Boiler load - The horsepower, lbs of steam per hour, or BTU is the rating indicating the maximum capacity of a boiler. When a boiler operates at its maximum rated capacity, it is referred to as maximum load. If the load varies from hour to hour, it operates at a varying load.Load and load variations can influence the amount of chemicals required for treatment and the treatment …

From Example 8.2, the existing boiler has an excess O 2 of 6% and an overall boiler thermal efficiency of about 78% (i.e., η s t d = 0.78). After the boiler tune-up, the excess O 2 is 3%. Using the monograph of Fig. 8.12, the new boiler efficiency can be determined from the flue gas temperature (343°C or 650°F) and the excess O 2 (3%).
