The goal of the project was to develop a new wildland fire sprinkler capable of stream-height adjustment. A Fire Cobra prototype was built base on a design from a team of University of Alberta Mechanical Engineering students. Through field tests, the prototype was inferior and would require additional modifications to become functional.
A modified rainbird sprinkler was tested and it produced 8 m semi-vertical stream. The conclusions reached from the testing included that is possible to use an attachment kit to modify an existing kit sprinkler and farther engineering would be required to provide for a more streamlined kit design capable of sustaining the desired pressure ranges.
Over the course of the project a new industrial sprinkler called the FireBozz was identified in the market place. The legs of FireBozz can be adjusted to change the stream angle height.
Over the past 25 years, an average of more than 8,000 forest fires have occurred each year in Canada. The average area burned annually during this period is equivalent to 2.3 million hectares, or almost four times the almost four times the size of Prince Edward Island. In some years when there are many fires the amount of wood burned can exceed the amount of wood harvested. What impact will climate change have on on fire in Canada's boreal forest? Can we predict and control it? These are the questions that researchers from the Canadian Forest Service are addressing.
Depuis 25 ans, plus de 8 000 feux de forêt se sont produits en moyenne chaque année au Canada. La superficie moyenne brulée annuellement durant cette période équivaut à 2,3 millions d’hectares, soit presque quatre fois la superficie de l’Île-du-Prince-Édouard. Certaines années où les feux sont nombreux, la quantité de bois brulé peut même dépasser celle de bois récolté. Quel impact aura le changement climatique sur les feux dans la forêt boréale canadienne? Pouvons-nous le prédire et le contrer? Voilà des questions auxquelles s’intéressent des chercheurs du Service canadien des forêts.
Innovation in hotspot target equipment used for Infrared (IR) testing reduces risks and logistical challenges. This InfoNote describes the development of a new hotspot prototype for use at the IR grid in Hinton, Alberta.
Modified oxygen consumption calorimetry was used to track the seasonal flammability of black spruce and tamarack. Age class related samples were collected for both species from May to September at research site in central Alberta. These samples were assessed for their differential heat release using test equipment at the Protective Clothing and Equipment Research Facility (PCERF) at the University of Alberta.
The test method was able to successfully quantify the differences in seasonal flammability between black spruce and tamarack. Data showed the age-related flammability differences were less pronounced, with the exception of new growth samples early in the season.
The services offered related to forest operations are outlined in this general brochure. Information on workshops, professional services, virtual library, online tools and opportunities for assessment and support are detailed.
