1、在收集速率的前提下，尽可能降低排风量，这样既可提升排气浓度提升废气单位热值，又可降低风量降低能耗。同时也要考虑热将尾气中热量进行回收。

　　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、废气一般属于易燃易爆性气体，虽然浓度好可以回收利用物燃烧产生的部分热量，降低能耗，但在处理中要将其浓度控制在爆炸限范围内。在能耗可接受范围的情况下，小风量一般采用简易的列管直接热交换回收热。

　　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、催化燃烧需要在相应的温度条件下进行，对于低温气体要进行加热，风量越大其耗能越大，运行成本也提升。

　　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、催化燃烧一般适用于小风量、浓度好、温度高的气态物，且废气中不能含有硫、铅、汞、砷及卤素等可使催化剂中毒的因子。

　　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、废气处理中常用的催化一般为蜂窝状钯金属催化剂和铂金属催化剂，催化燃烧方式有电加热和燃气加热，燃烧类型有直接催化燃烧和蓄热式催化燃烧。

　　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.
