【摘要】：天然氣分布式能源站(Natural Gas Distributed Energy Station)作為能源領(lǐng)域的一個(gè)清潔、高效、便利的綜合性項(xiàng)目,近年來逐步由歐美發(fā)達(dá)國(guó)家引入國(guó)內(nèi)。隨著能源消耗的不斷增加,能源成本不斷上升,環(huán)境保護(hù)壓力的逐步加大,在工業(yè)高速發(fā)展的情況下,工業(yè)園區(qū)對(duì)燃料和用能系統(tǒng)的清潔高效性依賴也越來越高。工業(yè)園區(qū)用能結(jié)構(gòu)的合理性和能源利用率的高低將直接影響我國(guó)能源結(jié)構(gòu)的發(fā)展方向。因此,在工業(yè)園區(qū)制定經(jīng)濟(jì)合理、安全可靠的用能形式是解決上述問題的關(guān)鍵。首先,分析了NGDES在國(guó)內(nèi)外的發(fā)展趨勢(shì),結(jié)合濟(jì)南的能源供應(yīng)現(xiàn)狀和供應(yīng)條件并響應(yīng)節(jié)能環(huán)保的政策要求,確定采用NGDES替代原有燃煤鍋爐為工業(yè)園區(qū)供能。并且對(duì)NGDES的概念、系統(tǒng)分類、原理和主要設(shè)備進(jìn)行了介紹。其次,課題選用濟(jì)南某工業(yè)園的煤改氣工程實(shí)例進(jìn)行研究。根據(jù)現(xiàn)場(chǎng)調(diào)研和園區(qū)提供的冷、熱、電負(fù)荷數(shù)據(jù),結(jié)合濟(jì)南市典型年室外氣象參數(shù),模擬推算了濟(jì)南某工業(yè)園的工業(yè)用蒸汽負(fù)荷、供暖用熱負(fù)荷、夏季冷負(fù)荷以及全年電負(fù)荷,并詳細(xì)分析了各用能建筑的負(fù)荷特點(diǎn)。工業(yè)園年供蒸汽量是10萬噸,其中有4.012萬噸用于滿足冬季供暖負(fù)荷,5.76萬噸用于滿足生產(chǎn)工藝用蒸汽負(fù)荷,2280噸用于吸收式制冷,年供冷量是2844MW,年耗電量是2479萬kWh。根據(jù)各負(fù)荷特點(diǎn)設(shè)計(jì)了6種可供選擇的NGDES系統(tǒng)和相關(guān)的設(shè)備,確定使用燃?xì)廨啓C(jī)發(fā)電機(jī)組作為原動(dòng)機(jī)組,采用余熱鍋爐作為余熱回收設(shè)備以提高系統(tǒng)的綜合能源利用率,采用燃?xì)忮仩t作為補(bǔ)燃設(shè)備,尤其是滿足冬季供暖用蒸汽熱負(fù)荷需求。并研究了各方案合理的運(yùn)行模式,選擇最優(yōu)系統(tǒng)保證系統(tǒng)能夠以最佳狀態(tài)運(yùn)行,以達(dá)到節(jié)能環(huán)保的要求。最后,對(duì)濟(jì)南某工業(yè)園分布式能源站進(jìn)行了實(shí)際監(jiān)測(cè),并對(duì)監(jiān)測(cè)數(shù)據(jù)進(jìn)行了研究分析。并且使用系統(tǒng)綜合能源利用率、?效率、經(jīng)濟(jì)?效率、相對(duì)節(jié)能率等指標(biāo)綜合評(píng)價(jià)了分布式能源站系統(tǒng)。根據(jù)現(xiàn)場(chǎng)實(shí)測(cè)的數(shù)據(jù)重點(diǎn)分析系統(tǒng)的環(huán)境效益、經(jīng)濟(jì)效益和社會(huì)效益。
[Abstract]:As a clean, efficient and convenient comprehensive project in the field of energy, Natural Gas distributed Energy Station has been gradually introduced into China by developed countries in Europe and America in recent years. With the increasing of energy consumption, the energy cost is rising, and the pressure of environmental protection is gradually increasing. With the rapid development of industry, the industrial park relies more and more on the cleanliness and efficiency of fuel and energy use system. The rationality of energy use structure and the efficiency of energy utilization in industrial parks will directly affect the development direction of energy structure in China. Therefore, it is the key to solve the above problems to make a rational, safe and reliable energy use form in the industrial park. Firstly, the development trend of NGDES at home and abroad is analyzed. According to the current situation and supply conditions of energy supply in Jinan, and in response to the policy requirements of energy saving and environmental protection, NGDES is adopted to replace the original coal-fired boilers to supply energy for the industrial park. The concept, system classification, principle and main equipment of NGDES are introduced. Secondly, the project selected Jinan industrial park coal to gas project case study. Based on field investigation and data of cold, heat and electricity load provided by the park, combined with outdoor meteorological parameters of typical years in Jinan, the industrial steam load, heating heat load, summer cooling load and annual electric load of an industrial park in Jinan are simulated and calculated. The load characteristics of energy-using buildings are analyzed in detail. The annual steam supply of the industrial park is 100000 tons, of which 40120 tons are used to meet the heating load in winter, and 57600 tons to meet the steam load of production process. The annual cooling capacity is 2844 MW and the annual electricity consumption is 24.79 million kWh. According to the characteristics of each load, six kinds of alternative NGDES system and related equipment are designed. The gas turbine generator unit is used as the prime mover group, and the waste heat boiler is used as the waste heat recovery equipment to improve the comprehensive energy utilization of the system. Gas-fired boiler is used as supplementary combustion equipment, especially to meet the heat load demand of heating steam in winter. The reasonable operation mode of each scheme is studied, and the optimal system is chosen to run in the best condition to meet the requirements of energy saving and environmental protection. Finally, a distributed energy station in Jinan Industrial Park is monitored, and the monitoring data are analyzed. And use the system for comprehensive energy utilization? Efficiency, economy? The distributed energy station system is evaluated synthetically by efficiency, relative energy saving rate and so on. The environmental benefit, economic benefit and social benefit of the system are analyzed according to the field measured data.
