摘要

电力和热能的联合生产(CHP或热电联产)是降低工业发电厂和区域供热厂能源成本的最有效和最方便的方法,这些发电厂使用天然气作为燃料来生产满足各种需求的热能。本文分析了作为贝尔格莱德区域供热系统一部分的Vozdovac供热厂自2021年1月1日开始运行的热电联产电厂的运行特点。该热电联产电厂由三台燃气发动机机组组成,总标称功率为10兆瓦,热功率为10.1兆瓦,使用天然气作为燃料。热电联产厂用于区域供热和制备生活热水(DHW),而电力则出售给当地电网。本文着重分析了该装置的运行特点:工作小时数、总能耗和能源产量、效率以及运行和维护成本。此外,还特别分析了去年天然气价格、电力价格和维护成本的急剧变化对热电联产电厂财务盈利能力的影响。

Operational characteristics of the CHP plant in the district heating system of Belgrade
The combined production of electricity and thermal energy (CHP or cogeneration) is the most efficient and convenient approach to reduce costs for energy at industrial power plants and district heating plants that use natural gas as fuel to produce thermal energy for various needs. This paper analyses the operational characteristics of the CHP plant, which has been operating since January 1, 2021, at the Vozdovac Heating Plant as part of the Belgrade district heating system. The CHP plant consists of three gas engine units with a total nominal electric power of 10 MW and thermal power of 10.1 MW, which use natural gas as fuel. The CHP plant is used for district heating and preparing domestic hot water (DHW) while electricity is sold to the local electric grid. The analysis in this paper focuses on the plant's operational characteristics: the number of working hours, the total energy consumption and energy production, the efficiency as well as the operational and maintenance costs. Also, the impact of the drastic changes in the prices of natural gas, electricity, and maintenance costs in the last year on the financial profitability of the CHP plant was analysed in particular.

期刊介绍: The main aims of Thermal Science to publish papers giving results of the fundamental and applied research in different, but closely connected fields: fluid mechanics (mainly turbulent flows), heat transfer, mass transfer, combustion and chemical processes in single, and specifically in multi-phase and multi-component flows in high-temperature chemically reacting flows processes present in thermal engineering, energy generating or consuming equipment, process and chemical engineering equipment and devices, ecological engineering, The important characteristic of the journal is the orientation to the fundamental results of the investigations of different physical and chemical processes, always jointly present in real conditions, and their mutual influence. To publish papers written by experts from different fields: mechanical engineering, chemical engineering, fluid dynamics, thermodynamics and related fields. To inform international scientific community about the recent, and most prominent fundamental results achieved in the South-East European region, and particularly in Serbia, and - vice versa - to inform the scientific community from South-East European Region about recent fundamental and applied scientific achievements in developed countries, serving as a basis for technology development. To achieve international standards of the published papers, by the engagement of experts from different countries in the International Advisory board.
