Question 61General Subjects - QMED
70% to passConstant capacity, pressure atomizing, fuel burners designed to meet a wide variation in steaming loads on an auxiliary boiler, are _______________.
Aautomatically supplied with warmer air on demand
Bautomatically supplied with more fuel on demand
Cequipped with standard variable capacity atomizers
Dcycled on and off in response to steam demand
AI Explanation
The correct answer is D) cycled on and off in response to steam demand. Constant capacity, pressure atomizing, fuel burners on auxiliary boilers are designed to cycle on and off in response to the varying steam demand, rather than automatically adjusting the air or fuel supply. This allows the burners to maintain a consistent atomization and combustion efficiency across a wide range of load conditions, without the need for complex variable capacity systems. The other answer choices, such as automatically adjusting the air or fuel supply, are not the typical design approach for these types of burners.
