One, the structure and size of the incinerator should be based on the type of garbage, nature, calorific value, combustion rate and other factors reasonably determined to ensure that the garbage in the furnace chamber has sufficient temperature and residence time, increase the garbage and the opportunity to contact with the oxygen, control the flow rate of the air and combustion gases and flow, so that the gas can be evenly mixed.
Two, the incinerator feeding system should be used automatic feeding device to maintain the sealing of the furnace to prevent the escape of harmful gases. Garbage should be pre-treated before feeding, such as matching, mixing, crushing, dehydration, etc., so that the garbage is mixed evenly, conducive to the incinerator stable, safe and efficient operation.
Three, the incinerator's auxiliary fuel system should be able to meet the ignition start and stop the furnace requirements, and can be in the garbage calorific value of low combustion. Auxiliary fuel selection should be determined according to local fuel sources. The position and angle of the auxiliary fuel nozzle should be reasonably arranged to avoid direct flame impingement on the refractory material or cold waste gas stream.
Four, incinerator refractory materials should be able to withstand high temperatures and corrosion, the quality should meet the appropriate technical standards. Refractory material selection should be based on different parts of the temperature and corrosion to determine. Refractory materials should be used as a whole, tight material, such as refractory concrete, refractory plastic, etc., to reduce the gas phenomenon. Refractory support frame, anchors and steel shell steel plate material should also have good heat resistance and corrosion resistance.
Fifth, the incinerator exhaust system should be used frequency control device to ensure that the incineration process of negative pressure. Incineration plant is appropriate to consider the heat produced by the appropriate form of utilization, such as the production of saturated steam or hot water. Utilization of thermal energy generated by the incinerator, care should be taken to prevent the boiler from high and low temperature corrosion, and avoid the 200 ~ 600 ℃ temperature range.
Sixth, the incinerator emission system should use effective purification technology to remove acidic pollutants, dioxins, nitrogen oxides, heavy metals and other hazardous substances, and in line with relevant state regulations.
