mendodistilling Posted September 11, 2013 Share Posted September 11, 2013 Does anyone know where I can find something to diffuse heat from directly hitting the bottom of the kettle if I build a nice furnace heat box around the base of my kettles. I don't want the burners to bake on the beer wort that I'm going to be brewing and I'm afraid with the jet cooker intensity this is possible or probable. I have a still coming soon that has a nice ceramic diffuser plate that is shaped like a T but I've seen plate versions, I've seen a few different types and they just basically hit it and move outwards heating the air space rather than directly aiming a concentrated heat above it.

Dehner Distillery Posted September 12, 2013 Share Posted September 12, 2013 Goss I don't know what to say your going to have to realy shield around the sides so you don't lose all that heat. Maybe a wider burner than a jet cooker a use a perforated stainless screen with lava rock on top to diffuse it or ceramic material. Sounds like your going to lose efficiency.

mendodistilling Posted September 12, 2013 Author Share Posted September 12, 2013 I was going to make a Brick furnace, I'll be losing heat either way. I already considered that problem. I'm more worried about mallard affect on the beer wort. Link to comment Share on other sites More sharing options...
mendodistilling Posted September 12, 2013 Author Share Posted September 12, 2013 I'm actually worried about scorching it onto the bottom beyond easy removal. I have 110kbtu per bbl as a rule of thumb, the question is, will that direction under it cause scorching. I am worried if its not spread out it may be a problem. I did however find a manufacturer of the burners and it may be possible to have them help me from that standpoint. I also considered just using bendable lam wood and pouring a mould of concrete but I need to look into what to use. I know pizza ovens use specific stuff because of cracking issues from swelling when heated. I have seem prulho stills use fire brick which was my first idea. I was going to just set them on a forforklift able metal pallet and lay a slab on it and build it from there,. In the rare even that it needed to bemoved, it would be possible with ease.

Dehner Distillery Posted September 13, 2013 Share Posted September 13, 2013 Firebrick is made from refractory cement. You can buy it from some stores like a concrete plant. You need an agitator. I have so many Ideas for ya but I don't know witch one is the best fit. Link to comment Share on other sites More sharing options...
