Abstract

The invention discloses a glass melting furnace flue gas waste heat recycling system and method in the technical field of glass melting furnace flue gas treatment. The glass melting furnace flue gas waste heat recycling system comprises a glass melting furnace; a high-temperature flue gas inlet of the waste heat boiler is communicated with a smoke outlet of the glass melting furnace through a connecting pipeline; a combustion-supporting air outlet of the combustion-supporting air device is communicated with the heat storage chamber of the glass melting furnace; the air outlet end of the air inducing pipe is communicated with the combustion-supporting air inlet of the combustion-supporting air device; and the heat exchanger is arranged on the air inducing pipe and communicates with a low-temperature flue gas outlet of the waste heat boiler. The low-temperature flue gas exhausted by the waste heat boiler and the combustion-supporting air entering the air inducing pipe are subjected to heat exchange through the heat exchanger, the temperature of the flue gas exhausted into the air is reduced, the temperature of the combustion-supporting air is increased to 60-150 DEG C, the problem of waste of waste heat of the low-temperature flue gas is solved, fuel can be saved by about 5%, and the effect of saving energy is achieved.

Description

technical field [0001] The invention relates to the technical field of glass melting furnace flue gas treatment, in particular to a system and method for recovering and utilizing waste heat of glass melting furnace flue gas. Background technique [0002] Glass melting furnace refers to thermal equipment used for melting glass batch materials in glass manufacturing. It is used to melt, clarify and form powder and clinker (cullet) prepared according to glass composition at high temperature in the kiln. Glass liquid that meets molding requirements. In industrially developed countries, the thermal efficiency of glass melting furnaces is generally 30%-40%, while the average thermal efficiency of glass melting furnaces in my country is only 20%-30%. The exhaust heat of the heat chamber accounts for the largest proportion. Generally, the temperature of the flue gas discharged from the regenerator is 500°C to 600°C, and the temperature of the flue gas discharged from the all-oxygen ...
