Select the correct comparative statement regarding Cornish and Lancashire boilers _______________?
Show answer Hide answer
Answer: D. lancashire has two fire tubes and cornish has one
Explanation
A Lancashire boiler incorporates two internal fire tubes, whereas a traditional Cornish boiler contains only one. This dual-flue design in Lancashire boilers increases the internal heating surface area for enhanced steam production. Boiler classification standards distinguish these shell boiler types primarily by their internal fire tube counts. Shell boilers feature cylindrical vessels where hot combustion gases pass through internal tubes surrounded by water. Cornish boilers were developed earlier with a single large horizontal internal flue passing through the water space. Lancashire boilers improved upon Cornish designs by adding dual parallel flues and better draft control systems.
Historical industrial steam plants relied heavily on Lancashire boilers for reliable stationary power generation. Comparing boiler types helps engineers select appropriate steam generation equipment for industrial manufacturing needs. Proper internal flue configuration ensures efficient heat transfer from combustion gases to the surrounding boiler water. Cornish and Lancashire boilers are classic fire tube boilers rather than water tube boiler designs. Stating that Cornish has two tubes and Lancashire has one reverses the actual engineering specifications. Claiming both have two fire tubes ignores the single-tube construction characteristic of traditional Cornish boilers.
