The invention discloses combustion furnace equipment. The combustion furnace equipment comprises a combustion unit, a cooling unit, an exhaust unit and a water supply unit. The combustion unit comprises a combustion furnace; and the cooling unit comprises a shell, a first cooling set, a second cooling set, a liquid storage chamber, a gas collecting chamber and a conveying pipe. The first cooling set comprises multiple first pipe bodies and multiple first separation plates; and the first separation plates are provided with intake ports connected and communicating with the conveying pipe. The second cooling set comprises multiple second pipe bodies and multiple second separation plates, wherein the second separation plates are provided with exhaust ports. Hot air generated by combustion of objects in the combustion furnace is conveyed to the cooling units by the conveying pipe to contact with each first pipe body and each second pipe body to heat liquid, so that the liquid forms steam; and then, the steam is applied to multiple places to effectively reduce the energy waste. In addition, the intake ports and the exhaust ports are arranged near the liquid storage chamber, so that the cooling effect on the hot air is effectively improved.
