Electric Kiln to Gas Furnace?

I modify a broken electric kiln to run on propane. Normally it would take 6 to 8 hours to heat up, now it takes just minutes.

Hey Cody! These electric to gas kiln conversions are great- a little tip as someone who has used them almost daily for some years now as a potter. If you enlarge your burner ports slightly and mount the burners slightly outside the shell of the kiln, it will provide 2 benefits: firstly, it will provide you with greater control over the combustion atmosphere inside so you can achieve greater efficiencey/temperature. By putting a damper over the flue hole, you will be able to control how much secondary air is dragged into the burner ports by the flame and adjust the mixture. This also cools the burners and prevents the metal scaling away due to oxidation. Adding a squirrel cage blower to each burner also increases the output temperature by a few hundred degrees.

@jafinch78 3 ай бұрын

Will also aid in control of glaze reactions, so to better control if you want more of an oxidation or reduction burn and glaze coloring effects.

@AureliusR 3 ай бұрын

Hope Cody takes this constructive feedback into account! Where do you mount the squirrel cage blowers? It looked like the outer skin of the kiln was starting to discolour, possibly because of the extreme heat, so I'd imagine mounting the blowers anywhere near the inlet ports would quickly annihilate them. Do you use some sort of piping to direct the airflow in?

A broken coil can be repaired. I got an electric kiln for cheap because of the broken wires. I've bought thin Constantan wire, stretched the broken wire a little bit to get the wires to overlap, used file to get the oxide off and the wound the Constantan wire around the overlap to reconnect the wires again. Repaired 5 breaks this way. Works fine for nearly 10 years now. You have to take your time and wind then tight to get a good connection.

I'd think bare crimp connectors would work similarly, perhaps backing it up with either constantan or nichrome.

Very clear, very simple demonstration of the energy density of the chemical bond vs readily available electrical power. Most folks do not TRULY appreciate just how many joules of energy it takes to do something and how that equates to electricity. 1 kwh - 3.6 x 10E6 joules. Standard cubic foot of natural gas (SCF) = 1.1x10E6

@moglbym_dyskutowac_z_psem 3 ай бұрын

It is a propane burner, so it looks even better, with 2.6×10E6 J per SCF. However, you have to mix it with around 24 SCF of air to burn it effectively, resulting in the release of a substantial amount of heat. You get hundreds of times more combustion products than substrate, and you have to dilute the combustible in the oxidizer. Moreover, one of the byproducts of propane combustion is water, which possesses a significant specific heat capacity, stealing a considerable amount of energy from the kiln in the form of steam. I am curious about the efficiency of this furnace and would bet it won't be more than 20%. Additionally, there are other differences; a gas-operated furnace will create a more reducing atmosphere than an electric one, typically intensifying oxidation. Furthermore, with gas, you give up easy temperature control. There is a lot of energy in chemical bonds but it is difficult to use it effectively.

Very nice conversion. You could probably cook a frozen turkey in 4 minutes ( or cause a steam explosion). If you line the inside walls with Kaowool Ceramic Fiber Insulation , your hard refractory will last longer. The refractory in electric units tend to be soft and brittle, very porous. I use 1” thick on my furnace and change it every year. It also mitigates any splashing and splattering from eroding the hard refractory of the furnace. Keep up the good work. Chicken Hole Base is coming along nicely too.

I mean, assuming he dials in the amount of gas flow needed to reach a certain temperature, it could end up being less gas than the old furnace would use for an equivalent task. Since less heat will be lost out the top if the metal takes less time to melt.

I don't know about forges or furnaces but I have some experience with home built gas kilns for pottery. I wouldn't put the burner inside the kiln. My burners are about one inch from the outside wall. I think it helps to increase the lifetime of the burners. I'm using natural draft burners so they also get some additional air like that. Also the hole for the burners are a bit larger than the burner itself. The burners allow to adjust the amount of air going in. That and adjusting the cross section of the chimney helps to control combustion and hopefully make it efficient. Just saw others already commented the same thing.

Just converting to natural gas a couple years ago dropped my electrical bill from =>400/month in the winter months to +-80/month with the additional ~120/month gas cost.. with the increase this year the last electric bill was at 132 which is clearly over the 18% it's supposed to be. Anyone else in different places experiencing large electrical increases?
