In this paper, an online method to calculate coal qualities based on reverse balance thermal efficiency model was integrated into the optimization model. Furthermore, a new constraint was added to the optimization model to meet the demand load. NOx emission characteristics of some 600 MW capacity utility boiler were investigated.

Coal slurry is a mixture of crushed coal and a liquid such as water or oil. The traditional mixture, first patented in England in 1891, consists of 50 percent coal and 50 percent water by weight. Socalled heavy coal slurries or slurry fuels consist of 65 to 75 percent coal, with the remainder being water, methanol, or oil.

In this study, coal fly ash was functionalized, using a simple onestep process (loading with Al3+ and sulfonation), to yield a solid acid catalyst (S/AlCFA) with strong acid sites. The catalyst was then used to produce furfural from xylose in a biphasic system (H2O(NaCl)/tetrahydrofuran). The furfural yield reached 82% at 180 °C60 min with catalyst/xylose ratio of : (w/w).

Everything changed during the Industrial Revolution, which began around 1750. People found an extra source of energy with an incredible capacity for work. That source was fossil fuels — coal, oil, and natural gas, though coal led the way — formed underground from the remains of plants and animals from much earlier geologic times.
