Sweden Test Report on 1 MW Pyro Plasma Torch
Long report but good news for Pyro.
Why people think SAT will not work.?
We had FAT in Montreal in front of Vale Engineer/Staff
Conclusion from the report in Sweden as follows:
Implementation of plasma torches may be an alternative for electrification of the straightgrate process and can decrease the CO2 emissions from the process significantly. Retrofitting plasma torches in place of fossil fuel burners in a pelletizing plant with a 40 MW thermal input has the potential to reduce CO2 emissions by up to 140 000 ton per year. It has been concluded that the implementation of plasma torches in the straight-grate process only has a small effect on process parameters and energy consumption. With plasma torches, there will not be any combustion reaction and thus no combustion products in the process gas. This leads to slightly higher oxygen content in the gas which results in a higher oxidation rate of the pellets. There will also be an introduction of an external plasma forming gas which increases the process gas flow and changes its composition. However, this will only affect the process conditions significantly at very high flow rates. With increased oxidation, the process can be optimized, for example towards decreased energy consumption or increased production rate
