These Are Some Boiler Classifications That You Should Know

The boiler is made to produce steam by heating water in it by hot gases resulting from burning fuel. The boiler must work as efficiently as possible; meaning that it must be able to produce as much steam as possible with minimum fuel consumption. Therefore the construction of the boiler must be such that the heat of the fuel must be absorbed as much as possible by the boiler water to produce steam. To achieve this, the construction of the Calderas is made from the arrangement of pipes that separate water and hot gases that heat the water.

Judging from the position of the boiler pipe is divided into:

Horizontal, for example, Section B & W.
Vertical, for example, Foster Wheeler.
Inclined, for example, B & W Integral.

Judging from the substances flowing in the pipe, the boiler is divided into three groups, namely:

Fire Pipe boiler (Fire Tube Boiler)

In this boiler, hot gases flow in the pipe, while heated water is outside the pipe. Fire pipe boiler is usually used for steam capacity up to 14,000 kg/hour with a pressure of 18 kg / cm2. Fire pipe boiler can use oil, gas, and solid fuel in its operation. For economical reasons, most fire pipe boilers are constructed as “package” boilers (factory-assembled) for all fuels.

Water Pipe Boiler (Water Tube Boiler)

In this boiler that flows inside the pipe is boiler water, while the nasal gases are outside the pipe. At present, the water pipe boilers are more rapidly developing. In the water pipe boiler, water is fed by the boiler through pipes into the drum. Circulated water is heated by the combustion gas to form a steam pad in the drum.

Fire Pipe Combined boiler and Water Pipe.

In this boiler, there are two types of pipes, namely fire pipes and water pipes. The construction is generally like the boiler Schots. And it seems that this boiler is made to correct the deficiencies found in the Schots boiler, such as the poor circulation of water in the boiler.
