The tilting-type burners commonly used in large boilers with tangential corner firing to regulate the reheater steam temperature have many advantages

such as large range of temperature regulation

sensitivity of adjustment

simple structure

without the necessity to increase the additional heat surface and the power consumption etc

hence the said burners have enjoyed extensive application. But

partial overtemperature of the reheater can be caused by slagging in the furnace in the process of operation. When tilting down burners are used to regulate the reheater temperature

excessive tilting-down angle may lead the flame to dash into the bottom ash hopper

resulting in clinker formation within the hopper

initiating severe accident of clinkering. Therefore

the ash and clinker deposition performance in the bottom ash hopper under different conditions of burner tilting

including burner in horizontal position

burner evenly and unevenly tilting down

as well as ash and clinker deposition having occurred in the bottom ash hopper

has been studied. The results obtained have certain reference value for design and operation of tilting-type burners.
