Snížení emisí NOx na granulačním kotli o výkonu 135 t/h pomocí SNCR a posouzení vlivu technologie na účinnost kotle

Abstract

Diploma thesis deals with problems of decreasing of NOx emission by means of SNCR method and the influence technology on the efficiency of the boiler is evaluated. On the basis valid legislation are users obligatory operating firing equipment with limits NOx emissions below 200 mg. mN-3 since 2016. In the introduction are compared availability possibilities decreasing of NOx emissions and acceptable additive is specified. The holes for injections nozzles are designed by means of completion temperature measuring. Individual elements of technology and their function are described. On the basis of completion measurement on boiler is specified boiler efficiency with and without technology SNCR compare and summary of technology benefit.
