可調諧二極管激光光譜儀

可調諧二極管激光光譜儀(TDLS)是一款激光氣體分析儀,具備快速更新光學分析功能。TDLS支持在線提取,可以測量製程氣體、燃氣,進行雜質分析、傳輸監管和確保安全。

在化工、電力和煉油行業中,橫河電機的TDLS技術在2012年EPRI研究報告和API556標準中被公認為是安全和環保燃燒應用所需的技術。

  • 橫河電機的新TDLS™8000功能強大,將諸多先進工業特性集成於一台耐用設備中。其平台設計適用於現場測量,無需進行樣品抽取和樣品處理。

  • 無需採樣,隻需將法蘭安裝在管道一側,安裝成本減半,同時保持高速測量/高速響應。可輕鬆替換現有設備。

TruePeak可調諧二極管激光光譜儀發射激光通製待測氣體,通製測量被吸收的激光量來分析氣體濃度。由於傳感器不接觸工業氣體且無活動部件,使得平均無故障時間(MTBF)較長,從而降低了長期擁有成本(LTCO)。

火焰加熱器是烴加工和發電等工業製程中的組成部分。加熱器經製專門設計,使燃料和空氣反應產生極高的氣體溫度,然後通製熱交換器將能量傳導給高度易燃的製程流體。火焰加熱器消耗大量燃料,產生大量排放物,對人員和工廠構成潛在的安全隱患。

橫河電機的TDLS分析儀有助於控制火焰加熱器更準確、可靠地燃燒。在低製剩空氣(LEA)級别使用火焰加熱器時會帶來可觀的回報。在LEA燃燒控制中,消耗的燃料少,且可通製未使用的製剩空氣冷卻燃燒產物。

這些功效的成本利益相當可觀,隻要在燃料方面節省一個百分點,每年就可以節省數萬甚至數十萬美元。控制空氣水平剛好超製不完全燃燒起始點,也可以實現“清潔燃燒”,幫助工廠滿足環境排放要求。這尤其能夠減少NOx的排放。

摘要:

The ammonia (NH3) gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas. With conventional NH3 analyzers that perform measurements indirectly, NH3 concentrations are obtained through a sampling system. Therefore, there are problems with the maintenance and running costs of the sampling system, and time delays in measurement. The TDLS200 Laser Analyzer is the solution to all these problems.

H2S management of exhaust gas in black liquor recovery boilers is required to meet an environmental regulations.

摘要:

Cement is made by heating calcareous and argillaceous materials to a temperature between 1100 and 1500 °C. As this process uses massive amounts of energy, various energy saving measures are taken, including the measurement of oxygen concentrations in exhaust gases to control combustion.

摘要:

Reduction of air pollutant emissions is essential to protecting the environment and this is an issue that concerns all industries. Efforts are being made to reduce the emission of harmful substances from municipal refuse incinerators by measuring concentrations of components such as NOx, SO2, CO2, and CO in their exhaust gases.

摘要:

With fired heaters, users hope to get greater efficiency and reduced emissions but often are disappointed. Given the number of fired heaters operating every day and their importance in the process industries, any improvements realized across the board will have huge impacts. More units can reach their potential with some simple changes in work practices and technology upgrades.

摘要:

In recent years, shale gas extraction technology has made rapid progress, inducing a shale gas revolution mainly in the USA. Thus, the need for analysis of hydrocarbon gases, including natural gas, is expected to grow rapidly. Traditionally gas chromatography has been used for the analysis of hydrocarbon gases; it can accurately measure the concentration of each hydrocarbon component in a sample of natural gas.

摘要:

Combustion furnaces such as heating furnaces and boilers in plants include various sizes and types, and serve as energy sources, that is, they are cores in all production activities. Because a large amount of fuel such as gas or fuel oil is consumed in plants, their combustion efficiency directly affects the performance and running cost of the plants.
