【摘要】：為減少區(qū)域鍋爐房電耗，一些供熱企業(yè)利用工業(yè)汽輪機代替電動機拖動熱網(wǎng)循環(huán)泵和鍋爐鼓、引風(fēng)機等負載，但是當(dāng)前工業(yè)汽輪機的使用都是無序的、無規(guī)模化的。對此，本文針對嚴寒和寒冷地區(qū)供熱規(guī)模為200萬m2~700萬m2，采用工業(yè)汽輪機拖動熱網(wǎng)循環(huán)泵、鍋爐給水泵和鼓、引風(fēng)機，，排汽用于汽水換熱實現(xiàn)能量梯級利用和“熱功聯(lián)產(chǎn)”的區(qū)域鍋爐房供熱系統(tǒng)進行技術(shù)性、經(jīng)濟性和節(jié)能性研究。從而為工業(yè)汽輪機的合理配備及選擇提供一定指導(dǎo)和參考。 首先，分析了區(qū)域熱水鍋爐房供熱系統(tǒng)形式以及區(qū)域蒸汽鍋爐房和區(qū)域蒸汽熱水鍋爐房采用工業(yè)汽輪機拖動負載，排汽用于汽水換熱實現(xiàn)能量梯級利用和“熱功聯(lián)產(chǎn)”的系統(tǒng)形式，繪制各種形式的區(qū)域鍋爐房供熱系統(tǒng)原理圖。 其次，對嚴寒和寒冷氣候區(qū)鍋爐容量和臺數(shù)的配備，鍋爐與拖動負載的配備及拖動負載用工業(yè)汽輪機與換熱器的配備策略進行了研究。得到嚴寒和寒冷地區(qū)區(qū)域鍋爐房內(nèi)鍋爐與拖動負載、工業(yè)汽輪機及汽水換熱器的配置方案，并對嚴寒地區(qū)4臺29MW~99MW和寒冷地區(qū)3臺46MW~99MW的區(qū)域熱水鍋爐房、區(qū)域蒸汽鍋爐房和區(qū)域蒸汽熱水鍋爐房進行配備。 再次，對嚴寒和寒冷地區(qū)區(qū)域鍋爐房供熱系統(tǒng)鍋爐及其熱網(wǎng)循環(huán)泵，鍋爐鼓、引風(fēng)機和給水泵的運行調(diào)節(jié)和能耗進行了研究。得到嚴寒和寒冷地區(qū)不同形式的區(qū)域鍋爐房供熱系統(tǒng)鍋爐及其拖動負載的運行調(diào)節(jié)公式和能耗公式，并對嚴寒和寒冷地區(qū)典型城市進行算例分析，得到各典型城市鍋爐與拖動負載的運行調(diào)節(jié)過程和能耗。 最后，建立區(qū)域鍋爐房供熱系統(tǒng)單位供熱面積費用年值的經(jīng)濟模型，并分析區(qū)域蒸汽鍋爐房和區(qū)域蒸汽熱水鍋爐房采用工業(yè)汽輪機拖動負載的經(jīng)濟性和節(jié)能性。以嚴寒和寒冷地區(qū)供熱面積為200萬m2~700萬m2的供熱系統(tǒng)進行案例分析，得到區(qū)域蒸汽熱水鍋爐房供熱系統(tǒng)經(jīng)濟性優(yōu)于區(qū)域蒸汽鍋爐房供熱系統(tǒng)，蒸汽鍋爐房供熱系統(tǒng)優(yōu)于熱水鍋爐房供熱系統(tǒng)；采用工業(yè)汽輪機代替電動機拖動負載，嚴寒地區(qū)可節(jié)電1.39kwh/m2~1.88kwh/m2，寒冷地區(qū)可節(jié)電0.96kwh/m2~1.36kwh/m2，考慮工業(yè)汽輪機拖動負載多耗燃煤量，嚴寒地區(qū)綜合節(jié)煤量0.06kg標準煤/(m2a)~0.18kg標準煤/(m2a)，寒冷地區(qū)綜合節(jié)煤0.05kg標準煤/(m2a)~0.09kg標準煤/(m2a)。
[Abstract]:In order to reduce the power consumption of regional boiler room, some heating enterprises use industrial steam turbine instead of motor to drive heat network circulating pump, boiler drum, induced fan and other loads, but at present the use of industrial steam turbine is disorderly and no scale. In this paper, in view of the heating scale of 2 million m ~ 2 ~ 7 million m ~ 2 in cold and cold regions, this paper adopts industrial steam turbine to drive heat network circulating pump, boiler feed water pump, drum, induced fan, etc. Exhaust steam is used to realize energy cascade utilization and "heat and power cogeneration" of regional boiler room heating system for technical, economic and energy saving research. Thus, it provides some guidance and reference for the reasonable configuration and selection of industrial steam turbine. Firstly, the form of district hot water boiler room heating system and the driving load of industrial steam turbine are analyzed in the district steam boiler room and district steam hot water boiler room. Exhaust steam is used for steam and water heat transfer to realize energy cascade utilization and "heat and power cogeneration" system form, and draw the schematic diagram of various forms of district boiler room heating system. Secondly, the allocation of boiler capacity and number, boiler and drag load, and industrial steam turbine and heat exchanger for driving load are studied. The configuration scheme of boiler and drag load, industrial steam turbine and steam-water heat exchanger in the boiler room in cold and cold regions is obtained, and the regional hot water boiler room of 4 29MW~99MW in cold area and 3 46MW~99MW in cold area is obtained. The area steam boiler room and the area steam hot water boiler room carries on the equipment. Thirdly, the operation regulation and energy consumption of the boiler and its circulating pump, boiler drum, induced fan and feed water pump in the district boiler room heating system in cold and cold areas are studied. The operation adjustment formula and energy consumption formula of boiler and its drag load in different forms of district boiler room heating system in cold and cold regions are obtained. Examples of typical cities in cold and cold regions are analyzed. The operation regulation process and energy consumption of typical urban boiler and drag load are obtained. Finally, an economic model of the annual cost per unit heating area of the district boiler room heating system is established, and the economy and energy saving of the regional steam boiler room and the regional steam hot water boiler room are analyzed. Based on the case study of a heating system with an area of 2 million m ~ 2 ~ 7 million m ~ 2 in cold and cold regions, it is concluded that the economy of the district steam hot water boiler room heating system is better than that of the regional steam boiler room heating system. The steam boiler room heating system is superior to the hot water boiler room heating system, the industrial steam turbine is used instead of the motor to drive the load, the power can be saved by 1.39kwhr / m2n 1.88kwhr / m2 in the cold area, and 0.96kwhr / m2c1.36kwhp / m2 by the cold region, considering the extra coal consumption of the industrial steam turbine drag load, The 0.06kg standard coal / m ~ 2a ~ (-1) standard coal / m ~ (2a) standard coal /
