Heat loss to the ground
Heat loss to the ground
(OP)
We are building an oven, 34 meters x 5.5 meters x 10 meters.
the temperature inside will be 80 C, outside 20 C.
The footprint of the oven is a rectangle 34 by 10 meters, I know how to calculate the heat loss on the walls, but have no idea on how much heat will go to the ground.
The floor is a concrete slab some 10 inches thick over dirt.
Thanks in advance for any help.

RE: Heat loss to the ground
To answer fully to your question it is necesary to know the thermal conductivity of the material using for the construction of the furnace. if it is known then the following formulla can be used to calculate the heat transfer through the wall.
(T2-T1)
Q = K*A* -------
L
where
Q - heat transfer
K - Thermal cond of the material
T1&T2 - inside / outside temp.
L - thickness of the wall
A - area of the wall.
Hope this will solve your problem.
