Steam Boiler Flooding & Surging Causes & Repairs

The bottom drain line on your boiler usually has two valves: a gate valve and a knife valve. The proper way to bottom blowdown a boiler is to start with both valves fully closed. Start by opening the knife valve, then completely open and then close the gate valve. Do this to both front and back drain valves if your boiler is so equipped.

If the ambient air is always dry, the boiler can remain open. However, if humidity and dew points get high, then the boiler should be closed. Before closing the boiler, place moisture-absorbing material such as silica gel or lime (also called unslaked lime, quick lime, calcium oxide, burnt lime, calx, and caustic lime) in the waterside and fireside.

Failure investigation of super heater tubes of coal fired

Oct 01, 2017 · Failure of super heater tube of boiler is the major concern of forced outages at coal fired thermal power plant. Flue gas passes over super heater tubes leading to damage over the time of operation and termed as fireside damage/corrosion. Again the extent of damage is dependent on quality of coal, materials used, operation and maintenance.

Coal-Fired Boiler - an overview | ScienceDirect Topics

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).
