Hi tony have to make one for a boiler I have do you have any more details on how you did the gas jetHi,
very nice would like to know more about the burner
The burner was designed many years ago and a lot have been made. They are designed to work in a quite small tube in this case the flue tube has an ID of 13.5mm (large1/2") the OD of the poker with mesh atached is about 8mm so there isn't much of a combustion space. So the flame needs to be low in height and preferrable wide. The burner itself is designed to have interchangable pokers that can have different numbers of slots of different shapes. The burner will work if necessary with no secondary air or it can be put under a pot boiler. As I make mostly model railway steam locomotives the plug of the burners being built will have a flame viewing hole drilled in the plug. This done because being slightly deaf and operating in often noisy exhibitions it is with the aid of a dental mirror to see if the flame on the burner is lit. Once the gas/air mix is correct it is possible to change pokers for different boilers this often done with my test burner shown up until now in the photographs. This test rig is used to check out locomotives when they are nearly finished without the compllcation of using their own gas burner systems. Or if it is a new design what type of burner will be needed. Now as it has been seen it was used to help design a burner. I hope to describe the construction of the remaining parts of the burner in this thread. If anything so far described isn't clear please ask.
