\"\"<\/a>It started with a desire to reduce the cost of running and maintaining Vattenfall\u2019s own fleet of biomass fired power stations. Today the product \u2013 ChlorOut \u2013 is being installed in plants across Europe.<\/p>\n

The ChlorOut concept \u2013 an innovative approach<\/strong><\/p>\n

Developed over many years by a team of researchers and engineers at Vattenfall, ChlorOut is a technical solution that reduces corrosion and deposit problems in biomass and waste fired power plants. The concept is based on dosing of sulphate based additives to the flue gas in order to convert corrosive alkali chlorides to less harmful sulphates, and a unique measurement device called IACM (in-situ alkali chloride monitor).<\/p>\n

\u201cIt was known that sulphur-rich fuels cause less corrosion, but we pioneered the dosing of sulphates in the upper part of the furnace<\/em>,\u201d says Jonas Alin, Business Development Manager at ChlorOut AB<\/a>, <\/strong>a wholly-owned subsidiary of Vattenfall established in February 2011 to market the technology outside the Vattenfall Group.<\/p>\n

A further advantage of implementing the ChlorOut concept is that emissions of nitrogen oxides and dioxins can be reduced.<\/p>\n

\u201cOur main focus has been to mitigate corrosion and the formation of deposits, but the reduction of emissions is an additional benefit which makes the ChlorOut concept stand out from competing, similar techniques<\/em>,\u201d, Alin says.<\/p>\n

IACM <\/strong>\u00ae<\/sup> \u2013 a powerful tool<\/strong><\/p>\n

The IACM instrument measures the concentration of gaseous alkali chlorides on-line. The measuring principle is based on molecular absorption over a certain wavelength interval. IACM enables control of the required amount of the ChlorOut additive as well as on-line quality control of the incoming fuel mix by measuring the concentration of KCl.<\/p>\n

ChlorOut<\/strong> AB<\/strong> \u2013 significant growth potential<\/strong><\/p>\n

ChlorOut AB holds the patents and exclusive licensing rights to the ChlorOut technology. As part of the growth strategy, ChlorOut AB is aiming to establish business relations with boiler manufacturers, technology suppliers and engineering companies looking to boost their offering with an\u00a0 innovative and cost effective way to reduce material and maintenance costs for biomass and waste fired boilers.<\/p>\n
