Boiler Efficiency - an overview | ScienceDirect Topics

Sulfite residual limits are a function of boiler operating pressure. For most low- and medium-pressure systems, sulfite residuals should be in excess of 20 ppm. Hydrazine control is usually based on a feedwater excess of 0.05-0.1 ppm.

Thermal Considerations in Boiler Tube Failures

As unit pressure decreases, so does the saturation temper- ture. For a 2068 KPa (300 psig) boiler, saturation steam temperature is 1570C (3150F) and normal metal temperature may be as low as 17 IOC (34009. Under these conditions, deposit thickness may be more than 0.75 mm (30 mils) before metal temperature reaches 427 oc (80009.

What are the code requirements for the discharge piping

Mar 15, 2017 · When entering a boiler for service or repair, authorized boiler repair workers should treat the vessel as a permit-required confined space. When the boiler is shut down for repair, all sources of energy should be isolated using approved Lockout/Tagout procedures and residual pressure in steam, water, and fuel lines should be relieved by following proper bleed and block or capping procedures.
