Our Lastest Boiler Type

Seven Hold Points

Seven hold points are set and each one is supervised by a responsible inspector. Any work that fails to pass the inspection cannot proceed until the inspector is able to verify its quality.

1,Incoming materials are inspected again upon entry into the plant.

2,Material markings will be transferred to all cut pieces to ensure identification and traceability.

3,Test pieces are used to ensure a higher success rate in welding.

Steam flow through the tray stack may be cross-flow, counter-current, or co-current to the water. The deaerated water is usually stored in a separate tank, as illustrated in Figure 10-4. The spray-type deaerating heater consists of a shell, spring-loaded inlet spray valves, a direct-contact vent condenser, and a steam scrubber for final deaeration.

Deaerator - Wikiped

A deaerator is a device that removes oxygen and other dissolved gases from water, such as feedwater for steam-generating boilers.Dissolved oxygen in feedwater will cause serious corrosion damage in a boiler by attaching to the walls of metal piping and other equipment and forming oxides (rust). Dissolved carbon dioxide combines with water to form carbonic acid that causes further corrosion.

Boiler feedwater - Wikiped

Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it

The Spray-Type Deaerator consists of a horizontal or vertical cylindrical vessel which serves as both the deaeration section and the boiler feedwater storage tank. The typical spray-type deaerator is a horizontal vessel which has a preheating section and a deaeration section. The two sections are separated by a baffle.

Deaerator- What are deaerators?, working, constructio

The deaerators are normally used in any chemical process industry or in power plants where the boiler is used for the production of steam from the boiler feed water. The heating deaeration process is the separation process done by using mechanical equipment that has been designed in such a way that is used for the work process as desired.

Oxygen scavengers are added to the boiler water, preferably in the storage tank of the deaerator so the scavenger will have the maximum time to react with the residual oxygen. Under certain conditions, such as when boiler feedwater is used for attemperation to lower steam temperature, other locations are preferable.
