New York Low Pressure Boiler COF Practice

In the given formula, what does TS represent?

1. Temperature of steam

2. Tensile strength of shell plates

3. Total surface area

4. Thickness of the shell

The correct answer is: Tensile strength of shell plates

In the context of boiler design and operation, when referencing formulas that involve the physical characteristics of a boiler, TS typically stands for "Tensile Strength." This refers to the maximum amount of tensile (pulling or stretching) stress that a material can withstand before failure occurs. Understanding tensile strength is crucial in boiler design because the materials used for construction must be able to withstand the high pressure and temperature conditions inside the boiler. Adequate tensile strength ensures that the shell or pressure vessel remains safe and operational under these stresses, preventing catastrophic failures such as ruptures. In contrast, options like temperature of steam, total surface area, and thickness of the shell are all important concepts in boiler operation and efficiency but do not align with the meaning of TS in this particular context.
