What is the typical overall length range for a Cornish boiler _________________?
Show answer Hide answer
Answer: C. 5-7.5 m
Explanation
The Cornish boiler is a traditional horizontal cylindrical shell boiler featuring a single internal fire flue. Historical engineering designs standardized the overall length of Cornish boilers to optimize steam generation. Standard manufacturing dimensions place the overall length of these single-flue boilers between five and seven point five meters. Cornish boilers were widely used during the industrial revolution for stationary steam power applications. The single internal flue houses the grate and combustion zone, surrounded by water in the main shell. These boilers typically operated at relatively low pressures compared to modern water-tube designs.
Industrial historians study Cornish boiler designs as precursors to modern high-capacity steam generators. Space requirements in early factories dictated the compact horizontal layout of shell boilers. Proper sizing of boiler length ensured adequate heating surface area for efficient fuel combustion. Option A specifies lengths between two and four meters, which is too short for a standard Cornish boiler shell. Option B lists a length range that falls slightly short of standard industrial Cornish boiler dimensions. Option D describes boilers that are longer than standard single-flue Cornish manufacturing specifications.
