Title:
THREE-PHASE COMBINED HEAT SUPPLY TYPE LOW-CARBON SINTERING EQUIPMENT AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/130753
Kind Code:
A1
Abstract:
Three-phase combined heat supply type low-carbon sintering equipment, characterized in that: the equipment comprises a sintering machine trolley (1), a bottom fuel gas injection system (2), and heating sources; the bottom fuel gas injection system (2) is arranged below the sintering machine trolley (1); along the running direction of the sintering machine trolley (1), the heating sources are arranged on side portions of the sintering machine trolley (1). On the basis of currently using solid fuel to provide heat needed for sintering, fuel gas injection heat supply and heating source ignition heat supply are also introduced, and three-phase combined heat supply by solid fuel, fuel gas and heating sources is achieved; thus, the function of adding solid fuel into a sintering material layer in the prior art is gradually replaced by ignition of heating sources and heat release of fuel gas combustion, so that "low-carbon sintering" having a less coke ratio can be implemented.
