Abstract

A system for wetting combustion gases comprises spraying water into the gases and then the water, which is heated by the gases, is collected and pumped through a coolant system where atmospheric air is used to cool the water in a heat exchanger (4).

Description

508 773 , »¿ vattentemperaturen i ledningen 20. Vattenflodet i ledningen 20 regleras så att vattnets utgående temperatur från det andra kondensorsteget blir den samma som vattentemperaturen i ledningen 16. På detta sätt försämras inte systemets värmeåtervinning. Avfuktningen blir bättre ju kallare det är ute, plymen skulle normalt bli värre ju kallare det är ute. På detta sätt reduceras plymen till ntinimunt och stoñreningen blir bra även under vintem när pannan normalt körs med fullefliekt. 508 773, »¿ the water temperature in the line 20. The water det in the line 20 is regulated so that the water the output temperature from the second condenser stage will be the same as the water temperature in line 16. In this way, the heat recovery of the system is not impaired. The dehumidification gets better the colder it is outside, the plume would normally get worse the colder it is outside. In this way the plume is reduced to ntinimunt and the stem cleaning is good even during the winter when the forehead normally runs with full fl iekt.

508 773 Lt' Patentkrav508 773 Lt 'Patent Claim l. System för varmeåtervinning och avfuktning av rökgaser kännetecknat av att vatten sprutas in i rökgasema och att det av rökgaserna uppvärmda vattnet kyls i en värmeväxlare som överför en del av värmet till en användare av värme och att vattnet eller ett delflöde av vattnet kyls i en andra värmeväxlare med en luftkylare varefter vattnet sprutas i de redan kylda rökgasema för avfuktning av rökgasema.l. Heat recovery and dehumidification system of flue gases characterized in that water is injected into the flue gases and that the water heated by the flue gases is cooled in a heat exchanger which transfers part of the heat to a user of heat and that the water or part fl of the water is cooled in a other heat exchangers with an air cooler after which the water is sprayed into the already cooled flue gases to dehumidify the flue gases. 2. System enligt patentanspråk 1 kännetecknat av att delvattenflödet efier den första värmeväxlaren först lämnar en del av sitt värme till befuktning av förbränningslufi innan det kyls med utelufi.System according to patent claim 1, characterized in that partial water fl is the first heat exchanger to leave some of its heat for humidification of combustion flux fi before it is cooled with outdoor flue fi. 3. System enligt något av patenanspråken 1 - 2 kännetecknat av att luft som blåses i utgående rökgaser först uppvärrns av vattenflödet innan vattnet slutkyls i en luñkylare.System according to one of Claims 1 to 2, characterized in that air blown into the exhaust gases is first aggravated by the water fl before the water is finally cooled in a cooler.
