Energy units-Based Heat and Power Stations
ENCE GmbH (ЭНЦЕ ГмбХ) Engineering Company offers innovative energy-saving technologies through its network of representative offices in Russia (Moscow, Nizhni Tagil, Ufa, Lipetsk, Cherepovets), Ukraine (Kiev), Kazakhstan (Atyrau, Almaty), Uzbekistan (Tashkent), and Baltic states– stations and plants for generation of electricity, heat and cooling (trigeneration) based on energy units- within the framework of complex measures aimed at enhancing economy’s energy efficiency.
The extensive way of energy sector development is the trivial increase in volume of mined fuels in the far-off regions and the increase in quantity of new power facilities built with old technologies. The intensive energy sector development emphasizes effective power-saving and provides for the use of innovation technologies to generate heat and electricity.
The objective of ENCE GmbH (ЭНЦЕ ГмбХ) Engineering Company is enhancement of energy saving along with improvement of the ecological situation and environment protection that are burning issues in many regions. New consumers may be connected with minimum expenses for development of auxiliary infrastructure. Alongside with that there is no problem finding land for new energy facilities and there's no need to organize sanitary and protection zones.
Mankind at large exerts negative impact on the environment. One can dramatically reduce this impact implementing innovative power generation technologies free from emission of greenhouse gases, detrimental impurities, burning residues.
ENCE GmbH (ЭНЦЕ ГмбХ) Engineering Company believes that the most promising technologies is the innovative power generation technology used in energy units, i.e. oxidation of liquid or fluid fuel without burning it.
Heat and power plants on energy units are manufactured for industrial as well as for domestic use.
An energy unit is a device that makes it possible to produce electricity and heat from fuel with high hydrogen content in the course of a silent flameless electrochemical reaction. Unlike other power generating devices, like internal combustion engines, turbines that burn gas, oil, coal, energy units don't burn any fuel. Thus there's no need for noisy high pressure rotors, high level exhaust noise and there’s no vibration. Chemical energy of fuel is directly transformed into electricity, heat and water.
There are several types of energy units depending on application conditions and the fuel type. The types of fuel used include natural gas, propane, synthesis gas, methanol, diesel fuel and pure hydrogen.
Due to a number of undeniable advantages over traditional power sources and power supply schemes autonomous heat and power stations on energy units take more and more significant place in production of "green" energy and heat. In addition, they are installed directly at the consumer's location. The important stimuli for its widespread usage are also the increase of the gas prices, as well as charges for services of gas and power providers.
In accordance with the legislation oil companies have to utilize up to 95% of associated petrol gas. This problem is particularly urgent in Russia and Kazakhstan. It is widely known that cleaning and conditioning of associated petrol gas in order to bring it to the state of natural gas is not economically sound in case of low production volumes. Thus associated petrol gas is simply burnt but first of all it is harmful for the nature and human health, and secondly – it is simply waste of money and resources. This direction is thus considered extremely profitable and prospective for use of heat and power stations based on energy units fueled by associated petrol gas. Economic advantages of such stations are beyond all expectations. In fact, heat and energy are generated from fuel that costs nothing and that was previously burnt in torches in order to get rid of it.
This innovation opens a new door for usage of energy unit-based power plants.
Conveniently heat and power stations on energy units can be categorized into several classes according to nominal electric output:
Portable stations (less 1 kW)
Energy units of this class are used in:
- Electric appliances, communication tools
- Portable devices
Portable energy unit-based power sources are characterized by high energy efficiency. The smallest of them are made to be used instead of the batteries in mobile phones, laptops and other portable electronic devices. They are low powered, maximum 100 W.
Its main innovative advantage is the usage of methanol – cheap liquid fuel that is easy to transport, store and distribute and has extremely high specific power capacity. The larger stations are made to be used in low power energetic. Innovative energy units with direct oxidation of methanol are an ideal and reliable energy source for mobile and portable devices with the power up to 250 W. They are used all over the world as an effective power source for recreation and leisure activities, electric vehicles, non-electrified industrial machinery and mobile and stationary devices of special purpose.
Small stations (less 50 kW)
ENCE GmbH (ЭНЦЕ ГмбХ) Engineering Company distinguishes the following major applications of small stations based on energy units:
- Wireless communication
- Communication and data transfer network
- Safety systems
- Public heating and power generation
- EMERCOM facilities
- Single objects with partial seasonal availability
Energy units are reliable, noiseless, have less moving components compared to a generator, have a higher range of operating temperatures compared to a battery: -40°C to +50°C and as the result have extremely high energy efficiency. Also, operating expenses on such station are lower compared to the generator. Lower spending on energy unit is the result of just one maintenance visit per year and much higher productiveness. Finally, a energy unit is an ecologically friendly technological solution with a minimal environmental impact.
Energy unit-based power stations provide backup power source for crucial infrastructures of communication network for wireless, constant and broadband communication, support of classified communication networks, data transfer networks, such as high-speed data networks and optical fiber pathways, systems of monitoring and access control using video surveillance systems (ID card readers, devices for door closing, biometric identification devices etc), automatic fire alarm and fire extinguishing systems, elevator control system. With the power range from 250W to 15kW, they provide a number of unsurpassed innovative parameters.
Reliable, having high energy efficiency and free from toxic emissions, heat and power stations on widely available natural gas and renewable fuel sources are used on different markets, from home power generation to energy supplies to distant regions, as well as backup power sources. They are used in universal heat and power plants that combine production of power and energy, and distributed generators that produce both heat and energy for household usage. Those energy-saving systems produce heat for space and water heating and power that can be used in the household and redirected back to the grid.
Midrange stations (less 1 МW)
ENCE GmbH (ЭНЦЕ ГмбХ) Engineering Company suggests that energy units of this class are used in:
- Industrial, municipal and public services objects
- Cool storage plants
- Telecommunication centers
- Sport facilities
- Objects in ecologically clean regions that are removed from gas and electric networks
- Objects that can't get power sources due to the limits on gas and power supply in the location
- Dormant deployment facilities
- Autonomous objects, buildings and constructions with high and uneven energy consumption.
Decentralized stationary plants are made for combined production of heat and electric power, and in combination with cooling devices of absorption type – for combined production and trigeneration of electric power, heat and cold.
Power stations can be used with a number of different gaseous or gasified types of fuel that are characterized by low toxic emissions and high power and thermal efficiency coefficient. It emits 35-40% less carbon dioxide to the atmosphere than a regular gas-powered power plant (per each KW/hour of produced power), or 67% less than a coal-powered station. They are made for continuous operation for several years. The level of toxic emissions (carbon monoxide, nitric oxides etc) of the new power station is really low. Its advantage is no power losses during distribution of electricity in industrial network that ensures high energy efficiency.
