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 controls required.

Design considerations. The main goal when designing a boiler is to extract as much of the energy from the fuel as possible. To do so, both the fixed carbon and volatile matter must be burned completely. Since one part is solid and the other gas, this task is not easy. The boiler must be at very high temperatures, anywhere near 500 o C, and must burn the fuel continuously at a constant rate.
