Mainstream industrial woodwaste-fired heating equipment tolerates a wide range of fuel types, and is usually equipped with buffer storage silos for continuous unattended operation. Stand-alone industrial composite board and wood burning installations are frequently linked to manufacturing output as a means of on-site waste management.

Surplus heat is conventionally rejected to atmosphere outside the season to prevent accumulation of unprocessed material. This may also partly be avoided by palletisation - typically reducing space requirements by two-thirds – whilst also conserving fuel stocks for retailing or winter use. Our Gallery page shows a 260 kW Dove Thermal installation at a Midlands furniture factory.

The technologies are straightforward and well established, to the extent that generous funding incentives set-up to encourage and promote renewable energy concepts reheat are being gradually pulled-in. The lower end of the combined-heat-and-power market is more difficult, given disproportionate ratios between thermal and electrical outputs. While Stirling Cycle engines have practical efficiencies of some 30%, a typical chp boiler for the domestic market delivers just 1 kWe for a thermal rating of 25 kWt.

For any chp scheme to be effective, there must be a strong, continuous base load requirement for the heat produced as a by-product of electrical generation. This has proved untenable for most domestic economies. While small engine-generators with electrical outputs in the order of 5 kWe have been developed, their operational economy when built into a packaged chp boiler has yet to be demonstrated.

There is an inverse relation between boiler- and engine-driven systems: in the former, boiler heat output governs generating capacity, while in engine-generator systems electrical demand governs heat production. Flexible micro-chp is engine-based: practicable machines start at about 15 kWt output as waste heat from engine generators producing 5 kWe.

Dove Thermal Engineering has designed and built several wood-waste boiler plants, and associated factory heating installations. We have helped our clients register with the Renewable Heat Incentive, and gain self-supplier status on the Biomass Suppliers List (BSL). We follow-through and support the making of returns under the schemes, and – given they are subject to peremptory audit - ensure that the correct reporting procedures are maintained.
