coal-fired boiler exhaust step

How Does That Work: Coal-fired power plant - OPPD The Wire

Aug 10 2015 · The exhaust or spent steam passes over a series of tubes through which cool water from the Missouri River flows. The steam condenses back to water and returns to the boiler. It heats up again before going through the cycle. A closed circuit confines the river water which is used only for cooling.

Coal Fired Boiler Emissions Test - EPA

Jun 15 1994 · 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 through a stack.

How Stuff Works: How coal-fired power plants work ...

Nov 13 2010 · The first step in turning the coal into electricity is a pulverizer. The coal turns into a powder that will make it easier to burn cleanly. The coal powder enters a boiler on a stream of air. In the boiler the coal burns and in the process heats a set of tubes filled with water. The water flashes into steam at 1000 degrees F and 3500 PSI.

Measurement of O2 Concentration in Exhaust Gases from ...

In a pulverized coal-fired boiler of a large power plant an oxygen analyzer is essential for combustion control. Exhaust gases from the pulverized coal boiler contain a large quantity of dust and flow very fast. Oxygen analyzers that employ a sampling method may be subject to wear or clogging resulting in increased maintenance workload and cost.

Coal-Fired Boiler - an overview | ScienceDirect Topics

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective two phase mixtures of water and steam are replaced by a single supercritical fluid when the pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C ( Shen and Cheng 2004 ).

Estimates of particle formation and growth in coal-fired ...

A pre-existing model of plume particles is examined to determine its usefulness for simulating particle formation and growth in coal-fired cyclone boiler exhaust. Of greatest interest are fine particles (diameters of 0.2-2 m) most likely to influence plume opacity. For the examined these particles consist primarily of water-sulfuric acid droplets formed from emitted SO 3.
