In this work the effects of fuel parameters and under grate flue gas recirculation (FGR) are investigated when applying staged air combustion of solid fuel for the purpose of NOx reduction. In addition to temperatures, residence times and primary and overall excess air ratio, the fuel-N content and ...

Low-temperature pyrolysis is one of the most promising methods for lignite upgrading and staged utilization, however, its effect on particulate matter emissions from the combustion of upgrad lignite has not been reported before. In this paper, Xilin Gol lignite was pyrolyzed in a fixed-bed reactor a...

Soot is an important toxic pollutant generated during high-temperature incineration of solid waste (i.e., biomass and plastic waste) under air-lean conditions, and has a great impact on flame radiation. The main objective of this work is to study the synergistic effect of biomass and polyurethane co...

The effect of torrefaction severity (temperature and residence time) was studied on the thermal decomposition of different parts of Norway spruce (stem wood, stump, and bark). The volatile content of the torrefied samples was characterized by pyrolysis–gas chromatography/mass spectrometry (Py–GC/MS)...

The effects of processing conditions (closed versus open reactor, pressure, temperature, soaking time, biomass loading, heating rate, and fuel particle size) on product yields and char properties from constant-volume carbonization are reported. Increasing the pretest, inert-gas, system pressure from...
