1.	Which type of boiler is it when the furnace is placed in the region of boiling water?(a) Internally fired boiler(b) Externally fired boiler(c) Babcock-Wilcox boiler(d) Stirling boilerThe question was asked during an interview.The question is from Boiler Classification topic in chapter Steam Generators & Accessories of Energy Engineering
Answer» Correct choice is (a) INTERNALLY fired boiler For explanation I would say: If the furnace REGION is PLACED in the region of boiling WATER, the boilers are termed as internally fired boilers. EX: Lancashire boiler. If the furnace is placed outside the boiling water region, the boilers are known as externally fired boilers. Ex: Babcock-Wilcox boiler.
