A burner block is a component of a refractory lining for kilns and other thermal generating units in which a burning devise is to be installed. Burner blocks are designed to provide stable heat insulation against the high-temperature of a burner flame and to ensure the required opening angle of a flame.
With the use of burner blocks preshaped in plant conditions, the complexity concerning the installation of a lining for a kiln or other thermal-generating units is diminished and the possibility to break the lining configuration is decreased. Due to the heat-insulation provided by burner blocks as well as specials refractory materials used for their manufacture, the durability of a lining is increased.
