Modeling Challenges for Improving the Heat Rate Performance in a Thermal Power Plant: Implications for SDGs in Energy Supply Chains

Abstract

Rapid industrialization and the increased use of consumer electronic goods have increased the demand for energy. To meet the increasing energy demand, global nations are looking for energy from renewable sources rather than non-renewable sources, to adhere with the sustainability principle. As energy from renewable sources is still in the experimental stage, there is a need to use available energy sources optimally. Considering this, the present study aims to identify, evaluate, and reveal the interrelationship among critical challenge factors in improving the heat rate performance of coal-fired thermal power plants. The study identifies twenty critical challenges through a comprehensive literature review. Then, to evaluate the identified critical challenges, the grey-DEMATEL (Decision Making Trial and Evaluation Laboratory) technique is used. For evaluating the challenges, this study conducts an empirical analysis in a thermal power plant in India. The findings reveal that air preheater leakage, coal flow balancing, and air heater air outlet temperature are the top three critical challenges hampering the thermal power plant’s performance. Additionally, fourteen challenges come under the cause group, while eight challenges come under the effect group. The findings of the study can assist industrial managers in overcoming problems in their thermal power plants. The results can also guide the development of a robust and reliable framework for mitigating these challenges.

Sustainable Development in the Coal Mining Operation: Challenges, Opportunities, and Strategies

“…Coal is one of the energy sources that is still used in the world because until now coal is a relatively cheap energy source. The International Energy Agency (IEA) predicts that the demand for coal will continue to rise in the coming decades, particularly in developing countries like India and China (Sivageerthi et al, 2022). As a result of this growing demand, there is a need for the coal mining industry to operate more sustainably to minimize its negative impacts on the environment and communities.…”

Sustainable Development Green Index: measuring progress towards sustainable development goals in the European Union

“…SDGs included five critical areas of importance by 2030planet, people, peace, partnership, andprosperity (UNDP, 2022). United Nations motivated global economies to incorporate sustainable principles in their industrial processes (Sivageerthi et al, 2022).…”

Causality analytics among key factors for green economy practices: Implications for sustainable development goals

“…It was the Brundtland committee report that underscored natural resources as being consumed at a pace beyond their capacity to be replenished; this consumption occurs in the name of industrialization despite the warnings of its adverse environmental consequences. Realizing the need to conserve natural resources and lower the impacts of global warming, the United Nations (UN) devised a set of seventeen goals known as sustainable development goals (SDGs) and appealed to global nations to incorporate sustainable principles in their industrial practices (Sivageerthi et al, 2022).…”
