Abstract

The invention discloses a method for fire grate control for a fire grate type garbage incinerator. The method comprises the following steps: receiving the combustion state of the incinerator or the operator command according to the control state of a fire grate, and calculating the latency time of the fire grate returned to the position; according to the preset rule, outputting a starting or stopping command of the fire grate according to the total guard command of a boiler, the operator input order, the position signal of the fire grate and the latency time of the fire grate returned to the position; determining whether the synchronous command is output or not according to the operator command; outputting an advancing or retreating command of the fire grate according to the operator inputorder, the synchronous command and the position signal of the fire grate; and performing logical operation to the starting or the stopping command of the fire grate and the advancing or retreating command of the fire grate to obtain an action command of the fire grate, and then outputting the action command to a fire grate hydraulic system. The invention also discloses a fire grate control devicefor the fire grate type garbage incinerator. By adopting the embodiment of the invention, the automatic control of combustion of the garbage incinerator is realized, and the purposes of rapidness, stability, reliability and security are achieved.

Description

technical field [0001] The invention relates to the field of grate control, in particular to a grate control method and device for a grate type garbage incinerator. Background technique [0002] With the development of the economy, the continuous increase of the population, and the improvement of people's living standards, the amount of urban waste generated is also increasing. At the same time, the calorific value of waste continues to increase, which provides the possibility for resource utilization of urban domestic waste. [0003] Utilizing municipal solid waste for power generation and heating has achieved the goals of urban solid waste reduction, harmlessness and resource utilization, and has achieved high social and economic value. It is one of the ideal methods to solve the problem of municipal solid waste. [0004] The grate-type waste incinerator has the advantages of low operating cost, large waste shrinkage ratio, and no need for pretreatment equipment. It is cur...
