Problems solved by technology
Domestic waste comes from all aspects of urban life, and there are differences in the storage and fermentation time in garbage pits, resulting in unstable calorific value of fuel for domestic waste incineration
The instability of the calorific value of domestic waste causes unstable heat input at the front end of the waste incineration device, which eventually leads to unstable combustion of domestic waste incineration and unsatisfactory combustion conditions, such as excessive fluctuations in furnace temperature, high slag ignition rate, or Severe fluctuations in flue gas indicators such as CO
The root of the above-mentioned series of problems is the uncertainty of the calorific value of waste, which also leads to the misunderstanding of domestic waste incineration and the related NIMBY effect.

Embodiment Construction
[0051] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0052] like figure 1 As shown, the method for predicting the calorific value of incineration of domestic waste in this embodiment includes steps:
[0053] 1) Obtain the fermentation time of domestic waste, the actual total amount of drainage during the fermentation time period, and the temperature within the preset time period;
[0054] 2) Predict the incineration calorific value of domestic waste according to the fermentation time, actual total drainage volume and temperature.
[0055] The method for predicting the incineration calorific value of domestic waste according to the present invention predicts the incineration calorific value of domestic waste through the fermentation time of domestic waste, the actual total amount of drainage during the fermentation period, and the temperature within the preset time period, which is convenient for...

The invention discloses a household garbage incineration heat value pre-judgment method, a pre-judgment system and an incineration system, belongs to the technical field of garbage incineration, and is used for solving the technical problems of unstable garbage incineration and substandard emission at present. The method comprises the following steps: 1) obtaining the fermentation time of household garbage, the actual total drainage amount of a fermentation time period and the temperature in a preset time period; and 2) predicting the incineration heat value of the household garbage accordingto the fermentation time, the actual total drainage amount and the temperature. The method has the advantages of being easy and convenient to operate, high in pre-judgment precision, stable in incineration, up-to-standard in emission and the like.
Description
technical field [0001] The invention mainly relates to the technical field of garbage incineration, in particular to a method, system and incineration system for predicting the calorific value of incineration of domestic garbage. Background technique [0002] Many cities in China are currently facing the dilemma of being surrounded by garbage. In the process of urbanization, the urban population is increasing day by day, and the increase in urban garbage is relatively large. Domestic waste incineration is currently the most feasible way to solve the urban waste siege, national policies and market development, domestic waste incineration power generation is the future trend. [0003] Compared with traditional coal-fired power plants, the biggest problem facing domestic waste incineration is the uncertainty of fuel. In traditional coal-fired power plants, the source of coal is relatively stable, and at the same time, on-board sampling and measurement can be carried out, and t...
