Incineration is a method of placing waste in a high temperature furnace to fully oxidize its combustible components, generating heat for power generation and heating.Westinghouse and o 'connor have developed a successful waste-to-energy system.The incinerator of this system can turn the garbage with humidity up to 7% into dry solid for incineration, and the incineration efficiency reaches over 95%. Meanwhile, the high temperature on the surface of the incinerator can convert heat energy into steam, which can be used for heating, air conditioning equipment and steam turbine power generation.
The company introduces advanced waste incineration technology from abroad, and the common household garbage, slaughtering garbage and special garbage of hospitals and other units in the research and development of waste incinerators are harmless treated. The residual ash generated in the incineration process accounts for about 5% of the weight of biological waste before incineration, which is generally high quality phosphate fertilizer.In recent years, more and more attention has been paid to the renewable energy technology of waste incineration.
The advantages of incineration treatment are good reduction effect (incineration residue volume reduced by more than 90%, weight reduced by more than 80%), and thorough treatment.But incinerators are expensive to build and produce, according to reports in the United States.In most cases, the electricity generated by these devices is worth far less than expected sales, leaving local governments with huge economic losses.Because garbage contains some metals, incineration is highly toxic and produces secondary environmental hazards.Incineration requires the calorific value of waste to be greater than 3.35mj /kg, otherwise, combustion accelerant must be added, which will increase the operating cost to the general city can not afford.
