Feb 12, 2021 · 25-A boiler steam drum safety valve lifts at 115 kg/cm2 and reseats at 110 kg/cm2, then calculate its. Blow down percentage? Blow down of safety valve = (Set pressure – Reseat pressure) X 100/Set pressure = (115 – 110) X 100/115 = 4.5% Viva Questions & answers for preparation of BOE exam & interviewGet Price
Boiler feed pumps are also referred to as feed pumps (see Reactor pump) and designed as multistage radial flow pumps. (Also see Multistage pump.) They serve to feed a steam generator such as a boiler or a nuclear reactor with a quantity of feed water corresponding to the quantity of steam emitted. Today, all boiler feed pumps are centrifugal pumps. The design of boiler feed …Get Price
The heated water then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In large utility boilers water-filled tubes form the walls of the furnace to generate steam and saturated steam coming out of the boiler drum re-enter the furnace through a superheater to become superheated. The superheated steam is used in Get Price
The other type is a water tube steam boiler. It is just the opposite of the fire tube steam boiler; the water is in the inside of the tubes and the hot gases are on the outside of the tubes. In the fire tube boiler, we have a limitation on the combustion chamber diameter and length, and it cannot exceed a certain value.Get Price

Feb 19, 2015 · The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam. (normally below 30 barg due to drum plate thickness limits ) fire tube boilers are Get Price
In some steam drum designs, water level is extremely critical because the baffling may isolate a generating section of the boiler when the steam drum water level falls below a certain point. Thin-lipped bursts also occur in superheater tubes when steam flow is insufficient, when deposits restrict flow, or when tubes are blocked by water due to Get Price

Much is flashed off with the steam; the remainder can attack boiler metal. The point of attack varies with boiler design and feedwater distribution. Pitting is frequently visible in the feedwater distribution holes, at the steam drum waterline, and in downcomer tubes. Oxygen is highly corrosive when present in hot water.Get Price
