Low nitrogen boiler transformation case

Boiler combustion flame from upper Cavallo split type low nitrogen burner jet, the inner layer of membrane type water wall tube furnace cooling, membrane water wall tube from the inner gas exports to fold into two layers of membrane type water wall tube of convective flue, then from the outer membrane type water wall tube gas exports back to by its and thermal insulation layer of lateral upper from boiler flue gas along the wall into the energy saving and condensate machine high temperature flue gas after the double condensation of economizer and condenser, the smoke discharged into the atmosphere.
