The steam cock 1 keeps the glass in connection with the steam space and cock 2 puts the glass tube in connection with the water space in the boiler. The drain cock 3 is used to drain out the water from the glass at intervals to ascertain that the steam and the3.

Read MoreWhen steam demand from the plant is low, and the boiler is capable of generating more steam than is required, the surplus steam is injected into a mass of water stored under pressure. Over a period of time the stored water content will increase in temperature and pressure until it finally achieves the saturation temperature for the pressure at which the boiler is operating.

Read More26/6/2015 · Steam stop valve A valve is a device that regulates the flow of a fluid (gases, fluidized solids slurries or liquids) by opening or closing or partially obstructing various passageways Function : to shut off or regulate the flow of steam from the boiler to the steam pipe or steam from the steam pipe to the engine. 26. Steam stop valve. 27.
Read MoreFor example, a steam drum that is operating at normal water level has the bottom half of the drum cooled by water and the top half by air initially and steam eventually. If one starts to fire the boiler from a cold start, the water will heat up very quickly in the drum and the bottom half of the drum will expand much more quickly than the top half which is not in contact with water.
Read MoreIf the steam cools and condenses back into water droplets, that water can drain from the steam drum to the feedwater drum via the downcomer tube. This allows that water to re-enter the boiler's water supply, go back into the tubes, and once again be turned into useful steam.
Read More6/4/2020 · This boiling water ultimately becomes steam that can then be released by the boiler to be used for heating and other purposes. The process from a cold start to full steam typically takes minutes, rather than hours. Water-tube boilers also have a downcomer tube that connects the …
