Directions for use
NALFLEET™ Alkalinity Control provides alkaline conditions in the boiler water for optimum control of corrosion and scale deposition and should be used as part of a multi-product treatment programme.
Dosing method
For optimum results dose NALFLEET™ Alkalinity Control direct to the boiler with an automatic dosing unit, or via the bypass pot-feeder installed in the boiler feed line.
Dosage and control
A proper level of treatment is maintained by testing for p-Alkalinity. The level is determined by the pressure and type of boiler. Refer to the dosage table below for correct dose rates. The normal method of raising the alkalinity level is by adding the required quantity of NALFLEET™ Alkalinity Control after testing for p-Alkalinity. 225 ml/ton will raise the p-Alkalinity by 100 ppm.
USING THE TABLE: Select the section corresponding to the pressure of the boiler to be treated and read across the table to obtain the level of treatment required.

Proper treatment should normally give a pH between 9.5 and 11. These are recommended values based on experience and are in no way intended to replace the boiler manufacturer's specifications or company regulations.
Sampling and testing
A representative sample of boiler water should be drawn for analysis daily. The sample should always be taken from the same point after blowdown, cooled and tested immediately. Follow the WSS Test Kit instructions and log the results in Waterproof. The results should be sent to WSS as stated in the Waterproof instructions.
It is important that regular testing is carried out to ensure levels of treatment are correct.

Product Number Product name
571307 ALKALINITY CONTROL 25 LTR
認證
挪威國家公共衛生研究所批準在淡水發生器中進行酸洗操作後用作中和劑
使用說明
NALFLEET™ Alkalinity Control 可在鍋爐水中提供堿性條件 ,以最佳控製腐蝕和水垢沉積 ,並應作為多產品處理程序的一部分使用 。
加藥方法
為獲得最佳結果 ,NALFLEET™ Alkalinity Control 應在鍋爐配備自動加液裝置 ,或通過安裝在鍋爐給水管路中的旁路罐式進料器 。
劑量和控製
以ml / ton鍋爐體積計的堿度控製劑量通過測試保持適當的處理水平
對堿度 。水位由鍋爐的壓力和類型決定。有關正確的劑量率 ,請參閱下麵的劑量表 。提高堿度水平的常規方法是在測試p-堿度後添加所需量的NALFLEET™ Alkalinity Control 。225毫升/噸將使p-堿度提高100ppm 。
使用表格 :選擇與待處理鍋爐的壓力相對應的部分 ,並在表格中讀取以獲得所需的處理水平 。

適當的治療通常應該在pH值之間9.5和11.這些是基於經驗的推薦值 ,絕不是為了取代鍋爐製造商的規格或公司規定 。
采樣和測試
應每天抽取一份代表性的鍋爐水樣本進行分析 。排汙後應始終從同一點取樣 ,冷卻並立即進行測試 。按照WSS測試套件說明進行操作 ,並將結果記錄在防水中 。結果應按照防水說明中的說明發送至WSS 。重要的是進行定期測試以確保治療水平正確 。
