沼气发动机主要有两种利用沼气具体形式，一种是驱动发电机发电，向厂内供电或送入市电网，供电器用电；另一种是直接驱动鼓风机，节省电能。而沼气发动机本身的热量可向污泥厌氧中温消化供余热。下面沼气发电机组厂家为您讲说。

The biogas engine mainly uses biogas in two specific forms: one is to drive the generator to generate electricity, supply power to the plant or the municipal power grid, and the power supply device uses electricity; The other is to directly drive the blower to save electric energy. The heat of biogas engine can provide waste heat for anaerobic mesophilic digestion of sludge. Next, the manufacturer of biogas generator sets will tell you.

①这两种利用沼气的形式各有优势。前一种（发电机）的优点较后一种（直接驱动鼓风机）运行灵活，可随时发电供厂内电器使用。

① The two forms of biogas utilization have their own advantages. The former (generator) has the advantages of flexible operation compared with the latter (directly driven blower), and can generate power at any time for the use of electrical appliances in the plant.

②两种形式的机械效率不同。沼气发动机的机械效率一般在20%～30%之间，当采用沼气发电形式时，沼气中的能量只有15%～23%转化成了有效的机械能。当采用发动机直接驱动鼓风机时，其有效机械能为沼气能量的20%～30%，相对沼气发电机效率要高一些。

② The mechanical efficiency of the two forms is different. The mechanical efficiency of biogas engine is generally 20%~30%. When biogas power generation is adopted, only 15%~23% of the energy in biogas is converted into effective mechanical energy. When the engine is used to directly drive the blower, its effective mechanical energy is 20%~30% of the biogas energy, which is higher than the biogas generator efficiency.

③对于沼气发动机来说，沼气中的能量除20%～30%转化成了机械能外，还有约30%以热量的形式转化到冷却水中，30%以热量的形式随烟气带走，还剩10%为机体本身热损耗和震动损耗，也就是说沼气能量中约60%转化成了热量。

③ For biogas engines, in addition to 20%~30% of the energy in biogas is converted into mechanical energy, about 30% of the energy in biogas is converted into cooling water in the form of heat, 30% is taken away with flue gas in the form of heat, and 10% is the heat loss and vibration loss of the body itself, that is, about 60% of the energy in biogas is converted into heat.

④在实际生产中，通过有效的热交换，30%的沼气能量以90%的转化率转换到冷却水中。另外30%的沼气能量以65%的转化率被回收用于加热污泥，两项共计利用率达47%～56%，即沼气中能量的47%～56%被回收用于污泥加热。综合沼气发动机所耗能量，沼气能量的实际总利用率为67%～86%。

④ In actual production, 30% of biogas energy is converted to cooling water at 90% conversion rate through effective heat exchange. In addition, 30% of the biogas energy is recycled for heating sludge with a conversion rate of 65%. The total utilization rate of the two items is 47%~56%, that is, 47%~56% of the energy in the biogas is recycled for heating sludge. Considering the energy consumption of biogas engine, the actual total utilization rate of biogas energy is 67%~86%.

此外构成沼气发电系统的主要设备有沼气发电机组、发电机和热回收装置。沼气经脱硫器由贮气罐供给燃气发电机组，从而驱动与沼气内燃机相连接的发电机而产生电力。沼气发电机组排出的冷却水和废气中的热量通过热回收装置进行回收后，作为沼气发生器的加温热源。关注我们//www.gz-yanye.com带你了解更多内容！

In addition, the main equipment constituting the biogas power generation system includes biogas generator set, generator and heat recovery device. The biogas is supplied to the gas generator set by the gas storage tank through the desulfurizer to drive the generator connected to the biogas internal combustion engine to generate electricity. The heat in the cooling water and waste gas discharged from the biogas generator set is recycled by the heat recovery device and used as the heating source of the biogas generator.
