Mar 15, 2021Coal-fired industrial boilers (CFIBs), the major energy conversion devices and stationary combustion emission sources in China, consumed about 700 million tons of coal accounting for 13.5% of the total coal consumption in China in 2015 (NBS, 2016; Yue et al., 2018). CFIBs release large quantities of air pollutants.

Exergy loss is dominated by destruction due to irreversibility in coal combustion and heat transfer. Average energy efficiency and CO 2 emission of 141 boilers were estimated to be 76.08% and 147.13 kg-CO 2 /GJ, respectively. Exergy efficiencies of typical samples were estimated at about 12.88% for hot water boiler and 27.97% for steam boiler.

Just as coal-fired boilers are not designed in the same way as oil- or gas-fired boilers, neither can biomass-fired boilers be designed as coal-fired boilers, if they are to function efficiently. Biomass firing requires a larger furnace (i.e. a larger radiation heat transfer surface) than coal firing.

Jun 23, 2021However, it leads to the rise of the exhaust gas temperature and the decrease of the boiler efficiency, which can be ascribed to the large amount of the cold primary air sent into the pulverizing system to control the air pulverized coal flow temperature at the mill outlet. The ignition distances of three experimental coals are different.
