Question 328Steam Plants - Assistant Engineer70% to pass
Boilers equipped with steam atomizers can operate over a wide load range without cutting burners in and out because _______________.
AI Explanation
The correct answer is B) steam velocity aids in the atomizing of fuel oil over a wide range of fuel pressures.
In boilers equipped with steam atomizers, the steam velocity helps to effectively atomize the fuel oil over a wide range of fuel pressures. This allows the boiler to operate across a wide load range without the need to constantly cut burners in and out. The steam velocity maintains the proper atomization of the fuel, ensuring efficient combustion, regardless of changes in the fuel pressure. The other options are incorrect because they do not accurately describe the key mechanism that enables boilers with steam atomizers to operate efficiently over a wide load range.
