“…The release has little effect at low temperature, but it aggravates the release of HCl during combustion at medium-high temperature. At the same time, mixed burning of municipal solid waste will show a higher HCl release [16][17][18][19][20]. Municipal solid waste incineration will release a large number of HCl pollutant gas, not only will corrode the metal pipe wall, shorten the service life of the equipment, at the same time, in the presence of carbon sources will produce dioxin precursors, which seriously harm to life and ecological environment [21,22].…”

The incineration treatment of municipal solid waste is widely used, but gas-phase hydrogen chloride (HCl) generated during the incineration seriously threatens the heating surface of boiler tail, and even causes serious harm to environment. Through incineration experiments, this paper found that many factors (temperature, oxygen concentration, residence time and moisture content) affect the HCl emission characteristics in the process of municipal solid waste incineration treatment. In order to effectively cut back the HCl emission in incineration treatment of municipal solid waste, this paper proposes torrefaction and classification pretreatment of municipal solid waste. Torrefaction pretreatment has a significant inhibitory effect on HCl emission during the incineration of mixed municipal solid waste. At the same time, compared with the incineration treatment of mixed municipal solid waste, sawdust and plastic municipal solid waste of the same quality after classification pretreatment can effectively curb HCl emissions within the entire temperature range. In particular, HCl emissions are reduced by 35% during sawdust incineration treatment at 400°C. Furthermore, by studying the reaction mechanics of HCl generation during combustion at different temperatures, and the reaction rate of HCl generation is: mixed municipal solid waste >plastic >sawdust. Therefore, this paper believes that torrefaction and classification pretreatment of mixed municipal solid waste is beneficial to inhibit the precipitation of chlorine during the incineration process and promotes the resource utilization of municipal solid waste, which is of significant significance for energy conservation and emission reduction.

The effect of hydrogen charging on the corrosion behavior of E690 steel in 3.5 wt.% NaCl solution was investigated. The corrosion behaviors of the charged and uncharged steel were characterized using scanning electron microscopy, x-ray diffraction, Raman spectroscopy and x-ray photoelectron spectroscopy. The results showed that hydrogen charging promoted the precipitation of corrosion products on the surface of E690 steel, with the corrosion products mainly consisting of a-Fe 2 O 3 , a-FeOOH and c-FeOOH. The relative content of a-FeOOH reached maximum when the hydrogen charging current density was 20 mA/ cm 2 , and two different corrosion product layers were formed on the surface. And the hydrogen charged current density at 20 and 50 mA/cm 2 , the potentiodynamic polarization curves also displayed passivation regions.
