Zvishandiso izvi zvinobatsira vashandi kuti vatore ammonia nemazvo sechinhu chinodzikisa mukurapa flue gas, kuona kusawirirana kana kusvibiswa, uye kuchengetedza kugadzikana kwemaitiro. Semuenzaniso, inline density metres inodzivirira kubva pakuwanda kweammonia kusina kunaka, nepo tembiricha sensors ichinyevera nezvekupisa kusingawanzoitiki kunogona kuratidza kubuda kwemvura kana kuita. Kuburikidza nekubatana kwemidziyo yakadaro chete ndipo panogona kuwanikwa kuchengetedzeka kwakanyanya, kuderedza nitrogen oxides (NOx) inoshanda zvakanaka, uye kutevedzera tangi rekuchengetedza nguva dzose.
Kutarisa nguva chaiyo kunobatsira sei kuchengetedza mitemo inotevedzera mitemo yekuburitsa gasi rinobuda mumhepo?
Kutarisa panguva chaiyo kunoita kuti pave nekudzora mashandiro ega kwegasi rinobuda mumhepo. Nekutevera kumanikidzwa, kuwanda, kuyerera, uye huwandu hwematangi, vashandisi vanogona kugadzirisa kuyerwa kweammonia kuti vaone nzira dzinoshanda dzekuderedza nitrogen oxides (NOx). Izvi zvinoshandawo sedziviriro yekudzivirira kuburitswa kwemvura netsaona panguva yekushanda, zvichitsigira magwaro ari kudiwa nemasangano anotonga. Mhinduro dzakakwana dzekutarisa dzinobatsira makambani esimbi nesimbi kusangana nezvinangwa zvekubudisa mweya, kunyanya sezvo kutevedzera kuburitswa kwemhepo kuchiongororwa pasi pemirairo yakasimba yekudzora kuburitswa kwemhepo mumhepo.
