Speyside High School - Case Study
Biomass integration into an existing LTHW system
Korrie installed a 800kW wood chip biomass boiler and modified the existing LTHW system to utilise the biomass plant to operate as the primary heat source at Speyside High School. The scope of works set out by Moray Council required the main contractor, Robertson Construction, to create a purpose made external blockwork constructed plant room. This space was designed to house the biomass boiler plant, buffer vessel, press unit and circulation pumps. Adjacent to the biomass plant room was a 100m3 silo complete with a wood chip elevator fuel delivery system for maximising the storage capacity of the silo.
The biomass system was integrated into the existing school LTHW system via a shunt pump connected to the low loss header within the school plantroom. The automatic control system was modified to utilise the biomass system as the principal heat source. The scope of works also included the replacement of existing oil boilers with 2 sectional cast iron boilers located within the existing school plant room.
As a result of the installation of a biomass system, Moray Council will receive substantial Government funded RHI payments for the next 20 years. The financial benefits will also be complimented via a reduced carbon footprint which will serve to protect the interests of the client and the larger community in the forthcoming years.
