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.
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.
The coal water slurry will also add fuel diversity to the generation fleet which is currently weighted at around 70% natural gas fuel. Coal water slurry may become a key technology for Thailand to help achieve the recently announced goal of a 40% fuel mix for coal set by the Government policy (before about 20%).
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

Combustion of standard fossil fuels (natural gas and ASTM Grade Oil) in commercial and industrial boilers results in the following nine emissions; carbon dioxide, nitrogen, oxygen, water, carbon monoxide, nitrogen oxide, sulfur oxides, volatile organic compounds, and particulate matter.
It is worth noting that the combustion of coal-water slurries requires some modification (or, at least, readjustment) of the automatic fuel equipment of boiler units, raising the importance of fuel composition gasification (Egorov and Strizhak, 2017, Ma et al., 2016, Zhang et al., 2017a) as an intermediate step of fuel preparation.
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.
The Pennsylvania State University is conducting a coal-water slurry fuel (CWSF) program with the US Department of Energy (DOE) and the Commonwealth of Pennsylvania to determine the viability of firing CWSF in an industrial boiler designed for heavy fuel oil. Penn State and DOE have entered into a cooperative agreement to determine if CWSFs prepared from cleaned coal (containing approximately 3
More coal processing is done in foreign coal-producing countries because of their requirements for a smokeless fuel, their need to make a satisfactory metallurgical coke from inferior quality coals, and their general lack of indigenous oil or gas from which to produce chemicals or other carbon-based products.

In steam power plants, the thermal energy contained in water vapour is used to power a steam turbine which in turn drives the generator. In the process, conventional fuels such as oil, natural gas, hard coal or brown coal are used to fire the steam boiler. In coal-fired power plants, coal is the only fuel used, whereas waste incineration

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.

In a cyclone furnace, where crushed coal is used as a fuel, 70 to 80 percent of the ash is retained as boiler slag and only 20 to 30 percent leaves the furnace as dry ash in the flue gas. (2) A general flow diagram of fly ash production in a dry-bottom coal-fired utility boiler operation is presented in Figure 1.
While stack draft may be an important measurement, fuel oil and gas fired power burners require draft control over the fire to maintain a proper and controlled intake of combustion air. Comparing stack and overfire O 2 can verify that leakage between boiler sections, access door, etc is minimal and the combustion test results are accurate.
