Beschreibung
Zusammenfassung:FIELD: heat-power engineering; thermal power stations and other industrial objects dealing with burning fuel. SUBSTANCE: device includes bundle of parallel tubes arranged in gas duct across flue gas flow. Tubes have holes for supply of mixture of ammonia with transportation agent (gas or vapor) into flow. Relative pitch of holes corresponds to the following condition: , where S is pitch of holes; d is diameter of holes; wmix is flow rate of mixture of ammonia with transportation agent at hole outlet; wg is flow rate of flue gases; ρg is density of mixture at hole outlet and ρmix is density of flue gases. EFFECT: enhanced economical efficiency of cleaning. 2 cl, 1 dwgl
