Lasse Ballweg Posted November 22, 2019 Share Posted November 22, 2019 Hey guys, I'm new to the forum so I'll introduce myself, I'm Lasse a 19 year old blacksmith and tinkerer from northern Germany. I built my ribbon burner and I'm trying to tune it in now. First of all my blower is probably too weak right? It's just a tiny hair dryer but I'll get a new one with speed control soon. And I can't turn down my gas really low it's going down to 0,5bars and then it's blowing the burner out. And I also have a good 3' of dragons breath. Currently I have a 1.5mm hole as an gas intake. I'm happy for any advice Quote Link to comment Share on other sites More sharing options...
Buzzkill Posted November 22, 2019 Share Posted November 22, 2019 You need to be able to adjust both the air and gas supplies independently in fairly small increments. A needle valve on the gas side will help and a valve or a bypass system on the air side will do. You should not expect a one speed blower or a 2 speed hair dryer to be sufficient for controlling the air flow without some other means of fine tuning it. My preference for controlling the air flow is a gate valve, but there are many options that will work. Quote Link to comment Share on other sites More sharing options...
Lasse Ballweg Posted November 22, 2019 Author Share Posted November 22, 2019 Thanks Buzzkill! I'll order a variable speed blower now. I think that will be okay and I'll get a needle valve for the gas too Quote Link to comment Share on other sites More sharing options...

Mr Moose Posted January 18, 2020 Share Posted January 18, 2020 I agree with Buzzkill about the gate valve for air control. I have a speed control on me setup and I found that this is not enough. Needed less air. Added a shutter to the blower inlet and it was not enough. Added a gate valve to the air inlet at the burner tube and that finally gave me the control I needed over the air flow. A shutter on the blower intake will lower the load on the blower motor. A gate valve would be were I would start. Cheap and easy. Quote Link to comment Share on other sites More sharing options...
