Abstract

The invention discloses a method for determination of reversal time of a sheet glass melting furnace. The method is characterized in that when a sheet glass melting furnace first-side regenerative chamber temperature detected by a thermocouple temperature-measurement probe reaches to the highest point, first-side reversal timing is started and reversal to a second side is carried out automatically; when a second temperature detected by a thermocouple temperature-measurement probe reaches to the highest point, first-side timing is stopped and second-side reversal timing is started and reversal to a first side is carried out automatically; and when the first-side temperature reaches to the highest point again, second-side timing is stopped so that a cycle is finished. The method has the advantages that the two thermocouple temperature-measurement probes are arranged respectively at regenerative chambers at the two sides and are used for measuring regenerative chamber temperature high points so that reversal time can be determined accurately and sheet glass melting furnace reversal can be controlled accurately and energy saving effects are improved.

Description

Technical field [0001] The invention relates to a method for changing fire in a plate glass melting furnace, in particular to a method for determining the fire changing time of a plate glass melting furnace. Background technique [0002] The melting furnace is the most critical equipment for the production of flat glass, which is used for the melting of glass raw materials; the current flat glass melting furnace is composed of a melting part, a cooling part, a regenerator and a flue. The two side walls of the melting part are equipped with There are two combustion spray guns and two regenerators. The two sides of the melting part are symmetrically divided. The chimneys are respectively connected through their respective flues. The two flues are each equipped with flue gates. The flue gates can be switched to connect to the air or the chimney. Flat glass The fundamental purpose of setting up a regenerator in a melting furnace is to save energy. [0003] The top and bottom of the re...
