氧化鋯式氧氣濃度計 ZR22G、ZR802G

有助於降低 OPEX

有助於降低營運支出(OPEX),並可在無需取樣裝定的情況下,於高溫環境中連續量測氧氣濃度與濕度。

本分析儀基本構成為一支探頭與一個轉換器,可同時作為氧化鋯式氧氣濃度計與高溫濕度分析儀使用。

ZR802G 轉換器採用數位顯示設計,除顯示氧氣濃度外,亦可顯示感測元件溫度與元件電動勢(EMF),並內建人機介面(HMI),提供直覺化的觸控操作。此分析儀適用於大型或小型鍋爐、各類工業爐與燃燒設備的燃燒氣體氧氣濃度監測,亦適合用於低氧燃燒控制應用。

 

分離型 氧化鋯式氧計濃度計分析儀,可用於連續量測以電熱器或高溫氣體作為熱源之乾燥設備中的高溫氣體濕度。亦可應用於加濕設備及各類製造製程中的乾燥設備,用於濕度量測與控制,有助於提升相關應用領域的生產效率。

摘要:

To detect air leaks, an oxygen analyzer is used. The ZR22/ZR802 Direct In-Situ Zirconia Oxygen Analyzer has been well received due to its good response speed, stability, and maintainability.

摘要:

Drying is an important part of the papermaking process that evaporates the remaining water in the wet paper web. This is performed with a dryer, and the humidity control in this dryer is essential to maintaining high paper quality (e.g., strength, paper surface) and high heat energy efficiency.

摘要:

There are various methods for continuous fabric dyeing as well as dye fixing. When dye is directly applied, steaming (heat treatment) is required. At present the pad-steam method is widely used for continuous dyeing. To ensure stable product quality, the humidity in the steamer is kept at a constant level.

摘要:

Humidity control is important to maintain product quality and improve yield. The ZR402G/HS Direct In Situ Zirconia High Temperature Humidity Analyzer is easy to maintain as it requires no sampling system.

摘要:

A furnace for heating slabs needs to be operated under low oxygen conditions at high temperatures of 1000°C and above to prevent oxidation of the steel. The measurement of oxygen concentrations in the furnace is essential in this process. (AN 10M01F01-03E)

摘要:

In a pulverized coal-fired boiler of a large power plant, an oxygen analyzer is essential for combustion control. A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust).

摘要:

In a hot blast stove, the by-product gas produced in a coke oven is burned to preheat the air blast for the blast furnace. To improve the combustion efficiency and conserve energy in a hot blast stove, it is essential to be able to control combustion by measuring and adjusting the oxygen concentration in the exhaust gases.

摘要:

A package boiler operates more efficiently if the oxygen concentration in the flue gas is reduced. Optimizing air intake for boiler operation requires continuous measurement of the oxygen concentration in the flue gas.
