沼气发电机组通过混合器与空气混合，经增压、中冷、自动调节阀后进入燃烧室，可适应低压燃烧。整机自动化程度高，机组经济性、可靠性、安全性、适应性等方针抵达高水平。那么沼气发电机组的选择应先考虑的要素是怎样的呢？

The biogas generator unit is mixed with the air through the mixer, and enters the combustion chamber through the pressurization, intercooling and automatic control valve, which can adapt to low-pressure combustion. The whole machine has a high degree of automation, and the economy, reliability, safety and adaptability of the unit have reached a high level. What are the factors that should be considered first in the selection of biogas generating units?

沼气发电是一种运用生物质动力的可再生新动力运用技能与一台相同功率的小型沼气发电机组设备相比，小型风力发电机组的设备价格是其价格的3~4倍；一套太阳能发电设备的价格是其价格的22倍以上小型沼气发电只需要缔造沼气池，其建池本钱略相当于小型沼气发电设备的本钱。

Biogas power generation is a renewable new power application skill using biomass power. Compared with a small biogas generator set with the same power, the equipment price of small wind turbine is 3-4 times of its price; The price of a set of solar power generation equipment is more than 22 times of its price. Small biogas power generation only needs to create a biogas digester, and its construction cost is slightly equivalent to that of small biogas power generation equipment.

现在村庄区域已经有不少户用沼气池，而且均由国家财政补贴支撑缔造而沼气池的材料首要是人畜粪便农作物秸秆等废料，本钱底子为零除此之外，沼气发电相对于风能和太阳能还具有以下一些长处：

At present, there are many household biogas digesters in the village area, all of which are supported by the state financial subsidies. The materials of biogas digesters are mainly human and animal excrement, crop straw and other wastes, and the cost base is zero. In addition, biogas power generation has the following advantages over wind energy and solar energy:

1.运用便当，不受气候和环境的限制。

1. The use of Bento is not limited by climate and environment.

2.材料来自生活生产废料，一同协助处理了废料形成的环境污染问题。

2. The materials are from domestic and production wastes, which together helped to deal with the environmental pollution caused by the wastes.

3.沼气池产生的沼渣沼液是优秀的农家肥，完成了农家废物的循环运用

3. The biogas residue and biogas slurry produced by the biogas digester are excellent farm manure, which completes the recycling of farm wastes

4.小型沼气发电设备细巧，搬运便当，在沼气输气管可达当地可就近为小型电动农用机具供电。

4. The small-scale biogas power generation equipment is delicate and easy to carry. The small-scale electric agricultural machines and tools can be supplied with power near the biogas transmission pipeline.

2.沼气发电机组的选择应考虑的首要要素

2. The primary factors to be considered in the selection of biogas generating units

沼气发电机组的选择应考虑的要素首要有机械与电气功用、机组的用途、负荷的容量与改动规划、自动化功用等。

The main factors to be considered in the selection of biogas generating units are mechanical and electrical functions, unit uses, load capacity and change planning, automation functions, etc.

(1)机组的用途。因为沼气发电机组可用于常用、备用和应急等3种情况。因而不同用途对柴油发电机组 的要求就有所区别。

(1) Purpose of the unit. Because the biogas generator set can be used in three situations, i.e. common use, standby and emergency. Therefore, the requirements of diesel generator set for different purposes are different.

(2)负荷容量。应根据不同用途选择负荷容量和负荷的改动规划，断定沼气发电机的单机容量和备用沼气发电机组容量。

(2) Load capacity. The load capacity and load change planning shall be selected according to different purposes, and the single unit capacity and standby biogas generator unit capacity shall be determined.

(3)机组的运用环境条件(首要指海拔高度和气候条件)

(3) Operating environmental conditions of the unit (mainly referring to altitude and climate conditions)

(4)沼气发电机组的选择

(4) Selection of biogas generator set

(5)发电机与励磁方式的选择

(5) Selection of generator and excitation mode
