What is the function of water level indicator in boiler?

The function of a water level indicator is to indicate the level of water in the boiler constantly. It is also called water gauge. It helps the operator in keeping the level constant from outside through a glass tube. In case of need, if the level falls down, water will be pumped by the operator.

How do I check the water level in my boiler?

All steam boilers must have two means to determine water level. The gauge glass is the first and easiest means. A second device is the try cocks, a valve located on the water column used to determine the water level if the gauge glass is not functional.

What type of level indicator is installed in boiler?

A level indicator, whether it be a gage glass, indirect sensing method, or independent remote, is used on a steam boiler to provide a water level reading. A gage glass is the most common form of level indicator found on steam boilers.

Why is water level gauges in a boiler so important?

The water level gauge provides a visible indication of the water level in a boiler in the region of the correct working level. If the water level were too low then the heat transfer surfaces might become exposed to excessive temperatures and fail. Constant attention to the boiler water level is therefore essential.

How many water level indicators are in a boiler?

Normally two water level indicator are fitted into the boiler.

What is the principle of water level indicator?

Principle of Water Level Indicator. The working principle of a water level indicator is actually quite simple. Water level indicators work by using sensor probes to indicate water levels in a storage tank. These probes send information back to the control panel to trigger an alarm or indicator.

How do I manually add water to my boiler?

When the boiler has cooled down, locate the feed water pipe. This can be found off the cold water line, connecting to the pipe that leads to the tank. Open the feed water valves carefully. Keeping an eye on the sight glass, slowly pour in clean water until it meets the right level mark.

Why mounting are essential in boiler?

Boiler mountings are a set of safety device installed for the safe operation of a boiler. These equipment save the boiler from damage due to extreme pressure, steam back flow, shell collapse due to vacuum, unregulated steam pressure, low water level, back flow of feed water to the pump and dry running respectively.

What causes low water level in boiler?

Some of the common causes include: Feedwater pump failure. Control valve failure. Loss of water to the deaerator or make-up water system.

How can you tell the water level in a boiler?

The water in the tube showed the water level in the boiler. A drain cock below the lower guage cock, allowed the blowing through of either guage cock with the other turned off to make certain that neither end of the tube was choked with scale or impurities, such that a false water level was indicated.

How is the design of a boiler determined?

Boiler design may be based upon: Quality of raw water : how hard or soft the water is will determine the material of the boiler. Heat source – the fuel to be burned and its ash properties or the process material from which the heat is to be recovered.

What do you need to know about the Indian boiler Act?

Accessories help in controlling and running the boiler efficiently. Certain common mountings (specifically those required by the Indian Boiler Act) include: Feed check valve – regulates the flow of water into the boiler and prevents the back flow of water in case of failure of the feed pump.

What does the bottom blowdown valve on a boiler do?

Water level indicators: They show the operator the level of fluid in the boiler, also known as a sight glass, water gauge or water column. Bottom blowdown valves: They provide a means for removing solid particulates that condense and lie on the bottom of a boiler.
