Cogeneration refers to the technological process through which both electrical and thermal energy are produced simultaneously, using a smaller quantity of fuel than the separate generation of the same amount heat and electric energy.
Because of this, TEB is one of the initiators and proponents of energy efficiency solutions using GE Jenbacher gas engines (natural gas, biogas, landfill gas, etc) .
GE Jenbacher gas engines have a high heat recovery rate from the water running through the cooling system– cooling water, lubrication oil, exhaust gas, generating heated water temperatures of up to 90°C and/or saturated steam in the pressure range of 2 – 12 bar through a recovery boiler.
The thermal energy serves different purposes, depending on each separate case:
a) Hot water (normally heated up to 90°C) for:
• District heating
• Space heating (industrial warehouses, office buildings, hospitals, schools, kindergartens, etc)
• Industrial processes (different temperature levels)
• Trigeneration (simultaneous generation of electrical/mechanical energy, heat and cooling)
b) Saturated steam (pressures between 2-12 bar) for:
• Industrial processes, hospitals, etc
ADVANTAGES OF HIGH EFFICIENCY COGENERATION BY GE JENBACHER GAS ENGINES
• Electrical power interval from 250 KW to 9.500 KW;
• Total efficiency 82 – 91.6 %;
• Use of a wide variety of combustible gas ( natural gas, biogas, associated petroleum gas, mine gas, special gases, etc);
• Using calorific gases value between 1 KWh/Nm3 and 30 KWh/Nm3;
• Compact installations, which do not require large placement spacing;
• High reliability and availability;
• Reduced investment implementation period (6-8 months);
• Reducing emissions in the environment;
• Major overhaul after 60 000/80.000 operating hours;
• Solutions endorsed by the Romanian and European legislation;
