Thermodynamic analysis of chimney
Thermodynamic analysis, including energy and exergy, was applied for studying a chimney phenomenon. The mathematical model of a chimney was derived and used for evaluation of output trends responsive to change of some input parameters. It was proposed to use chimney efficiency as a measure of waste heat recovery. Also, the new component of exergy of the substance, called mechanical exergy, was ...

Thermo–economic analysis of heat pipe heat exchanger for waste heat recovery in thermal systems
Thermo–economic analysis of Heat Pipe Heat Exchanger (HPHE) for waste heat recovery in thermal systems using the P1–P2 and NTU methods is presented. The optimum effectiveness of a HPHE is given as a polynomial equation, whereas the net savings and payback period are given in closed form to enable the HPHE designer to determine the optimised values directly. In addition to this, exergy analysis of ...

Heat recovery from corrosive flue gas
For improvements to energy efficiency in the petrochemical industry, waste heat recovery from corrosive flue gas is the most cost effective source to exploit During the conversion of primary energy, approximately 5-10% of the energy used is lost via hot flue gas. There is no need to emphasise that significant savings are within reach when 60-70% of refining operational costs consist of energy ...

A novel cogeneration cycle based on a recompression supercritical carbon dioxide cycle for waste heat recovery in nuclear power plants
In this study, a novel cogeneration cycle based on the recompression S–CO2 Brayton cycle is proposed, analysed and optimised thermodynamically to utilise the waste heat from a nuclear power plant. The cycle was constructed theoretically on the basis of a transcritical CO2 power cycle and a LiBr/H2O Absorption Heat Transformer (AHT) to enhance the overall performance of the cycle. It was found ...
