【摘要】：集中供熱系統(tǒng)是現(xiàn)代化城市重要的基礎(chǔ)設(shè)施，不僅能給城市提供穩(wěn)定、可靠的熱能，改善人民生活環(huán)境，而且能夠節(jié)約能量、減少城市污染。熱電聯(lián)產(chǎn)在城市現(xiàn)代化建設(shè)的進程中，尤為顯著的表現(xiàn)在環(huán)保節(jié)能、符合國家可持續(xù)發(fā)展戰(zhàn)略，在推動能源與環(huán)境協(xié)調(diào)發(fā)展，改善冬季供熱狀況等方面發(fā)揮著重要作用。 本文首先根據(jù)新疆K縣城近、遠期發(fā)展規(guī)劃，結(jié)合K縣城的地域特點，分析不同建筑物的功能和供熱要求，得出K縣城近、遠期的設(shè)計供暖總熱負荷這一重要基礎(chǔ)數(shù)據(jù)；其次，結(jié)合K縣城的城市總體規(guī)劃和熱負荷分布狀況，研究分析集中供熱系統(tǒng)的熱源、熱媒、熱力站和熱網(wǎng)，經(jīng)過論證不同方案，獲得K縣城的集中供熱可行性方案；然后，通過對總熱負荷和項目所在地概況分析，確定熱源形式，并進行對熱網(wǎng)的水力計算和熱力站的規(guī)劃與設(shè)計，提出換熱器和循環(huán)水泵等主要設(shè)備的設(shè)計參數(shù)和選型方案；最后，對熱電聯(lián)產(chǎn)集中供熱、鍋爐房集中供熱和分散供熱的耗煤量和排放物進行了對比，闡述了熱電聯(lián)產(chǎn)集中供熱所帶來的經(jīng)濟效益和環(huán)境效益。 本文針對K縣城的具體特點，應(yīng)用供熱工程理論，提出適合于K縣城的科學(xué)合理的供熱方案，有望極大改善K縣城的供熱質(zhì)量，，提高供熱系統(tǒng)的能量利用率，實現(xiàn)更好的經(jīng)濟效益、環(huán)境效益和社會效益。
[Abstract]:Central heating system is an important infrastructure in modern cities. It can not only provide stable and reliable heat energy to the city and improve people's living environment, but also save energy and reduce urban pollution. In the process of urban modernization, heat and power cogeneration plays an important role in promoting the coordinated development of energy and environment, improving the situation of heating in winter and so on, especially in the process of environmental protection and energy saving, in line with the national sustainable development strategy. According to the near and long term development plan of K county in Xinjiang and the regional characteristics of K county, this paper analyzes the functions and heating requirements of different buildings, and obtains the important basic data of the design total heat load of the near and long term heating in K county. According to the overall urban planning and the distribution of heat load in K county, this paper studies and analyzes the heat source, heat medium, thermal station and heat network of the central heating system. Through the demonstration of different schemes, the feasible scheme of central heating in K county is obtained. Through the analysis of the total heat load and the site of the project, the form of the heat source is determined, and the hydraulic calculation of the heat network and the planning and design of the thermal station are carried out, and the design parameters and the selection scheme of the main equipment, such as heat exchanger and circulating water pump, are put forward. The coal consumption and emissions of cogeneration central heating boiler room and decentralized heating are compared and the economic and environmental benefits brought by cogeneration heating are expounded. According to the specific characteristics of K county, applying the theory of heating engineering, this paper puts forward a scientific and reasonable heating scheme suitable for K county, which is expected to greatly improve the heating quality of K county and increase the energy utilization ratio of the heating system. To achieve better economic, environmental and social benefits.
