Glass kiln combustion optimization and flue gas analysis and evaluation method

Abstract

The invention relates to the field of glass kiln combustion energy conservation and waste heat utilization, in particular to a glass kiln combustion optimization and flue gas analysis evaluation method, which comprises a kiln, the kiln comprises a heat storage chamber, a small furnace, a branch flue and a main flue, and further comprises a DCS system, an on-line flue gas analyzer and a detection unit, the DCS system is electrically connected with the on-line flue gas analyzer, and the on-line flue gas analyzer is electrically connected with the detection unit. The on-line flue gas analyzer is electrically connected with a plurality of detection units, the plurality of detection units are respectively arranged in a heat storage chamber, a branch flue and a main flue, and the on-line flue gas analyzer receives flue gas data of the detection units and transmits the flue gas data to a DCS (Distributed Control System) in the form of a digital signal. The combustion state of the small furnaces is optimized by collecting the flue gas data of the upper part of the heat storage chamber in real time, calculating the air / fuel ratio of each small furnace and accurately adjusting the combustion air amount in combination with the DCS, so that the combustion efficiency is improved, and the fuel waste is reduced.
