Policy support: Equipment subsidies in some regions, no subsidies. Fire power supply is not a fire source and can be used. Fire power supply equipment costs are high and low. Discussion on the application of triple gas supply system in internal combustion engines

　　冷热电三联供：主要用于燃气发电机组高温钢瓶水和高温烟气的余热回收，并通过配套设备将这部分余热转化为空调冷水、热水、饱和蒸汽等其他形式的热能。满足热负荷要求。该应用主要适用于冷热两用用户，这些用户主要分布在城市。

　　Combined cooling, heating and power supply: mainly used for the recovery of waste heat from high-temperature steel cylinder water and high-temperature flue gas in gas generator sets, and through supporting equipment, this waste heat is converted into other forms of heat energy such as air conditioning cold water, hot water, saturated steam, etc. Meet the heat load requirements. This application is mainly suitable for users who can use both hot and cold, and these users are mainly distributed in cities.

　　燃气内燃机的应用

　　Application of Gas Internal Combustion Engines

　　根据燃气内燃发电机组和市政供电的运行方式，可分为：孤岛式、电网不上网、不上网售电。

　　According to the operation mode of gas-fired internal combustion generator sets and municipal power supply, they can be divided into island type, off grid, and off grid electricity sales.

　　孤岛模型：发电机与市政电力分开运行，两者之间没有连接。电网连接，但没有互联网接入：发电机和市电共用负荷，二者通过并联柜并网，但总负荷大于机组输出功率，机组不向电网供电。在线售电：发电机组和市电共用负荷。两者都通过并联柜连接到电网。系统负荷小于发电机组的输出功率。发电机组多余的电力输出可以送回电网销售。系统效率及其影响因素独立效率系统效率独立效率通常是指电效率。系统效率是指系统的总能量利用率，系统的年利用率。气体质量每台设备独立效率环境温度合理的系统规划环境海拔多层次能源利用负载条件设备利用率工作一致性系统年运行时间维护条件维护间隔通风条件设备稳定性

　　Island model: The generator and municipal power operate separately without any connection between them. Grid connection, but no Internet access: the generator and the mains share loads, and they are connected to the grid through parallel cabinets, but the total load is greater than the output power of the unit, and the unit does not supply power to the grid. Online electricity sales: Generator sets and mains electricity share the same load. Both are connected to the power grid through parallel cabinets. The system load is less than the output power of the generator set. The excess power output of the generator set can be sent back to the grid for sale. System efficiency and its influencing factors - Independent efficiency - System efficiency - Independent efficiency usually refers to electrical efficiency. System efficiency refers to the total energy utilization rate and annual utilization rate of the system. Gas quality, independent efficiency of each equipment, reasonable environmental temperature, system planning, altitude, multi-level energy utilization, load conditions, equipment utilization efficiency, work consistency, annual operating time, maintenance conditions, maintenance intervals, ventilation conditions, equipment stability

　　影响系统效率的主要因素

　　The main factors affecting system efficiency

　　一。设备选型合理。确定“电热/电热”模式，以确保可以消耗所有能量输出。2.设备的正确匹配。系统各部分匹配，避免“大配小/大配小”的情况。三。设备年利用率确保系统处于正常状态，以避免空闲或低功耗操作。四。设备维护周期及费用。维护周期长，检修周期长，避免系统因维护而停机。维护费用也会影响系统的使用。5个。设备的稳定性。核心设备能够长期稳定运行，是系统运营收入的基本条件。6.售后服务反应快。快速完善的售后服务提醒是系统长期有效运行的重要保证。

　　One. Reasonable equipment selection. Determine the "electric heating/electric heating" mode to ensure that all energy output can be consumed. 2. Correct matching of equipment. Match various parts of the system to avoid the situation of "large matching small/large matching small". Three. The annual utilization rate of equipment ensures that the system is in a normal state to avoid idle or low-power operations. Four. Equipment maintenance cycle and cost. Long maintenance cycle, long overhaul cycle, to avoid system shutdown due to maintenance. Maintenance costs can also affect the use of the system. 5 of them. The stability of the equipment. The long-term stable operation of core equipment is a basic condition for system operating income. 6. Quick after-sales service response. Quick and comprehensive after-sales service reminders are an important guarantee for the long-term effective operation of the system.
