Boiler Gauge Glass Blow Down Procedure. Here are the steps that you will follow, when blowing down the boiler gauge glass: 1) Make sure that you have worn the protective gear like goggles and gloves. 2) Shut the steam, and water cock for the gauge glass, 3) Drain it by opening it slowly.

A sight glass or water gauge is a type of level sensor, a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within.

Boilers operating at lower pressures will have the more simple single tubular type gauge glass. Boilers operating at higher pressures (typically > 33 bar) will utilize double plate type boiler gauges. Water tube boilers in power stations will always have double plate boiler gauge glasses due to their high temperature and pressure operating conditions. Safety Aspect. It is standard practice for larger boilers to have a …

Figure 3.7.10 shows a typical gauge glass. Gauge glasses are prone to damage from a number of sources, such as corrosion from the chemicals in boiler water, and erosion during blowdown, particularly at the steam end. Any sign of corrosion or erosion indicates that a new glass is required. When testing the gauge glass steam connection, the water

Oct 25, 2019· It is on the basis of the boiler pressure that the construction of the gauge glass is decided.

Boiler Level Gauges are used as a boiler mounting of all types of high and low pressure boilers to indicate the boiler water level which is critical and they are often used as Right hand and Left Hand in pairs.Boiler Level Gauges are used along with Auto-Shut-Off-Ball-Check-Valves with union bonnet or bolted bonnet design.There are basically three types as given below:-

The three standard types of gauge glass are listed: Type A, Plain is designed for moderate-pressure steam boilers and liquid level indicators. Type A, High Pressure is controlled to tighter flatness tolerances to be used in higher pressure applications. Type B, Reflex is made for ease in determining liquid levels, especially in clear fluids.
