Clean Fossil Fuels
Our vertical combuster is the largest, most advanced facility of its kind in world. Studies improved ways of capturing CO2 to reduce greenhouse gases and decrease emissions of acid rain precursors, i.e. SOx, NOx and flyash from coal combustion. Flue gas recycling offers a means of capturing CO2 without having to dilute the product gases with nitrogen and avoids the need for gas separation after combustion. CanmetENERGY’s 1 million BTU/hr vertical combustor operates at temperatures of up to 1800oC. The facility is highly flexible. Designed to burn coal, natural gas or oil and can be modified for other fuels.
Flame Research Tunnel Furnace
The furnace was conceived as a versatile facility for the study of combustion aerodynamics, burner performance and the characterization of pollutants in relation to flame properties and of heat transfer from flames. It is 5.25 metres long and one metre in diameter. Although in most trials the facility is operated at a nominal value of about 1.5 GJ/h and controlled at a 3% or 5% excess oxygen level in flue gas, the furnace was designed for a thermal input of 0.7 MW (2.5 GJ/h) and can be fired with a wide range of flame performance conditions.
Pilot-scale Research Boiler
Our research boiler is a U-shaped furnace with a vertical refractory-lined shaft and vertical steam boiler connected at the bottom through a horizontal refractory-lined tunnel. It is fired by opposing twin burners which can be located in 3 basic positions, known as the I, J, or U configuration. The furnace is normally operated at about 1.5 GJ/h in order to reduce the overall fuel consumption requirement for each test.
Fuels Assessment and Emissions Lab
One of the key research areas is the assessment and development of combustion technologies for various fuels including renewable and unconventional fuels for clean and efficient energy production. Our researchers have developed new assessment methodologies and established combustion characteristics of conventional petroleum residual fuel oils, biodiesels and biofuels, just to name a few.
Another focused area is the development of novel methodologies for toxic emission measurements. Our team developed a new on-line real-time measurement of mercury species measurement methodology for emission monitoring at coal-fired power plants and a new source dilution measurement for PM 2.5 that provides realistic air pollution data that is comparable to the urban ambient particulate matter we breathe.
Fluidized Bed Combustor
The combustor exploits the combination of high efficiency combustion of low-grade fuels with reduced emissions of sulphur and nitrogen oxides (SOx and Nox ). This particular laboratory has specialized equipment necessary for fluidized bed combustion research such as a pilot-scale circulating fluidized-bed combustor with a bed area of about 0.12m2 and a pilot-scale (0.78m2) bubbling bed combustor to study corrosion, erosion and the fate of trace metals in feedstocks. The bubbling fluidized bed unit is designed to operate at temperatures up to 1100 ºC and at superficial gas velocity up to 2m/s.
CARS Laser
We have developed a non-intrusive measurement technique, known as Coherent Anti-Stokes Raman Spectroscopy (CARS), for monitoring flame temperature and identifying chemical species in flames. The technique can readily assist manufacturers in designing burner systems for the combustion of a wide range of solid and gaseous fuels.
CARS uses laser beams to measure the temperature and species concentration non-intrusively at any point in a flame envelope. The laser shows precisely what is happening inside each element of a flame, even when conditions are changing rapidly over a short span within the flame envelope. This capability is quite unlike the conventional, intrusive sampling probes, which can disturb the chemistry of the flame and distort the results sought.
Computer Modeling Lab
A sophisticated combustion simulation capability is available to serve industrial needs. This modelling capability can be used to predict the service performance of combustion equipment, including combustion characteristics, NOx emissions, fuel consumption, heat transfer and fluid flow. We are committed to the advancement of combustion simulation technology through collaboration with the private sector and the research community.
Our combustion simulation capability is the product of 20 years of research and collaboration with academa and commercial software developers. Its development is based on work initiated at the University of London’s Imperial College, the University of Waterloo and ANSYS Canada Ltd. It can simulate performance of utility boilers, industrial furnaces, combustors or kilns of any geometry using a wide variety of fuels.
