70% to passOil accumulation in boiler water would _______________.
Acause foaming and carryover from the boiler
Bprevent acid attack on the boiler tubes
Cpractically eliminate boiler sludge formation
Dincrease the heat transfer rate
AI Explanation
The correct answer is A) cause foaming and carryover from the boiler. Oil accumulation in boiler water can lead to foaming and carryover, which means the water and steam escaping the boiler will contain water droplets and impurities. This can be detrimental to the boiler operation and downstream equipment. Oil in the boiler water does not prevent acid attack on the boiler tubes (B), nor does it eliminate sludge formation (C). It also does not increase the heat transfer rate (D), and in fact, oil accumulation can reduce heat transfer efficiency.
