Urban household waste consists of two main parts: combustible and non combustible waste. The combustible part includes waste paper, rags, bamboo, leather, plastic, and animal and plant residues. The non combustible parts include various types of waste metals, sand, glass ceramic fragments, etc. The consumption level in Chinese cities is relatively low, the proportion of non combustible components in garbage is high, and the calorific value is much lower than in developed countries. However, the living standards in Chinese cities are constantly improving, and urban garbage is developing towards a trend of decreasing moisture content and gradually increasing combustible components. The calorific value of garbage in medium-sized and above cities is generally between 2512-4605 kJ/kg, and in some areas it has reached 3349-6280 kJ/kg, which meets or is close to the requirements of garbage incineration (calorific value not less than 3350 kJ/kg).
It should be noted that the proportion of non combustible components in urban waste in China is high, with low calorific value and high moisture content. Moreover, the composition of waste varies depending on the region, season, urban consumption level, and year. Therefore, it is required toRefuse incineratorIt has strong adaptability to changes in the composition of garbage, especially changes in moisture and calorific value, and can adjust the combustion process in a timely and effective manner based on fluctuations in garbage composition to ensure timely ignition and stable combustion of garbage. Since Shenzhen adopted the Japanese waste incineration system in 1985, cities such as Zhuhai and Guangzhou in China have also adopted foreign waste layer combustion incineration systems. The Shanghai Pudong New Area household waste incineration plant will also introduce inclined reciprocating grate incinerators provided by French companies. We should introduce foreign equipment, accumulate operational experience, gradually digest foreign technology, and then develop and research waste incineration equipment that is suitable for China's actual situation.
