Combustion process of glass kiln with non-catalytic converter

Abstract

The invention discloses a combustion process of a glass kiln with a non-catalytic converter. A required system comprises a glass kiln, a non-catalytic converter A / B, a flue gas recovery device, a chimney, a high-temperature flue gas fan, a natural gas supply device and an oxygen supply device. According to the invention, part of the flue gas of the glass kiln is circulated, the concentration of water vapor and carbon dioxide in the circulating flue gas is increased, the water vapor and carbon dioxide in the circulating flue gas and natural gas are subjected to conversion and reforming reaction in the non-catalytic converter, the sensible heat of the high-temperature flue gas is recovered, and meanwhile, the high-calorific-value water gas of 1300 DEG C or above is generated, so that the total calorific value and the charging temperature of the gas entering the glass kiln are improved, the high-calorific-value water gas, a small amount of unreacted natural gas and oxygen are fully combusted in the glass kiln, the fuel consumption is reduced, and the heat recovery efficiency is improved. The combustion process has excellent performance in the aspects of yield increase, energy conservation and emission reduction, the unit heat consumption and the comprehensive energy consumption can be reduced, the yield is increased, the smoke emission is reduced, and ultralow emission of NOx is achieved.

Description

technical field [0001] The invention relates to the technical field of glass kiln combustion, in particular to a glass kiln combustion process with a non-catalytic conversion furnace. Background technique [0002] As global warming touches various aspects such as ecological security, water resource security, and food security, it intensifies the risk of extreme climate disasters and seriously threatens the living environment of human beings. The emission of greenhouse gases is the most important factor causing global warming, and the greenhouse effect produced by carbon dioxide accounts for more than 70% of all greenhouse gases. Therefore, the reduction of carbon dioxide emissions is an urgent problem to be solved. Warmth is crucial. [0003] With the imbalance of global energy supply and the aggravation of geopolitical crisis, fuel prices continue to rise, and the cost of glass production is getting higher and higher. At the same time, the requirements for energy saving an...
