Abstract

The aim of this study was to find out in practice the effects and costs of NO{sub x} -reduction in oil-fired boilers by using the selective non-catalytic reduction (SNCR) technology The tests were made in a 40 MW{sub t}h oil-fired DH-boiler owned by town of Joensuu. The equipment and automation for the injection of ammonia/urea was delivered by Pentol GmBH, Germany. The reactive substance was ammonia-water liquid, which was injected into the furnace at a temperature of about 1 000 deg C, where there should be no undesired reactions after the furnace caused by the reaction between ammonia and sulphur trioxide. The results of this reaction are ammoniumsulphates, which can be very corrosive. The dependence of the reaction from the furnace temperature and the reduction rates with NH{sub 3} /NO mole ratios between 1.0 - 2.5 were studied
