There is a growing concern for adverse effects of untreated discharge from confined animal feedlot operations (CAFOs) in the Midwestern states. Ample data exists to show that the waste discharge from livestock operations is a major contributor to the contamination of surface water systems. The United States Environmental Protection Agency (US EPA) estimates that 41 percent of the total non-poin...

Particulates and complex organic mixtures were sampled from the exhaust of a flame retention head residential oil burner combusting No. 2 fuel oil at three firing conditions: continuous at Bacharach Smoke No. 1, and cyclic (5 min on, 10 min off) at Smoke Nos. 1 and 5. The complex mixtures were recovered by successive Soxhlet extraction of filtered particulates and XAD-2 sorbent resin with methy...

Heavy-duty over-the-road trucks require periodic active diesel particulate filter regeneration to clean the filter of stored particulate matter. These events require sustained temperatures between 500 and 600°C to complete the regeneration process. Engine operation during typical 65mile/h highway cruise conditions (1200 rpm/7.6 bar) results in temperatures of approximately 350°C, and can reach ...

The utilization of clean energy is a matter of primary importance for sustainable development as well as a vital approach for solving worldwide energy-related issues. If the low utilization rate of nuclear fuel, nuclear proliferation, and insufficient nuclear safety can be solved, nuclear fission energy could be used as a sustainable and low-carbon clean energy form for thousands of years, prov...

The goal of the latest strategy in glass companies is to decrease the cost of production while maintaining or increasing the glass quality. There are several perspective ways leading to this goal: Optimization of the heating system, Modification of the furnace design, or Installing the new advanced control system. Optimization of the heating system can be achieved by installing modern burner sy...

To better understand the combustion chemistry of tetrahydrofuran (THF) and 2-methyltetrahydrofuran (MTHF) which has been considered as promising bio-fuel, the structure of their stoichiometric (φ=1.0) low-pressure laminar premixed flame has been investigated. The flames have been stabilized on a burner at a pressure of 50 Torr (6.7 kPa) using argon as dilutant (78 %), with a gas velocity at the...

The principle of operation of the porous radiant burner (PRB) is based on porous medium combustion (PMC) in which the combustion of fuel and air mixture takes place inside a matrix of open cavities in the presence of an inert solid surface. Since the porous matrix has high thermal conductivity and high emissivity, the contributions of conduction and radiation in the PMC are significant. In the ...

The flames of forest fuels form a weakly ionized gas. Assuming a Maxwellian velocity distribution of flame particle and collision frequencies much higher than plasma frequencies, the propagation of microwaves through forest fuel flames is predicted to have attenuation and phase shift. A controlled fire burner was constructed where various natural vegetation materials could be used as fuel. The ...
