Biomass CHP

Capitalise on Government Renewable (CHP) incentives with a short payback – act now whilst the benefits are strong

Biomass heat input of 900 kW produces 130kWe of Electricity and 700 kWt of hot water.

Providing you have a year round heat requirement for premises, industrial operations or drying operations (Wood chip for example) then this system could be ideally suited, and the RHI (Renewable Heat Incentive) returns for the heat are much greater with the addition of CHP. The electrical power can either be exported or used on site.

Environ are distributors and integrators for Uniconfort Biomass boilers and Triogen ORC systems for Biomass CHP for industrial applications in the UK & Ireland.

This unique combination allows customers to take full advantage of exceptionally good returns and payback when operating these systems as Biomass CHP (Combined heat & power) and qualifying for CHPQA acceptance. This enables support from Ofgem for the electrical power produced under ROC’s and the subsidy of the heat provided under the RHI (Renewable Heat Incentive).

We also welcome enquiries from other suppliers of Biomass fired hot air systems for supply and integration of the Triogen ORC system into your projects.

As we are now distributors for both Uniconfort of Italy for the Biomass Burner and Triogen of the Netherlands for the ORC system we can offer a complete service from the design of projects, through to construction and installation, as well as commissioning and after sales service.

The Biomass projects now installed and running in Europe have proven good reliability with 95% availability. The ORC systems have accumulated over 500,000 hours of operation with over 30 systems now installed for a variety of heat sources.

This winning combination enables us to offer the complete integrated system. The size and requirements of a typical combination is detailed below and can be seen in the photographs on this page.

Using the Uniconfort Global 90 woodchip burner it is possible to burn woodchip with up to 50% moisture content. The actual amount required depends on the type of chip used but as a guide the figures below are a mid-line on woodchip consumption at 30% moisture content.

The Biomass burner would use around 2,800 tonnes per year of chip which equates to an annual volume of 11,200 metres3. Therefore, on a weekly basis that works out at 56 tonnes per week which is 224 metres3 which equates to between 2 to 3 walking floor artic deliveries per week.

The hot gasses from the biomass burner are then ducted to the Triogen WB-1 Vario ORC system. The total heat requirement for this is 900kWt at 530⁰c. On its way to the Triogen ORC the gas goes through either an air mixer or preferably a heat exchanger to reduce the heat to the required 530⁰c. If a heat exchanger is used the heat from this can also be used to compliment the output of the system.

After this cooling stage the hot gas passes through a cyclone filter to remove the ash and impurities from it prior to entering the ORC system. This is then converted into 130kWe of electricity for exporting or on site use. The surplus heat from the condenser (cooling cycle) of the ORC is produced as hot water and is 700kWt at 80⁰c, to be used as required. The balance of the gas exits the ORC at 180⁰c and is ducted to the flue.
