Decomposing furnace based on multi-fuel injection technology
The invention discloses a decomposing furnace based on the multi-fuel injection technology. The decomposing furnace comprises a spouting furnace, a pre-swirl combustion chamber which is positioned below the spouting furnace and communicated with the spouting furnace, and a lower cone body which is positioned between the pre-swirl combustion chamber and communicated with the pre-swirl combustion chamber; a third air inlet and a main fuel injection pipe communicated with a cavity are arranged on the pre-swirl combustion chamber; an inlet of the main fuel injection pipe is formed in the sidewall of the pre-swirl combustion chamber; a secondary fuel injection pipe is positioned on the top part of the pre-swirl combustion chamber or positioned at the cone part of the spouting furnace or positioned on a column body of the spouting furnace; the distance from the main fuel injection pipe to the top end surface of the pre-swirl combustion chamber is A; the length of the short vertical side of the third air inlet is h; the length of the long vertical side of the third air inlet is H; A, h and H meet the relationship below: A is not less than h/4 and not greater than 3H/4. The decomposing furnace is high in fuel adaptability; a plurality of fuel of different types can be injected to gain high combustion burnout rate and meal calcining rate.
