Abstract

This thesis reports research into the use of brown coal briquettes
in domestic heating appliances. The performance of three
commercially available heaters was determined and a prototype heater
with improved performance was designed and tested.
Testing of the commercially available heaters when fuelled with
briquettes, wood, or a mix of the two, involved safety (in
accordance with AS2918), efficiency, power, creosote, burn time, ash
and particulate emission measurements. Results showed strong
dependence on heater design, with one design showing reasonable
performance ; efficiency of 58% and 5 grams per hour emission rate,
whereas the least satisfactory had an efficiency of 54% with an
emission rate of 36 grams per hour.
The information gained from testing these heaters and conclusions
drawn from the scientific and technical literature was used to
design and construct a briquette burning heater. The prototype built
was a downdraft heater with an inbuilt gravity feed fuel hopper. The
emission rate of the final prototype was found to be 3.54 grams per
hour, the average overall efficiency was 69% and the power output
range was 3 to 13 kW. These values were better than the original
parameters aimed for when designing the heater.
