2.1. Water Usage in Coal to Power Applications | netl.doe.gov

Schematic of a wet recirculating cooling water system for a 520-MW Coal-Fired Boiler. In dry cooling systems the steam exhausted from the turbine is cooled by forcing ambient air across a heat exchanger filled with the condensing steam. There is no loss of water to evaporation or blowdown in this configuration and therefore both water

How Does a Coal Power Plant Work? - Bright Hub Engineering

Dec 04, 2008 · Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2. The second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam. In modern power plant, boilers produce steam at a high pressure and

Challenges when Converting Coal-Fired Boilers to Natural Gas

The system designer should investigate these questions, as there are inherent tradeoffs between flexibility and system cost. Riley Power recently participated in field testing on a wall fired boiler rated at 1,779,000 lb/hr of main steam flow. The boiler is an opposed fired design with two (2) levels of burners on both the front and rear walls.

Pulverized coal-fired boilers. This is an example of application to exhaust gas processing from a pulverized coal-fired boiler. We reduced the size of the fabric filter by increasing the filter bag length to 9 m (normal length is 6.0 m or 6.9 m). Using a long filter bag for a large quantity of process gas made it possible to reduce the size of

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 boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).
