Integrated heat and power management of buildings with the energy recovery of a cement plant

Abstract

The study aims to discuss the characteristics of heat-to-power ratios for CHP (Combined Heat and Power) systems and to understand the techno-economic impact on design and operation of CHP-based energy systems. The design procedure, subject to energy storage and energy demand profiles is suggested in a systematic and integrated manner to determine the minimum capacities of heat and power required and additionally to obtain any surplus or deficit of energy to be imported or exported. Investigation is also made to improve the cost-effectiveness for the energy management of building by integrating industrial waste heat and its use for the CHP unit. The case study is presented to illustrate how overall strategy for energy management of CHP systems are heavily dependent on power-to-heat ratio of the prime mover and to demonstrate economic benefit of heat integration between CHP-based building and an industrial site.
