| Abstract Scope |
A hydrogen rich model for a blast furnace has been established, based on the theory of thermal and mass balance in blast furnace. The operating range for injecting coalbed methane and pulverized coal into the blast furnace tuyere has been determined, with the raceway adiabatic flame temperature and the top gas temperature as limiting conditions, providing guidance for high-yield and low consumption operation of the blast furnace. The study has shown that as the oxygen content in the blast increases, the raceway adiabatic flame temperature also increases, which means that more coalbed methane can be injected and the carbon input to the blast furnace decreases, but the temperature of the top gas also decreases. When only coalbed methane is injected into the blast furnace tuyere, the blast furnace can accept a significant increase in coalbed methane injection volume, but the coke rate is higher than that of traditional blast furnaces. |
