Description
技术领域technical field
本实用新型属于火电厂节能降耗领域，涉及一种邻机凝结水互联系统。The utility model belongs to the field of energy saving and consumption reduction in thermal power plants, and relates to a condensate water interconnection system of adjacent machines.
背景技术Background technique
近几年全国发电装机容量快速增长，电力供需形势总体富裕、绝大地区装机过剩，火电机组年利用小时数呈逐年下降趋势。国内经济增速总体呈现稳中趋缓态势，预测未来数年内全社会用电需求仍处于低迷态势。新能源发电如光伏光热、风电、水电等迅猛发展以及政策引导，火电机组势必将面临深度调峰、长周期停运等问题。从这一角度来讲，火电机组冷态启动频率及总次数将大大增加。在全厂各个领域、各个环节发掘节能潜力并付诸实施，是未来节能工作必须坚持的基本原则。In recent years, the installed capacity of power generation in the country has grown rapidly, the overall power supply and demand situation is affluent, and the installed capacity in most regions is oversupplied. The annual utilization hours of thermal power units are showing a downward trend year by year. The domestic economic growth rate is generally stable and slowing down, and it is predicted that the demand for electricity in the whole society will remain in a downturn in the next few years. With the rapid development of new energy power generation such as photovoltaic solar thermal, wind power, and hydropower and policy guidance, thermal power units are bound to face problems such as deep peak regulation and long-term outages. From this point of view, the cold start frequency and total number of thermal power units will be greatly increased. Discovering energy-saving potentials in all fields and links of the whole plant and putting them into practice is the basic principle that must be adhered to in future energy-saving work.
对停运时间较长(一般超过150小时以上)的机组，应进行锅炉清洗。锅炉清洗主要目的是清洗沉积在受热面上的杂质、盐分和腐蚀生成的氧化铁等。机组启动初期，首先将对低压段管路进行清洗，包括冷凝给水管路及低压加热管道部分的清洗；然后进行除氧给水及高压加热管道部分的清洗；待这段水质清洗满足要求后可进行锅炉的清洗工作。一般来讲，亚临界机组在完成冷态冲洗(水源为凝结水补水在除氧器经邻机辅汽加热的高温凝结水)后即可进行锅炉上水；超临界机组在完成冷态冲洗后锅炉点火转为热态冲洗，进入锅炉的水源仍为凝补水在除氧器经邻机辅汽加热的高温凝结水。可见，邻机辅汽(冷再或四段抽汽)加热始终贯穿于整个机组启动过程中，持续时间自锅炉上水到启动机组带基本负荷，持续时间长且消耗量较大。For units that have been shut down for a long time (generally more than 150 hours), boiler cleaning should be carried out. The main purpose of boiler cleaning is to clean the impurities deposited on the heating surface, salt and iron oxide formed by corrosion. At the initial stage of unit start-up, the low-pressure pipeline will be cleaned first, including the cleaning of the condensate feed water pipeline and the low-pressure heating pipeline; then the deoxygenated water supply and the high-pressure heating pipeline will be cleaned; after the water quality cleaning of this section meets the requirements, it can be carried out Boiler cleaning work. Generally speaking, after the subcritical unit completes the cold flushing (the water source is condensed water replenishment, the high-temperature condensed water heated by the auxiliary steam of the adjacent machine in the deaerator), the boiler can be filled with water; after the supercritical unit completes the cold flushing Boiler ignition turns to hot state flushing, and the water source entering the boiler is still high-temperature condensate water heated by the auxiliary steam of the adjacent machine in the deaerator. It can be seen that the auxiliary steam (cold reheating or four-stage steam extraction) heating of the adjacent machine runs through the whole unit start-up process, and the duration is long and consumes a lot from boiler water supply to start-up unit with basic load.
