燃?xì)獍l(fā)電機的熱耗率計算以及提高
由于燃?xì)獍l(fā)電機需要較少的組件來產(chǎn)生所需的能量，因此它們的維護成本低。它們的燃料消耗率低于其他類型的發(fā)電機，使其具有燃油效率，并且燃?xì)獍l(fā)電機非常耐用，可以承受壓力條件而不會出現(xiàn)故障。下面說說燃?xì)獍l(fā)電機熱耗率的計算和改進(jìn)。
Since gas-fired generators require fewer components to generate the required energy, their maintenance costs are low. Their fuel consumption rate is lower than that of other types of generators, making them fuel efficient, and gas-fired generators are very durable and can withstand pressure conditions without failure. Let's talk about the calculation and improvement of heat rate of gas generator.
燃?xì)獍l(fā)電機熱耗率計算
Calculation of heat rate of gas generator
熱耗率計算通常以每千瓦時(kWh)的英熱單位(Btu)進(jìn)行。簡而言之，發(fā)電機的熱效率，通過將燃料燃燒產(chǎn)生的能量除以該過程中產(chǎn)生的電能的總輸出來計算。簡而言之，熱耗率值越低，效率越好。燃?xì)獍l(fā)電機的熱耗值可以根據(jù)某些方面進(jìn)行推斷。讓我們分別看一下：
The heat rate calculation is usually carried out in British thermal units (BTU) per kilowatt hour (KWH). In short, the thermal efficiency of a generator is calculated by dividing the energy generated by fuel combustion by the total output of electrical energy generated in the process. In short, the lower the heat rate value, the better the efficiency. The heat consumption value of gas generator can be inferred from some aspects. Let's take a look at:
燃料成本。發(fā)電機的性能很少每天都保持不變。它的輸出在不同的日子可能不同，因此很難計算出確切的效率。這種容量變化會產(chǎn)生不同的熱消耗率，這將影響燃料成本?？?cè)剂铣杀究梢酝ㄟ^將熱耗率乘以每Btu的總?cè)剂铣杀緛碛嬎恪?/div>
Fuel cost. The performance of the generator rarely remains the same every day. Its output may be different on different days, so it is difficult to calculate the exact efficiency. This capacity change will result in different heat consumption rates, which will affect the fuel cost. The total fuel cost can be calculated by multiplying the heat rate by the total fuel cost per BTU.
熱率退化。燃?xì)獍l(fā)電機組的熱消耗率隨著其發(fā)電能力或發(fā)電效率的增加而降低。據(jù)估計，單循環(huán)機組的熱耗率每年下降0.2%，而聯(lián)合循環(huán)機組的熱耗率每年下降0.05%。
Heat rate degradation. The heat consumption rate of gas-fired generator sets decreases with the increase of its power generation capacity or power generation efficiency. It is estimated that the heat rate of single cycle units will decrease by 0.2% annually, while that of combined cycle units will decrease by 0.05% annually.
提高燃?xì)獍l(fā)電機的效率
Improve the efficiency of gas generator
發(fā)電機的效率可以在一段時間內(nèi)得到提高，并且在可控范圍內(nèi)。它的效率取決于所用燃料的質(zhì)量、設(shè)備的質(zhì)量以及您如何維護它。也就是說，還有一些明確的方法可以提高其效率。所有發(fā)電機的設(shè)計都旨在實現(xiàn)好性能，并在頻譜的提供能量輸出。
The efficiency of the generator can be improved in a period of time and within a controllable range. Its efficiency depends on the quality of the fuel used, the quality of the equipment, and how you maintain it. In other words, there are some clear ways to improve its efficiency. All generators are designed to achieve good performance and provide energy output at the high end of the spectrum.
然而，燃?xì)獍l(fā)電機在其設(shè)計負(fù)載能力以下運行的常見問題之一是積碳。當(dāng)發(fā)電機在低溫下耗盡未燃燒的燃料時，就會發(fā)生這種情況。這會在生成器中創(chuàng)建一個阻塞系統(tǒng)，從而降低其性能。為避免這種情況，請在其一定合適的范圍內(nèi)操作發(fā)電機。
However, one of the common problems of gas-fired generators operating below their design load capacity is carbon deposition. This occurs when the generator runs out of unburned fuel at low temperatures. This creates a blocking system in the generator, reducing its performance. To avoid this, please operate the generator within its proper range.
長時間在輕負(fù)載下運行燃?xì)獍l(fā)電機組可能對其健康產(chǎn)生不利影響。這會導(dǎo)致頻繁的停機、更多的維護以及整體保質(zhì)期縮短。在良好的范圍內(nèi)使用機器是保持機器長時間運行的好方法。
Long-term operation of gas-fired generator units under light load may have adverse effects on their health. This results in frequent downtime, more maintenance, and a shorter overall shelf life. Using the machine in a good range is a good way to keep the machine running efficiently for a long time.
