At this moment (summer 2010) the gasifier has been put into operation and commissioning of the other components has started.  Because of the innovative concept several months to half a year are expected to be nessecary, to optimize the plant and to get the plant in full commercial operation.

• A moving floor for storage and feeding of manure
• A 1 ton/hour CFB fluidized bed gasifier island
• A low NO_x syngas burner
• A steam boiler
• A steam turbine
• Flue gas cleaning (a baghouse filter with additives injection)

Until this moment the plant has been operated for several thousands of hours with chicken manure during a demonstration period, to demonstrate the technical feasibility of the concept. Because of the small size of the plant and the small demand of heat at the plant site, the economics do not support a full year commercial operation. At this moment the plant is put into operation during the cold season to deliver heat to the farm (chicken stables)  and the plant is used to demonstrate the technical feasibility of gasification of specific fuels, for interested clients.

Untill now successful campaigns have been made with several fuels like bone and meat meal, RDF from waste recycling, sludge, others.

The conventional combustion of these husks comes along with excessive fouling of the steam boiler equipment, due to the high alkali content of the husk fuel. Boilers normally are cleaned manually every 2 – 4 weeks, to remove the large pieces of agglomeration from the boiler walls.

HoSt has delivered a gasifier plant, producing syngas from a feed of  1 ton/hours of sun flower husks. The syngas is used to produce steam in a steam boiler, thereby replacing natural gas fossil fuel. The plant has been put in operation in 2004.

The Dutch waterboards and de Dutch governement have signed a convenant to reduce energy consumption by 20%

The waterboard Veluwe is a leading example for this target, by reducing not 20% but reducing energy consumption by 100%. Besides reducing energy cunsumption the installation also generates the option of supplying surplus energy back to the grid. The heat demand of the nearby ecological residential area Zuidbroek in Apeldoorn is for a large part met by heat supplied by the HoSt installation.

With this by HoSt enegineered installation the waterboard Veluwe demonstrates that sustainable solution has already been found.

This year the two central themes of the day were: decentralized networks and the economic viability of projects. In the morning projects were vistited conecting to these topics.

HoSt as the leader on the Dutch market, was prominently present at the fair, and recieved a great deal of attention of the participants. The example installation at the operation centre Sterksel was visited by hunderds of interested participants, just as last year the HoSt installation at Rendac/Ecoson.

For the installation at Sterksel the new digester and a modernisation of the control was supplied by HoSt. Sterksel was exceptionaly satisfied about:

• Short construction time
• fast commisioning
• High availability (HoSt installations > 93%)
• More energy from the same products
• Simplicity

Beside the existing installation Sterksel also showed interest in the Microferm. This by HoSt designed and patented concept was presented by John Horrevorts. The microfer is a small modulair digester to convert pure manure into sustainable energy. The microferm has the following benefits for the farmer:

• Low investements
• High return
• Short construction time (only a couple of weeks)
• No methane emissions
• No other products needed
• Simple control of the installation

 

With this unique new compact plug & play technology, the customer can produce his own electricity and heat using only his manure (cattle slurry). He doesn’t have to obtain other co-products. With the digestion of their own manure a lot of CO₂ production will be avoided en methane emissions will be reduced to almost zero. This is a huge profit for the environment and for the customer.

At the same time as investing in this sustainable technology the farmer also decided to build new stables for their cattle with the newest technology regarding stable building, climate control, manure drainage etc. With this total project the company is a pioneer within the cattle farming industry and with this is able to run his farm in the best sustainable way.

HoSt started on the 8th of January 2010 with this unique sustainable project. Early in the morning the Microferm has been delivered on location with special transport. After about 5 hours of arrival on the location the Microferm was fixed and in its final place. When everything will go as planned the digester will run at full capacity and will produce renewable energy in the first half of the second quarter of 2010.

Fluidised Bed Gasification

HoSt developed a comercial thechnology for the processing of biomass using fluidised bed gasification for a scale up to 15 MWth. The technology has been developed in collaboration with the Dutch Energy Research Centre (ECN). Throught the years HoSt optimised the technology to the standard of a comercialy viable concept. HoSt already realised two installations, one in the north of the Neterlands and one in Romania.

The Technology

With fluidised bed gasification the fuel is thermally processed using a low oxygen suply. The Lowcaloric gas, produced in this process, is cleaned before burning it at a high tempreature. This processing method is very suited for difficult fuels, amongst whicht many biomass fuels.  The emissions from the installation are lower then with thermal techniques. This installation is designed to produce heat and electricity from 1 ton/h of chickenmanure. The installation will be constructed in the Netherlands. After construction the entire installation will be transported to Portugal, due to the size of the installation (11m x 4.5m x 3.5m) this will be done with  special transport.

HoSt

HoSt, situated in Hengelo Overijsel The Netherlands, is specialised in technologies for the sustainable biomass energy market. HoSt is leader on the Dutch market for supply of bio Energy installations, i.e. Biogas installations, fluidised bed gasifiers, wood fired boilers and wood fired combined heat and power units.

The current focus of HoSt is the the turn-key delivery of biomass energy installations. Within the Netherlands HoSt has a market share of aproximately 60%. Furthermore HoSt still conduct feasability studies, engineering and permit aplications for a wide selection of clients, mostly in the energy instensive industry. HoSt is specialised in developement of installations fitted to the specificed needs of its clients.

HoSt expects to produce approximately 5 fluidised bed gasifiers per year. This will be realised by further standardisation of the concept and steady contract with supliers.

Client

The client, situated in Portugal, is the maintenance and inovation branch of a major company in Portugal and Spain, including several facets of the food industry. Amongst which the raising of chicks, the porduction of eggs and the production of foor for laying chickens. To the supply the installation HoSt has been chosen after years of marketstudies to determine the best way to process the biomass in a sustainable way.

In Portugal and Spain there are many sites where chicken manure is present. By using this as fuel a sustainable solution is found to produce energy. Furthermore the clients takes it first steps on the growing market of sustainable energy.
