Utility power generation

Bolton, H. R. and Ray, N. J., Non-Utility Power Generation Steam Plant. Inst. Mech. Eng. (1989)... 

Very large, modem WT boilers with sophisticated heat-recovery auxiliaries may attain efficiencies approaching 88 to 90%. However, the overall efficiency of a fossil fuel utility power generation plant system falls to only 32 to 38% when the efficiency of electricity generation and condenser cooling is included. Nevertheless, it only requires 10% more in fuel costs to operate a boiler at 1,250 psig than... 

The first three boiler types may be variously used for commercial, institutional, or industrial applications. Fire tube boilers also may be used for steam turbine generator duty at lower electrical outputs, whereas only WT and nuclear reactor boilers are employed for utility power generation. 

Radiant power boilers are two-phase boilers. Designs typically employ only one drum for the largest installations, whereas smaller power boiler designs generally incorporate two drums. Fossil fuel-fed, radiant power boilers are probably the most common type of equipment employed for large-scale utility power generation. 

Although the complexity of operating an average industrial boiler plant (with perhaps only two or three FT boilers) cannot be compared to that of a large utility power generating station, the potential for waterside problems, while different, may be just as difficult to control. As an example, consider some differences between a utility and a factory.

For example, in some very specialized areas of boiler water treatment (such as nuclear power units and especially utility power generation), there is probably little or nothing of any practical value that service companies can teach the current practitioners.

Section 112(n)(l)(A) of the amended CAA directed EPA to evaluate the health hazards associated with emissions of hazardous air pollutants (HAPs) from electric utility power generating units that used fossil fuels. HAPS identified for further evaluation included lead, out of a screening list of 67 substances. 

Many large-diameter pipelines owned by public utilities, power generation facilities, and industrial sites are located in areas where any excavation is challenging or undesirable. For these types of limited access pipes, and especially in cases where targeted repairs of distressed pipes are to take place, the use of carbon fiber-reinforced polymer (CFRP) lining becomes the most cost-effective and efficient repair or upgrade solution.
