Heating furnace soot blowing
Thread Content
In our unit, the soot blowing in the heating furnace is carried out by igniting a mixture of gas and air, which then causes an explosion that drives out the soot. However, I have a question: normally there is negative pressure inside the furnace, but why isn’t the gas and air removed during the time before ignition, once they are introduced into the soot blowing pipeline?
For the soot removal in heating furnaces with high fuel ash content, shock wave soot blowers prove to be effective; they are more energy-efficient than acoustic or steam-based methods.
