Directions for use

NALFLEET™ Autotreat is a boiler water conditioner designed for optimum protection of ships boiler systems when used in conjunction with an oxygen scavenger. The product combines well known phosphate treatment with new polymer technology. This ensures that precipitates are kept soft and nonadherent for easy removal by blowdown. The product should always be used in conjunction with an oxygen scavenger, preferably NALFLEET™ Oxygen Scavenger Plus. Note that this product is formulated for use in conjunction with good quality feed water.

Dosing method

The product should preferably be dosed continuously with an automatic dosing unit. Alternatively the product can be fed into the feed line by means of a by-pass pot feeder.

Dosage and control

Initial fill dosage is 2.4 litres of NALFLEET™ Autotreat/ton of boiler capacity to reach a P-Alkalinity level of approx. 200 ppm. For an untreated system it is recommended to initially bring the treatment up to a suitable level of 200 ppm p-Alkalinity. The dosage chart given below is for convenience to determine the amount of product required to elevate P-Alkalinity. Note that the table is based on reaching 200 ppm.

These are recommended values based on experience, and are in no way intended to replace the boiler manufacturers specifications, or company regulations. Typical control limits are: * P-Alkalinity: 150-300 ppm as CaCO3. * Chlorides: 200 ppm Cl max. * Condensate pH 8.3-9.0. Excessive Chlorides are removed by blowdown.

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 that treatment levels are correct.

使用说明

NALFLEET™Autotreat是一种锅炉水调节器，设计用于与氧气清除剂配合使用时对船舶锅炉系统的最佳保护。该产品将众所周知的磷酸盐处理与新的聚合物技术相结这确保沉淀物保持柔软和不粘附，以便通过排污容易地除去。该产品应始终与氧气清除剂一起使用，优选NALFLEET™氧气清道夫加。请注意，该产品可与优质给水配合使用。

加药方法

产品应优选连续配有自动加药装置。或者，可以通过旁路桶式进料器将产品进料到锅炉进料管线中。

剂量和控制

初始填充剂量为2.4升NALFLEET™Autotreat /吨水锅炉容量，达到P-碱度水平约。200 ppm。对于未经处理的系统，建议最初使处理达到200ppm p-碱度的合适水平。下面给出的剂量图是为了方便确定提高P-Alkalinity所需的产品量。请注意，该表基于达到200 ppm。

P-碱度                     0                50         100                  150       200       250                   300       350

Dose in l/ton             2.4 1.8                    1.2                    0.6                   0            0          0          Blow Down

P-碱度如ppm CaCO3.

这些是基于经验的推荐值，绝不是要取代锅炉

制造商规格或公司规定。典型的控制限制是：

• P-碱度: 150-300 ppm as CaCO3.

• 氯化物: 200 ppm Cl max.

• 冷凝水pH 8.3-9.0.

通过排污除去过量的氯化物。

采样和测试

排污后始终从同一点取出，立即冷却并测试。按照WSS测试套件说明进行操作，并将结果记录在防水中。结果应按照防水说明中的说明发送至WSS。

重要的是进行定期测试以确保治疗水平正确。
