Yet another improvement to my old Franko Belge Lorraine multi-fuel stove / log burner that has enabled cleaner combustion and more fuel savings. See images for drilled stainless tubing.
See last 7 images. Now, thanks to a suggestion in the comments, a further modification was installed, which involved drilling the existing upper stainless "3/4 inch pipe and adding an additional length of stainless steel threaded tubing, coupled with a 3/4" socket and capped off with a 3/4" threaded end cap.
This helped to spread the air intake across the width of the fire and also increased the temperature of the gas and air mixture, generating a whiter flame, even cleaner combustion, evident in the glass doors. Since the latest modification with extended drilled stainless steel tube as suggested by Gardenweld, the infra red thermometer has recorded temperatures off the scale of 400 degrees Centigrade. The fire was so hot it caused the water to kettle inside because the water pump was not running fast enough. Have now increased speed of pump and it has cooled the fire down better and boosted the radiator and hot water supply.
We have plenty of free hot water and our home is heated burning scrap wood, mostly pine and if we are lucky some hard woods.
Our gas bill for the winter quarter is now a staggering £15.00 for 3 months of blissful free hot water and a cosy warm home. Yes you read that right. By opting for a non-standing charge tariff we have not only virtually eliminated our heating bill, but we now have an almost smoke free combustion in our wood burner. No more creosote and less chimney sweeping.
