Question 1 of 27070

Boiler water samples should be circulated through a cooling coil prior to analysis because __________.

🔍 Key Concepts

• Boiler water sampling procedures and why temperature control matters • Relationship between temperature, flashing to steam, and safe sampling • What properties like conductivity, suspended solids, and pH actually depend on temperature

💭 Think About

• Think about what happens when very hot, pressurized boiler water is suddenly exposed to lower pressure conditions during sampling. • Ask yourself which test result (flashing, suspended solids, conductivity, pH) would be most directly affected if the sample is not cooled before analysis. • Consider which answer choice describes a basic safety/accuracy reason common to most boiler water test procedures, rather than a very specialized effect.

✅ Before You Answer

• Verify how boiler pressure and temperature relate to the water’s tendency to flash into steam when pressure is reduced. • Consider whether conductivity and pH measurements are described correctly in relation to cooler temperatures. • Check if reducing suspended matter in dead-end lines is actually the primary reason for using a cooling coil, or just a possible side issue.

Question 1 of 27070

Boiler water samples should be circulated through a cooling coil prior to analysis because __________.

this prevents the boiler water from flashing into steam as the sample is collected

it reduces the amount of suspended matter that frequently finds its way into the dead end lines

the cool sample has a higher conductivity measurement and the total dissolved solids in the water are easier to identify

the degree of acidity as measured on the pH recorder is amplified by cool water temperatures
