We quantified within-site variation in organic matter lost via combustion in a bog peatland in association with the 116 000-ha Chisholm, Alberta, fire in 2001. We hypothesized that for peatlands with considerable small-scale microtopography (bogs and treed fens), hummocks will burn less than hollows.

Boreal peatlands in Canada comprise a substantial store of soil organic carbon (peat), and this peat is vulnerable to extensive burning during periods of extended drying. Increased frequency of extreme weather events in boreal regions is expected with future climate change, and the conditions that would support sustained smouldering peat combustion within peatlands may be more common. Organic soils tend to burn by smouldering combustion, a very slow-moving process in fuels such as those found in peatlands. Thus the most extreme conditions for carbon loss to the atmosphere due to the burning of

The combustion rate test is carried out by burning charcoal and measuring how long it takes to turn into ash, and the mass of the burned ash.

It has been shown that the viscosity of a water-oil emulsion with a high water part (more than 50%) outweighs the viscosity of pure oil. With a low water part (10-20%), the emulsion is the most stable. With more water, the semi-delamination time decreases. Therefore, it is necessary to spray the emulsion near the site of the making.

Abstract:

The issue of mixing fuel oil with water, i. e. emulsification, is considered. Emulsified fuel of the “water-fuel oil” type is a promising alternative fuel, as it causes water to boil at high temperatures, which can improve the atomization of the fuel spray. The process of heating and evaporation of a droplet of emulsified fuel depends on the diffusion and coalescence of the smallest water particles in the fuel oil, which occur during heating. The article presents a model that accounts for the process of water diffusion in droplets of emulsified fuels, as well as the physical properties of the

The present study proposes a novel concept of a solid biomass burner for household applications. The designed biomass stove is a multipurpose burner that can be used as a cooking stove and thermal generator. It works as a basic model of a biomass cooking stove and is coupled with a coil heat exchanger for thermal generation. The experimental evaluation is conducted by using the time-to-boil (TTB) method to measure the effective energy that can be harnessed from the combustion process. It shows that the maximum temperature outlet from the coil heat exchanger is 62.2 °C. The effective energy upt
