Combined Heat and Power (CHP) essentials
'CHP essentials' introduces the concept of power and heat 'production possibility sets', starting at the cradle of CHP, i.e., the thermal power generation plant. The latter always occasions 'fatal' heat that is either recovered (the 'merit' of CHP) or wasted (condensing). This split paves the way to defining the production possibility sets of CHP plants, shown for steam turbines, internal ...

Qualifying Combined Heat and Power (CHP) activity
The EU 2002 draft and 2004 final CHP Directives propose qualifying CHP activity with the quality norm. This norm benchmarks the energy efficiency of CHP plant outputs on external reference power and heat efficiencies. Because the quality norm amalgamates cogeneration and condensing activity its application entails particular perverse effects for high-quality and adapted scale investment in CHP ...

Quantifying Combined Heat and Power (CHP) activity
In CHP plants without heat rejection facilities power, output is complementary to the recovery of heat, and all activity is cogeneration. CHP plants with heat rejection facilities can operate a mix of cogeneration and condensing activities. Quantifying the energy flows of both activities properly requires knowledge of the design power-to-heat ratios of the CHP processes (steam and gas turbines, ...

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 ...

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 ...

The effect of precooling inlet air on CHP efficiency in natural gas pressure reduction stations
Almost all pressure reduction stations in Iran use expansion valves to reduce the natural gas pressure, which leads to wasting large amount of exergy. In this paper, a system is proposed which includes the modification of a conventional pressure reduction station with the addition of a turbo expander and a gas turbine for power recovery and generation. The next step is investigating the effect of ...
