Change only the nozzle greater.

The first five burners in the first photograph, can run 5 miles from the socket

The advantage of naturally aspirated burner is that it does not need power. Burners operating with fans have the advantages of a lot more. I will mention here less gas consumption, adjustable flame atmosphere, the opportunity to work with a heating recuperative air supplied to the burner, absolutely safe operation without rolling back the flame to the burner. Such an image as the photograph is very common in my forge, sometimes it can not keep up with the production of burners. Demand for cooperating with ventilator burners is very high. None of the blacksmiths who once worked on the burners naturally aspirated, does not want to return to them.

It is the Soviet hammer. Information about it can find no problem at forum.ostmetal.info

Forum is in Polish. Aspirated burners are ineffective. I lost three years to experiment with burners to develop its own model of working with fans and giving full control of the flame atmosphere. They convinced them Polish blacksmiths, even those who could not imagine working at another hearth than Coke. My burners work in more than 200 forges, and it speaks for itself.

Vito, you write that you're from Slovenia, it may be easier for you to move Slavic blacksmith forum. We've got a lot of experience in the construction of gas furnaces, and is different from local. http://forumkowalskie.pl/viewtopic.php?t=76 Of course, we started from the burners naturally aspirated, but everyone still wants to have an effective and economical tool.

Your mistake is that we do not at this point arson burner. The burner ignites at the mouth of the flare, rather than at the outlet of the gas nozzle.

Yes you are right, the pressure gauge should be read in conjunction with the gas nozzle diameter. In my large burners I use jets of 1.2 millimeters and 1.0 millimeters smaller. The gas passing through the larger nozzle with a small pressure not cools as passing by a smaller die with high pressure. I did my first burner like so many on this forum atmospheric. 11 kg gas cylinder was sufficient for 8-9 hours. Burners currently used with recuperation and air blowing the same gas bottle is enough for 13 hours of operation with a large burner and 15 hours of operation with a small burner.

Under the floor of the furnace is integrated recuperator heats the air. Gas falling into the hot wind increases its volume, therefore, it need less. From here indication of the regulator close to zero. Heated is a nitrogen, which is 70% air. This results in an increase in the flame temperature. Forced airflow makes it possible to regulate the flame of reduction through neutral to oxidizing agent.

Urgently I am watching actions of new builders of gas hearths and with distress I state that they didn't break the certain stereotypes concerning the structure of burners. When I started my experiments with gas, I aspired for creating the strong, compact and economic burner. Over 200 burners made by me are heating iron up not only in Poland, but also also in England, Scotland, Germany, Portugal and Belarus. Many blacksmiths from Russia made also burners on the basis of observations of my burners. I will give a few links to films still for documentation where in stoves my burners are applied.https://www.youtube.com/watch?v=VvHDp1tscac https://www.youtube.com/watch?v=vDR_w0RCtTk https://www.youtube.com/watch?v=YWASmKTW_wk https://www.youtube.com/watch?v=QVrK00sVkC0

Many have seen the gas forge. I would like to show you forge., Which was established on Polish Forum Blacksmith as model
