Engine cooling system unit (IEC thermal module)
The engine
cooling system is designed for diverting heat energy from the engine jacket,
oil and fuel mixture cooling. The outfeed of heat energy is carried out with
the help of cooling radiators.
The engine
cooling unit (IEC thermal module) is supplied mounted on a separate frame that
is installed next to the engine, it includes the following equipment:
- Expansion tank of the engine cooling circuit
- Expansion tank of the engine fuel mixture cooling circuit
- Shut-off and safety valves, instruments and meters

Emergency cooling radiator
The
emergency cooling system is designed to dump heat of the engine cooling system
and ensure uninterrupted operation of the cogeneration module in modes both
with partial heat load and without it at all through the radiator. The radiator
is designed for an ambient temperature of 32°C.
The radiator
delivery package includes the functionality of smooth change of fan rotor
speed, which allows reducing power consumption in variable operating modes and
preventing premature failure of the fan motors in the winter, when some of the
fans stop, the blades become iced and freeze, which leads to overheating and
failure of the motors at the next start. This functionality is provided either
by installing a frequency converter, or by using electronically commutated fans
(EC) in the radiator.
Exhaust silencer
The exhaust silencer is designed to reduce engine exhaust noise. It is designed for a residual sound pressure level of 65 dB(A) at 10 m (as measuring zone level according to DIN 45635) measured in the exhaust pipe.

GENERATOR OPERATING MODES:
1. In parallel with the electric power system networks
Generator operation is possible only if the mains switch is permanently closed (at least one of the inputs of the external power system network). In the event of an accident in the network / frequency voltage drop, an emergency shutdown occurs.
The next functions are included:
- Generator operation in parallel with the electric power system networks;
- Automatic disconnection of the generator from the power system network in case of deviation of the parameters of frequency, voltage with graduations on the generator switch.
2. Island operation - autonomously with no connection to the electric power system
Generator operation is possible only if the mains switch (-es) is permanently open or lack of power system mains at the site. Accordingly, mains failures/voltage or frequency drops do not affect the operation of the generator. The generator is the only source of power supply for the facility. When operating in standalone (island) mode, it is recommended to have standby equipment. The number and capacity of backup units are determined based on the requirements for the reliability of power supply to consumers of the facility. When several units are used together on the same bus section, the station control panel (MCS) is required in the scope of supply, which is offered if there are no power system networks at the facility. Accordingly, mains failures/voltage or frequency drops do not affect the operation of the generator. The generator is the only source of power supply for the facility. When operating in standalone (island) mode, it is recommended to have standby equipment. The number and capacity of backup facilities are determined based on the requirements for the reliability of power supply to consumers of the facility. When multiple units are used together on the same bus section, the Station Control Panel (MCS), which is supplied OPTIONALLY, is required in the scope of delivery.
The next functions are included:
3. Combined
In this mode, the "parallel" mode of operation (with a permanently closed mains switch) is taken as the basic one. In the event of a mains failure/voltage or frequency drop, the mains switch trips. At the same time, the generator keeps operating, the control system transfers it to the “island” mode. The "island" mode operation is performed until the network is restored on the mains switch. When the stable mains voltage is restored, the control system automatically synchronizes the generator together with the connected consumers with the power system network at the mains switch. Then the generator continues operation in the "parallel" mode of operation.
The next functions are included:
- Generator operation in parallel with the electric power system networks;
- The blackstart function – generator startup from batteries when there is no bus voltage;
- Import/export control - organization of continuous measurement of the actual electrical load on the circuit breakers (CB) with subsequent automatic/manual adjustment of the electrical power of the generator in line with the actual consumption of electricity. With auto-adjustment, after the generator is switched on, the control system continuously measures the generated power and the load consumed by the connected consumers. They are compared in real-time and, if necessary, automatic adjustment of the power of the generator/generators to achieve zero (or set by the operator) balance on the communication line with the power system;
- Automatic disconnection of the generator from the network of the power system in case of deviation of the parameters of frequency, voltage with the shift to the "island mode of operation" to the allocated load of consumers, subject to a positive value of the "export" of electricity, with graduations on the corresponding switch breaker SB1 (or SB2).
- Operation of the generator in island mode without connection to the network of the power system;
- Subsequent automatic synchronization of the generator with consumers on the switch breaker SB1 (or SB2) with the power system network, after restoring normal network parameters at the corresponding input.
- Automatic switching on by the control system of the switch breaker SB1 (or SB2), in case of an emergency shutdown of the generator, when operating in the "island mode", after opening both generator switches.
Diesel gensets with power from 3 to 50 MW (megawatt)
Heat recovery system from a gas-powered electrical generator
For MTU 16V4000L64FNER gas-powered electrical generator a heat recovery system provides the next advantages:
- Increasing the overall efficiency up to 89.1%
- "Free" 2055 kW of heat energy (at 100% generator load)
- Independence from heat suppliers
In the MTU 16V4000L64FNER gas-powered electrical generator, the heat energy of the following flows can be usefully used:
1. The thermal power of the engine cooling system is 1060 kW, including the heat power:
- Oil cooling,
- Water cooling of the motor jacket
- 1st stage fuel mixture cooling
2. The thermal power of the exhaust gas flow when cooled down to (120 °C) is 995 kW The total useful thermal power of the MTU 16V4000L64FNER is 2055 kW.
COGENERATION - a joint production of electricity
and heat
Depending
on the heat recovery system used, the useful heat power of the gas-powered
electrical generator can be converted:
- Hot water recovery system - 2055 kW of hot water with a temperature curve of 70/80... 100ᴼС
- Steam recovery system - in 1060 kW of hot water with a temperature curve of 70/80... 85ᴼС and 995 kW of saturated or superheated steam, pressure 6...32 bar
TRIGENERATION
– a joint
production of electricity, heat, and cold
The ‘Trigeneration’
solution is interesting for clients with a need for a cooling load in the form
of cold water with a temperature of +1 ... +15ᴼС. The proposed solution is based on the use of
absorption lithium bromide refrigeration machines, which convert thermal energy
into cold energy in the form of cold water with a temperature of +1 ... +15ᴼС.
