ACEP Researcher Daisy Huang to Travel to Tanana for Biomass Boiler System

Project Description:

This project seeks to examine performance of wood-fired hydronic boiler systems in three different Alaskan communities. Performance of the boilers has been monitored using an energy metering system comprised of an inline flow meter, and two temperature sensors, one on the hot water supply side and the other on the return side. By tracking the water flow rate and the temperature at both sides, the amount of heat input to the water can be obtained. By correlating this against wood consumption and wood moisture content, a rough measure of boiler efficiency may be obtained. Additionally, an emissions probe will be brought to each site during an extremely cold time and during a moderately cold time. During these visits, stack emissions will be measured.

Project Update:

Daisy Huang will travel to Tanana to collect data from the Btu meter installed on a biomass boiler system comprised of two Garn boilers connected in series. The Biomass Boiler Performance Evaluation Study report will be available in a few months.
