The U.S. Army has been tasked to reduce its dependence on and consumption of petroleum fuels. Coal water slurry fuel (CWSF) is considered a feasible alternative to the heavy fuel oil currently used as a boiler fuel. At the core of CWSF technology is the burner, which is a hybrid between a pulverized coal burner and a No. 6 fuel oil burner.

Converting a boiler to natural gas typically decreases boiler efficiency because of the large quantity of hydrogen in natural gas. During combustion, the hydrogen is converted to water.
Entropy tested the exhaust gases from the Unit 1 coal-fired boiler. The furnace burns bituminous coal. Gases from the combustion furnace pass through two electrostatic precipitators (ESPs) to control particulate. Gases exiting the ESPs pass through a flue gas desulfurization unit (FGD), to remove SO2, and are then exhausted through a stack.

Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas". Coal gas is combustible and

air leakage into the furnace or boiler; underfiring in the combustion chamber; When the CO 2 content of the flue gas is too high it is common with excess smoke in the flue gas. High carbon dioxide content may be caused by. insufficient draft; overfired burner; Smoke (only fuel oil burners) Smoke in flue gas indicates poor burner performance.
Fossil fuel:Ancient organic remains (fossils) in sediments which over eons became sedimentary rock, giving rise to solid, liquid and gaseous fuels such as coal, crude oil, and natural gas. Coal is derived from vegetable matter altered by pressure, whereas crude oil and natural gas are derived from animal and vegetable matter altered by pressure

Abstract. This is the third of three volumes describing a multi-phase, coal-water slurry (CWS) test program. This volume summarizes the results of tests of a single, full-scale 15-million Btu/hr burner to be used in a multi-burner industrial boiler demonstration of CWS at a DuPont plant in Memphis, Tennessee.
Coal-liquid mixtures or slurries—primarily coal-oil and coal-water fuels—are another commercial technology that allows coal to be substituted for liquid fuels in combustion applications. R&D in this area peaked during the late 1970s and early 1980s when oil prices were high and coal-based substitutes were attractive.
