The ultra-supercritical boiler was originally designed to burn natural gas and heavy fuel oil.

The bag filter system removes more than 99% of solid particles from the flue gases coming out of the boiler. About 50 trucks with straw a day are transported to the power plant from farms located in eastern Denmark. Straw ash is returned to the fields as fertilizer.<\/p>\n\n\n\n<p>To keep the wood pellets dry and minimize dust, all operations are performed indoors. The existing coal conveyors are covered and dust is removed from strategic places with a vacuum cleaning system.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"731\" height=\"502\" src=\"https:\/\/uabio.org\/wp-content\/uploads\/2021\/09\/avedore-2.png\" alt=\"\" class=\"wp-image-11226\"\/><\/figure><\/div>\n\n\n\n<p><strong>Power at full load (net)<\/strong><\/p>\n\n\n\n<p>435 MW of electricity without gas turbines \/ 585 MW of electricity with gas turbines.
