Many customers inquire about the core difference between low-nitrogen combustion engine and ordinary internal combustion engine through our website, so today, the editor will explain the core difference between low-nitrogen combustion engine and ordinary internal combustion engine.
What is low nitrogen technology?
By combining low-nitrogen burner technology with other major measures, the efficiency of nitrogen removal can be effectively achieved. Boiler and burner technology uses heat to produce hot water and steam. During the combustion process, nitrous oxide (nitrogen) and nitrogen dioxide are produced as by-products. These pollutants can cause harmful reactions, leading to the production of acid rain and ozone.
Nitrogen oxides come from three main sources: 1. Hot nitrogen is the result of high-temperature combustion. Hot nitrogen is the primary contributor to overall nitrogen emissions; 2. It is suggested that nitrogen is the time when nitrogen is combined with fuel; 3. Fuel-combined nitrogen usually does not involve natural gas. Manufacturers of low nitrogen burners use low NOx deflection, air classification and flue gas circulation. The purpose of flue gas recirculation can be achieved by introducing the combustion products in the furnace into the flame or mixing the POC of the exhaust system with air or fuel to reduce the furnace temperature.
The functional effect of the low-nitrogen burner can produce high-temperature vortex of pulverized coal in a short time. It has the advantages of good combustion, high heat utilization, smoke and dust removal, improved working conditions, and reduced labor intensity. It is an ideal product for energy conservation and environmental protection. The pulverized coal burner is suitable for various annealing furnaces, metal heating furnaces, quenching furnaces, precision casting shell burning furnaces, melting furnaces, forging furnaces and other heating furnaces. Refers to equipment that can fully burn pulverized coal in a short time and generate high-temperature eddy currents.
Whether it is coal-fired or gas-fired boilers, the use of ultra-low nitrogen burners can save investment and operating costs. According to relevant national regulations, the nitrogen oxide emissions of newly-built boilers must be less than 30mg/m3, and the emissions of ultra-low nitrogen burners of gas-fired boilers used must be less than 80mg/m3. Then, we need ultra-low nitrogen burners to help us realize this plan. Many people mistakenly believe that only inhalable particles are the culprit of smoke. In fact, another reason for nitrogen oxides cannot be ignored.
Most of the new boilers that have been put into operation in recent years have been retrofitted with advanced ultra-low nitrogen burners. There is basically no room for modification, but NOx emissions can be optimized through combustion.
