PELLEMATIC CONDENS_e PROJECT

 

Efficient, CO2-neutral heat generation for the single-family home with the additional benefit of generating green electricity with their own pellet boiler - these are the objectives to be achieved with the Pellematic Condens_e.

In order to ensure the highest possible flexibility, the basic concept of the power-generating pellet boiler is built on the Pellematic Condens. Thus, a simple retrofit of the power generation at a later point in time is simply possible and without a high expenditure of time.

 

In the following subitems are displayed the used technology, the main project milestones and all relevant information about Pellematic Condens_e.

From September 2017 the Pellematic Condens_e is ready for series production in Austria and can be realized in many other EU countries during the pilot phase.

PELLEMATIC SMART_e – PELLET HEATING WITH STIRLING ENGINE

 

Structure of the Pellematic Condens_e

 
<strong>Bildvergrößerung</strong>

This pellet boiler with integrated Stirling engine for the single-family home is a further development of the Pellematic Condens - a highly efficient pellet boiler.


The Pellematic Condens_e is the most compact solution from ÖkoFEN for generating heat and green electricity. The combustion concept of the already existing Condens boiler was optimised for the integration of the Stirling engine. To enable easy retrofitting of the Stirling engine at a later date the e-ready module was developed. This module contains all relevant interfaces - both hydraulic and control technology - to ease a simple and time-saving integration of the power generation in retrospect. This module can be ordered for each Condens to keep all options open for the future.


An intelligent cleaning concept integrated into the Condens_e also makes it possible to clean the heat exchange surfaces of the Stirling engine in a fully automatic manner. This ensures reliable operation with minimum maintenance.


In addition, in order to provide the best possible flexibility in the operating time of the plant, a buffer storage volume of at least 600 liters is prescribed together with the condense. This is about decoupling the power generation from heat generation in order to be able to realize the highest possible power requirements. Thanks to this buffer memory, the operating times can be optimized and adapted to the basic electricity requirements of the respective house.


Additionally, the Condens_e has graded power levels. During the transitional period or during the summer months, the thermal output of the system is reduced to 9 kW. As a result, the plant can still be optimally operated even at times of lower heat demand, and the generation of electricity can thus be achieved at the best times.


On colder days, the power-generating pellet heating system automatically increases the thermal output and can provide a peak power of up to 13 kW. The rated electrical capacity of the system is - under optimal conditions - up to 600 watts.


In addition to the heat supply (due to combustion), the cooling of the Stirling engine (due to the return temperature of the heating circuits) is also important for the good current output of the system. The cooler the return temperature, the more efficient the Stirling engine can operate. For this reason a low temperature heating system (underfloor heating) is recommended in combination with the Condens_e.

MICROGEN STIRLING ENGINE

 

Microgen Engine Corporation has been working for many years on the development of a free-piston Stirling engine that is suitable for mass production. Since 1995, the enterprise has invested 200 million euros into the development of this concept; efforts that have been paid off with both technological and commercial success. As a result, the Microgen Engine Corporation has been the world's only successful mass producer of Stirling engines with this power range since 2010, when tey first became a commercial viability.
Many world-renowned companies, such as Vaillant and Viessmann also rely on the Microgen Stirling engine and use it in gas micro-CHP systems.
The Microgen Stirling engine produces alternating current (50 Hz) and can provide a maximum power of 1 kW.

How it works

 
  • The displacement piston pushes helium through the regenerator from the head to the cooler. 
    The spring on the opposite casing at the bottom pushes the piston back upwards.
  • The helium is alternately heated and cooled, and as a result it expands and contracts again. 
    This causes the creation of a pressure wave, which repeats as the cycle begins again. 
  • The working piston is moved up and down by these pressure waves up and down.   
  • The magnetic working piston is surrounded by a fixed magnetic coil with copper windings, which means that an alternating current is generated.

 

This cycle is repeated 50 times per second, generating AC power at 50Hz.

MILESTONES IN THE DEVELOPMENT OF ELECTRICITY HEATING FOR THE SINGLE-FAMILY HOUSE

 

Based on the good experience with the Microgen-Stirling engine in the Pellematic Smart_e, this Stirling engine is also used for the Condens_e for pellet power generation.

 

The primary goal of the development of this current-generating pellet heating system was that the power generation module is easy to retrofit with the standard condenser. Due to the thermal and electrical performance of this system, the Condens_e is ideally suited for the single-family home.
