The primary boiler fuels are coal, oil, and gas. Oil and gas involve the simplest controls, since they can be measured easily and flow is regulated by a control valve in the fuel line. On the other hand, since coal is an unmeasured fuel, the control system is open-loop, in which a fuel demand signal positions a coal-feeding device (speed

Identifying and correcting the root cause of tube failures is essential to help lessen the chance of future problems. Symptoms: Intergranular micro-cracking.Loss of ductility or embrittlement of the tube material leading to brittle catastrophic rupture. Causes: Most commonly associated with excessive deposition on ID tube surfaces, coupled with a boiler water low pH excursion.

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the four
