Abstract Download PDFThis research study focuses on biomass-based cogeneration power plants.
Mechanisms have been adopted to promote and regulate project implementation
of cogeneration power plants, improve or increase their energy efficiency, and
meet environmental standards, reducing local air pollution and CO2 emissions.
This paper aims to identify the parameters to monitor and assess the improvement
in energy efficiency and reduce CO2 emissions from cogeneration plants. A survey
study was first conducted for ten sugarcane processing plants with SPP (10-90
MW) cogeneration plants in the central and northern regions of Thailand. The
survey identified parameters used to monitor and control various plant operating
conditions such as operating pressures, temperatures, and steam generation flow
rates, including preventive maintenance plans to maximize the overall
performance of the power plant. A field case study was then conducted for a 25
MW cogeneration power plant in Nakhon Sawan province. The case study
involved analyzing the parameters used for monitoring and assessing the best
practice operations of a co-generation power plant and evaluating the use of
these parameters in analyzing the impacts on the energy efficiency and the CO2
emissions from the co-generation plant. ETC...
