Whatever the type of fuel being fired, all high pressure boilers are bound to have a tube failure during the course of their working life. Did you know that a single tube failure in a 500 MW boiler requiring four days of repair work can result in a loss of more than $1,000,000 apart from the generation loss?

Boiler Basics A boiler is used to heat water that is circulated through a closed loop piping system for general facility and service water heating. Low-temperature systems generally operate below 200 degrees Fahrenheit. Medium-temperature systems generally operate between 200 and 250 degrees Fahrenheit. Most facility boiler systems are fired using a combustible gas, fuel oil, or electricity

A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

High pressure can lead to the boiler failing and your home losing hot water altogether. Before you pick up the phone, it is important to check a few things first. There is a possibility that the pressure has grown because of a unit it is supplying. For instance, a radiator or towel rail that is drawing from the main water tank may require bleeding.
