the very least have an auto solenoid to shut off gas on loss of power (beyond the manual shut off and regulator) I read through the design considerations on Wayne coes website and his ribbon burner simply talks about a mixing chamber where fuel is injected. Can I still just use a mig tip nozzle in a design similar to the Wayne Coe example? Can you run at such low psi? I will have to call to find out exactly pressures. I have seen posts mentioning success with an NG set up, but never in the detail of Mikey or Frosty. I had no luck with the search feature. I have found that NG is clearly not the favorite gas so there are fewer specifics available. I apologize for the wordy post. Thanks for any help.
