Description

For the recovery boiler, it is preferable that black liquor is as high dry solids as possible, but the higher dry solids, the higher viscosity of black liquor and brings some problems such as plugging issue or unstable operation. In order to solve these problems, and to decrease power consumption, we had changed to dissolve the dust into 55% solids black liquor instead of heavy black liquor. As a result of it, we can keep the heating surface area more cleanly in the vacuum evaporator as well as energy saving in the black liquor process. In addition, dry solids of heavy black liquor has been improved.
