REDUCING HEAT RATES OF COAL-FIRED POWER PLAN

2017-5-15 · problems and they affect heat rate, stack research has shown that use of power plant waste heat to reduce coal moisture before pulverizing the coal can provide heat rate and emissions benefits. The degree to which performance improves depends strongly on the degree of drying, with heat rate gains expected to be in the 2 to 4% range.

Digital, Interconnected Power Plants to Improv

The main disadvantage of this controls approach is that it is difficult to implement for the process of optimizing multiple variables. For example, a power plant operator may hope to reduce NO x and CO while improving heat rate and superheated steam temperature balance. To achieve this, DCS suppliers have included the provision for operators to "bias" the controls.

Pulverised Coal Combustion with higher efficienc

2019-10-10 · 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.
