- Offer Profile
- WELTEC BIOPOWER® plans and
produces complete biogas plants made of stainless steel and distributes them
WELTEC BIOPOWER has been so successful that it has evolved into the world
market leader of this segment over the past few years. No other manufacturer
has enjoyed as much success abroad as WELTEC BIOPOWER®.
To further build on this success we have established subsidiaries that
should handle customer requirements on a local level in several countries
like England, US and other Eastern European countries.
Agricultural Biogas Plants
- Using biomasses like liquid manure or corn offers
impressive possible rates of return. The generated biogas can be directly
transformed into usable energy that can be sold profitably. Let’s plan your
project together—from the cost-effective compact system with a capacity up
to 150 kW through to large-scale plants in the megawatt range!
Get the most out of it! The heat generated during the
conversion from biogas to power (CHP) can effectively be used in
greenhouses, pigsties, homes, or for drying wood pellets. This combination
of heat and power greatly increases the efficiency and profitability of a
biogas plant. Alternatively, the biogas can be transferred to a suitable
buyer through a small-scale gas grid for use in a CHP. No matter how you use
your energy (power, heat, fuel), WELTEC BIOPOWER definitely means more
Industrial Biogas Plants
- The biogas plant technology of WELTEC BIOPOWER utilises
the fermentation of renewable resources and at the same time offers a wide
variety of solutions for treating waste. Be it leftover food, slaughterhouse
waste or other organic residual materials, everything is possible!
Organic waste is an energy resource. Animal waste
products, kitchen waste, domestic and industrial food waste, used cooking
oil, etc. are all perfectly suitable for utilisation in industrial biogas
plants. Exploit your energy potential:
WELTEC BIOPOWER offers you sustainable solutions in the field of industrial
waste and disposal technology and ensures optimum integration with the other
technologies in your process. Combined with smart heat utilisation concepts,
you can benefit in two ways and perpetually enjoy maximum energy efficiency.
- Another innovation by WELTEC BIOPOWER is
The generated biogas is converted to natural gas quality in a special
process and supplied as biomethane to the existing natural gas network. Take
a step towards the future with WELTEC BIOPOWER!
Biomethane refineries of this size require an advanced
degree of specialised plant technology. A high level of automation, precise
plant control systems with process control, and efficient remote maintenance
solutions are vital. Furthermore, adaptation to on-site requirements is very
important. WELTEC BIOPOWER analyses the local conditions and provides
bespoke sustainable solutions for the entire biomethane production chain.
- A reliable system is the result of optimally and finely
tuned technologies: The substances used have to be comminuted, mixed
together and heated, the gas obtained is further processed and harnessed
That’s why WELTEC BIOPOWER only utilises plant components that have proven
themselves in use and develops the majority of the technologies
- The heart of a biogas plant is the fermenter where the
biological processes take place. As a result we attach great importance to
this component. The gas composition which is very aggressive when forming
attacks many materials. That’s why only resistant materials are implemented
in the biogas area of WELTEC systems. The material of choice for tank
construction and internal components is here stainless steel—rustfree.
For instance, the tank wall is constructed in two different materials due to
the different operational demands:
- Stainless steel V2A (1.4301/AISI 304) in the liquid content area
- Stainless steel V4A (1.4571/AISI 316Ti) in the area of the gas
- Several individual factors determine the optimal
operation of a biogas plant. To ensure that these factors are optimally
matched with each other WELTEC BIOPOWER® has equipped the plants with a
central control system that controls and manages all processes.
Smaller plants require a relatively simple system that will reliably control
all major factors. More comprehensive plant types require normally a more
sophisticated control system.
We therefore individually match our control systems depending on the
individual requirements of the required plant.
All main plant operations are recorded, analysed and controlled by our
central control and measuring system.
This technology is based on a system, which has matured over years and is an
integral part of our plant technology.
A refined agitator technology is decisive for a reliable and efficient
mixing of the fermenting substrates and forms the basis for an even yield of
gas. Depending on the individual fermenter size a combination of long arm
and submersible agitators are used.
Long arm agitator
The task of a long arm agitator is to mix the substrate evenly and
carefully. At approx. 40 rpm it creates a flow in the vessel and ensures
that the gas creating bacteria will have continuous and optimal conditions.
In addition to the long arm agitators we also use submersible agitators.
These agitators ensure a fast and targeted mixing of floating and
sedimenting substrates and are used to maintain a minimum crust formation in
the digester, and to break up larger problematic crust formations in the
- There are several variations to feed the fermenter with
fermenting substrates, which mainly depend on the consistency and
characteristics of the individual substrates.
If you mainly use fluid and easy to mix substances, the transport of the
substrates within the plant is managed via a central pump, which can be
installed either in a building or in a container.
Combined Heat and Power Unit (CHP)
- To convert the biogas produced in the plant to
electricity and heat energy a combined heat and power unit is required.
This is why WELTEC BIOPOWER® integrates suitable solutions for CHP units
directly into the plant design.
Depending on local conditions a CHP unit can be erected in a building or in
an external container.
- Complete Plants with Complete Service
In order to provide best advice every plant will be supported by our trained
distribution partners on site and right from the start and during every
phase of the project.
