Title:
METHOD FOR CONTROLLING BLAST FURNACE TOP PRESSURE IN URGENCY STOP OF POWER GENERATOR USING TOP GAS PRESSURE OF BLAST FURNACE, AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JP2007182596
Kind Code:
A
Abstract:
To stably operate a blast furnace by suppressing the change of a furnace top pressure in an urgency stop of a power generator using a top gas pressure of a blast furnace.
In a facility which removes dust from a gas generated from the blast furnace 10 and makes a turbine 16 rotate by a clean gas to generate electricity, this control method includes temporarily stopping charging a raw material into the blast furnace when the power generator has emergently stopped, so as to suppress a synergistic change of a pressure change due to the urgency stop of the power generator and a pressure change due to the charge of the raw material.
