The instant invention relates to a burner holding device for burners, which is arranged on an entrained flow gasification reactor, wherein the burners (4, 5) are held in the burner holding device (7) and extend through a flange (11), which fixes the burner holding device (7) to the entrained flow gasification reactor (8) and extend through the burner holding device (7) into the entrained flow gasification reactor (8). The cooling device encompasses at least two cooling circuits (1, 2), which are independent from one another, wherein exactly one cooling circuit (1, 2) is at least partially assigned to each burner (4, 5), so that each burner (4, 5) is surrounded by a section of the cooling device on an-end facing the front surface and wherein at least one cooling circuit (1, 2) is at least partially assigned to the front surface for cooling. Below the flange (11) within the burner holding device (7) from top to bottom, a layer (19) consisting of insulating casting compound, which is fire resistant up to at least 800° C. and comprises a heat conductivity in the range of from 0.02-0.8 W/m K, a layer consisting of loose material (17), which is fire resistant up to at least 800° C., a layer (18) consisting of heat-conducting casting compound, which is fire resistant up to at least 1800° C. and comprises a heat conductivity of 3-15 W/m K furthermore surrounds the burners (4, 5).
