Question

A 2m x 2m x 2m furnace is made out of 10mm mild steel. It is aligned with 100mm fire brick clay. What is the heat storage of the complete furnace if the inside of the furnace is 1650°C? Make assumptions on required information.

A furnace of cubical shape, with external dimensions of .35 m, is constructed from a refractory brick (fireclay). If the wall thickness is 50mm, the inner surface temperature is 600 C, and the outer surface temperature is 75 C, calculate the heat loss from the furnace? Show where and how you get your k value.

A rectangular furnace with inside dimensions 0f 1.0 X 1.0 X 2.0 m has a wall thickness 0f 0.20 m. The k of the walls is 0.95 W/m.K. The inside of the furnace held at 800 K and the outside at 350 K. Calculate the total heat loss from the furnace.

00:01 Calculate the heat loss from the furnace.
00:03 Now our heat rate in terms of our shape factor q is equal to sk times our change in temperature.
00:10 Here k is 1 .1 watts per meters kelvin and our t, our temperature is the addition of these divided by two so that's 337 .5 degrees celsius.
00:26 Now our shape factor for a plain wall is just our area over length.
00:30 So we multiply 0 .25 times 0 .25 divided by 0 .05...
