The ESP of the city of Hamilton, OH Municipal Electric Plant

Boiler MACT Compliance

The city of Hamilton, OH Municipal Electric Plant (Hamilton), operates a pulverized coal fired boiler (No. 8) subject to the boiler Maximum Achievable Control Technology (MACT) standards issued by the US EPA. EQ Engineers, LLC (EQE) has been employed by Hamilton to study and evaluate options for achieving MACT standards on a consistent basis as ...

FGD Inlet Ductwork

R.M Schahfer Units 17 & 18 are Combustion Engineering (CE) tangential firing PC boilers with net full load output of 361 MW. They currently burn Illinois bituminous fuel and are equipped with limestone wet flue gas desulfurization (FGD) systems for SO2 control. The flue gas will come into contact with limestone slurry in the absorber ...

Power Plant FGD Training Model

NIPSCO has two new Flue Gas Desulfurization (FGD) systems at its Schahfer Generating Station. The FGD systems are designed to remove SO2 from flue gas generated by the boiler. The flue gas enters the absorber just above the reaction tank liquid level and rises upwards. As it rises, it contacts fine droplets of recycled ...

Venturi Scrubber

A venturi scrubber is a device which utilizes liquid to remove fine particulates from gaseous streams. ArcelorMittal USA has developed a pollution control process using venturi scrubber for removal of particulates from the exhaust gas in a sinter plant. However, excessive wear on the side wall of the throat has been found leading to considerable ...

Virtual Groundwater

Groundwater, as the major contributor to the fresh water resource, has been contaminated by agricultural and industrial activities in recent years. However, it is extremely difficult to obtain data to assess the current pollution situation or to predict contaminates’ movement trend. The problem also renders challenges in education. Civil Engineering Students are easy to get ...

Wind Energy

The issue of transferring learned concepts to practical applications is a widespread problem in postsecondary education. Related to this issue is a critical demand to educate and train a generation of professionals for the wind energy industry. With initiatives such as the U.S. Department of Energy’s “20% Wind Energy by 2030” outlining an exponential increase ...

Wind Flow Simulations

Wind energy, as one of the cleanest renewable energy, is becoming increasingly important. Both the installed wind power and the generated energy are increasing by 30% per year world-wide. Economical performance of a wind turbine is determined by the efficiency of the blade. If the airflow over wind turbine blades could be controlled fully, the ...

Wind Turbine Control Systems Simulator

A lack of trained wind energy professionals exist qualified to develop and maintain the increasing number of wind turbines across the country. Further, effective training of new technicians is obstructed by a disconnect between theoretical learning in the classroom and practice in the real world. Finally, access to “hands-on” training with actual wind turbine equipment ...
