[Lanny Henson]

Paul,
I will have more details about the burner in my 3rd video.
The burner is scalable. I use it in my 35 Gallon vat cooker.

>> 2.  Question/request:  Lanny, please provide more info about how your 
>> design does not have primary air entering below and therefore does not 
>> have a grate (if I understood correctly from the video).   And how is the

>> I am using a 40 qt  “sauce pot”  which is the same diameter as a 60 quart

>> Beyond 60 qt or liters I believe it is more practical to go with a

>> well, I believe better than a pot and a vat can be easily be made in shop 
>> for about the same cost or less than an aluminum pot which needs to be 6

>> My 35 gallon vat cooker cooks a 50 LB bag of rice with about 10 LB. of

>> Since it uses fairly large pieces of wood the remaining charcoal is large

>>> Many questions and comments, but just 2 here:
>>> 1.  Comment:  40 quarts are essentially 40 liters.  InStove has 60 liter 
>>> and 100 liter products.  There are also 200 liter and larger 
>>> institutional stoves.  How we as Stove designers address these size 
>>> issues will be a great discussion at Stove Camp (and on the Stove 
>>> Listserv.)

>>> To all:   THIS type of stove design and testing content is what the 
>>> Stoves Listserv is truly about.
