Carbon content in fly ash microwave
WebNov 1, 2024 · This paper presents a high-precision measurement based on microwave to detect unburnt carbon (UC) content. The key idea of the approach is to use two parameters (S 21 amplitude and phase) to establish a concentration-independent expression to eliminate the influence of the fly ash (FA) concentration. Compared with single … WebAn apparatus for measuring carbon content in fly ash is described comprising, an absorption chamber having an inlet conduit and an outlet conduit. The inlet conduit has a …
