Heat and power production

We have a strong power generation offering that includes fluidized bed boilers, biomass gasifiers, integrated pyrolysisequipment for environmental protection and a wide selection of life-cycle services. Our expertise covers everything from fuel to stack. Around the world, we have more than 260 fluidized bed boiler references based on BFB (bubbling fluidized bed) and CFB (circulating fluidized bed) technologies.

Fluidized bed boilers can burn essentially all rejects coming from the mill, such as bark and other wood waste, sludge, de-inking rejects, and more. Typically, the energy demand is balanced with fuels – any solid fuels – purchased from the outside.

Biomass can also be utilized in a gasifier to produce biogas for a lime kiln and to replace the fossil fuels it uses. Another alternative in using biomass is integrated pyrolysis to produce bio-oil, which can be used in a lime kiln or sold onwards. An integrated pyrolyzer is always connected to a fluidized bed boiler.

Valmet BFB Boiler

Our solution utilizing bubbling fluidized bed (BFB) combustion technology has wide fuel flexibility, high combustion efficiency, high reliability, excellent controllability and low emissions.

Valmet CFB Boiler

Valmet CFB Boiler is an advanced circulating fluidized bed (CFB) boiler developed by Valmet. It combines high-efficiency combustion of various solid fuels with low emissions, even when burning fuels with completely different calorific values at the same time.


As a global leader in CFB gasification technologies and services, Valmet offers gasification solutions to meet the needs of various power and process industry sectors. Each of these solutions generates energy from biomass and waste with high overall efficiency.


The fast pyrolysis process results bio-oil which can replace heavy fuel oil.
