Is it necessary to add a soot blowing system to the waste heat boiler in dry quenching of coke?

In dry quenching coke waste heat boilers, since the furnace tubes are exposed to dust in the coke flue gas, it is indeed necessary to install a soot blowing system. This helps to prevent dust from accumulating on the outer walls of the furnace tubes, improves heat exchange efficiency, and ensures the proper operation and high thermal efficiency of the boiler. The soot blowing system can use steam or air for soot blowing, with the choice depending on the specific operating conditions and boiler design. The placement of ash removal holes in the economizer must take into account the convenience and efficiency of ash removal; they should generally be located at the lowest point of the economizer or in areas where more dust accumulates, to facilitate dust cleaning. The size, shape, and number of soot extraction holes should be determined based on the design of the economizer and the physical properties of the dust, in order to ensure effective soot removal and prevent dust buildup from affecting the proper operation of the economizer. .
