Title:
APPARATUS AND METHOD CAPABLE OF MONITORING AND ADJUSTING IN-FURNACE COMBUSTION CONDITION IN REAL TIME
Document Type and Number:
WIPO Patent Application WO/2021/129564
Kind Code:
A1
Abstract:
An apparatus capable of monitoring and adjusting an in-furnace combustion condition in real time, comprising: a furnace having a heating chamber (1), a combustor (2), a charging door (3), an exhaust gas flow port (4), and an exhaust gas flow pipe (5), wherein the combustor (2) is used for introducing fuel and/or an oxygen-containing gas into the heating chamber (1) to form a flame, the charging door (3) is used for adding a raw material, and the gas generated by combustion in the heating chamber (1) enters the exhaust gas flow pipe (5) through the exhaust gas flow port (4); two sensors (20, 21) of the same type arranged at different positions in the exhaust gas flow pipe (5); and a control device (30) receiving signals of the two sensors (20, 21) and adjusting, according to a difference between the signals, the amount of the fuel and/or the oxygen-containing gas entering the combustor (2). The first sensor (20) is provided proximate to the exhaust gas flow port (4), and the second sensor (21) is provided at a position 5-10 meters downstream from the first sensor. A flame sensor, a temperature sensor, a pressure sensor, an oxygen concentration sensor, a carbon monoxide concentration sensor, or a carbon dioxide concentration sensor can be selected as the two sensors (20, 21).
