insulation

What does anyone do for bioler insulation. I have a horizontal boiler that I fire with an open pan of methanol gell. the outside of the suporting case gets pretty hot
I have seen pics using string soaked in some kind of white powder. Is this french chalk. help

Hi Steam4,
 I can't answer your question but it would probably help with a photo of said steam engine, we like pics anyway and I have a hankering towards building a live paddle steamer at some point so am very interested in all things steam

What do you plan to put the steam engine into

When you get started it would be a good idea to do a build blog for us all to follow

Hi Steam4.


There are a few methods but as troutrunner comments, it's how you intend to use it and in what model, what erea, etc.


There must be photo's on the internet of the real boat you have in mind, so will get an idea what it is you want.


Do you just want to insulate your boiler or go for as near as possible to authenticity?


You say the casing gets very hot.
So is your boiler enclosed in an outer casing and you only want insulation between the two?


Paul's suggestion, yes photo's do speak volumes!
