Definitions
- Figure 4 is a view corresponding to Figure 3 with respect to a furnace equipped with end-mounted furnace burners.
- regenerators 15 arranged along the sides of the furnace, these regenerators being shown schematically in Figures 2 and 3.
- the burners on one side-wall of the furnace are used alternately with the burners on the other side-wall, the hot combustion gases passing out through the openings 11 in the side-wall whose burners are at that moment inactive.
- the combustion gases function to heat the regenerators, the heat of which is subsequently used to pre-heat the combustion air when the burners on this side-wall of the furnace are activated.
- the booster burners 14 are directed slightly downwards onto the bath sur ⁇ face, suitable angles of inclination may be 0-30 * , preferably 10-20 * .
- the burners may also be directed slightly obliquely to the inlet end of the furnace.
