The oxygen in the incinerator is used to support the combustion process of the waste. During incineration, waste needs to undergo a chemical reaction with oxygen to release energy and convert it into ash. Therefore, the oxygen in the waste incinerator plays a role in promoting the combustion of waste. At the same time, oxygen can also help burn out harmful substances in garbage, thereby reducing environmental pollution. However, too much oxygen will cause the combustion process of garbage to be too violent, generating too much heat and exhaust gases, and increasing the risk of environmental pollution. Therefore, the oxygen in the waste incinerator needs to be controlled in the appropriate proportion.
