想買(mǎi)發(fā)電機(jī)又不知道怎么選？那么我們給您推薦：

Want to buy a generator but don't know how to choose? So we recommend to you:

1.你先確定需要多大功率的發(fā)電機(jī)？首先從你的用電功率考慮，什么設(shè)備要供電，功率多大，怎么啟動(dòng)？假設(shè)是個(gè)電機(jī)，直接啟動(dòng)，那就需要3-7倍大的發(fā)電機(jī)組。假設(shè)是家庭停電用，一個(gè)小型汽油機(jī)足矣。如果是銀行、財(cái)務(wù)電腦怕停電，那一個(gè)ups電源就夠了。

1. What power generator do you need first? Firstly, considering your power consumption, what equipment needs to be powered, how much power is required, and how to start it? Assuming it is an electric motor, starting directly would require a generator set that is 3-7 times larger. Assuming it is for household power outages, a small gasoline engine is sufficient. If banks or financial computers are afraid of power outages, then one UPS power supply is enough.

2.確定好功率，再選品牌。如果是柴油發(fā)電機(jī)，因?yàn)椴裼桶l(fā)電機(jī)功率段較廣，涵蓋20kw-2000kw的，還有自啟動(dòng)，自動(dòng)化，高壓啥的，挺多種類(lèi)。重要的是柴油機(jī)和發(fā)電機(jī)的品牌，一搜就知道幾大著名的品牌，康明斯，濰柴，玉柴，沃爾沃，排名不分先后。選哪個(gè)看你的具體情況，看使用頻率和場(chǎng)景。

2. Determine the power and then choose the brand. If it is a diesel generator, because the power range of diesel generators is relatively wide, covering 20kW-2000kw, as well as self starting, automation, high voltage, etc., there are many types. What's important are the brands of diesel engines and generators. A quick search reveals several famous brands, such as Cummins, Weichai, Yuchai, and Volvo, ranked in no particular order. Which one to choose depends on your specific situation, frequency of use, and scenario.

3.選廠家，主要選大廠家，看規(guī)模和業(yè)績(jī)，看服務(wù)。

3. Choose manufacturers, mainly large manufacturers, based on scale and performance, and service.

還有其他的發(fā)電機(jī)，比如焦?fàn)t煤氣發(fā)電機(jī)組性能好，焦?fàn)t煤氣發(fā)熱值高，在生產(chǎn)正常是，煤氣熱值波動(dòng)不大，便于調(diào)火操作。

There are other generators, such as coke oven gas generators, which have good performance and high calorific value of coke oven gas. In normal production, the fluctuation of gas calorific value is not significant, making it easy to adjust the ignition.

用高爐煤氣加熱焦?fàn)t是，由于他的熱值高，需要的煤氣量就比熱值低的煤氣少，這樣，產(chǎn)生的廢氣量就少。而且，廢氣的重度又比較小，所以焦?fàn)t加熱系統(tǒng)阻力也小些。

Heating a coke oven with blast furnace gas requires less gas due to its high calorific value, resulting in less waste gas production. Moreover, the severity of exhaust gas is relatively low, so the resistance of the coke oven heating system is also lower.

在調(diào)節(jié)溫度時(shí)，增減煤氣用量后，爐溫變化反映較快，一般需要2-3h小時(shí)爐溫就可以反映出來(lái)。在焦?fàn)t煤氣燃燒產(chǎn)生的廢氣中，存在有大量的水蒸氣、二氧化碳和游離碳等，這些多原子氣體具有相當(dāng)大的輻射能力，可是火道中輻射傳熱加快。

When adjusting the temperature, the change in furnace temperature is reflected quickly after increasing or decreasing the amount of gas used. Generally, it takes 2-3 hours for the furnace temperature to reflect. In the exhaust gas generated by the combustion of coke oven gas, there are a large amount of water vapor, carbon dioxide, and free carbon. These multi atomic gases have considerable radiation ability, but the radiation heat transfer in the furnace is accelerated.

焦?fàn)t煤氣含氫多，不可燃成分少，燃燒速度快，火焰較短。在焦?fàn)t加熱時(shí)，會(huì)使焦餅上下溫差變化較大，這對(duì)調(diào)火是不利的。

Coke oven gas contains more hydrogen, less non combustible components, burns quickly, and has a shorter flame. When heating in a coke oven, the temperature difference between the top and bottom of the coke cake will vary greatly, which is not conducive to adjusting the ignition.

焦?fàn)t煤氣含碳?xì)浠衔锒啵邷啬芊纸獬鍪?，這些石墨容易在燒嘴上掛結(jié)，影響燃燒。

Coke oven gas contains a lot of hydrocarbons, which can decompose into graphite at high temperatures. These graphite particles are prone to hang on the burner and affect combustion.

焦?fàn)t煤氣與空氣混合到一定的比例時(shí)，可形成爆炸性氣體，遇到火源就會(huì)爆炸。焦?fàn)t煤氣的爆炸范圍為6-30%。

When coke oven gas is mixed with air to a certain ratio, it can form explosive gases that will explode when exposed to a fire source. The explosion range of coke oven gas is 6-30%.
