在分布式能源項目中，燃?xì)獍l(fā)電機組是其重要的組成部分，燃?xì)獍l(fā)電機組選型目標(biāo)是選擇一款與項目應(yīng)用相匹配，在項目應(yīng)用中經(jīng)濟性的設(shè)備。接下來簡單講一下選型時需要考慮的指標(biāo)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(shù)

1. Frame parameters

燃?xì)獍l(fā)電機組使用范圍和使用方式；燃?xì)獍l(fā)電機組型號、輸出電壓、頻率、適用燃?xì)獾钠焚|(zhì)、排放指標(biāo)、低溫冷卻水進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?xì)庀闹笜?biāo)

2. Gas consumption index

燃?xì)庀牧炕虬l(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)動機指標(biāo)

3. Engine index

燃?xì)獍l(fā)電機組核心是燃?xì)獍l(fā)動機，燃?xì)獍l(fā)動機性能至關(guān)重要。燃?xì)獍l(fā)動機的技術(shù)參數(shù)包括：生產(chǎn)商、發(fā)動機缸數(shù)、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(zhuǎn)速、壓縮比、潤滑油消耗量、要求燃?xì)獾墓ぷ鲏毫八苓m用的燃料較小甲烷值、啟動方式和發(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(biāo)

4. Heat balance index

在分布式能源項目中，余熱利用是項目的另一個重要組成部分，燃?xì)獍l(fā)電機組熱平衡指標(biāo)是項目余熱利用設(shè)計的基礎(chǔ)。

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，進排氣指標(biāo)

5. Intake and exhaust indexes

燃?xì)獍l(fā)動機所允許的進氣阻力和排氣阻力、溫度和流量是機房通風(fēng)設(shè)計及排煙系統(tǒng)余熱利用設(shè)計中的重要參數(shù)。所有機房通風(fēng)設(shè)計、余熱利用等須滿足發(fā)電機組滿載運行的要求。

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)動機功率折損是燃?xì)獍l(fā)電機組一個非常重要的參數(shù)。它反映了發(fā)動機在不同海拔和不同氣溫下燃?xì)獍l(fā)動機能夠輸出的實際功率。

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?xì)獍l(fā)電機組選型時需要考慮什么指標(biāo)呢？實際上在這里講了六大方面的指標(biāo)，所以您在進行選型時也可以作為內(nèi)容借鑒下，希望給您幫助，更多信息就來我們網(wǎng)站http://m.hdlelisa.com獲取吧。
