從不同的角度有很多種分類方法。按爐型分類可分為 固定爐排爐、機械爐排爐、流化床焚燒爐(主要用來處理工業(yè)垃圾)、回轉窯爐等。為增強生活垃圾焚燒的效果，經常在焚燒中應用熱分解和氣化(熔融)技術。利用焚燒爐進行無害化處理的操作步驟：
1、注入燃料，接通電源，啟動助燃開關，爐內溫度達到自燃溫度，將病害畜禽肉尸及其產品投入爐內，關閉助燃開關，啟動自燃開關，病害肉體保持自燃狀態(tài)不能剖割的病害畜禽尸體整體投入焚燒爐中，啟動自燃開關，尸體自燃至*碳化為止。
2、整尸焚毀：不能剖割的病害畜禽尸體整體投入焚燒爐中，啟動自燃開關，尸體自燃至*碳化為止。
3、肉尸分割焚毀：允許分割的病害肉品分割后投入焚燒爐中，啟動自燃開關，肉塊自燃至*碳化為止。
4、臟器焚毀：病害畜禽臟器整體投入焚燒爐中，啟動助燃開關，使臟器在助燃狀態(tài)下燃燒至*碳化為止。
5、焚燒后的碳化物需要選擇地點（遠離水源地和居民區(qū)）進行掩埋，杜絕病菌的傳播。
There are many classification methods from different angles. According to the classification of incinerator, it can be divided into single chamber incinerator and multi chamber incinerator. According to the relationship between flue gas and garbage moving direction, the furnace can be divided into three types: forward flow, counter flow, AC and secondary flow.
Incinerator is a kind of harmless treatment equipment commonly used in medical and domestic waste and animal harmless treatment. The principle is to use coal, fuel oil, gas and other fuels to burn and carbonize the objects to be treated, so as to achieve the purpose of disinfection.
There are many classification methods from different angles. According to the furnace type, it can be divided into fixed grate furnace, mechanical grate furnace, fluidized bed incinerator (mainly used to treat industrial waste), rotary kiln, etc. In order to enhance the effect of MSW incineration, thermal decomposition and gasification (melting) technology are often used in incineration.
Operation steps of harmless treatment with incinerator:
1. When the temperature of the body burning furnace is turned on, the whole body burning auxiliary switch is turned on, and the temperature of the meat burning furnace can not be kept when the temperature of the meat burning furnace is turned on.
2. Burn the whole corpse: the diseased livestock and poultry corpses that can not be cut are put into the incinerator as a whole, and the spontaneous combustion switch is activated, and the corpse will ignite until it is completely carbonized.
3. Segmentation and burning of meat carcass: the diseased meat products are allowed to be put into the incinerator after being cut, and the spontaneous combustion switch is started, and the meat pieces will ignite until they are completely carbonized.
4. Organ burning: the diseased livestock and poultry organs are put into the incinerator as a whole, and the combustion supporting switch is started to make the organs burn in the combustion supporting state until they are completely carbonized.
5. The burned carbides need to be buried in places far away from water sources and residential areas to prevent the spread of pathogens.
