Embodiment Construction

[0036] FIG. 1 shows schematically and partially a combustion air preheating plant 100 . Here, instead of conventional preheating chambers, granular material regenerators 1 , 2 , 3 are used. The bulk material regenerators 1, 2, 3 pass through the pipeline system 30 and the flue gas supply device 10 for hot flue gas, the fresh gas supply device 12 for cold fresh air, the flue gas discharge device 14 for cold flue gas, and after preheating The fresh gas discharge device 16 of the combustion air is connected to the flue gas branch flow 18 . The working air supply device 20 supplies compressed air for the return pipes 34a, 34b and 34c. The main task of the combustion air preheating device 100 is to draw in cold air via the fresh gas supply device 12 and to supply the preheated combustion air to the combustion process via the fresh gas discharge device 16 .

[0037] Starting from the periodic alternating operation of the three granular material heat accumulators 1 , 2 , 3 , the fi...

Abstract

The invention discloses a method for optimizing the combustion process of a furnace, in particular for melting raw materials, in the production of glass, wherein at least one particulate material of flue gas (10) and / or fresh gas (12) is used for preheating the combustion air. Heat accumulators (1, 2, 3), of which two granular material heat accumulators (1, 2) work alternately during the heat exchange process, and the flue gas (10) passes through the first stage of the absorption operation (B). The granular material regenerator (1) flows, and the fresh gas (12) flows through the second granular material regenerator (2) in discharge operation (E). According to the invention, the third granular material regenerator (3) in standby mode (W) can be switched on to conduct the flue gases and fresh gases (10, 12), thereby optimizing the combustion air temperature. Temperature change characteristics.

Description

technical field [0001] The present invention belongs to the field of the glass industry. [0002] The invention relates to a method for optimizing the combustion process in a furnace, in particular for melting raw materials, in which at least one flue gas and / or fresh gas regenerator or heat exchanger is used for preheating the combustion air , in which the two bulk material regenerators work alternately during the heat exchange process, the flue gas flows through the first bulk material heat accumulator in the absorption operation, and the fresh gas flows through the second bulk material regenerator in the discharge operation Accumulator flow. Background technique [0003] In the glass industry, high energy consumption is required for melting the raw materials for glass production. In order to reduce primary energy consumption or primary energy consumption, preheat the required combustion air. To achieve the necessary temperatures of up to 1650° C., the bath is heated wi...
