A good summary here:
In October 2019, Atlantis announced that it had awarded Mitsubishi Hitachi Power Systems Europe GmbH (MHPS) the contract to carry out the design and development of the combustion system for the flagship Uskmouth Conversion Project in Newport, Wales. This contract included the largest ever combustion testing of the waste-derived fuel pellets, which will be used as fuel in the plant, at Mitsubishi Heavy Industries’s Research & Innovation Centre in Nagasaki, Japan.
The test conclusively proves that a pulverised fuel burner based on MHPS’s DS Ultra Low NOx burner can be used to stably combust the waste-derived fuel unsupported – in other words without any oil or gas support firing.
The burner was able to operate continuously at 25 MW thermal power using the fuel and is comparable in rating to the burners required for the Uskmouth Conversion Project.
During the testing, MHPS established that it was possible to feed large volumes of pulverised fuel to the burner via a pneumatic system without disturbances, at a rate that is comparable to that required at the Uskmouth Conversion Project.
MHPS also investigated and confirmed that flue gas emissions were within anticipated levels and that the burner was able to achieve expected low nitrogen oxides (NOx) performance whilst maintaining low carbon monoxide (CO) levels.
Following the successful completion of the test, the final stages of the pre-engineering, procurement, and construction (EPC) detailed design contract are now underway.
Final design studies include using the successful combustion test results to validate the computational fluid dynamics modelling, carrying out a more detailed Uskmouth boiler system refurbishment design, and confirming the requirements for refurbishment and enhancement of the existing flue gas treatment system.
MHPS will have completed all of this work by Q4 2020 at which point they will be able to make an offer for a fixed price supply of the combustion system under an EPC contract with terms and conditions suitable for project finance.
The bespoke fuel pellets, designed and produced by project partner and leading Dutch alternative fuel specialist N+P Group, contain approximately 50 percent biogenic waste material such as paper and cardboard, with the remainder made up predominantly of plastic waste.
