Read Moreboilers to recover 50 million tons of cooking chemicals as Na2O, and to produce 700 million tons of high pressure steam. This makes black liquor the fifth most important fuel in the world, next to coal, oil, natural gas, and gasoline [1]. Since black liquor is derived from wood, it is the most important renewable bio-fuel, particularly in
Read MoreANDRITZ PowerFluid boilers are based on Circulating Fluidized Bed (CFB) technology to produce steam and electricity from nearly all solid fuels from coal and biomass to alternative fuels and wastes.PowerFluid boilers employ proven, yet modern combustion technology to efficiently produce power while keeping emissions within environmentally safe limits.

Some condensing boiler manufacturers also claim that up to 98% thermal efficiency can be achieved with a condensing model when compared to the 70-80% achieved with typical designs. Other benefits of condensing boilers include
