A method and system for automatic control of garbage furnace incineration with load correction

Abstract

The invention discloses an automatic incineration control method for a destructor with a load correction function. The automatic incineration control method for the destructor with the load correction function comprises the steps of judging whether a burnout temperature control deviation overruns; if yes, judging whether the opening degree of an air door reaches an amplitude limit state; if yes, obtaining the cumulative time during which the burnout temperature control deviation overruns and the opening degree of the air door reaches the amplitude limit state; and judging whether the cumulative time reaches a correction period, and if yes, correcting the load output through correcting a push material increment. Stable control over a fire grate boiler system is achieved through load correction, it is guaranteed that the garbage handling capacity of the system is reasonably used, sufficient burning of garbage is guaranteed at the same time, and requirements of pollution discharge indexes are met. The invention further discloses an automatic incineration control system for the destructor with the load correction function.

Description

technical field [0001] The invention relates to the technical field of garbage incineration treatment, in particular to an automatic control method and system for garbage furnace incineration with load correction. Background technique [0002] Municipal solid waste incineration power generation is currently one of the most popular and effective waste disposal methods in the world. After nearly 130 years of development, this technology has matured and been widely used. It is also the most suitable for my country's national conditions. A method of garbage disposal. The reciprocating mechanical grate domestic waste incineration boiler has the advantages of strong adaptability to waste treatment, large waste treatment capacity of a single unit, and easy control and adjustment. It has become the main equipment of incinerators in my country. [0003] At present, the existing garbage furnace control system has great shortcomings in adapting to the large variation of the calorific v...

AI Technical Summary

Problems solved by technology

When the calorific value of waste changes, in order to quickly respond to load requirements, after the waste treatment volume is adjusted in the burnout section, there is no closed-loop correction link, and it is often easy to occur in the burnout section or the temperature is too high, and the waste treatment capacity of the system is seriously idle. The grate is prone to dry burning; or the temperature is too low, and the waste system processing capacity of the current calorific value has reached the upper limit, and it is very easy to burn insufficiently

As a result, the entire control system cannot adapt to system waste and load changes, and cannot continue to operate well online
