Pulverized coal combustion characteristics of high-fuel-ratio coals

Hydrogen sulfide formation characteristics of pulverized coal combustion – Evaluation of blended combustion of two bituminous coals

“…1 shows a schematic diagram of the pulverized coal combustion test furnace. We have been operating the furnace for more than 30 years, and have fired various types of solid fuels including bituminous coals, sub-bituminous coals, high-fuel-ratio coals, high-ash coals and biomass fuels under a wide range of combustion conditions [10][11][12][13][14][15][16]. We confirmed that the peak temperature and the contents of the exhaust gas such as the NOx, are almost the same as those of Japanese power stations.…”

Numerical Simulations of Pulverized Coal Combustion

“…The details of the governing equations, mathematical models and numerical procedures for RANS simulations of pulverized coal combustion are described in our previous papers [12][13][14][15][16][17] .…”

“…Although the figure is omitted here, it was found that the prediction of the NOx concentration is improved compared to the simplified-shape case 15) and that present numerical method can capture the general combustion characteristics of high-fuel-ratio coals 16) .…”

Study on combustion characteristics of coal-biomass for co-firing system as a feedstock of coal gasification process

“…According to Kurose et al (2004), the lower the fuel ratio, the harder the coal to be burned. In contrast, the higher the fuel ratio, the easier the fuel to be burned.…”
