常有客戶的采購主管咨詢“燃氣發電機組選型該從何入手？”“燃氣信息、環境條件對選擇機組有啥用？”，小編將通過系列專題來深入淺出地解答您的疑惑。

　　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.

　　首先，配置燃氣機組需要了解以下三類信息，每類還有若干項需考慮的因素。

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

　　· 燃氣信息用于確定Cat機組類型及功率段的選擇；

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

　　· 環境條件主要是指地理條件因素，將影響機組的輸出功率及加裝配置的選擇；

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

　　· 項目應用需求主要針對項目應用區域及應用場景差異導致的輔助設備的不同配置。

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

　　本主題信息含量密集，我們將分期逐類逐項給粉絲們具體解析。

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

　　燃氣信息

　　Gas information

　　燃氣是我們燃氣發電機組的燃料，其在配置燃氣發電機組中占有重要的地位。

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

　　1、燃氣種類

　　1. Gas type

　　燃氣種類包括以下幾大類：天然氣，沼氣 ，石油伴生氣，垃圾填埋氣，煤層氣，液化氣油氣

　　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、發動機應用

　　2. Engine application

　　卡特彼勒按照不同的氣體種類將燃氣發動機分為：

　　Caterpillar classifies gas engines according to different types of gases:

　　弄清氣體的種類，選擇正確的發動機。

　　Identify the type of gas and choose the correct engine.

　　燃氣信息包含的內容

　　The content contained in gas information

　　1、燃氣壓力

　　1. Gas pressure

　　燃氣壓力大小和波動范圍：

　　Gas pressure magnitude and fluctuation range:

　　Cat燃氣發動機氣體壓力20-200mbar。不同的燃氣壓力配制不同的發動機混合器。

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

　　波動范圍：≤±10%。若燃氣波動范圍大于此要求時，請在發動機燃氣進氣閥組(Gas train)前加裝穩壓閥，或在項目設計中增加儲氣罐來穩定壓力的波動。

　　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、燃氣氣量與成份

　　2. Gas volume and composition

　　燃氣的成分決定了燃氣的甲烷值和低熱值，而燃氣的甲烷值和低熱值將決定發動機的應用。對于沼氣類發電機組，需要盡可能利用所有的沼氣。此時，我們機組功率的選型主要取決于沼氣的流量與沼氣的成份組成，我們會根據客戶工廠整體的能源利用情況匹配最佳機型和數量。

　　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、有害物質的濃度

　　3. Concentration of harmful substances

　　氣體中如含有害物質，且其濃度超過一定范圍，則必須進行氣體處理后才能作為發動機燃料。有害物質如硫化氫、鹵化物、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.
