UPM Shotton Boiler 7: Difference between revisions

A Biomass Waste [[Combined Heat and Power]](CHP) EFW based at the [[UPM Shotton[[ newsprint mill in Flintshire, north Wales generating 24.8 MWe<ref name="UPM">[https://www.upm.com/news-and-stories/articles/2016/02/increasing-renewable-energy-production-at-shotton/ UPM]</ref> from a [[Biomass]] feedstock of waste paper, fibre, sludge and [[Wood Waste]]<ref name="CHP">[https://books.google.co.uk/books?id=CHtwAgAAQBAJ&pg=PA437&lpg=PA437&dq=Power+technology%2BShotton+paper+mill%2BCHP&source=bl&ots=VxBt9DTQPM&sig=ACfU3U35q44SMYAznVy9CIrOu-kPAevvxA&hl=en&sa=X&ved=2ahUKEwj7iNuim-boAhXUSBUIHSAHArMQ6AEwB3oECAsQKQ#v=onepage&q=Power%20technology%2BShotton%20paper%20mill%2BCHP&f=false /Small & Micro CHP Systems]</ref>. The plant provides up to 70% of the paper mill's energy production<ref name="UPM" />. Most of the energy is consumed in the manufacture of mechanical pulp, pumping and paper drying<ref>[https://cld.bz/bookdata/helJYL/basic-html/page-66-67.html#/ UPM Annual Report 2016]</ref>. In 2016 a second steam turbine was brought on line at the facility which utilises excess steam from the biomass CHP plant<ref>[https://www.twosides.info/UK/solar-success-for-upm-shotton/ Two sides]</ref>.

The technology in use at the plant is a Bubbling Fluidised bed system<ref name="CHP" />. The biomass facility cost an estimated £59m<ref>[http://www.downton.co.uk/case-study/upm/ Downtown]</ref>.

==Tonnage Input/Fuel==

The tonnage received by the plant is a mixture of [[Biomass]] and in the most recent [[Annual Sustainability Report]] for 2018-19<ref>[https://www.ofgem.gov.uk/publications-and-updates/biomass-sustainability-dataset-2018-19 Biomass Sustainability Dataset 2018-19]</ref> [[Ofgem]] reported the following fuel received ([[Wood Waste]] representing 46% of input):

The [[Wood Waste]] tonnage received cannot be directly compared with the stated historical tonnage received and recorded in the [[NRW]] statistics as these are recorded on a calendar year basis (i.e. January 2018 to December 2018) and were not available.
