This study investigated the co-combustion of blends coal and biomass residues from poplar sawdust, rice husk, pine nut shells, sunflower for ecofriendly energy production. Proximate ultimate analyses calorific values were also carried out to evaluate properties residues. The volatile matter in was reported as 43.38 wt% ranged 56.76 80.95 analysis carbon sulfur content 68.7 5.5 wt%, respectively...

Coal consumption and carbon dioxide emissions from coal combustion in China are attracting increasing attention worldwide. Between 1990 and 2013, the coal consumption in Shandong Province increased by approximately 5.29 times. Meanwhile, the proportion of coal consumption of Shandong Province to China rose from 7.6% to 10.8%, and to the world, it rose from 1.8% to 5.5%. Identifying the drivers ...

This paper addresses the experimental investigation of coal combustion characteristics (ignition, burnout and NO formation) under oxy-steam conditions. Two coals are selected in order to compare effect rank: bituminous sub-bituminous ones. The experiments have been conducted an electrically-heated entrained flow reactor for a set O2/N2, O2/CO2 O2/H2O/CO2 atmospheres, with O2 concentrations up 3...

Coke corresponds to 2/3–3/4 of the reducing agents in BF, and by partial replacement coking coals with 5–10% bio-coal, fossil CO2 emissions from BF can be lowered ~4–8%. Coking coal blends 5% 10% additions bio-coals (pre-treated biomass) different origins pre-treatment degrees were carbonized at laboratory scale a bio-coal addition technical scale, aiming understand impact on properties (ash am...

The possibility of applying biochar in mild torrefaction treatment to improve the thermochemical characteristics ground biomass was focus study. Camelina straw and switchgrass were torrefied a reactor using microwave irradiation at temperatures 250 °C 300 with residence times 10, 15 20 min, under nitrogen-activated inert conditions. Both addition more than 10% time significantly affected produc...
