SNZ PAS 5311:2021 Biomass boilers for small and medium heat loads (external link)

The objective of this publicly available specification (PAS) is to provide best practice guidance to support the adoption of low-emission biomass boiler systems in commercial, institutional, and industrial heat applications. This PAS provides advice and information on biomass boiler systems for small to medium heat loads (50 kW to 2 MW) providing hot water below 100°C. Within this document, a biomass boiler system is one fuelled by wood chip, wood briquettes, wood pellets, or other biomass.

This PAS includes both technical and non-technical guidance on: evaluating heat demand and energy efficiency; generic site requirements; greenhouse gas and local particulate emissions; fuel quality, supply, reception, storage, and handling; operation and maintenance; system efficiency; seasonal efficiency; regulatory and non-regulatory health and safety aspects; and consenting
