Description

technical field [0001] The present invention relates to an energy-saving and combustion-supporting system for all industrial furnace combustion systems through fuel combustion, which is suitable for various fuels, including natural gas, liquefied gas, coal gas, coal, coal powder, coal water slurry, heavy oil, diesel oil, kerosene, Residual oil, tar powder, etc. Background technique [0002] At present, various industrial furnaces in our country rely on ordinary air for combustion support. There is only 20.93% oxygen in the air, which is used to participate in combustion support, while nitrogen, which accounts for 78.10% in the air, not only cannot participate in combustion, but also takes away a lot of heat energy during the combustion process. , so that the current combustion system has high energy consumption, low efficiency, a large proportion of fuel consumption per unit product, and serious environmental pollution. With the energy crisis, the rising cost of raw materia...

Problems solved by technology

This technology is theoretically feasible, but there are great shortcomings in its practical application in industrial production, and it cannot even achieve the goal of energy saving in a long-term and stable manner. Specifically:

[0003] 1. The maximum concentration of oxygen produced by the membrane method oxygen production equipment is 28%-30% (imported membranes are up to 35%). This oxygen concentration has limitations in the application of energy saving and combustion support, and the concentration cannot be adjusted according to the conditions of different industrial furnaces, so that Failure to meet optimal energy saving targets;

[0004] 2. In reality, the working conditions and environment of enterprises with high energy consumption using industrial furnaces are not good, and the ambient air quality is not good. However, the working principle of membrane oxygen production requires clean and smooth intake air, which must pass through the air filter element. The unclean air makes the filter element easy to plug. Usually, the membrane equipment will not produce 28%-30% oxygen after several months of use, so the sustainability of the energy saving effect will not exist;

[0005] 3. Oxygen-enriched air produced by membrane oxygen production method determines the low pressure of its oxygen-enriched gas due to the oxygen production method of the membrane method, which greatly limits its range of energy-saving applications in industrial furnaces and different fuels.
