Full premix Steam generator The tubular full premixed combustion system is mainly adopted. Before entering the combustion chamber, the gas and air are proportioned and fully mixed by fans, gas valves and mixers, and then fully burned on the surface of the metal fiber burner. With a small air excess coefficient, the combustion is more complete, the thermal efficiency is higher, and the CO emission is low. In addition, The flame of the metal fiber burner is short and uniform, without the local high temperature zone of the traditional jet burner. At the same time, the strength of the fire hole is low, and the resulting NOx is significantly reduced.

All steam generators can achieve ultra-low nitrogen emissions. Steam generators that can achieve ultra-low nitrogen emissions have their own core technologies. With the help of technology, they can achieve ultra-low nitrogen emissions from steam generators.

The fully premixed steam generator adopts the fully premixed laminar flow design, and is equipped with high-quality combustion valve group, fan and combustion head. Before entering the combustion chamber, the gas is fully premixed with air in the combustion valve group.

Fully premixed steam generator When working, the metal fiber combustion head is not in the local high temperature zone of the traditional jet burner, but is replaced by a short and uniform blue flame. At the same time, the combustion intensity of the fire hole is low, and the resulting nitrogen oxides are also significantly reduced.

The fully premixed laminar steam generator also uses the flue gas recirculation combustion technology. By reintroducing part of the flue gas from the fully premixed steam generator into the combustion chamber, and mixing with gas and air for re combustion, the flue gas recirculation technology is used to reduce the combustion temperature in the core area of the steam generator. Under the condition that the excess air coefficient remains unchanged and the efficiency of the steam generator does not decrease, It inhibits the formation of nitrogen oxides and reduces the emission of nitrogen oxides.
