This bio-fueled district heating plant on Knivsta V\u00e4rmeverk<\/a> is producing 60 GWh per year for households located near the plant. The tube bundles in the economizer and the evaporator had to be steam soot blown at least once a day to prevent soot accumulation and to ensure boiler operation.<\/p>\n

The existing erosion and corrosion had ultimately led to leakage in the economizer and unplanned maintenance outages were required frequently. During the last year of operation prior to the economizer replacement in 2011, and after a steady decrease of the boiler output over the years, the output was between 10 and 12 MW.<\/p>\n

To compensate for the power loss, another boiler, which uses a more expensive fuel (log chips) had to be operated, as well as an oil-fired boiler occasionally. The economizer needed to be replaced three times during the period between 1997 and 2011 due to worn out tubes.<\/p>\n<\/div>
