Carry Over From Boiler Drum - Bright Hub Engineering

10/10/2009 · Carry over from drum can be of two types: mechanical carry over and vaporous carry over. The carryover from boiler drum results in deposits in the internal surface of superheater tubes leading to overheating failures. It also results in deposit in turbine blades which reduces the turbine efficiency. Mechanical carry over take place in a boiler mainly due to drum internals; drum level, foaming

Power Plant Boiler Steam Drum Water Drum

A steam drum is a standard feature of a water-tube boiler: The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture. The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water/and saturated-steam into the steam-drum.

18/9/2019 · The T.B. Simon power plant is typical of many such cogeneration plants used within universities. The boiler consists of gas-fired water tubes leading to the steam drum above. The drum holds both steam and water at approximately 400 F and 900 psi. From the

Steam drums for power generation | Magnetrol

Steam drums for power generation. The steam drum is the primary interface between water and steam. In a coalfired plant, boiler feedwater passes through the economizer and into the drum where the steam separates from the feedwater and is drawn off to the superheater. In combined-cycle operations, a Heat Recovery Steam Generator (HRSG) serves the

Dynamic Shrink/Swell and Boiler Level Control – Control …

Since, the net steam draw rate has gone up, the net flow of water to the boiler needs to increase, because the total mass of water in the boiler is falling. However, the level controller senses a rise in the level of the steam drum and calls for a reduction in the flow of feedwater to the boiler.
