Comments

Burners mix combustive air and fuel (heavy fuel oil, diesel oil, coal or liquefied gas); Quality of this mix is a function of several factors such as viscosity of fuel, pulverizing pressure and temperaturer. Techniques exist to improve the mix such as the steam assisted pulverizing, rotary spin atomizer, the electric consumption of the combustive air fan can be reduced by using an variation speed drive motor ( VSD)
