20 tons of gas boiler minimum load

2. BOILERS - Bureau of Energy Efficiency

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.

How to Calculate Gas Consumption in a Gas Boiler Burner?

Boiler turndown is the ratio between a boiler's maximum and minimum output. Depending on the burner's design, it may have a turndown ratio between 4:1 and 10:1 or even higher. A 4:1 turndown means the boiler's minimum operating load is 25% of the boiler's full capacity ( capacity divided by 4).
