Some sample context:

Package Boilers are commonly called Water or Fire Tube Boilers. Water Tube Boilers utilize convection heating, which draws the heat from the fire source, and passes against the generating tubes of the boiler, causing water inside those tubes to boil off into steam. Fire Tube Boiler arrangement utilizes conduction heating which transfers heat from physical contact. Fire Tube Boilers are not commonly used due to their method of conduction heating because pipes in direct contact with fire and cold water could damage the pipes. The package boiler is usually a two or **three-pass fire-tube boiler** with an internal furnace tube. This is similar to the much earlier Scotch boiler.
