BOILER CHEMICAL TREATMENT PROGRAM

What is a Boiler?

A boiler generates steam and is used to generate electricity, air conditioning systems, driving steam engines, process water and many other applications.

Boiler Types and Classification:

There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler." Boilers that operate higher than 15 psig are called "high-pressure" boilers.

Fire-tube Boilers

In fire-tube boilers, combustion gases pass through the inside of the tubes with water surrounding the outside of the tubes. The advantages of a fire-tube boiler are its simple construction and less rigid water treatment requirements. The disadvantages are the excessive weight-per-pound of steam generated, excessive time required to raise steam pressure because of the relatively large volume of water, and inability to respond quickly to load changes, again, due to the large water volume.

The body of the boiler is the pressure vessel and contains the fluid. In most cases, this fluid is water that will be circulated for heating purposes or converted to steam for process use.

Water-tube Boilers

In a water-tube boiler, the water is inside the tubes and combustion gases pass around the outside of the tubes. The advantages of a water-tube boiler are a lower unit weight-per-pound of steam generated, less time required to raise steam pressure, a greater flexibility for responding to load changes, and a greater ability to operate at high rates of steam generation. A water-tube design is the exact opposite of a fire-tube. Here, the water flows through the tubes and is encased in a furnace in which the burner fires. These tubes are connected to a steam drum and a mud drum. The water is heated and steam is produced in the upper drum. Large steam users are better suited for the water-tube design. The industrial water-tube boiler typically produces steam or hot water primarily for industrial process applications, and is used less frequently for heating applications.

Why Boiler Treatment is required?

We cannot afford to lose steam production due to Boiler shut down. Its always recommended to treat and maintain Boiler using complete treatment program. In order to have prolong life of Boiler system, continuous generation of quality steam & heat supply, Boiler must be treated to get rid of corrosion & scale.

A successful boiler operation can be accomplished with 4 stages of treatment:

AKWT has plenty of experience in operation and maintenance of steam Boiler with many references available all over GCC. We have full range of quality chemicals for all types of Boilers from ANCO INDIA CHEMICALS with technology made available from ANDERSON CHEMICALS CO. USA.
