The document describes the key components of a steam power plant, including:
1. The coal handling plant which includes unloading, conveying, and crushing coal.
2. The boiler, which uses water tubes or fire tubes to generate high pressure steam.
3. Turbines which convert the thermal energy of steam into rotational motion using impulse or reaction blades.
4. Condensers which cool the steam from the turbines before it returns to the boiler via feed pumps to repeat the Rankine cycle that powers the plant.

Thermal Power Plant or Thermal Energy (Chapter-2)Tesfaye Birara
Energy conversion is the process of changing one form of energy into another, a fundamental capability that enables modern civilization to function. It can occur in various ways, from converting the kinetic energy of wind into mechanical power through windmills to transforming solar energy into electrical energy in solar panels. This transformation is essential not just for daily usage but also for harnessing and utilizing natural resources more efficiently. In the context of rural electrification, this process plays a critical role. By converting available local energy resources into electricity, rural communities can access a stable and reliable power supply. This not only improves the quality of life but also supports economic development by powering homes, schools, businesses, and healthcare facilities. Consequently, energy conversion facilitates the broader goal of rural electrification, demonstrating the interconnection between technological innovation and societal advancement.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

16. Boiler Accessories
Economizer
The first successful economizer
design was used to increase the
steam-raising efficiency of the
boilers of stationary steam
engines. It was patented by
Edward Green in 1845.
•Economizers are commonly used
as part of a heat recovery steam
generator in a combined cycle
power plant.
• A common application of
economizers in steam power plants
is to capture the waste heat from
boiler stack gases (flue gas) and
transfer it to the boiler feed water.
This raises the temperature of the
boiler feed water

Re-heater
Re-heaters are the same as the super-heaters but the temperature of
it’s a little bite less than super-heaters and their pressure is 20%-
25% less than the super-heater,
It usually use to elevate the steam temperature. After expanding
through the high pressure turbine the exhaust steam is returned to the
boiler at 360 C and 42 bar pressure for reheating before being used in
the intermediate pressure turbine.
The re-heater reheats the steam from a temperature of 360 C back to
568 C.

66. Rankine Cycle
• Basic Cycle
• The Rankine cycle is the fundamental operating cycle of all power plants where an operating
fluid is continuously evaporated and condensed. The selection of operating fluid depends
mainly on the available temperature range. Figure 1 shows the idealized Rankine cycle.
• The pressure-enthalpy (p-h) and temperature-entropy (T-s) diagrams of this cycle are given
in Figure 2. The Rankine cycle operates in the following steps:
• 1-2-3 Isobaric Heat Transfer. High pressure liquid enters the boiler from the feed pump (1)
and is heated to the saturation temperature (2). Further addition of energy causes evaporation
of the liquid until it is fully converted to saturated steam (3).
• 3-4 Isentropic Expansion. The vapor is expanded in the turbine, thus producing work which
may be converted to electricity. In practice, the expansion is limited by the temperature of the
cooling medium and by the erosion of the turbine blades by liquid entrainment in the vapor
stream as the process moves further into the two-phase region. Exit vapor qualities should be
greater than 90%.
• 4-5 Isobaric Heat Rejection. The vapor-liquid mixture leaving the turbine (4) is condensed at
low pressure, usually in a surface condenser using cooling water. In well designed and
maintained condensers, the pressure of the vapor is well below atmospheric pressure,
approaching the saturation pressure of the operating fluid at the cooling water temperature.
• 5-1 Isentropic Compression. The pressure of the condensate is raised in the feed pump.
Because of the low specific volume of liquids, the pump work is relatively small and often
neglected in thermodynamic calculations.
