Feed Water and Steam Circuit of Boiler | Electrical4U

Mar 04, 2020 · Water Tubes. These are also essential for feed water and steam circuit of boiler Water tubes are bent or straight hollow tubes through which steam water mixture circulates. There are two types of water tubes, viz. down-comer and riser. This down comer, riser assembly is also known as Evaporator (or boiler proper).

Water-tube boiler - Wikipedia

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.

High Pressure Boilers | Powertherm | Manufacturer | Water

High Pressure Boiler | Water Tube Boiler High Pressure Boilers Working. Before converting to steam, water circulates multiple times from shell (water drum) to water tubes and then back to shell. During the circulation, the temperature of water increases as it comes in indirect contact with flue gases that transfer heat through tubes.

Water Tube Boilers | Spirax Sarco

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.

The Boiler Circulatory System: Beyond the Steam-Generating

The water/steam then rises through the wall tubes (natural thermal circulation) until it reaches the upper water wall headers. The temperature of the water/steam has by this time reached 688ºF. Riser tubes, so named for the water/steam rising from the upper water headers, take the 688ºF water/steam back to the steam drum.

What is a downcomer in a boiler? - Quora

Aug 04, 2018 · In a vertical tube water- tube boilers, risers and downcomers are used to maintain internal boiler circulation using a convection type of circulation. The water drums are located below in- way of the furnace. As the water in the water drums below get heated up, the heated mixture of water and steam rises up to the steam drum above through risers.

Water tube boilers as SCHNEIDER-Eckrohrkessel in corner tube

The steam-water mixture, which is generated in the riser tubes (7) and bottom tubes (3) rises into the unheated upper collector (4) where an almost complete separation of steam and water occurs (principle of gravity). The separated steam flows over the overflow tubes (5) into the drum area behind the partition wall (9) above the
