3.1 use the waste heat of circulating cooling water of gas generator set for heating of surrounding residents in winter

在附近居民及厂房供暖暖系统加压泵的管道上接上高温循环管线，让高温循环水(吸热后)直接进入并入用户的取暖系统，如需要降低供暖温度可用调节高温循环水上塔门来调整，这样，循环冷却水余热回收利用到供暖系统的小技改，节约了能源，创造了经济效益，同时还改善了周围的环境，推进节约型企业建设，保护生态环境和资源综合利用。

Connect the high-temperature circulating pipeline to the pipeline of the booster pump of the heating system of nearby residents and plants, so that the high-temperature circulating water (after heat absorption) can directly enter the heating system incorporated into the user. If it is necessary to reduce the heating temperature, it can be adjusted by adjusting the high-temperature circulating water tower door. In this way, the waste heat of the circulating cooling water can be recycled into the small technical transformation of the heating system, saving energy and creating economic benefits, At the same time, it has also improved the surrounding environment, promoted the construction of energy-saving enterprises, protected the ecological environment and comprehensive utilization of resources.

3.2 利用瓦斯发电机组循环冷却水的余热用于附近农户提供农业大棚加热系统

3.2 use the waste heat of circulating cooling water of gas generator set to provide agricultural greenhouse heating system for nearby farmers

分别接入高低冷却水池管路至农业加热大棚骨架母管，通过加压泵接入农业大棚骨架母管循环。可调节高低温水池入口阀门大小，来调节加热骨架母管温度。通过在大棚骨架母管的循环水热量辐射，使得冬季农户大棚保持适当的温度，用于冬季里的农业蔬菜种植。

Connect the high-low cooling water tank pipeline to the framework main pipe of agricultural heating greenhouse respectively, and connect it to the framework main pipe of agricultural greenhouse through booster pump for circulation. The size of the inlet valve of the high and low temperature water tank can be adjusted to adjust the temperature of the main pipe of the heating skeleton. Through the heat radiation of circulating water in the main pipe of the greenhouse skeleton, farmers' greenhouse can maintain an appropriate temperature in winter for agricultural vegetable planting in winter.

3.3 利用瓦斯发电机组排放的烟气余热用于发电站及周边建筑住户的冬季取暖

3.3 the waste heat of flue gas discharged by gas generator set is used for winter heating of power station and surrounding buildings

瓦斯发电机组烟气余热的回收利用，实际就是在发电机组排气管末端安装一烟气余热锅炉，通过热网循环泵把供暖水通过烟气余热锅炉，提高至冬季用户取暖的适合温度。

The recovery and utilization of flue gas waste heat of gas generator set is actually to install a flue gas waste heat boiler at the end of the exhaust pipe of the generator set, and raise the heating water through the flue gas waste heat boiler through the heat network circulating pump to the suitable temperature for heating users in winter.
