The temperature in the combustion zone of a cement kiln varies between about 1370 to 1650 C (25OO to 5000 ⁰ F); this temperature is considerably lower than that of furnaces used for other purposes, such as the dead burning of dolomite. The problems encountered at the lower temperatures are different in nature from those encountered at the higher temperatures Attempts that have been made apply the teaching of cement separation technology to other areas, particularly dead burning of dolomite will not wax successfully.

A key feature of the invention is intensification a main air flame by supplying energy from a Outsource. When applying the invention to a Rotary kiln becomes the intensifying energy of a main flame by means of an additional oxygen fuel burner which is inserted into the furnace through the hood and is completely separate from the main burner system.
