Difference Between Incineration and Pyrolysis

关键区别 - 焚化与热解

焚化和热解都是燃烧的形式，即物质的热分解。根据氧气对燃烧过程的需求，它们彼此不同。这key difference between incineration and pyrolysis is that焚化是在氧气存在下有机物的燃烧，而热解是在没有氧气的情况下有机物的燃烧。

What is Incineration?

焚化is the燃烧of organic matter in the presence of oxygen. It is one of the major ways of destroying waste materials. It is a type of thermal treatment carried at very high temperature. The incineration process converts waste into ash, gases (flue gas) and heat. The heat generated from this treatment can be used to generate electricity.

Incinerators are used in large-scale incineration processes. Earliest incinerators had no steps of material separation to separate materials that are hazardous, bulky or recyclable. Modern incinerators are more advanced and make use of all useful matter included in waste. These incinerators have pollution mitigation equipment (for flue gas cleaning). Modern incinerators reduce the mass of waste by 80%. The volume is reduced by around 95%.

这re are severalmethods进行焚化过程：

1. Burn pile– includes burning combustible material piles on the ground in an open area.
2. 燃烧桶– the combustible material is placed inside a metal barrel and is burnt. This method avoids the spread of burning materials and the ash produced at the end of the incineration settle down to the bottom of the barrel.
3. Rotary-kiln– A rotary-kiln is a type of incinerator. These incinerators are used in industrial scale applications. It has more equipment, and the incineration process is more advanced and complicated.
4. 流化床– this method includes passing heated air through a sand bed until a fluidized bed condition is created. Then the waste particles are introduced into this fluidized bed.
5. 移动炉排- 这是市政废物管理过程中使用的典型焚化炉类型。燃烧更有效，是一个完整的

缺点of incineration include followings:

• 焚化reduces the recycling of recyclable materials because burning is easier and cheaper than recycling.
• 焚化releases gaseous components such as carbon dioxide (CO2).
• 焚化emits hazardous end products.
• 焚化can lead to different health risks.

什么是热解?

热解是在没有氧气的情况下有机物的燃烧。This is a thermal decomposition carried out in an inert atmosphere such as in the presence of vacuum gas. The chemical composition of the material is changed by this process, and the process is irreversible.

通常，有机材料的热解会导致挥发性成分以及含碳的固体残基和焦油的产生。该过程还为固相，液相和气相提供最终产物。热解在430°C以上的温度下进行。碳化是一种热解的形式，它留下了富含碳的固体残基。

热解的使用are as follows:

1. Ethylene production
2. Production of tar
3. Production of biofuels from biomass.

What are the Similarities Between Incineration and Pyrolysis?

• Both incineration and pyrolysis include burning of materials.
• 这两个过程都产生气态化合物作为最终产品。

What is the Difference Between Incineration and Pyrolysis?

焚化vs Pyrolysis
焚化is the combustion of organic matter in the presence of oxygen.	热解是在没有氧气的情况下有机物的燃烧。
气氛
在氧气存在下进行焚化。	Pyrolysis is done in the absence of oxygen.
End Products
焚化produces ash and gases.	Pyrolysis produces gaseous components along with trace amounts of liquid and solid residues.

摘要 - 焚化与热解

焚化and pyrolysis are thermal decomposition methods. The key difference between incineration and pyrolysis is that incineration is the combustion of organic matter in the presence of oxygen whereas pyrolysis is the combustion of organic matter in the absence of oxygen.
