Combined heat-power systems with gas engines are thermal systems in which natural gas is used as fuel and electricity is produced as the main output and heat as the side output is produced simultaneously and within the same system. In cogeneration systems (CHP), electricity and heat generation (in hot water, steam form); in trigeneration systems (CCHP), electricity, heat and cooling production is carried out. Electricity generation is realized from natural gas burned in the gas engine at an efficiency of up to 42.1 %; exhaust heat, engine coolant, intercooler circuit and lubrication oil heat can be used to increase the total efficiency (electrical+heat) of the system to 95%. Combined heat-power systems can also be integrated with renewable energy sources (solar/wind) to minimize grid dependence.
ESCON designs high efficient and plug-and-play cogeneration/trigeneration systems with package type technological container solutions and performs field installation within 24 hours.
Trigeneration systems (CCHP) are combined heat-power systems which natural gas is used as fuel and electricity (as the main output), heat (in the form of hot water, steam) and cooling are produced as the simultaneous side output.
Trigeneration systems basically work in the same logic as cogeneration (CHP) systems; the only main difference is that cooling is achieved by absorption cooling groups in addition to the current heat output.
Organic Rankine Cycle
Organic Rankine Cycle (ORC) has the same principle as the Rankine Cycle in which water is used as a fluid, and systems in which an organic fluid is used and electricity is produced from low temperature heat sources. Organic fluids provide higher cycle efficiency than water at low temperatures, prevent wear problem in turbine blades and make electricity production economical.
With the single stage impulse turbine enables electricity generation from high flow saturated steam. It is package type and fully automated. Non-bearing turbine design, which is directly coupled with no gearboxes allows minimum maintenance and operating costs thanks to no lubrication requirements.
