Background
The method for generating power by incinerating renewable resources is to incinerate resources such as garbage with high combustion value at high temperature (pathogenic organisms and corrosive organic substances are thoroughly eliminated). The heat energy generated in the high-temperature incineration (the generated smoke is treated) is converted into high-temperature steam to drive a turbine to rotate, so that a generator generates electric energy. The process is commonly used in incinerator plants, wherein the working principle of the pulse-throw incinerator is as follows: the renewable resources are sent to a drying bed of the incinerator for drying through the automatic feeding unit, then sent to a first-stage grate, subjected to high-temperature volatilization and cracking on the grate, thrown under the pushing of the air power device, and thrown into a next-stage grate step by step, and at the moment, high molecular substances are cracked and other substances are combusted. And then the slag enters the ash pit and is discharged by the automatic slag removing device after being burnt out. The combustion-supporting air is sprayed from the air holes on the grate and mixed with the garbage for combustion, and the garbage is suspended in the air at the same time. The volatilized and cracked substances enter the second-stage combustion chamber for further cracking and combustion, and the unburned flue gas enters the third-stage combustion chamber for complete combustion; the high-temperature flue gas heats steam through the heating surface of the boiler, and simultaneously the flue gas is discharged after being cooled.
The renewable resources may not be uniformly distributed on each stage of grate, so that the condition that some grates need to be supplied with air and some grates do not need to be supplied with air may occur. However, the air holes of the incinerator are all communicated with the same air supply chamber or are divided into a plurality of groups to be communicated with a plurality of air supply chambers, and the air supply chambers supply air by the same fan, so that the pulse air supplied by all the air holes or adjacent multi-stage air holes is synchronous, and the incinerator cannot supply air to a specific certain stage of grate according to the condition of renewable resource combustion. This is disadvantageous for sufficient and uniform combustion of the regenerated resources. According to the existing incinerator structure, an air supply chamber and a fan cannot be arranged for each grade of grate, otherwise, the structure of the incinerator is very complicated, and cost control is not facilitated.
