Nazko Valley Elementary School & Community Centre in Quesnel, BC

Background

The Nazko Valley Elementary School & Community Centre was retrofitted with a biomass heating system to take advantage of lower fuel costs and carbon credits from reduced greenhouse gas emissions.

 

The Viessmann solution

A fully containerized Pyrot wood-fired boiler system was commissioned to provide space heating for the 17,000-square-foot building.

 

Installation details

A heated biomass system enclosure – complete with a Pyrot KRT-300 boiler, piping, pumps, mixing valve and storage tank – was installed in only two days. A pellet silo with a capacity of 47 tonnes and an automated feed system ensure a consistent fuel supply for the boiler.

The Pyrot is equipped with the industry-leading control and safety devices to ensure reliable and safe operation. Its advanced combustion process, triple-pass heat exchanger and modulating output control enable the boiler to achieve an efficiency of 85% while maintaining low emission levels. An automatic de-ashing system minimizes maintenance, and a web interface allows remote system monitoring.

 

The results

The 100% biomass heated facility uses locally sourced wood fuel (generated from timber destroyed by the pine beetle), displacing approximately 86,400 litres of propane and 130 tonnes of CO2 emissions every year.
