Question 458Steam Plants - Assistant Engineer
70% to passStrainers are installed in boiler fuel oil service lines to _______________.
Aadsorb water
Bremove solids
Cabsorb contaminants
Ddecrease viscosity
AI Explanation
The correct answer is B) remove solids. Strainers are installed in boiler fuel oil service lines to remove solid contaminants, such as rust, scale, or other particulates, from the fuel before it enters the boiler. This helps prevent damage to fuel system components and ensures consistent fuel delivery to the burner. The other answer choices are incorrect because: A) adsorbing water is not the primary function of a strainer, C) absorbing contaminants is not the role of a strainer (that is the function of a filter), and D) decreasing viscosity is not the purpose of a strainer in the fuel oil system.
