Background
Boiler coking is a problem frequently encountered by power station boilers, and the occurrence and development of the boiler coking bring great harm to the safe operation of the boiler, and the boiler coking relates to the processes of coal quality, coal combustion, heat transfer, ash particle movement and the like. In the hearth of the pulverized coal boiler, ash in a molten or softened state is adhered to a heating surface to form accumulated ash, the temperature of the outer surface of the accumulated ash is increased due to poor heat conductivity of the ash, the roughness of the wall surface of the pipe is increased by accumulated ash, the ash in the softened state is easier to adhere, the temperature of the outer surface of ash is higher and higher, and thick coke slag is formed. The reason for coking mainly has several aspects, namely, the too high temperature of a hearth, the too low ash melting point and the untimely combustion adjustment.
In order to eliminate the hidden trouble, people can organize staff to perform continuous coking operation, generally, coke blocks in a furnace are knocked down by using coking rods with different lengths, but the temperature in a boiler is too high, so that the temperature of a coking opening is also correspondingly higher than the normal temperature, and the problem that smoke dust and the like in the furnace overflows outwards in the coking process, which can cause certain injury to the coking staff, so that a combined type boiler coking protection device is needed to solve the problem.
