An approximate expression for the heat transfer rate of a heat recovery unit (HRU) fed by the exhaust gas exiting a microturbine operating at part-load is developed. The proposed expression can be used for various microturbine-HRU sets if the appropriate values of coefficients are used. The...

The potential to liberate steam production capacity for power generation has been assessed using actual energy consumption data and the recorded seasonal consumption fluctuations for a kraft pulp mill. The revenues from power production are compared with possible energy savings, achieved through...

This paper presents the development of benchmarking models for the ongoing commissioning of heat recovery process in a cooling and heating plant that provides chilled water and heating water to HVAC (heating, ventilation and air conditioning) systems on a university campus. The heat recovered...

In the present work, gas turbine cycles are modified with steam injection between the combustion chamber exit and the gas turbine inlet. Heat recovery steam generators, utilising the exhaust gases, provide these cycles with the injected steam at saturated vapour. The irreversibility of the...

A database of the heat demand, and surplus heat available, at United Kingdom industrial sites involved in the European Union Emissions Trading System, was used to estimate the technical potential of various heat recovery technologies. The options considered were recovery for use on-site, using...

Deployed on a commercial airplane, proton exchange membrane (PEM) fuel cells may offer emissions reductions, thermal efficiency gains, and enable locating the power near the point of use. This work seeks to understand whether on-board fuel cell systems are technically feasible, and, if so, if...

This paper presents a power generation and heat recovery model for reciprocating internal combustion engines (ICEs). The purpose of the proposed model is to provide realistic estimates of performance/efficiency maps for both electrical power output and useful thermal output for various...

The aim of this work is to elaborate a method of identification of the influence of fouling on the heat recovery in a heat exchanger network (HEN). The method is based on mathematical models enabling the interpretation of industrial measurements of operating parameters of the HEN. Details of the...

Energy efficiency and savings strategies in the combustion based industrial process heating has been reviewed comprehensively and presented in this paper. This work compiles latest literatures in terms of thesis, journal articles, conference proceedings, web materials, reports, books, handbooks...

An innovative immersed particle heat exchanger has been recently proposed by the authors: it makes use of very small solid particles as intermediate medium to perform heat transfer between two gas flows at different temperature. The potential of such heat exchanger has been already demonstrated...
