Issue 15/2013 - Breakthrough in PVC-containing waste incineration technology

A breakthrough has been made in PVC-containing waste incineration technology

The elimination of dioxins, highly toxic substances produced during waste incineration, is a recognized worldwide problem
.
Recently, Yichun Practical Technology Research Institute announced that they have completed the research of new process technology for smokeless waste incineration, and built a set of 1,000-ton garbage smokeless incineration device
.
The device treats and tests the chemical waste with PVC (the main substance that produces dioxins) as the main component, and obtains satisfactory results, and can successfully realize smokeless incineration of waste with water, and can also use waste heat to generate electricity
.

When using this technology to incinerate low-calorific value water-carrying waste, there is no need to add any chemicals and fossil fuels to the garbage, nor to inject liquefied gas or natural gas into the waste incineration flue gas twice, and the flue gas produced does not require post-treatment processes
such as activated carbon adsorption and bag filtration 。 The monitoring data of the Analysis and Testing Center of the Shanghai Advanced Research Institute of the Chinese Academy of Sciences shows that the combustion efficiency of the device is 97.
6%, the content of dioxins in the flue gas is 0.
039mg/m3, nitrogen oxides (NOx) 146mg/m3, and carbon monoxide (CO) 22mg/m3, which are much lower than the current national standards for waste incineration and the limit values of EU standards, and no sulfur dioxide (SO2) or hydrogen chloride (HCl)
are detected in the flue gas.
