   Heavy oil incinerator, gas incinerator and dual fuel incinerator (light oil / gas or heavy oil / gas). According to the operation and operation mode, orette incinerator is divided into one-stage, two-stage, progressive two-stage and progressive two-stage with share regulator (the latter implements share regulation operation).

   Industrial incinerator series: all high-power incinerators are specially planned for special industrial use. According to the classification of NOx reduction incineration skills, the incinerator is an important equipment on industrial oil fired boilers and gas-fired boilers. It ensures the safe ignition and complete incineration of fuel.

   Therefore, in order to control the generation of NOx, we must start from the incinerator. According to the incineration skills of reducing NOx, the low NOx incinerators are roughly divided into the following categories: the stage incinerator is a stage incinerator planned according to the principle of graded incineration, which makes the fuel and air burn in sections. Because the incineration violates the theoretical equivalence ratio, it can reduce the generation of NOx.

   One is to use the pressure head of combustion supporting air to suck back part of the incineration flue gas, enter the incinerator and mix it with air for incineration. Because of flue gas recirculation, the heat capacity of incineration flue gas is large, the incineration temperature decreases and NOx decreases. Another self recycling incinerator is to recycle part of the flue gas directly in the incinerator and join the incineration process. This incinerator has the dual effects of restraining nitrogen oxide and saving energy.
