Nitra Combined Heat and Power Powerplant

Nitra Combined Heat and Power Powerplant

3,12 MW of electricity and 3,2 MW of heat will be produced from natural gas in KGE Nitra with two cogeneration units MP 2000 M-BCU

 

The core of the local powerplant, which supplies heat to Chrenová district of Nitra city, are two container cogeneration units Martin Power with MTU engines (part of Rolls Royce Power Systems group). The biggest curiosity of the whole powerplant is that cogeneration units use the combination of standard pipeline natural gas with low-LHV natural gas from local source. Cogeneration units work in parallel with the mains and in case of power outage are securely stopped with help of MP 30 P genset.

Important factor during projection and realization was total surpression of negative noise or emission influences to surrounding housing and environment, and brownfield revitalisation after collapsed mazut heating plant with high accent to architectonic value.

Cogeneration units for natural gas

 

Cogeneration units MP 1500 C-CU and MP 250 N-CU use standard gas and supply greenhouse for growing tomatoes. Electric energy is used for supply of the lighting and heated water is used to heat the greenhouse.

MP 1500 C-CU with Caterpillar engine is installed in noiseproof 40 ft container with separate room for power and control cabinets. Exhaust gas heat exchanger with bypass, exhaust silencer and ventilation duct with dust filters are installed on the roof.

MP 250 N-CU with MAN engine is installed in custom made noiseproof canopy suitable for outdoor installation.

Cogeneration unit for biogas from corn silage

 

Cogeneration unit MP 1250 J-BCU with Jenbacher engine is installed in noiseproof 40 ft container. Due to time pressure reasons whole assembly of the CHP has been done directly on the installation site. Container features three separate rooms. Main room contains biogas genset with 999 kW power and components of heating circuit, gas regulation elements, lube oil system and other appliances. Power cabinets are located in separate room with own entrance for lowering noise impact of the engine to operator. Third smallest room is for inlet air treatment. Exhaust gas heat exchanger is located on the container roof. Stack with exhaust silencer, outlet heat exchanger and external dry coolers are located next to the container.

Cogeneration units for sewage gas

 

Two cogeneration units MP 400 G with Iveco engines have been installed in 2005 as a part of water-treatment plant reconstruction. When new operating company took over the operation of energetic center of the plant, it has been decided to replace one of the old CHP units with new unit MP 250 N-BCU with MAN engine.

Cogeneration unit works according to signal from upper level autonomous control system which regulates the power of CHP and parallel gas boilers according to actual gas production and power and heat consumption of the plant. TTS Martin company has been general contractor of this renovation responsible for supply of cogeneration unit as well as upper level control system.

Cogeneration units with low emission diesel engines for liquid alternative fuels

 

Cogeneration units Martin Power based on modified modern engines MTU are own developement of TTS Martin. Until now two MP 250 M-DCU prototypes has been put into continuous operation. Fuel used in these engines are vegetable oils, animal fats and oils made from waste plastics.

Cogeneration unit installed in 2011 in Otrokovice (Czech Republic) is container type with emergency cooler on the roof. Maximal energy input utility is achieved by using produced power, heated water from engine, oil, fuel and air cooling and also heated air from heat radiated from the engine and generator.

Second cogeneration unit of this type is installed in Moldava nad Bodvou in noiseproof canopy. Again also heated air is used besides standard power and heating water usage. This kind of using less valuable and waste fuels for energetic purposes with efficiency over 90% in modern commonrail engines is real green energy.
