shengli boiler scale

Estimate maximum water capacity, and then calculate the initial dosage. Dissolve the drug firstly by infusing the water into a container and then adding the solid BF-30a in a certain amount, which can make into the solution with the weight ratio less than 10%. After stirring the solution, pour the solution into the softening tank and get into the boiler system through the feed pump. Because the low temperature of the water in the water boiler, the water in general is not in the saturated state and is in evaporation and concentration without water. The feed water amount for the system is not large, only about 5% of the system water amount. So the initial dosing for the water boiler system before operation plays an important role for the anticorrosion and descaling. So the initial dosage should be more than the dosage for the operation. After the initial dosing, keep the system water pH more than 10.5. Dosing for the operation During the operation of the boiler, dose the drugs according to the dosage calculated by the formula that the feed water amount for the water tank every time or every day* dosage for the operation feeding water. url:http://www.slboilers.com
