ANALYSIS OF BOILER EFFICIENCY- CASE STUDY OF THERMAL POWER STATIONS 1.0 INTRODUCTION Looking to the statically data, rate which power demand increases is extremely very high compared to the rate at which generation capacity increase. Boiler is a heart of power plant, so its efficiency is directly affected to the all over efficiency of the plant.
energy plant, boilers often are expected to last for the life of the facility for which they are purchased. Hospitals, therefore, • Boilers produce steam for equipment sterilization and hot water for cooking, dishwashing, domestic hot water heating, • Add chemical treatments, clarifiers, and filters to help eliminate impurities
In a thermal power plant, a turbine is rotated with the help of motive steam at a very high temperature ( 540 deg. C). That turbine in turn acts as the armature of an electrical generator and hence electricity is produced . To produce steam, large

Boiler Water Treatment Chemicals, Feed, and Control - Perhaps It Is More Complicated Than We Thought - Dave Christophersen CROWN Solutions, Inc. September 15, 2006 Chemicals used to treat steam boiler systems are applied based upon the demand and mode of reaction of each chemical used.
Steam Production From steam tables we can see that the total heat of steam does not vary a great deal as the boiler pressure increase The boiling point (b.p.) increases as the pressure increases Thus the sensible heat increases as the pressure increases, and the latent heat decreases Boiler pressures are expressed in psia, psig, bar, kg/cm2
The boiler in a coal-fired power plant converts chemical energy contained within the coal into heat energy that is captured and carried away in hot, high-pressure steam (Figure 3.2). Coal-burning technology has a long history and has seen many plant configurations, but the most important type of plant in modern use is the pulverized coal-fired
The Electric Power Research Institute's (EPRI's) Boiler and Turbine Steam and Cycle Chemistry Program (Program 64) offers guidelines, technology, and training materials to help plant operators manage water-steam chemistry, reduce unplanned outages and operations and maintenance (O&M) costs, and improve unit economics. Research Value
Boilers are also crucial in Power Generation plants or Co-Generation Plants where you use steam turbines to generate electricity. The steam or hot water is heated by passing water either through tubes (Water Tube) or around tubes that are heated by a flame (Fire Tube and Scotch Marine). The flame is created by burning some type of fuel.
Best Operating Practices for Boiler Blowdown As mentioned earlier, insufficient blowdown may cause carryover of boiler water into the steam or the formation of deposits on boiler tubes. Excessive blowdown wastes energy, water and treatment chemicals. The blowdown amount required is a function of boiler type, steam pressure, chemical
A deaerator energy balance then can be developed to determine deaerator steam usage and other energy data needed for a critique of the entire steam system (Figure 4). After establishing condensate return and deaerator steam usage per thousand pounds of steam produced, an overall energy balance of the boiler can be developed.
Water and steam are the lifeblood of any steam-driven power facility, and proper chemistry control is critically important to plant operation, reliability, the bottom line, and especially
Boiler water quality is of prime concern to all boiler operators. The process of water treatment in boilers is not limited to producing high quality DM water. The stringent water chemistry requirements of Supercritical power plants makes water treatment in boilers a very critical aspect of power plant operation. This necessitates the use of a high quality water treatment system.

Silica needs to be controlled at DM plant also. The percentage of impurity allowed in boiler water/steam is function of boiler operating pressure, so, more critical for high pressure boilers. Two basic ways to regulate corrosion in water, are All Volatile Treatment (AVT) and Oxygenated Treatment (OT).
Ibrahim Dincer, Marc A. Rosen, in Exergy (Second Edition), 2013. 12.1 Introduction. Steam power plants are widely utilized throughout the world for electricity generation, and coal is often used to fuel these plants. Although the world's existing coal reserves are sufficient for about two centuries, the technology largely used today to produce electricity from coal causes a significant

Several investigations were conducted on energy and exergy optimization of chemical industrial factories. Ray et al.  developed an exergy analysis for proper operating and maintenance decisions in a 500 MW steam power plant.
Clean boiler heat transfer surfaces to remove the soot buildup that acts like an insulator and diminishes the efficiency of heat transfer between combustion gas and steam generation. Heat loss from a boiler can waste a huge amount of energy. To minimize heat loss, install an economizer to recover waste heat from the stack.
Knowing the Cost of Steam C.Percentage of make-up water or percentage of condensate return Normal condensate returns have a higher Btu content than make-up water. Today's industrial benchmark for condensate return is 90% if the plant is not injecting steam for the process. D. fi eBflecrienocyi Higher boiler efficiency lowers steam cost
