Abstract

The invention relates to a method for controlling an air supply system of a water-cooling reciprocating multistage hydraulic mechanical grate furnace. The grate furnace comprises a feed fire grate, an incineration fire grate, a primary air supply system and a secondary air supply system, and the incineration fire grate consists of a plurality of sliding fire grate segments and fixed fire grate segments which are provided with water-cooling pipes for cooling the fire grate segments. The method comprises the step of adjusting a primary air volume according to the temperature of flue gas at an outlet of a combustion chamber. The combustion condition of volatiles can be obviously improved through adjusting secondary air according to the temperature and oxygen content of the flue gas at the outlet of a hearth, so that the emission of CO and other pollutants is reduced.

Description

technical field [0001] The invention relates to the field of incinerators, in particular, the invention relates to a method for controlling the air supply system of a water-cooled reciprocating multi-stage hydraulic-mechanical grate furnace. Background technique [0002] Waste incineration is one of the main ways to realize waste reduction, harmless and resourceful treatment. At present, garbage incineration has gradually become the main way of garbage disposal. After modern incineration, the volume of garbage can generally be reduced by 80%-90%. At the same time, various pathogens can be eliminated, harmful substances can be converted into harmless substances, and resources can also be realized. use. Due to the different types of waste, it can be divided into domestic waste, high calorific value domestic waste, industrial waste, and medical waste. In the process of incinerating waste, the water content of each type of waste and the calorific value produced after incinerati...
