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 changes in steam demand, rather than automatically adjusting the air or fuel supply. This allows the burners to efficiently meet a wide variation in steaming loads without wasting fuel or overproducing steam. The other options are incorrect because they do not accurately describe how these types of burners are designed to operate.
