  传统的80kw燃气发电机组燃气涡轮发电机是大型发电设施的典型例子,它可以提供1到几兆瓦的电力,满足几乎所有建筑的需求,包括办公楼、医院、学校和商店。汽轮发电机排出的废气是吸收式制冷机的理想热源,用于制冷、供热和提供卫生热水。与燃煤电厂的废气相比,废气中的杂质和硫含量非常低,其次是显著的氧含量,可以达到15%以上,可以作为直燃机的燃烧空气进行二次燃烧。燃气轮机常用于调节夏季的用电高峰。但由于夏季高温,燃气轮机出力严重不足,效率降低。
  The traditional 80 kW gas turbine generator is a typical example of large-scale power generation facilities. It can provide 1 to a few megawatts of power to meet the needs of almost all buildings, including office buildings, hospitals, schools and shops. The exhaust gas from the turbogenerator is the ideal heat source of the absorption chiller, which is used for cooling, heating and providing sanitary hot water. Compared with the waste gas of coal-fired power plant, the content of impurities and sulfur in the waste gas is very low, followed by the significant oxygen content, which can reach more than 15%, and can be used as the combustion air of direct fired machine for secondary combustion. Gas turbines are often used to regulate the peak power consumption in summer. However, due to the high temperature in summer, the output of gas turbine is seriously insufficient and the efficiency is reduced.

  因此,溴化锂制冷机通过利用汽轮发电机的排气制冷来冷却汽轮发电机的进气,可以大大提高汽轮发电机的出力和效率。它已被证明是一种非常有效的节能方式。汽轮发电机通常由涡轮、齿轮箱、发电机、进气增压器和排气系统组成。根据水轮发电机组的不同流量,将其分为联合循环、简单循环和前循环。蒸汽由余热锅炉从燃气轮机的废气中产生,驱动汽轮机发电或直接提供蒸汽的联合循环,是新电厂普遍采用的一种工艺。溴化锂吸收式制冷机通过回收燃气轮机或废热锅炉的废气余热或废热锅炉的中低压蒸汽进行制冷,实现冷、热、电三合一循环。
  Therefore, the output and efficiency of the turbogenerator can be greatly improved by using the exhaust refrigeration of the turbogenerator to cool the intake air of the turbogenerator. It has been proved to be a very effective way to save energy. Turbogenerator usually consists of turbine, gearbox, generator, intake supercharger and exhaust system. According to the different flow rate of the hydrogenerator, it can be divided into combined cycle, simple cycle and pre cycle. Steam is produced by waste heat boiler from the waste gas of gas turbine, which drives steam turbine to generate electricity or provides steam directly. It is a common process used in new power plant. Lithium bromide absorption chiller can realize the cold, heat and electricity three in one cycle by recycling the waste heat of gas turbine or waste heat boiler or the medium and low pressure steam of waste heat boiler.
  一、根据甲烷产量
  1、 Based on methane production
  如果沼气产量大,而且沼气发电机可以把电送到互联网上,那么沼气发电机就可以根据沼气每小时产生的电量来计算发电。例如,每天的沼气产量是12000立方米,也就是每小时500立方米。CH4含量按50%计算,发电量1000 KWH / h。因此,可以选择两台500KW的沼气发生器。
  If the biogas production is large, and the biogas generator can send the electricity to the Internet, then the biogas generator can calculate the power generation according to the hourly electricity generated by the biogas. For example, the biogas production per day is 12000 cubic meters, that is, 500 cubic meters per hour. CH4 content is calculated as 50%, and the generating capacity is 1000 kwh / h. Therefore, two 500kW biogas generators can be selected.
  二、根据用电负荷
  2、 According to the power load
  该模型适用于小型沼气生产单位,如大中型养殖场、沼气发电机按负荷较集中时段计算大负荷。例如:沼气产量每天1000立方,形成一套完整的300立方米的天然气,单位负荷波动40千瓦到150千瓦,你可以选择8 - 10小时集中负荷的使用浓度,沼气100立方米/小时,可以选择180 - 250千瓦的沼气发电模式(因为沼气发电模式在单台机器工作,冲击载荷较大,一些更大的权力)。
  The model is suitable for small biogas production units, such as large and medium-sized farms and biogas generators, to calculate the large load according to the period when the load is relatively concentrated. For example: the biogas output is 1000 cubic meters per day, forming a complete set of 300 cubic meters of natural gas. The unit load fluctuates from 40 kilowatts to 150 kilowatts. You can choose the concentration of 8-10 hours of concentrated load, biogas 100 cubic meters per hour, and biogas power generation mode of 180-250 kilowatts (because the biogas power generation mode works in a single machine, with large impact load, and some greater power).
  三、根据沼气的用量和用电负荷综合考虑
  3、 Comprehensive consideration of biogas consumption and power load这种情况适合沼气量较大,使用单位不能发电上网,自己完全可以消耗发电能力。
  This situation is suitable for a large amount of biogas, the user can not generate electricity on the Internet, and can completely consume the power generation capacity.
  使用单位可单独选择一套布线沼气发生器作为单独的电源。沼气发生器应具有自燃和电网切换功能,并能在沼气发生器的维护过程中自动切换,避免生产延误。
  The user can select a set of wiring biogas generator as a separate power supply. The biogas generator shall have the function of spontaneous combustion and power grid switching, and be able to switch automatically in the maintenance process of the biogas generator to avoid production delay.
