30 YEARS EXPERIENCE
BIOGAS and BIOMASS power plants became important type of renewable power plants because these power plants use and consume animal and environmental wastes and generate electricity from these wastes instead of keep these wastes in nature.
Özçlik Elecreomechanical Ltd. Co is the solution partner of the HoST BV company and both companies are carrying out Bioenergy projects in Europe, Turkey and neighbourhood countires.
HoSt is the largest supplier of bioenergy systems in the Netherlands & Europe and delivers complete systems, from anaerobic digesters for agriculture and industry, wood-fired boilers and combined heat and power plants to fluidised-bed gasifiers.
Because of HoST BV’s own Research and Development divisions’ studies and developments, Host has been developing his own systems and product licences and accordingly HoST became the leading Biomass system producer and supplier about the wood-fired boilers and combined heat and power plants to fluidised-bed gasifiers.
ANAEROBIC DIGESTERS – AGRICULTURAL
Microferm: compact system of 65 – 150 kWe in two designs with a combined heat and power (CHP) unit for the production of power and heat, or a biogas upgrading system where the biogas is refined to natural gas quality. The system processes fresh slurry and is suitable for slurry volumes of between 3,500 m3 and 7,000 m3 per year.
Farm-type digesters from 250 kWe to 2500 kWe
These anaerobic digesters are designed with a flexible supply system suitable for a wide range of solid biomass flows. The concrete digester tanks, fitted with special mixers enable extremely dense biomass flows to be mixed. With its sophisticated design, which almost doubles the capacity in comparison to the traditional concept, the large volumes of gas production per digester enable quick returns on initial investment.
ANAEROBIC DIGESTERS – INDUSTRIAL
From sludge digestion to category 3 waste material In industrial anaerobic digesters organic waste flows are processed without the addition of slurry. For example, HoSt has constructed numerous systems for the digestion of slaughterhouse waste. To this end, for the processing of category 2 material, various thermal pressure hydrolysis (THP) systems have been supplied, as a result of which the conversion of biomass is improved significantly. HoSt also supplied systems for processing unpacked food products, industrial food product and for the processing and maximum energy recovery of industrial and municipal primary and secondary sludge.
BIOWASTE-FIRED CHP INSTALLATIONS
High-yield biowaste-fired CHP plants
HoSt supplies biowaste-fired combined heat and power (CHP) plants up to 12 MWe. These relatively small plants are high-yield as a result of combining a self-cleaning high-pressure boiler and a high-efficiency steam turbine. The HoSt combustion technology is highly flexible in applicable fuels: such as moisture contents ranging from 10% to 55% and fuels with low ash melting points like straw, chaff , manure, olive pulp, chicken manure and RDF (Refused Derived Fuel).
Biowaste-fired grate boilers of 2 MWt to 50 MWt
For low emissions and additional flexibility when it comes to wood quality, the robust furnace is designed with a hydraulic input, a stepped grate and stepped incineration. Flue gases are re-circulated under the grate and in the furnace so that manageable incineration and minimum emissions result.
In order to optimise management and control of the digestion process, HoSt provides a process analysis:
- no process failure as a result of acidification, salification, etc.;
- increase in gas production;
- reduction in feeding costs;
- defining of fertilisation value of the digestate.
PROCESS IMPROVEMENT WITH ENZYMES
Enzymes for digesters are produced with the aid of fungi. With the aid of enzymes the mixing process and the mass transfer are improved, the breakdown of particles is enhanced and the formation of foam can be avoided.
HoSt has its own laboratory with four small-scale digesters. By simulating actual digesters the digestion process can be optimised and biogas yields can likewise be defined for each specific product per customer.
PROCESS SUPPORT AND MAINTENANCE
Because of the sophisticated operating controls on the systems, HoSt is able to monitor and optimise processes remotely. In combination with our maintenance programmes, this ensures high-efficiency installations.
