Pulverized Coal Fired Boiler Startup Procedure

However, each CGS coal-fired unit has experienced an average of 1760 starts, including 523 cold starts throughout its lifetime. The overarching effect of this type of cycling is thermal fatigue. For example, large temperature swings from cold feedwater entering the boiler on start-up and from steam as it is heating create fluctuating

Pulverised Coal Combustion With Higher Efficiency ...

Producing electricity in coal power plants can take place in a number of ways with varying degrees of efficiency. In conventional coal-fired plants coal is first pulverised into a fine powder and then combusted at temperatures of between 1300 and 1700 o C. This process heats water in tubes in the boiler so that it becomes steam at a pressure of around 180 bar and a temperature of 540 o C.
