"kitchen waste" refers primarily to perishable, readily biodegradable waste produced during food processing and dietary consumption. From the chemical composition, the starch, cellulose, protein, lipid, inorganic salt and the like are mainly used. The characteristics of the food waste are as follows: (1) the food-trash has a low calorific value. The calorific value is also called calorific value, which means the heat released after 1Kg of garbage is completely combusted, and people usually use the calorific value to measure or represent the value and the capacity of the garbage as fuel. The low calorific value of the unit mass of the food waste is about 2100-3100 kJ/kg (when the average low calorific value of the food waste is higher than 3349 kJ/kg, no combustion improver is added in the burning process, and when the average low calorific value of the food waste is higher than 4180 kJ/kg, waste heat utilization such as power generation can be carried out), so that combustion supporting of fuel oil or coal and the like is required, the cost is increased, and meanwhile, the temperature is controlled to prevent harmful substances such as dust, dioxin and the like from being generated. (2) High in nutrient elements and can be recycled.
