1、在收集速率的前提下，盡可能降低排風量，這樣既可提升排氣濃度提升廢氣單位熱值，又可降低風量降低能耗。同時也要考慮熱將尾氣中熱量進行回收。

　　1. Under the premise of collection rate, try to reduce the exhaust volume as much as possible, which can not only increase the exhaust concentration and increase the unit heat value of exhaust gas, but also reduce the air volume and energy consumption. At the same time, it is also necessary to consider recovering the heat from the exhaust gas.

　　2、廢氣一般屬于易燃易爆性氣體，雖然濃度好可以回收利用物燃燒產生的部分熱量，降低能耗，但在處理中要將其濃度控制在爆炸限范圍內。在能耗可接受范圍的情況下，小風量一般采用簡易的列管直接熱交換回收熱。

　　2. Waste gas is generally a flammable and explosive gas. Although it can recover and utilize some of the heat generated by the combustion of materials and reduce energy consumption with good concentration, its concentration should be controlled within the explosion limit during treatment. In the acceptable range of energy consumption, small air volumes generally use simple tube direct heat exchange to recover heat.

　　3、催化燃燒需要在相應的溫度條件下進行，對于低溫氣體要進行加熱，風量越大其耗能越大，運行成本也提升。

　　3. Catalytic combustion needs to be carried out under corresponding temperature conditions, and low-temperature gases need to be heated. The larger the air volume, the greater the energy consumption and the higher the operating cost.

　　4、催化燃燒一般適用于小風量、濃度好、溫度高的氣態物，且廢氣中不能含有硫、鉛、汞、砷及鹵素等可使催化劑中毒的因子。

　　4. Catalytic combustion is generally suitable for gaseous substances with low air volume, good concentration, and high temperature, and the exhaust gas should not contain factors such as sulfur, lead, mercury, arsenic, and halogens that can poison the catalyst.

　　5、廢氣處理中常用的催化一般為蜂窩狀鈀金屬催化劑和鉑金屬催化劑，催化燃燒方式有電加熱和燃氣加熱，燃燒類型有直接催化燃燒和蓄熱式催化燃燒。

　　5. The commonly used catalysts in exhaust gas treatment are honeycomb shaped palladium metal catalysts and platinum metal catalysts. Catalytic combustion methods include electric heating and gas heating, and combustion types include direct catalytic combustion and regenerative catalytic combustion.
