Über dieses Buch

This book analyzes the continuous operation of a power plant with condensing power units in combined heat and power mode (CHP-mode) over a period of one year. Focusing on the operation of one and two power-unit systems with differing heat exchanger configurations, this book uses mathematical modeling of the steam-water cycle of a 370 MW power unit to calculate the operating characteristics and mass-energy balance of the system.
Featuring comprehensive thermodynamic analysis of the quasi-unsteady operation of power units in cogeneration for electrical power generation, as determined by the Polish Power System, this work also includes an economic analysis of the power plant, presenting the costs and economic effectiveness of such a system.

Chapter 1. Introduction, Objectives and Scope of Work

Abstract
The support for the development of production of electricity and heat in cogeneration has been one of the rightfully recognized aims of the energy policy of the European Union. This aim has found its reflection in the Directive 2004/8/EC of the European Parliament. The promotion of high-efficiency cogeneration involving combined heat and power production based on a balance of demand for district heating brings considerable benefits which can be achieved as a result of saving chemical energy of primary energy source (PES) (Bartnik et al. in Thermal and economic effectiveness. Springer, London, [1]). In addition, the Directive 2012/27/UE of the European Parliament dealing with energy efficiency indicates that cogeneration can form one of the sources to ensure realization of the requirements imposed by the UE in the area of energy and climate policy.

Chapter 2. Mathematical Model of the Steam–Water Cycle of 370 MW Power Unit

Abstract
Figure 2.1 presents the thermal diagram of a power unit working in cogeneration. This diagram is based on the design of a power unit with the rated capacity of 370 MW which is supplemented by a district heating part with steam bleed from A2 to A3 extractions, crossover pipe joining intermediate- and low-pressure sections, and a steam header.

Chapter 3. Operation of a Condensing Power Plant with Power Units with the Rated Capacity of 370 MW in Cogeneration in the System of Power and Frequency Regulation of the Polish Power System

Abstract
Cogeneration involving concurrent generation of electricity and heat forms one of the most important ways of producing energy according to principles of economy and ecology, as reflected by the Directive 2012/27/UE of the European Parliament and of the European Council from October 25, 2012. Poland is one of the countries in which the proportion of the heat production in cogenerating sources is at relatively high level in the total energy production. In 2001, it was equal to 64 % of the total heat production in the country. Although this is a considerable figure, there is still a large potential for the application of cogeneration and this process is inevitable. This is so as the commitment to reduce the emission of greenhouse gases by the Polish economy, which is based on combustion of hard coal and lignite, is extremely costly, and leads to deterioration of the condition of Poland’s economy.

Chapter 4. Economic Analysis of Quasi-Nonstationary Operation of a Condensing Power Plant with 370 MW Power Unit in Cogeneration

Abstract
The monograph (Bartnik in Thermal and economic effectiveness. Springer, London, [1]) presents two alternatives of the economic analysis of the operation of a single and two power units with the rated capacity of 370 MW in cogeneration: one for the constant operation with the electrical power output of 380 MW and the operation with a constant input of the chemical energy of the fuel corresponding to this power output in which the production of steam in the peak emergency heater XC5 is not accounted for (Fig. 2.1 in Chap. 2).
