Papermaking sludgeis characterized by high volatile

high moisture content

low calorific value and high viscosity.A large amount of unhelpful water for combustion into the boiler

the flue gas moisture increase

dew-point rise caused low temperature corrosion of the heating surface of the tail. At the same time

papermaking sludge viscosity

in the transport is easy to produce bridge and blockage. In order to solve the above problems

high and low speed circulating fluidized bed boiler and boiler smoke exhaust are used to dry sludge quality and boiler heating surface layout

to avoid the tail heating surface low temperature corrosion. At the same time

the calorific value of sludge is improved

the sludge transport is unobstructed and the boiler combustion is stable. It is beneficial for sludge incineration to achieve the best effect

which can not only reduce the adverse impact of sludge on the environment

but also save a lot of energy consumption for paper making enterprises.
