想买发电机又不知道怎么选？那么我们给您推荐：

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

1.你先确定需要多大功率的发电机？首先从你的用电功率考虑，什么设备要供电，功率多大，怎么启动？假设是个电机，直接启动，那就需要3-7倍大的发电机组。假设是家庭停电用，一个小型汽油机足矣。如果是银行、财务电脑怕停电，那一个ups电源就够了。

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.确定好功率，再选品牌。如果是柴油发电机，因为柴油发电机功率段较广，涵盖20kw-2000kw的，还有自启动，自动化，高压啥的，挺多种类。重要的是柴油机和发电机的品牌，一搜就知道几大著名的品牌，康明斯，潍柴，玉柴，沃尔沃，排名不分先后。选哪个看你的具体情况，看使用频率和场景。

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.选厂家，主要选大厂家，看规模和业绩，看服务。

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

还有其他的发电机，比如焦炉煤气发电机组性能好，焦炉煤气发热值高，在生产正常是，煤气热值波动不大，便于调火操作。

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.

用高炉煤气加热焦炉是，由于他的热值高，需要的煤气量就比热值低的煤气少，这样，产生的废气量就少。而且，废气的重度又比较小，所以焦炉加热系统阻力也小些。

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.

在调节温度时，增减煤气用量后，炉温变化反映较快，一般需要2-3h小时炉温就可以反映出来。在焦炉煤气燃烧产生的废气中，存在有大量的水蒸气、二氧化碳和游离碳等，这些多原子气体具有相当大的辐射能力，可是火道中辐射传热加快。

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.

焦炉煤气含氢多，不可燃成分少，燃烧速度快，火焰较短。在焦炉加热时，会使焦饼上下温差变化较大，这对调火是不利的。

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.

焦炉煤气含碳氢化合物多，高温能分解出石墨，这些石墨容易在烧嘴上挂结，影响燃烧。

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.

焦炉煤气与空气混合到一定的比例时，可形成爆炸性气体，遇到火源就会爆炸。焦炉煤气的爆炸范围为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%.
