Case study - Air-to-air heat exchanger provides plant heat and big savings
OVERVIEW A food processing facility installed a new Regenerative Thermal Oxidizer (RTO) for odor control from its roasting operation. The oxidizer was designed for 95% thermal rate of efficiency and included supplemental fuel injection (SFI) which is used during low VOC loading conditions, to help save fuel cost. The customer was looking at additional ways to further reduce their operating ...

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 ...

Exergy and energy analysis of an AC steel electric arc furnace under actual conditions
The energy and exergy analyses of an existing steel Electric Arc Furnace (EAF) are performed to estimate the potential for increasing the furnace efficiency. To obtain realistic results, the effect of air infiltration into the furnace was taken into account. The results of the analyses revealed that the energy and exergy efficiencies of the furnace are low and should be increased. The main ...

Energy and exergy analysis of a gas turbine power plant in Algeria
An exergy analysis of a twin ABB GT13E2 Gas Turbines (GTs) power plant (2 ? 146.2 MW) is presented in this paper. This plant is running since 2004 at F'Krina in the northeastern part of Algeria. The analysis was performed by the flow-sheet programme, 'Cycle-Tempo'. At off-design load (83%), the plant and its apparatus conserve nearly the same design load performances. However, the performance of ...

Case study - Heat exchanger retrofit
Overview A manufacturer of insulation films for the electronics industry needed to evaluate the capabilities of four existing oxidizers that treated emissions from its coating lines. The company was concerned that, due to oxidizer deficiencies, it would not meet regulatory requirements. The oxidizers had been manufactured by two different companies. One of them was no longer in business; the ...

`Variability of NOx Emissions from Precalciner Cement Kiln Systems,` presented at the 2004 AWMA annual conference
Abstract In 2003, there were forty-two precalciner kilns out of about 190 total Portland cement kiln systems operating in the United States. As a class, precalciner kiln systems have the lowest annual mass emissions of the oxides of nitrogen (NOx) per ton of clinker when compared to wet, long-dry and preheater kiln systems; however, like all cement kilns, precalciner systems experience ...
