Abstract
Vaermeforsk has carried out two R and D projects with the objective to investigate the possibilities in reducing NO{sub x}-emission in moving grate fired boilers by primary measures. The tests were performed 1989 and 1990 in a 12 MW generator-boiler at Mjoelby-Svartaadalens Energiverk AB (MSEAB). The recommended modifications and investments were carried out 1991. Due to a general interest to know the practical results of the R and D, this report comprises an evaluation of achievements made. In the report the following subjects are evaluated: * Phases of buying, take over, optimisation and education of staff. * NO{sub x}-reducing system layout and control strategies. * Practical effects of R and D-recommendations made, i.e. how large was the NO{sub x}-reduction. * Difference between R and D and practical reality. * Economy. * Running problems, need of maintenance and necessary modifications. In short the results are: * The recommended R and D-measures was valid. * The primary measures, including stack gas recirculation, has exceeded the expectations of the R and D. The expected reduction was close to 35% and is today about 50%. * No important negative effects from the stack gas recirculation system have been identified. The operating costs, except for
