二極管激光氣體分析儀LDS的基本設(shè)計(jì)使得過(guò)程氣體分析和連續(xù)排放監(jiān)控中機(jī)會(huì)獲得提升。原處安裝式的優(yōu)勢(shì)的主要部分是測(cè)量是非侵入地和實(shí)時(shí)地實(shí)施的,沒(méi)有氣體采樣或氣體調(diào)節(jié)的任何擾動(dòng)或延遲。

總體優(yōu)勢(shì)是由單獨(dú)的過(guò)程決定的。大多數(shù)情況下,簡(jiǎn)練的方法會(huì)導(dǎo)致一個(gè)更高的效率以及安裝和維護(hù)的低工作量。因此,快速原處測(cè)量可以使得多數(shù)過(guò)程的利潤(rùn)率和環(huán)境兼容性獲得提升。

除了排放監(jiān)控以外,在很多工業(yè)應(yīng)用中二極管激光分析儀被證實(shí)是過(guò)程優(yōu)化的一個(gè)標(biāo)準(zhǔn)工具。在過(guò)程行業(yè)的重要的市場(chǎng)細(xì)分中,你將會(huì)發(fā)現(xiàn):

■ 電力/ 燃燒行業(yè)

通過(guò)在SCR和SNCR安裝后面的氨水的測(cè)量來(lái)監(jiān)視和優(yōu)化DeNOx裝置

■ 廢熱處理

通過(guò)加熱爐和鍋爐中的氧氣濃度和氣體溫度的快速測(cè)量的主燃燒控制

在廢氣清理步驟之前和之后,通過(guò)測(cè)量廢氣濃度監(jiān)視和優(yōu)化清理系統(tǒng)

■內(nèi)燃機(jī)

引擎測(cè)試機(jī)床上的廢氣系統(tǒng)中的DeNOx催化劑之后的氨水的測(cè)量

■ 爆炸安全

諸如CO和CH4的氣體的直接和固有存儲(chǔ)濃度測(cè)量或過(guò)程流體、罐、簡(jiǎn)倉(cāng)中的氧氣級(jí)別監(jiān)視

■ 腐蝕保護(hù)

腐蝕氣體混合物中水分的快速和非侵入監(jiān)視
