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

在附近居民及廠(chǎng)房供暖暖系統加壓泵的管道上接上高溫循環(huán)管線(xiàn)，讓高溫循環(huán)水(吸熱后)直接進(jìn)入并入用戶(hù)的取暖系統，如需要降低供暖溫度可用調節高溫循環(huán)水上塔門(mén)來(lái)調整，這樣，循環(huán)冷卻水余熱回收利用到供暖系統的小技改，節約了能源，創(chuàng )造了經(jīng)濟效益，同時(shí)還改善了周?chē)沫h(huán)境，推進(jìn)節約型企業(yè)建設，保護生態(tài)環(huán)境和資源綜合利用。

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 利用瓦斯發(fā)電機組循環(huán)冷卻水的余熱用于附近農戶(hù)提供農業(yè)大棚加熱系統

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

分別接入高低冷卻水池管路至農業(yè)加熱大棚骨架母管，通過(guò)加壓泵接入農業(yè)大棚骨架母管循環(huán)?？烧{節高低溫水池入口閥門(mén)大小，來(lái)調節加熱骨架母管溫度。通過(guò)在大棚骨架母管的循環(huán)水熱量輻射，使得冬季農戶(hù)大棚保持適當的溫度，用于冬季里的農業(yè)蔬菜種植。

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 利用瓦斯發(fā)電機組排放的煙氣余熱用于發(fā)電站及周邊建筑住戶(hù)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

瓦斯發(fā)電機組煙氣余熱的回收利用，實(shí)際就是在發(fā)電機組排氣管末端安裝一煙氣余熱鍋爐，通過(guò)熱網(wǎng)循環(huán)泵把供暖水通過(guò)煙氣余熱鍋爐，提高至冬季用戶(hù)取暖的適合溫度。

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.
