Next project contracted


Two 400 MW FBC boilers of the client to be changed from coal and biomass to several sorts of non-tyre rubber waste. Basic theoretical and experimental investigations were carried out.

Main issues answered to the client:

What are the worldwide experiences on the combustion of rubber? Are there problems in case of specific sorts?

Can the received rubber samplesbe be fluidized with common bed materials?

Which gaseous components will be released by this high-volatile fuel before and after entering the combustion chamber?

In case of which types of this fuel are special problems expected? Can these problems be handled? How?

Which bed materials and particle sizes are appropriate for the fluidized bed combustion of the non-tyre rubber samples in question?

What changes should be carried out on the existing boilers of the client for accepting non-tyre rubber?

Are bed agglomeration and deposition problems expected? If yes, where and in case of which sorts of non-tyre rubber?

Is co-combustion with low-grade, high sulfur local coals a promising solution?
