More Information
Summary:This invention relates to a front furnace calcium injection delivery system, which comprises bin, upper bucket, lower bucket, auger conveyor and fan, wherein the outlet of the lower bucket connects with the auger conveyor, and the discharge port of the auger conveyor connects with a vertical cut pipe through a level delivery pipe; the air outlet of the fan connects with one air pipe, and the other end of the air pipe connects with the inlet of the transporting material pipe; the lower end of the cut connects to the transporting material pipe, the auger conveyor is driven by the variable-frequency control motor which is connected with the frequency-changer electric. The control device comprises controlling machine, frequency-changer and sulfur dioxide density sensor, which can control the transporting quantity of limestone powder precisely; the auger conveyor can mix the limestone powder and high pressure draught evenly.
