在我國，沼氣發電技術已趨於成熟。科學合理地開發利用沼氣，不僅能創造可觀的經濟效益，還能保護生態環境，促進可再生能源的開發利用。下麵來講講沼氣好色先生在线观看排出的冷卻水和廢氣中的熱量回收問題的相關內容吧。

In China, biogas power generation technology has become mature. Scientific and rational development and utilization of biogas can not only create considerable economic benefits, but also protect the ecological environment and promote the development and utilization of renewable energy. Let's talk about the heat recovery in the cooling water and exhaust gas discharged from the biogas generator set.

沼氣好色先生在线观看排出的冷卻水和廢氣中的熱量通過熱回收裝置進行回收後，沼氣好色先生在线观看作為沼氣發生器的加溫熱源。從廢水處理廠出來的汙泥進入一次消化槽和二次消化槽，在消化槽中產生的沼氣首先經脫硫器進入球形貯氣罐，然後由此輸送入沼氣發電裝置中。

After the heat in the cooling water and exhaust gas discharged by the biogas generator is recovered by the heat recovery device, the biogas generator is used as the heating source of the biogas generator. The sludge from the wastewater treatment plant enters the primary digestion tank and the secondary digestion tank. The biogas generated in the digestion tank first enters the spherical gas storage tank through the desulfurizer, and then is transmitted to the biogas power generation device.

作為好色先生在线观看燃料的沼氣中甲烷的含量必須高於50%，不必要進行二氧化碳的脫除，因為少量二氧化碳對好色先生在线观看有利，使其工作平穩，減少廢氣中有毒物的含量。從發電裝置出來的廢沼氣進入熱交換器中，大型沼氣好色先生在线观看，將熱量釋放出來，用來加熱進行厭氧發酵的汙泥，沼氣好色先生在线观看，從而提高沼氣的發生率。

The methane content in the biogas used as the fuel of the generator set must be higher than 50%. It is unnecessary to remove carbon dioxide, because a small amount of carbon dioxide is beneficial to the generator set, making it work smoothly and reducing the content of toxic substances in the exhaust gas. The waste biogas from the power generation unit enters the heat exchanger, and the large biogas generator set releases the heat to heat the sludge for anaerobic fermentation, so as to improve the occurrence rate of biogas.

此外沼氣發電係統能積極、有效地利用沼氣，可以將沼氣中約30%的能量變為電力，40%的能量變為熱能。沼氣發動機在完全滿足人們對環保嚴格要求的同時，利用四衝程、高壓點火、渦輪增壓、中冷器、稀釋燃燒等技術，通過沼氣在汽缸內燃燒做功，將沼氣的化學能轉換成機械能。

In addition, the biogas power generation system can actively and effectively use biogas, which can turn about 30% of the energy in biogas into electricity and 40% into heat energy. While fully meeting people's strict requirements for environmental protection, the biogas engine uses four stroke, high-pressure ignition, turbocharging, intercooler, dilution combustion and other technologies to convert the chemical energy of biogas into mechanical energy by burning the biogas in the cylinder.

於此同時，利用熱回收技術可將燃氣內燃機中潤滑油、中冷器、缸套水和尾氣排放中的熱量充分回收利用而組成熱動機組。一般從發動機熱回收係統中吸收的熱量以90℃的熱水形式供給熱交換使用。

At the same time, the heat recovery technology can be used to fully recover the heat in the lubricating oil, intercooler, cylinder liner water and exhaust emissions of gas-fired internal combustion engines to form a thermal power unit. Generally, the heat absorbed from the engine heat recovery system is supplied to the heat exchange center in the form of 90 ℃ hot water.

內燃機正常回水溫度為70℃。在汙水處理廠中可利用這一熱量給消化池進行加熱。燃氣內燃機機械效率通常達40%，熱效率可達50%，總效率高達90%。通常在O2為5%的情況下燃燒後排放的NOx≤0毫克/米3，完全滿足環保的要求。因此，沼氣好色先生在线观看餘熱利用大有使用價值。

The normal return water temperature of internal combustion engine is 70 ℃. This heat can be used to heat the digestion tank in the sewage treatment plant. The mechanical efficiency of gas-fired internal combustion engine is usually 40%, the thermal efficiency is 50%, and the total efficiency is as high as 90%. Generally, when O2 is 5%, NOx emitted after combustion is ≤ 0 mg / m3, which fully meets the requirements of environmental protection. Therefore, the waste heat utilization of biogas generating units is of great value.
