Abstract
The author studied the dynamic characteristics of slab heating in the furnace under the considerations of fuel consumption and combustion gas flow characteristics through furnace.
In the analysis of
1. dynamics of heat transfer from combustion gas to slab,
2. dynamics of heat transfer in furnace,
3. dynamics of heat transfer in furnace with recuperator,
the factors which must be considered in the dynamical characteristics of the furnace were so chosen that the existent furnace can be operated in these manners, and these assumptions were so simplified that the analytical procedures go on easily.
