Carbon Monoxide Poisoning: Checking for Complete Combustion …

Shell boilers, also known as flue boilers, have a long water tank configuration with fire tubes. The heat from the furnace or combustion chamber passes through these fire tubes to heat the water. The earliest form of this type of boiler was the Cornish boiler, which consisted of a long cylinder with a single large flue or pipe that contained the heat or fire.
