This work employs large-scale simulations of reactive molecular dynamics to investigate influences of coal char structures, O2 concentration, and temperature on NOx formation during coal char oxidation processes, which are facilitated by combining high-performance computing and cheminformatics-based reaction analysis. The char property models are c...

The reaction of NO with chars of sewage sludge, refuse derived fuel (RDF), and straw was investigated in a fixed bed reactor at temperatures from 800 to 900 degrees C and NO inlet concentrations from 400 to 1500 ppmv. The effect of ash forming elements in the chars was examined by comparing the reactivity of raw and demineralized chars. Compared to...

Emission and distribution characteristics of polycyclic aromatic hydrocarbons (PAHs) were investigated during municipal solid waste (MSW) and coal combustion alone and MSW/coal blend (MSW weight fraction of 25%) co-combustion within a temperature range of 500 degrees C-900 degrees C. The results showed that for all combustion experiments, flue gas ...
Decoupling combustion realized by dividing the coal combustion process into coal pyrolysis and the combustion of volatiles and char can reduce NO emission from coal fired stoves. In this study, decoupling combustion process in coal fired stoves was simulated experimentally with a specially designed dual-bed model reactor. The reactor can simulate v...
The solid phase of the separated raw material was composted and peletized to yield a sellable organic fertilizer. It contained the major part of the organic nitrogen and the phosphate of the raw material. From the liquid phase a liquid fertilizer concentrate was obtained through evaporation making use of the waste heat of the rendering plant. It co...
