Abstract (en)
During operation of a fossil fuel boiler the combustion process results in the deposition in the boiler flues and heat transfer pipes of scale, smut and soot and other solid products which have a serious effect on boiler efficiency. Regular cleaning therefore has to be undertaken in order to maintain a reasonable standard of boiler efficiency and this is both expensive and time consuming. The present invention introduces controlled amounts of ferric oxide (Fe2 O3) the effect of which is to inhibit the deposition of further solid combustion products such as scale, soot and smut and also to alter the character of existing scale, reducing its adhesion and causing the scale to fall away. The effect is to improve boiler efficiency and reduce maintenance costs.
