For the purpose of satisfying the needs for more highly efficient combustion, less pollutive emission and lower initial investment, we have developed Nisseki Clean Burner, aiming at high energy efficiency, less nitrogen oxides emission and less soot emission in any type of heavy fuel oil or kerosene boilers. There are three merits by introducing Nisseki Clean Burmer as follows.
First merit is that this burner permits excess oxygen to be cut by 0.51. 0% without increasing soot emission and achieves 2040 ppm or 1020% reduction of NOx emission at the same level of excess oxygen. Because a vortex is formed around the spray plate by feeding oil into a steam jet from the opposite direction, and this consequently promotes the atomization of oil. This vortex-atomization system makes use of patents we have already got.
Second merit is that this burner makes it possible much higher turn-down ratio (130), which means the changeable range of combustion load, than that of conventional burners by combining characteristics of the vortex formation and the pressure control of the steam jet.
Third merit is that this burner is easily retrofitted to any type of heavy fuel oil or kerosene boilers. We have only to replace burner guns or tips without changing or fixing up furnaces. In addition, burners can be replaced while boilers are in operation.
Nisseki Clean Burner with these merits is highly well evaluated within a lot of customers and its total sales have been growing year by year.
