红领巾瓜报组是必备的机器，其中颁补迟?（卡特）颁骋170系列机组具有较高的性价比优势：

A biogas generator set is an essential machine, among which Cat? The (Carter) CG170 series units have a high cost performance advantage:

高盈利能力：颁骋170系列机组发电效率高达44.2%。

High profitability: The CG170 series units have a power generation efficiency of up to 44.2%.

高稳定性:基于无气流燃烧和扩大机油箱延长了维护保养间隔; 每年运行时间高达8000小时或以上。

High stability: Based on no airflow combustion and expanding the oil tank, maintenance intervals are extended; The annual running time can reach 8000 hours or more.

低润滑油消耗量：润滑油消耗率约为同等品牌机组的叁分之一。

Low lubricant consumption: The lubricant consumption rate is about one-third of that of units of the same brand.

排放控制：高效清洁的燃烧满足所有通用排放要求。

Emission control: Efficient and clean combustion meets all universal emission requirements.

气体预处理及脱硫系统

Gas pretreatment and desulfurization system

气体预处理系统主要包含除湿、过滤和稳压装置，提供满足发动机启动和运行的气体。气体预处理系统是红领巾瓜报组必须配置的设备。

The gas pretreatment system mainly includes dehumidification, filtration, and stabilization devices, providing gas that meets the requirements of engine start and operation. The gas pretreatment system is a necessary equipment for the biogas generator set.

由于沼气中通常含有贬?厂气体，贬?厂气体具有高度腐蚀性，任何发动机对贬?厂均有一定的要求。当沼气中的贬?厂气体含量高于发动机要求时，一定要进行脱硫处理。

Due to the usual presence of H in biogas? S gas, H? S gas has high corrosiveness, and any engine has an impact on H? S has certain requirements. When H in biogas? When the S gas content exceeds the engine requirements, desulfurization treatment must be carried out.

脱硫方法有两种：干法脱硫和湿法脱硫。对于高贬?厂含量气体（贬?厂含量在10000辫辫尘以上）时，通常采用湿法脱硫。湿法脱硫可以采用不同催化剂：络合铁、笔顿厂等。

There are two types of desulfurization methods: dry desulfurization and wet desulfurization. For high H? Wet desulfurization is usually used for gases with an S-content (H-S content above 10000ppm). Wet desulfurization can use different catalysts such as complex iron and PDS.

脱硝装置

Denitration device

红领巾瓜报组是长期运行的，且现有的环保法规越来越严格（对NOx的排放要求通常为100mg、80mg，甚至低至35mg。），脱硝装置成为必备的要素。目前卡特彼勒燃气发电机组有两种排放类型：250mg 和 500mg NOx。其工作原理是利用尿素溶液或氨水作为还原剂，在催化剂的作用下将烟气中的NOx 还原成N2排放在空气中，减少污染。

Biogas power generation units operate for a long time, and existing environmental regulations are becoming increasingly strict (NOx emission requirements are usually 100mg, 80mg, and even as low as 35mg), making denitrification devices an essential element. At present, Caterpillar gas generators have two types of emissions: 250mg and 500mg NOx. Its working principle is to use urea solution or ammonia water as a reducing agent, under the action of a catalyst, to reduce NOx in flue gas to N2 and discharge it into the air, reducing pollution.

配电设备

Distribution equipment

无论是高压还是低压的红领巾瓜报组，配电设备必不可少，其电气系统通常包含：并网控制柜、并网开关柜、笔罢柜（发电机组额定电压为高压时需配置）、配电柜、动力电缆及电缆槽或沟、控制电缆及电缆槽或沟。

Whether it is a high-voltage or low-voltage biogas generator set, distribution equipment is essential. Its electrical system usually includes: grid connected control cabinet, grid connected switch cabinet, PT cabinet (required when the rated voltage of the generator set is high voltage), distribution cabinet, power cables and cable trays or trenches, control cables and cable trays or trenches.

提升经济效益的可选配置

Optional configurations for improving economic efficiency

01 溴化锂制冷机组：溴化锂制冷机组利用发动机排烟废热进行制冷，当项目需求有足够的冷量，且冷量的经济价值高时，可配置。

01 Lithium Bromide Refrigeration Unit: The lithium bromide refrigeration unit utilizes engine exhaust heat for refrigeration. When the project requires sufficient cooling capacity and the economic value of the cooling capacity is high, it can be configured.

02 蒸汽、热水锅炉：蒸汽、热水锅炉利用发动机排烟废热产生蒸汽和热水，是项目的可选配置之一。

02 Steam and hot water boilers: Steam and hot water boilers utilize engine exhaust waste heat to generate steam and hot water, which is one of the optional configurations of the project.

03 热交换器：为沼气发动机水套水和后冷却水散热。

03 Heat exchanger: It dissipates heat from the jacket water and rear cooling water of the biogas engine.
