HRS helps AD plant tap into additional heat from existing CHP
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 ...

Assessment of a CHP system based on economical, fuel consumption and environmental considerations
Combined heat and power (CHP) systems which are able to produce heating and power simultaneously, are getting more attention since they have many economical and environmental benefits. CHP systems for buildings are an important application of CHP on various systems designs. In this study, we have investigated a CHP system applicable for the building of Azad University of Shahrood. The prime mover ...

Heating Value
The lower heating value (LHV) or higher heating value (HHV) of a gas is an important consideration when selecting a gas engine or CHP plant. Gas engines efficiency is typically quoted based upon the LHV of the gas. Whenever a hydrocarbon fuel is burned one product of combustion is water. The quantity of water produced is dependent upon the amount of hydrogen in the fuel. Due to high combustion ...

New technology enables biogas plant optimization
Governments around the world are seeking to lower greenhouse gas (GHG) emissions in the fight against climate change, to reduce waste to landfill, and to increase their utilisation of renewable energy in compliance with international agreements. Consequently, in many countries, subsidies have been made available to encourage the growth of the biogas sector. According to the International ...

Emissions and performance of a stationary diesel engine run on biodiesel blends
This paper presents an investigation into the effect of biodiesel blending on emissions and efficiency in a stationary diesel engine. Rapeseed based biodiesel blended in increments of 25% with fossil diesel. The emissions of CO2 show a decrease in emission (g/kWh) with increased engine load. Within the range of tests carried out, the NOx emissions from biodiesel and its blends proved to be higher ...

Sokratherm compact CHP units with fully integrated SCR catalyst
For our compact CHP units with turbo engines we offer an emissions reduction solution with SCR catalyst fully integrated into the CHP unit’s sound absorbing case. It complies with all limit values of the German 44. BImSchV and and can already reliably reduce the NOx emissions below the limit value of 0,1 g/Nm³ which will be mandatory from 1.1.2025 on. The CHP units can be equipped with ...

Exergy and exergoeconomic analysis and optimisation of diesel engine based Combined Heat and Power (CHP) system using genetic algorithm
In the present study, a diesel engine based Combined Heat and Power (CHP) system is optimised using exergoeconomic concept and genetic algorithm. For this purpose, the CHP system is first thermodynamically analysed through energy and exergy. Then cost balances and auxiliary equations are applied to subsystems. Finally an objective function representing fuel cost, cost of exergy loss and ...

Using biogas for combined heat and power
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 ...

Gas engines for resiliency of site operation
The choice to deploy a combined heat and power (CHP) system, utilising reciprocating gas engines, is often an investment decision to help drive cost and carbon savings to an organisation, whose focus is not traditionally, power generation. Clarke Energy have deployed CHP in numerous ‘critical’ applications around the world; whereby a power outage could cause considerable disruption ...
