Energy Use and Environmental Impact
Published in B K Bala, Energy Systems Modeling and Policy Analysis, 2022
The combustion of wood in wood stoves releases particulate matter, carbon monoxide, hydrocarbons and other pollutants. At most times of the year, this does not cause serious problems in the rural areas where wood is typically burned, especially in developed countries, but under atmospheric conditions known as temperature inversions, which occur relatively frequently in the winter in some temperate localities, wood smoke can be retained within small valleys, allowing pollutants to build up to levels that can exacerbate or cause respiratory problems.
Magnetism
Published in Daniel H. Nichols, Physics for Technology, 2019
An induction stove creates heat in a metal pot by generating a current in it through electromagnetic induction. If the resistance across the pot is 2 × 10−3 Ω, and a current of 300 A is flowing through the pot, how many watts of heat is being created in the pot?
Air Quality and Site Plan Review
Published in Robert M. Sanford, Environmental Site Plans and Development Review, 2017
The visible portion of wood smoke is mostly unburned fuel. Consequently, there is less of it when stoves become more efficient. Wood stoves emit smoke, soot, carbon monoxide, and about a hundred other chemical gases, including many carcinogens. Large residential subdivisions, especially in the “second home” market may have enough wood stoves to cause air quality problems in small valleys with frequent winter air inversions. A preventative measure is to ensure the development has efficient stoves. If the wood stoves are EPA certified, then they must meet “Phase II requirements.” These requirements should be sufficient to reduce potential air pollution from new wood stoves.

Baking the Injera is a unique and the most widely practiced daily operation in Ethiopian households carried out by the women. The traditional wood burning stoves generate a considerable amount of air pollutants. The amounts of PMs and TVOCs pollutants measured in the baking of Injera during the wet season are relatively higher than those measured during the dry seasons using different types of stoves tested. Furthermore, the levels of TVOCs are much higher than the levels of PMs emissions from each type of stove in both the wet and dry seasons. Generally, the levels of PMs emissions found in this study using the clean stove are lower than the levels found using the traditional stoves. Thus, the Injera bakers (women) are subjected to lower degree of pollutants exposure when using the clean stove and hence they are less susceptible to the exposure-related health risks.
Induction assisted friction stir welding: a review
Published in Australian Journal of Mechanical Engineering, 2020
All metals show electric resistance while conducting electricity. The resistance to this flow of current causes losses in power that result in the formation of heat. Some metals, such as silver and copper, have very low resistance and, as a result they are very good conductors. Copper wires are used to carry electricity through power lines because of the low heat losses during transmission. Other metals, such as steel, have high resistance to an electric current, so that when an electric current is passed through steel, substantial heat is produced (Bhadeshia and DebRoy 2009). The steel heating coil on top of an electric stove is an example of heating due to the resistance to the flow of the household, 60 Hz electric current. In a similar manner, the heat produced in a part in an induction coil is due to the electrical current circulating in the part (Robson, Kamp, and Sullivan 2007).

However, handling, storage and transportation costs are increasing due to their low density and high moisture content (Garcia-Maraver et al. 2015). Therefore, its direct use is not suitable for the environment and economy. Inefficient and incomplete burning of wood or biomass in stoves produces smoke laden with fine ash and dangerous carbon monoxide and hydrocarbons (Ghassemi 2001).
