The combustible garbage which is easy to ignite is selected to be added into the gasification chamber, and the drying chamber is filled with the combustible garbage (both dry and wet). And starting the gas igniter, igniting the combustible garbage in the gasification chamber, and closing the gas igniter after igniting. And (3) starting cooling water circulation equipment to circulate cooling water in the outer wall of the furnace body, and cooling the outer wall of the furnace body to keep the temperature of the outer wall of the furnace body below fifty ℃. And the electronic igniter in the combustion chamber is started timely, so that deflagration caused by ignition when the combustible gas is excessively accumulated is prevented, and the electronic igniter is closed until the temperature in the combustion chamber reaches more than one hundred ℃ in thousand.
After the combustible garbage in the gasification chamber is ignited, the combustible garbage is combusted in a low-oxygen state, and in the low-oxygen combustion process, the temperature of the gasification chamber and the combustion chamber is gradually increased until the temperature reaches more than eight hundred ℃, and a large amount of combustible mixed gas, mainly carbon monoxide, methane, smog, coal tar and the like, is generated. A part of the combustible and non-combustible mixed gas rises through a main cavity of the gasifier in the main body part of the pagoda-shaped gasifier and directly enters the inner cavity of the burner, and the other part of the combustible and non-combustible mixed gas enters a gasification channel in the main body part of the gasification chamber through a gasification channel of the auxiliary part of the gasifier and then enters the inner cavity of the burner.
