常有客户的采购主管咨询“燃气发电机组选型该从何入手？”“燃气信息、环境条件对选择机组有啥用？”，小编将通过系列专题来深入浅出地解答您的疑惑。

　　Customers' purchasing supervisors often inquire about "where to start when selecting gas generator sets?" "What is the use of gas information and environmental conditions for selecting units?" The editor will answer your questions in a series of topics in a simple and understandable way.

　　，配置燃气机组需要了解以下三类信息，每类还有若干项需考虑的因素。

　　Firstly, to configure a gas turbine, it is necessary to understand the following three types of information, each with several factors to consider.

　　· 燃气信息用于确定Cat机组类型及功率段的选择；

　　·Gas information is used to determine the type and power range selection of Cat units;

　　· 环境条件主要是指地理条件因素，将影响机组的输出功率及加装配置的选择；

　　·Environmental conditions mainly refer to geographical factors that will affect the output power of the unit and the selection of installation configurations;

　　· 项目应用需求主要针对项目应用区域及应用场景差异导致的辅助设备的不同配置。

　　·The project application requirements mainly target the different configurations of auxiliary equipment caused by differences in project application areas and scenarios.

　　本主题信息含量密集，我们将分期逐类逐项给粉丝们具体解析。

　　The information content of this topic is dense, and we will provide fans with specific analysis in stages, categories, and items.

　　燃气信息

　　Gas information

　　燃气是我们燃气发电机组的燃料，其在配置燃气发电机组中占有重要的地位。

　　Gas is the fuel for our gas generator sets, and it plays an important role in the configuration of gas generator sets.

　　1、燃气种类

　　1. Gas type

　　燃气种类包括以下几大类：天然气，沼气 ，石油伴生气，垃圾填埋气，煤层气，液化气油气

　　The types of gas include the following categories: natural gas, biogas, petroleum associated gas, landfill gas, coalbed methane, liquefied gas, and oil and gas

　　2、发动机应用

　　2. Engine application

　　卡特彼勒按照不同的气体种类将燃气发动机分为：

　　Caterpillar classifies gas engines according to different types of gases:

　　弄清气体的种类，选择正确的发动机。

　　Identify the type of gas and choose the correct engine.

　　燃气信息包含的内容

　　The content contained in gas information

　　1、燃气压力

　　1. Gas pressure

　　燃气压力大小和波动范围：

　　Gas pressure magnitude and fluctuation range:

　　Cat燃气发动机气体压力20-200mbar。不同的燃气压力配制不同的发动机混合器。

　　Cat gas engine gas pressure is 20-200mbar. Different engine mixers are prepared for different gas pressures.

　　波动范围：≤±10%。若燃气波动范围大于此要求时，请在发动机燃气进气阀组(Gas train)前加装稳压阀，或在项目设计中增加储气罐来稳定压力的波动。

　　Fluctuation range: ≤± 10%. If the gas fluctuation range exceeds this requirement, please install a pressure regulator valve before the engine gas intake valve group (Gas train), or add a gas storage tank in the project design to stabilize the pressure fluctuation.

　　2、燃气气量与成份

　　2. Gas volume and composition

　　燃气的成分决定了燃气的甲烷值和低热值，而燃气的甲烷值和低热值将决定发动机的应用。对于沼气类发电机组，需要尽可能利用所有的沼气。此时，我们机组功率的选型主要取决于沼气的流量与沼气的成份组成，我们会根据客户工厂整体的能源利用情况匹配机型和数量。

　　The composition of gas determines its methane value and low calorific value, and the methane value and low calorific value of gas will determine the application of the engine. For biogas generator sets, it is necessary to utilize all biogas as much as possible. At this point, the selection of our unit power mainly depends on the flow rate and composition of biogas. We will match the optimal model and quantity based on the overall energy utilization of the customer's factory.

　　3、有害物质的浓度

　　3. Concentration of harmful substances

　　气体中如含有害物质，且其浓度超过一定范围，则必须进体处理后才能作为发动机燃料。有害物质如硫化氢、卤化物、氨等。

　　If harmful substances are present in the gas and their concentration exceeds a certain range, gas treatment must be carried out before it can be used as engine fuel. Harmful substances such as hydrogen sulfide, halides, ammonia, etc.
