Using a starting point of 5 gallons Boiler Acid # B.L. 70 to each 100 gallons of water and estimate the need of adding 2 gallons every ½ hour per 100 gallons of water for a period of 8 hours would make approximately the total acid needed to acidize a boiler approximately 21 to 29 gallons acid per 100 gallons water depending on an 8 hour or 12 hour acidizing job.Get A Quote
In addition, after an acid wash, the problem of hard wa ter should be rectified, to prevent the same cleaning procedure from happening again. With the scale deposit removed from the boiler you will see an increase in boiler efficiency. Deposits of Calcium Scale of 1/32" will reduce boiler efficiency by 8% 1/8" will reduce boiler efficiency by 25%Get A Quote
