Exhaust Gas Heat Articles & Analysis

Diesel engines reject a considerable amount of energy to the ambience through the exhaust gas. Significant reduction of engine brake-specific fuel consumption (bsfc) could be attained by recovering a significant part of exhaust gas heat. Various techniques have been proposed in the past to recover exhaust energy: mechanical, electrical turbocompounding and Rankine Bottoming Cycles. In the present ...

Operators of anaerobic digestion (AD) plants know how important it is to optimise energy use across all stages of the process. That is why many recapture as much heat as possible for reuse elsewhere, including from the hot exhaust gases generated by the combined heat and power (CHP) engines which turn the biogas from the AD plant into useful heat and electricity. Heat exchangers used for exhaust ...

Clarke Energy have been contracted by Worley Parsons on behalf of Sydney Water to design, supply and commission the GE Jenbacher cogeneration engine package, with exhaust gas heat recovery. The engines use the sewage gas produced by the on-site digesters to produce renewable power. In turn the heat generated by the engines through the combustion will go back to the digesters, increasing gas ...

ABSTRACT A diesel emissions control system built and tested on an industrial forklift truck is described. The system utilizes a pleated media type diesel soot filter. The temperature limit of the filter material is well below the temperature of the exhaust gas. Therefore, cooling of the exhaust gas is necessary. A finned-tube heat exchanger is included in the system to cool the exhaust gas to ...

Liquefied petroleum gas (LPG) is considered to be a cleaner fuel because it has less impact on air quality. However, the potential benefit of LPG usage in domestic or residential sectors in Malaysia is hampered by LPG residue in cylinder. A few critical factors, such as LPG composition, exhaustion rate and surrounding temperature, have been identified to significantly contribute to the LPG ...

High concentrations of alkali salts, iron, and phosphorus in sludge can cause operating problems in fluid-bed incinerators. Understand how clinker and scale form, and how to prevent difficulties. A major advantage of a high-temperature fluid bed (HTFB) is its ability to accept unsteady feed. Because a large quantity of heat is stored in the granular bed material, fluctuations in feed rate, ...

An integral part of the majority of anaerobic digestion facilities across the world is the CHP combined heat and power (CHP) engine. For the first time builder of a biogas plant, it is often neglected as the focus is on reducing the capital costs of the installation. However, the engine is integral to the plant, and is the key component in the production of renewable electricity, hence the ...

Combined heat and power plant efficiency is a function of the conversion efficiency of the energy in the fuel gas to useful energy in the form of electricity and heat. A combined heat and power (CHP) plant is typically a reciprocating gas engine that uses the energy in the gas to drive a crank shaft. The crank shaft turns an alternator to produce electricity. Heat is released during the gas ...

Most gas engines are Otto cycle spark ignition internal combustion reciprocating engines using natural gas as the primary fuel. Smaller models utilise stochiometric combustion while the larger engines are lean burn engines with pre-chamber ignition systems. The engines are coupled with packaged generator sets, cogeneration and, even, trigeneration units to optimise energy utilisation in the fuel ...
