This paper studies the heating load and thermal comfort distribution in a typical office with a mixed radiant and convective heating system for two different locations of radiant heat sources. Accurately estimating the heating load in a mixed heating space requires careful consideration of the energy balance on each room surface and the comfort level in the space. A pure radiant heating system ...

A series of photo-oxidation smog chamber experiments were performed to investigate the primary emissions and secondary aerosol formation from two different log wood burners and a residential pellet burner under different burning conditions: starting and flaming phase. Emissions were sampled from the chimney and injected into the smog chamber leading to primary organic aerosol (POA) concentratio...

Recommended Citation Emadi, Majid. "Flame structure and thermo-acoustic coupling for the low swirl burner for elevated pressure and syngas conditions. ABSTRACT Reduction of the pollutant emissions is a challenge for the gas turbine industry. A solution to this problem is to employ the low swirl burner which can operate at lower equivalence ratios than a conventional swirl burner. However, flame...

Abstract: Properly understanding heat flux characteristics is a crucial prerequisite to efficiently applying a regenerative burner in an aluminum reheating furnace. A series of experiments was conducted in this study in order to establish a database of the best available burners according to furnace temperature, excess air ratio, and flame combustion mode as they affect heat flux characteristic...

This study is focused on the effects of nitrogen content in biomass feedstock on the producer gas composition and the flue gas NOx emissions from a pilot-scale gasification and combustion system. Biomass gasification has the potential to produce carbon negative energy by using renewable resources. The greenhouse gases emitted by burning fossil fuels have to be reduced, and biomass gasification ...

An improved understanding of cool diffusion flames could lead to engines. These are investigated here using a spherical porous burner with gaseous fuels in the microgravity environment International Space Station. Normal and inverse burning ethane, propane, n-butane were explored various fuel oxygen concentrations, pressures, flow rates. The diagnostics included an intensified video camera, rad...
