Valmet Gasifier for biomass and waste

Valmet Gasifier, Vaskiluodon Voima Oy

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.

Positive impact on the 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 several hundred megawatts unit size. What’s more, modifying an existing plant can extend its lifetime significantly.
