[Watercourse management]

Thanks bob,that makes sense as what I have read about them is you need a fair bit of diesel with wet wood to get them going.

Once the inner skip was sacrificed I wonder how long the concrete would last?

 

I once used this method to line a chimney. I used galvanised spiral tube down the stone flue and filled the gap with vermiculite concrete, the tube did corrode away, but the concrete remained.

 

A chimney lining is a pretty low temp application and not subject to abrasion. Cast linings are

 

The inside of an air burner is a tougher life, Sodium silicate would be a better adhesive and a high alumina content would be the order of the day for the refractory lining.

I built one with my last company it was the size of a 40cu yd skip and it weighed in at 14t for getting rid of waste it was the best thing I have ever seen we were loading it for 10hr per day for weeks on end with a 25t digger it payed for itself in the first week as there was no waste the only thing you got out of it was scrap iron it had a fan on it that was about 50hp diesel the temperatures this thing would generate were in excess of 2000 deg c that was as high as it could read before the thermocouple melted it was built on a frame and the refractory panels just sat in to it we used to use just normal scrap skips but they would melt in a couple of days if I remember you could only burn something like 18t per day on the license from sepa we were slightly over that:001_rolleyes:

Hole in the ground looks like the best option so far, is the air actually just blasted over the top or into it as well? must be some air going in as the fires on you tube are raging.
