TH11890EX - Burners for solid and liquid fuels or gases - Google Patents

Abstract

Burners (1) for feeding solid and liquid fuels or gases into the combustion area (8) of a furnace, such as a rotary kiln. And which consist of a central rail (2) for feeding liquid fuel or gas, a common rail (3) for primary air and a common rail (4) for solid fuel is provided with a rail (5) for feeding a certain amount of primary air. Into the combustion zone (8), the primary air feed rail (5) is in the form of a heat exchanger for transferring heat from the interior Of the furnace that surrounds the combustion burner (1) to the primary air at Is transmitted in the rail system (5) and hence increases the speed of Air passing through the rail system without Increase the fan power or the energy consumption of the furnace plant, but with a definite decrease in the primary air intake being fed Burning area The primary air feed rail system (5) is separated from the rest of the burner by an insulating layer (7).
