1、首先对沼气发电机房的位置作出规范，一般来说放在第1层或者是地下一层，同时要达到耐火的极限，不能够低于两个小时的隔墙。而且楼板与其他部位要隔开，要做好防泄漏的措施。

　　Firstly, the location of the biogas generator room should be standardized. Generally, it should be placed on the first floor or the basement, and it must meet the fire resistance limit, with a partition wall that cannot be breached for less than two hours. Moreover, the floor slab should be separated from other parts, and measures to prevent leakage should be taken.

　　2、沼气发电机房要具备消防的设施，这里面就有水枪、消防栓，另外在机房内部还需要配置干粉灭火器以及气体的灭火器，同时要有显著的标语提醒人们。

　　2. The biogas generator room must be equipped with fire-fighting facilities, including water guns and fire hydrants. Additionally, dry powder fire extinguishers and gas fire extinguishers should be installed inside the room, and prominent signs should be provided to remind people.

　　3、这里面是不能够有明火的，而且在机房内还需要设置干燥的沙池，起到了消防的目的。要有照明的系统，还有独立的抽风系统以及火灾报警的装置等等。

　　3. No open flames are allowed here, and a dry sandpit needs to be set up in the machine room for fire prevention purposes. There should be a lighting system, an independent ventilation system, a fire alarm device, and so on.

　　沼气发电机机房的设置要求和选址注意事项

　　1、通风要求

　　沼气发电机房的通风问题是机房设计中要特别注意解决的问题，特别是发电机组机房位于地下室时更要处理好，否则会直接影响发电机组的运行。机组的排风一般应设热风管道，不宜让柴油机散热器把热量散在机房内，再由排风机抽出。机房内要有足够的新风补充。柴油机在运行时，机房的换气量应等于或大于柴油机燃烧所需新风量与维持机房室温所需新风量之和。进风口与出风口宜分别布置在机组的两端，以免形成气流短路，影响散热效果。

　　Requirements for the setup and site selection of biogas generator rooms1. Ventilation requirementsThe ventilation issue of the biogas generator room is a particularly important issue to address in the design of the room, especially when the generator set room is located in the basement. Otherwise, it will directly affect the operation of the generator set. The exhaust air of the unit should generally be equipped with a hot air duct, so as not to allow the diesel engine radiator to dissipate heat inside the room and then be extracted by the exhaust fan. There should be sufficient fresh air supply in the room. When the diesel engine is running, the ventilation rate of the room should be equal to or greater than the sum of the fresh air volume required for diesel engine combustion and the fresh air volume required to maintain the room temperature. The air inlet and outlet should be arranged at both ends of the unit to avoid forming an airflow shortcut, which will affect the heat dissipation effect.

　　2、防尘要求

　　发电机组机房防尘不好，也会对设备产生危害，在保证机房通风的情况下，同时考虑到机房的防尘作用，加装进风排风百叶，保证机房的风质和风量。

　　2. Dust Prevention Requirements

　　Poor dust prevention in the generator set room can also pose a hazard to the equipment. While ensuring proper ventilation in the room, it is also necessary to consider its dust prevention function by installing air intake and exhaust louvers to ensure the quality and volume of air in the room.

　　3、排烟系统

　　设置排烟系统的作用是将气缸里的废气排放到室外。排烟系统应尽量减少背压，因为，废气阻力的增加将会导致柴油机出力的下降及温升的增加。排烟管敷设方式常用的是水平架空敷设和地沟内敷设。在地下室常用的是水平架空敷设。

　　3. Exhaust SystemThe purpose of setting up an exhaust system is to discharge the exhaust gas from the cylinder to the outside. The exhaust system should minimize back pressure, as an increase in exhaust gas resistance will lead to a decrease in diesel engine output and an increase in temperature rise. Common methods of laying exhaust pipes include horizontal overhead laying and laying in trenches. Horizontal overhead laying is commonly used in basements.

　　4、基础要求

　　基础主要用于支撑发电机组及底座的全部重量，底座位于基础上，机组安装在底座上，底座上一般都采取减震措施。在高层建筑中一般采用高速发电机组，当机组安装在楼板上时，不采用重混凝土基础，以免基础过重而增加楼板荷重。当机组位于建筑物底层时，应按机组要求设置混凝土基础。

　　4. Basic RequirementsThe foundation is primarily used to support the entire weight of the generator set and its base. The base sits on the foundation, and the unit is installed on top of it. Shock absorption measures are typically taken on the base. In high-rise buildings, high-speed generator sets are commonly used. When the unit is installed on the floor, a heavy concrete foundation is not recommended to avoid increasing the load on the floor due to an overly heavy foundation. When the unit is located on the ground floor of the building, a concrete foundation should be set up according to the requirements of the unit.

　　5、机房接地

　　发电机房一般使用三种接地。工作接地，发电机组中性点接地。保护接地，电气设备正常不带电的金属外壳接地。防静电接地，燃油系统的设备及管道接地。各种接地可与高层建筑的其他接地共用接地装置，即采用联合接地方式。

　　5. Machine room grounding: Three types of grounding are generally used in generator rooms. Working grounding, which refers to the grounding of the neutral point of the generator set. Protective grounding, which refers to the grounding of metal enclosures of electrical equipment that are normally not charged. Anti-static grounding, which refers to the grounding of equipment and pipelines in the fuel system. Various groundings can share grounding devices with other groundings in high-rise buildings, i.e., adopting a joint grounding method.

　　6、首层较佳

　　一般发电机组的机房都会设置在地下室，但如果有条件的话机房尽量设在首层。柴油发电机房的选址考虑到发电机组的进风、排风、排烟等情况，首层是理想选择，但困难点在于首层通常用于对外营业，且造价昂贵。

　　6. Preferably on the ground floorGenerally, the engine room of a generator set is located in the basement, but if conditions permit, it should be situated on the ground floor as much as possible. When selecting the location for a diesel generator room, factors such as air intake, exhaust, and smoke evacuation of the generator set should be considered. The ground floor is an ideal choice, but the difficulty lies in the fact that it is usually used for external business operations and is expensive to construct.
