QUESTIONS WITH VERIFIED ANSWERS.
What are two types of heat exchangers commonly used in steam boilers? - (ANSWER)1. Shell and tube
heat exchangers. 2. Plate heat exchangers.
What is the function of the steam drum in a steam boiler? - (ANSWER)The steam drum collects and
stores steam generated by the boiler and regulates pressure within the boiler system.
What does an economizer do in a boiler system? - (ANSWER)An economizer preheats the feed water
before it enters the boiler, utilizing waste heat from flue gases to improve fuel efficiency.
What is the role of a superheater in a steam boiler? - (ANSWER)The superheater increases the
temperature of the steam generated by the boiler, enhancing thermal efficiency.
What do regulators in steam boilers control? - (ANSWER)Regulators maintain key parameters such as
pressure and temperature within the desired range for safe and efficient boiler operation.
