In Sweden, the average black liquor recovery boiler is rated at 1800 TDS\/day. The typical steam consumption of the sootblowers is 5-10 % of the produced steam. In the average sized boiler, sootblower steam consumption is around 16 tons\/hour, which can be used for 2-2.75 MW electricity, depending on steam data and type of turbine. With a yearly operation time of around 8,500 hours, this adds up to 545 GWh of electricity for 27 black liquor boilers. Roughly 45% of this can be saved by using a more efficient steam soot blowing system. H\u00f6g effektig sotbl\u00e5sningssystem (HISS)<\/a>, is our patented method of optimizing steam sootblowers, i.e., saving 245 GWh of electricity. This corresponds to the yearly production of 40, 150m high wind turbine towers.<\/span><\/p>\n

Now, let\u2019s apply this globally. There are more than 450 recovery boilers around the world so, if we assume the same average boiler size and sootblower steam consumption as in Sweden, we end up with a potential total savings of around 4080 GWh of electricity per year. This corresponds to the yearly production of 660 wind turbine towers.<\/span><\/p>\n

Today, one third of the black liquor boilers in Sweden are equipped with HISS<\/a>, and we are sure that more and more will follow\u2014 not just in Sweden, but around the world. Increasing the electrical output, as mentioned above, is one alternative for boosting mill revenue using sustainable, de-carbonizing power generation. But some plants use HISS<\/a> instead to step up the number of sootblower starts <\/span>or combine increased starts with steam savings\u2014and, thereby, increase boiler availability and mill production. <\/span><\/p>\n

Den HISS system<\/a> offers unique flexibility when it comes to operating recovery boilers in the most sustainable and economical way.<\/span><\/p>\n<\/div>
