Thermoeconomic operation optimization of a coal

situation significantly, and today, technology is capable of producing power from coal with very modest emissions with a fairly good combustion efficiency. Emissions can be reduced by either adding new equipment like more efficient burners, or by better operation of the power plant by better tuning of the process variables. This article · Process controls can improve low-load process stability in normal modes of operation, allowing operating points to be optimized within process and plant …investment cost and operation cost). For the first time, operation optimization on a 300 MW coal-fired power plant located in Yiyang (Hunan Province, China) is accomplished based on the structure theory of thermoeconomic. Two optimization strategies, global optimization and local optimization, are succes­ sively realized on the power plant.
