Today we will briefly introduce to you the knowledge about garbage incinerators, and hope that you can count them into the working state. From the perspective of investment and operation economy of incinerators, the minimum incineration capacity should be 3 t/h to 20~25t/h. Therefore, modern small waste incinerator incineration systems should meet the following requirements:
The furnace fire has a strong effect, which ensures the uniform and full combustion of garbage on the grate surface and prevents slag formation, and the main factors affecting the combustion of the grate are:
(1) The type of grate, the mode and intensity of the grate movement, the inclination angle of the grate, and the direction of the garbage movement on the surface of the grate. In order to ensure the timely ignition, burning and burning of garbage, the grate should be divided into three drying zones and ignition zones, the main incineration zone and the ash zone.
(2) The combustion equipment should be able to adapt to the sudden fluctuation of waste composition (water or calorific value), and when the waste composition fluctuates, timely and accurately adjust the feed volume, primary air volume and its distribution and temperature of the incinerator.
(3) Preheating the combustion air (primary air and secondary air);
(4) the possibility of adding some additives to reduce the emission of certain harmful substances such as dioxins, NOx and SOx;
(5) the whole combustion process is divided into the garbage incineration stage and the combustion stage of combustible harmful substances in the flue gas, and enough air is required in the later stage of the flue gas embers, and the amount of combustion air is limited in the garbage incineration stage. Avoid drastic fluctuations in furnace temperature and excessive fly ash.
(6) Ensure low ash and fly ash carbon content (1~3%), and burn well.
