Dry quenching coke boiler with ash bin and dry quenching coke system

Abstract

The utility model embodiment provides a kind of dry quenching boiler of ash bin and dry quenching system, including first flue gas passage, second flue gas passage, expansion joint and economizer. First flue gas passage is located above second flue gas passage, and the both are connected by expansion joint, and the expansion joint is connected with the outlet of the bottom of first flue gas passage and the inlet of the top of second flue gas passage respectively. Economizer is set in second flue gas passage. Along first direction, second flue gas passage has opposite first side and second side, first side is provided with flue gas outlet, and second side bottom is provided with ash removal device. Ash removal device set in the bottom of second side of second flue gas passage can directly collect and discharge settled flocculi, reduce the accumulation amount of flocculi in second flue gas passage. Compared with prior art, the structure can conveniently and timely remove flocculi deposited in the bottom of second side of second flue gas passage, reduce the probability that flocculi block the heating surface passage of economizer, and further improve the operation stability of dry quenching system.
