Frequency gas burner used in today's industrial production is relatively high, which is why it makes the gas burner subject to certain sought after, then how low nitrogen gas boiler transformation?
How low nitrogen gas boiler transformation?
With the national energy restructuring and industrial upgrading, natural gas and other governments to promote the use of clean energy, low-nitrogen gas boiler renovation work began, then how low nitrogen gas boiler transformation? How low nitrogen gas boiler transformation? Transformation low nitrogen gas boiler has two forms: 1, flue gas recirculation transformation (Ultra Low NOx) a - is the use of species combustion air ram, the part of the combustion fumes sucked back into the combustor, mixed with the combustion air. Since the flue gas recirculation, the combustion fumes a large heat capacity, the combustion temperature is lowered, the NOx reduction. Another recirculation burner itself is directly recycled into the part of the fumes inside the burner and to the combustion process, the burner has such a suppression effect of nitric oxide and the double energy. 2, the premix burner (combustion surface) technology premix gas burner, the gas and air are thoroughly pre-mixed prior to entering the combustion chamber, so that more complete combustion, improve the combustion efficiency and reduce harmful emissions, but also can reduce the space requirements of the combustion chamber, is currently the most advanced of a - kind of gas combustion technology, this is the use of low nitrogen burners. How low nitrogen burners to reduce nitrogen emissions? To achieve ultra-low nitrogen oxide emissions within 30mg / m, it is difficult using a single technique difficult to achieve, while the use of two low NOx combustion technology is often easier to implement: 1) the circulation flue gas (FIR), NOx emissions can be low to 19mg / Nm & sup3; 2) using imported burner, reliable 3) Adaptive multi boiler, transformation, review 100% success rate 4) the combustor stable, safe, low maintenance costs 5) staged combustion technique, low while nitrogen is not reduced by more than boiler combustion efficiency gas boiler is how low the entire contents of nitrogen transformation, and the use of low nitrogen burners transformation to low-nitrogen gas boiler is a more effective way, there is a need, we can understand a lot.
