Valmet CFB Gasifier for biomass and waste

Gasification is Gasificationa rapidly developing combination of technologies and services for effectively converting biomass, recycled materials and waste into a usable form of energy. The CFB (circulating fluidized bed) gasification process works by partially combusting the biomass or waste at high temperatures using a controlled amount of air. The resulting product gas is a versatile energy carrier, which offers a range of benefits.

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.

Positive impact on environment

Reducing CO2 emissions is important – and doing it in an efficient and economically viable way is absolutely critical. From this perspective, gasification technologies are quite relevant as they enable partial or complete replacement of fossil fuels with renewable fuels.

Another advantage of waste gasification is that the process provides much better electrical efficiency compared with the direct combustion of waste materials. Also materials that would otherwise have been disposed of, such as unclean plastic, paper, cardboard and wood and other problematic waste, are used.

Easy boiler modification

It is easy to modify existing boilers or industrial kilns for the gasification process – even while leaving your existing fuel systems operational in parallel or for backup.

Modifying your operations for gasification creates a system that can accept many types of fuels. It can even be constructed on a scale of up to a several hundred MW unit size. What’s more, modifying an existing plant can extend its lifetime significantly.
