design the condensers if heat load due to sensible heat transfer in each unit about 25% of latent heat transfer. Otherwise, it is convenient to design separate de-superheater and sub-cooling exchangers. The calculations for detail study can be found out in reference [3] (page 283-285). Figure 1.9. Condensation with de-superheating and sub

The boiler system comprises of: a feed water system, steam system and fuel system. The feed water system provides water to the boiler and regulates it automatically to meet the steam demand. Various valves provide access for maintenance and repair. The steam system collects and controls the steam produced in the boiler. Steam is directed

They were the first to patent their boiler design, which used tubes inside a firebrick-walled structure to generate steam, in 1867, and they formed Babcock & Wilcox Company in New York City in 1891. Their first boilers were quite small, used lump coal, fired by hand, and operated at a very low rate of heat input.

pitting can result with possible rupture of boiler condensate piping or boiler tubes. 3.3.4 Rusty water in the boiler gage glass is a sure sign of acid corrosion in the boiler feedwater/condesate system or in the boiler itself. 3.3.5 Make-up water is the major source of carbon dioxide. The first priority is to minimize the amount of make-up water.

As a result, the furnace of a stoker fired boilers will be designed differently from that of the latter two boilers. Even PC and CFB boilers vary in design considerations as the thermal and hydrodynamic conditions in a CFB boiler are different from those of a PC boiler.

However, Section I gives no explicit indication of what constitutes a reasonably long design life. Sometimes, the criteria used to establish allowable design stresses at elevated temperature are mistakenly assumed to imply a limited design life of only 100,000 hr (about 14 yr if the boiler is in service 80% of the time).
