Blowdown boiler thoroughly to eliminate loose scale and corrosion. If necessary, clean the system with State ACIDINE®. The proper amount of treatment depends on feedwater hardness, 补给水, 锅炉排污频率和排污容量. It is important to maintain both the correct level of BT-128 and the proper solids level (controlled by the blowdown) for protection against scale. See your 国家工业 产品 Representative for recommendations on treatment amounts for your system.

蒸汽锅炉
Add through the vent or the opening into the condensate receiver, 给水箱, 补给箱或调压箱. Add treatment slowly to obtain uniform mixing. Maintain BT-128 between 70-80 ppm as measured by the 国家工业 boiler water product test.

维持治疗: Add BT-128 to maintain product residual of between 70-80 ppm. This level should be monitored daily with test kit to insure that the boiler is properly protected at all times.
排污:防止结垢, blowdown should be scheduled to maintain 3-5 cycles of concentration in the boiler or as recommended by your 国家工业 Representative. 每天用检测试剂盒监测周期.

热水循环锅炉
Initial Treatment: Add treatment directly to boiler drum or through a vent. 慢慢加入以获得均匀的混合. Maintain BT- 128 between 70-80 ppm as measured by the 国家工业 boiler water product test.

维持治疗
Use BT-128 to maintain product residual of between 70-80 ppm. This should be monitored to insure that the boiler is properly protected at all times. 定期排污装置清除污泥.

CLOSED LOOP CHILLER SYSTEMS: BT-128 will work as an on-line cleaner to slowly remove scale already present in the boiler. Maintain 70-80 ppm additive level to accomplish this on-line cleaning. Addition of product should be done at a point as near to the feed water inlet to the boiler as possible. Manual blowdown of the mud drum should be increased to purge the increased amount of the solids generated through descaling. This on-line cleaning procedure will take 2 to 4 weeks at full boiler load. Caution should be used in the case of severe scaling since on line cleaning of large amounts of scale could clog the system. In cases of large amounts of scale, acid cleaning while the unit is not operating is recommended. BT-128 will work as an on-line cleaner to slowly remove scale already present in the boiler.

NEUTRALIZING RINSE AFTER ACID CLEANINGBefore starting a water treatment program with BT-128, acid cleaning of the boiler with State ACIDINE may be needed. After descaling with ACIDINE, thoroughly flush the system with water to remove all acid. 进一步保护金属表面, add 1 gallon BT-128 for every 75 to 100 gallons of water in the boiler. Fill the unit to 6 inches over the normal operating capacity. Circulate this neutralizing solution through the boiler, and allow to soak at least 1 hour. After discontinuing recirculation and lowering the water level to normal, 将设备启动到至少50 psi的压力. Vent the unit during firing to occasionally release any liberated gases. After heating the unit approximately 1 hour, drain it, and flush with clear, warm water. Then refill the unit with fresh water and add BT-128.
