In pulp mills, keeping the internal heat transfer surfaces of recovery boilers clean requires a lot of energy and can limit the entire mill’s production capacity. However, by reducing the amount of steam used in steam sootblowing systems, pulp mills and other plants can become more energy-efficient and sustainable, while improving boiler availability.

It is possible to significantly optimize the operations of recovery boilers in pulp mills simply by cleaning the soot off heat transfer surfaces in a more efficient way. We know, we’ve done the research. Here is what we discovered from our study of recovery boilers in Sweden.

High Impact Sootblowing System General Installation Procedure Below describes the measures necessary for the implementation of the High Impact Soot System (HISS), for the optimization of steam soot blower and recovery boiler operation.  Step 1 – Install pneumatic actuator on the steam soot blowers The installation takes approximately 10 – 15 min per blower and can be performed during boiler operation. The actuators can be bypassed with a blocking pin. Step 2 – Install pneumatic control boxes for HISS The actuators are operated with instrument air at ~6 bar and is distributed to the soot blowers, through pneumatic control boxes. Each control box can handle up to 12 soot blowers. Step 3 – Install ACABBM 800M controllers for the actuators The contactors for the soot blowers are replaced with new ones, with direction control. Furthermore, an ACABBM 800M controller is installed. This make up the controls for the HISS-function. Step 4 – Implementation of operator control display The soot blower [...]
