In the position of the' 10 furnaces in which heat is generated in any fire-box a indicated by full lines at Figure 1, convenient manner, and adapted to be varied the said box is at the limit of its movement in position relatively to the oven or to the to the right at which position the heating tubes employed for the transmission to the is concentrated, on the tube group 0.
