Combustion control in waste incinerators is a complex and critical process designed to ensure stable combustion of waste while meeting the requirements of environmental protection and economic benefits. Here are some key introductions to waste incinerator combustion control:
1.Automatic control of the combustion process: Through the computer control system, the precise control of the grate movement can be realized, so as to regulate the combustion process of the garbage. The movement of the grate can make the garbage more likely to catch fire and prolong the time the garbage stays on the hearth, for example, by pushing it backwards. In addition, the computer control system can also issue instructions to control the combustion of the incinerator according to the temperature value of the furnace temperature measurement point to meet the environmental protection requirements of seconds.
2.Automatic combustion control system: This system is designed and researched for the problems existing in the manual ignition operation process in the traditional combustion mode. It mainly includes evaporation control module, garbage layer control module, incinerator furnace temperature control module, slag hot burn rate control module, oxygen control module, etc. The automatic combustion control of the waste incinerator is realized through the calculation of parameters such as feeding speed, grate speed, combustion air volume and garbage layer thickness. This control system can effectively improve the reliability and safety of incineration and power generation, and achieve product quality and economic benefits.
3.Waste incineration process: The garbage is first transported to the garbage storage pit, where it is usually stored for 5 7 days for fermentation to reduce the water content and improve the incineration effect. The garbage is then sent to the hopper of the incinerator by means of a garbage crane. In the incinerator, the waste goes through three stages: drying, combustion, and ember burning. The slag after burning is cooled by the slag extractor and discharged to the slag pit for storage, which can be used as a building material for comprehensive utilization. The flue gas generated by waste incineration is exchanged for heat through the waste heat boiler, and then the harmful gas is removed through the tail gas treatment system, and then discharged into the atmosphere after reaching the standard.
In general, the combustion control of waste incinerator is a complex and critical process, which requires a comprehensive consideration of a variety of factors, such as furnace temperature, feeding rate, grate speed, combustion air volume, etc. Through the use of advanced computer control system and automatic combustion control system, the precise control of the waste incineration process can be realized, so as to improve the incineration efficiency, reduce pollution emissions, and realize resource utilization.
