In the past decade, due to the rapid development of society, the importance of environmental protection and the shortage of energy, the state has paid more and more attention to energy conservation. With the further development of energy-saving work, all kinds of new energy-saving advanced furnace models are gradually improved, and new fire-resistant fiber and other high-quality insulation materials are used, so that the heat loss of furnace body is significantly reduced. Advanced combustion device is adopted to improve combustion efficiency, reduce incomplete combustion and make air-fuel ratio more reasonable.

　　但是，降低煙氣熱損失和回收煙氣余熱的技術進展緩慢。為了進一步提高窯爐的熱效率，達到節(jié)能降耗的目的，煙氣余熱回收也是節(jié)能的重要途徑。

　　However, the technology of reducing the heat loss of flue gas and recovering the residual heat of flue gas has made slow progress. In order to further improve the thermal efficiency of the kiln and achieve the purpose of energy saving and consumption reduction, flue gas waste heat recovery is also an important way of energy saving.

　　煙氣是一般耗能設備浪費能量的主要途徑，煙氣余熱回收主要是通過某種傳熱方法將煙氣攜帶的熱量轉化為可用的熱量。

　　Flue gas is the main way to waste energy in general energy consuming equipment. Flue gas waste heat recovery is mainly to convert the heat carried by flue gas into available heat through some heat transfer method.

　　1、 Recovery method of waste heat from flue gas of gas generator set

　　煙氣余熱回收通常采用兩種方法:一是對工件進行預熱;第二種是使空氣變暖以供燃燒。煙氣預熱工件需要占用較大的換熱空間，這往往受到工作場所的限制(間歇式加熱爐不能采用這種方法)。預熱空氣燃燒是一種較好的方法，一般配置在加熱爐中，還可以增強燃燒，加快加熱爐的升溫速度，提高加熱爐的熱工性能。這既滿足了工藝要求，又能取得顯著的綜合節(jié)能效果。

　　There are two methods for flue gas waste heat recovery: one is preheating the workpiece; the other is warming the air for combustion. The preheating of workpieces by flue gas needs to occupy a large heat exchange space, which is often limited by the workplace (this method cannot be used for intermittent heating furnace). Preheating air combustion is a better method, which is generally configured in the heating furnace. It can also enhance combustion, accelerate the heating speed of the heating furnace, and improve the thermal performance of the heating furnace. This not only meets the process requirements, but also achieves significant comprehensive energy saving effect.

　　二、其他回收煙氣余熱的方法:

　　2、 Other recovery methods of flue gas residual heat:

　　1. 余熱回收裝置(氣水):熱管余熱回收裝置是燃煤、石油、燃氣鍋爐的專用設備。安裝在鍋爐的煙口，回收煙氣余熱，加熱生活用水或鍋爐補水。

　　1. Waste heat recovery device (gas water): the heat pipe waste heat recovery device is a special equipment for coal, oil and gas boilers. It is installed at the flue gas port of the boiler to recover the residual heat of flue gas, heat domestic water or make-up water for the boiler.

　　2. 廢熱回收器(氣-氣)

　　2. Waste heat recovery device (gas gas)

　　熱管余熱回收裝置是燃油、煤炭、燃氣鍋爐的專用設備。它安裝在鍋爐的煙道或煙道中，在回收煙氣的余熱后對空氣進行加熱。熱風可作為鍋爐燃燒和干燥的物料。余熱回收裝置出口煙氣溫度不得低于露點。

　　Heat pipe waste heat recovery device is a special equipment for oil, coal and gas boilers. It is installed in the flue or flue of the boiler to heat the air after the waste heat of the flue gas is recovered. Hot air can be used as materials for boiler combustion and drying. The flue gas temperature at the outlet of waste heat recovery device shall not be lower than the dew point.
