Biomass heating (AM15)
About this book
This Applications Manual concentrates on biomass systems with biomass boiler outputs in the range of 50 kW to 5 MW burning woodchips or wood pellets. The major application areas for biomass boilers will be for heating systems for existing buildings, and those with substantial heating and hot water loads throughout the year. Batch-fed boilers are briefly mentioned but it does not cover hot-air heaters, biomass gasifiers or biomass chp systems.The design of biomass boiler systems is considerably more complex than that of oil and gas boiler, heat pump and chp systems, and requires an informed design approach. Integrating biomass boilers with oil and gas boilers with load circuits to form efficient and controllable hydronic systems requires a detailed understanding of the dynamics and subtleties of biomass boilers. Hence, this Applications Manual is designed to help readers understand biomass boiler systems to a level where they can make knowledgeable decisions on system design. With the exception of specific hydronic arrangements for integrating biomass boiler systems with oil or gas boilers in Chapter 7 and specific advice on health and safety requirements, this manual does not provide prescriptive solutions nor does it attempt to cover every eventuality. The primary readership of this manual is intended to be professional building services engineers in the UK.Low-carbon related legislation and regulations are changing rapidly, and also vary significantly country by country. Reference is made throughout this manual to the UK's Renewable Heat Incentive (rhi) scheme and guidance is provided on measures which may be required to secure accreditation under the non-domestic RHI. Those installing boilers to provide heat to domestic properties, and seeking support under the domestic rhi, should refer to the appropriate guidance available on the Ofgem rhi website.Readers must ensure that they are aware of, and conform with all legislation and regulatory requirements applicable to their project.
