在分布式能源項目中，燃氣發(fā)電機組是其重要的組成部分，燃氣發(fā)電機組選型目標是選擇一款與項目應用相匹配，在項目應用中經(jīng)濟性的設備。接下來(lái)簡(jiǎn)單講一下選型時(shí)需要考慮的指標有哪些？

In the distributed energy project, the gas generator set is an important component. The selection goal of the gas generator set is to select a device that matches the project application and is economical in the project application. Next, let's talk about the indicators that need to be considered when selecting models?

1，框架性參數

1. Frame parameters

燃氣發(fā)電機組使用范圍和使用方式；燃氣發(fā)電機組型號、輸出電壓、頻率、適用燃氣的品質(zhì)、排放指標、低溫冷卻水進(jìn)水溫度和高溫冷卻水出口溫度等。

Scope and mode of use of gas-fired generating units; Model, output voltage, frequency, quality of applicable gas, emission index, inlet temperature of low-temperature cooling water and outlet temperature of high-temperature cooling water of gas-fired generator set.

2，燃氣消耗指標

2. Gas consumption index

燃氣消耗量或發(fā)電效率，余熱利用效率對于項目的投資回收周期，發(fā)電成本有著(zhù)至關(guān)重要的作用。

Gas consumption or power generation efficiency and waste heat utilization efficiency play a vital role in the investment recovery cycle and power generation cost of the project.

3，發(fā)動(dòng)機指標

3. Engine index

燃氣發(fā)電機組核心是燃氣發(fā)動(dòng)機，燃氣發(fā)動(dòng)機性能至關(guān)重要。燃氣發(fā)動(dòng)機的技術(shù)參數包括：生產(chǎn)商、發(fā)動(dòng)機缸數、缸徑、沖程、排量、吸氣方式、機械輸出功率、汽缸平均壓力、額定轉速、壓縮比、潤滑油消耗量、要求燃氣的工作壓力及所能適用的燃料較小甲烷值、啟動(dòng)方式和發(fā)電機組尺寸和重量。

The core of gas generator set is gas engine, and the performance of gas engine is very important. The technical parameters of the gas engine include: manufacturer, engine cylinder number, cylinder diameter, stroke, displacement, suction mode, mechanical output power, average cylinder pressure, rated speed, compression ratio, lubricating oil consumption, working pressure of the required gas and the smaller methane value of the applicable fuel, starting mode, size and weight of the generator set.

4，熱平衡指標

4. Heat balance index

在分布式能源項目中，余熱利用是項目的另一個(gè)重要組成部分，燃氣發(fā)電機組熱平衡指標是項目余熱利用設計的基礎。

In distributed energy projects, waste heat utilization is another important part of the project, and the heat balance index of gas generator set is the basis of waste heat utilization design of the project.

5，進(jìn)排氣指標

5. Intake and exhaust indexes

燃氣發(fā)動(dòng)機所允許的進(jìn)氣阻力和排氣阻力、溫度和流量是機房通風(fēng)設計及排煙系統余熱利用設計中的重要參數。所有機房通風(fēng)設計、余熱利用等須滿(mǎn)足發(fā)電機組滿(mǎn)載運行的要求。

The allowable intake and exhaust resistance, temperature and flow of gas engine are important parameters in the ventilation design of machine room and the waste heat utilization design of exhaust system. The ventilation design and waste heat utilization of all machine rooms must meet the requirements of full load operation of the generator unit.

6，功率折損

6. Power loss

發(fā)動(dòng)機功率折損是燃氣發(fā)電機組一個(gè)非常重要的參數。它反映了發(fā)動(dòng)機在不同海拔和不同氣溫下燃氣發(fā)動(dòng)機能夠輸出的實(shí)際功率。

Engine power loss is a very important parameter of gas generator set. It reflects the actual power that the gas engine can output at different altitudes and temperatures.

燃氣發(fā)電機組選型時(shí)需要考慮什么指標呢？實(shí)際上在這里講了六大方面的指標，所以您在進(jìn)行選型時(shí)也可以作為內容借鑒下，希望給您幫助，更多信息就來(lái)我們網(wǎng)站http://m.elmasticar.com獲取吧。
