Boilers

Most boiler manufacturers design and build machines that operate with water, steam or oil.

Tubeless
Boilers that are vertical most of the time with a center drum that is surrounded with transfer lines for the transporation of fuel.
Fire Tube

On this type of boiler, the combustion products move inside the tubes while water is outside the tubes and the drum. Boilers with two, three and even four passes exist. A pass is the number of times the combustion products run trough the boiler.
Water tube

The operating principle of this type of boiler is opposite to that of the fire tube boiler. Water moves inside the tubes while the combustion products move outside them and the drum. 
Coiled pipes

In these boilers, water moves in coils heated by a center heater. The steam chamber is located in a tank over the machine.
