　　3.配套設備應與燃機主機設備具備相當的使用壽命，并保證安全經濟性能在合理的使用壽命期內滿足要求。

　　3. The supporting equipment should have a comparable service life to the main equipment of the gas turbine, and ensure that the safety and economic performance meet the requirements within a reasonable service life.

　　六、聯合循環(huán)設備現場布置

　　6、 On site layout of combined cycle equipment

　　1.根據燃氣發(fā)電項目的實際情況選擇燃機、汽輪機和發(fā)電機、余熱鍋爐等主機設備的布置方式，設備布置兼顧設備安裝和檢修維護需要。

　　1. Choose the layout of main equipment such as gas turbines, steam turbines, generators, and waste heat boilers based on the actual situation of the gas-fired power generation project, taking into account the needs of equipment installation and maintenance.

　　2.對于熱電聯產燃氣機組，考慮機組供熱和運行靈活性，優(yōu)先選擇燃機、汽輪機分軸布置方式，以保證在汽輪機出現故障時的供熱需要。

　　2. For cogeneration gas-fired units, considering the flexibility of unit heating and operation, priority should be given to the arrangement of separate shafts for gas and steam turbines to ensure the heating needs in case of turbine failure.

　　3.對于發(fā)電調峰用沼氣發(fā)電機組，燃機、汽輪機可采用更為緊湊的同軸布置方式，系統(tǒng)相對簡單，占地面積較小，投資費用較低。

　　3. For biogas generators used for peak shaving power generation, the gas turbine and steam turbine can be arranged in a more compact coaxial manner, with a relatively simple system, smaller footprint, and lower investment costs.

　　4.燃機、汽機等主設備可采用高位或低位布置方式，可根據場地和造價情況等因素進行綜合評估后選擇。

　　4. The main equipment such as gas turbines and steam turbines can be arranged in a high or low position, and can be selected after comprehensive evaluation based on factors such as site and cost.

　　七、燃機技術路線和設備選擇步驟

　　7、 Technical roadmap and equipment selection steps for gas turbines

　　1.根據區(qū)域能源需求現狀和近期、遠期規(guī)劃并考慮裕量。

　　1. Based on the current state of regional energy demand and short-term and long-term planning, and considering margin.

　　2.確定用能的種類和供能方式。

　　2. Determine the type of energy used and the method of energy supply.

　　3.確定采用熱電聯產、調峰或分布式技術類型。

　　3. Determine the type of cogeneration, peak shaving, or distributed technology to be adopted.

　　4.確定燃機設備的容量及數量。

　　4. Determine the capacity and quantity of gas turbine equipment.

　　5.燃機設備選型。

　　5. Selection of gas turbine equipment.

　　6.燃機配套汽輪機、發(fā)電機設備選擇。

　　6. Selection of matching steam turbine and generator equipment for gas turbine.

　　7.余熱鍋爐及其輔機設備選擇。

　　7. Selection of waste heat boiler and its auxiliary equipment.
