Mixing of a lignin‐based slurry fuel

The Canadian Journal of Chemical Engineering, 2000
AbstractLignin‐based slurry fuels are a potential alternative to fossil fuels in kraft pulp mills. Lignogels — mixtures of lignin, fuel oil, water and surfactant — are non‐Newtonian fluids, with shear‐thinning and thixotropic behaviour. Their mixing was investigated in tanks with volumes of 3 and 30 L.

Promising components of waste-derived slurry fuels

Journal of the Energy Institute, 2020
Abstract The paper presents the results of experimental studies of energy (calorific value, ignition delay times and threshold ignition temperatures, duration and temperature of combustion) and environmental (CO2, NOx and SOx emission) characteristics of fuel slurries based on pulverized wood (sawdust), agricultural (straw), and household (cardboard)

Gas anthropogenic emissions during slurry fuels combustion

AIP Conference Proceedings, 2019
Coal consumption in the world is growing rapidly, approaching oil consumption levels or even exceeding them in some states. Coal-fired power plants have a well-known negative impact on the humankind and environment. Coal processing produces a lot of high-ash wastes.

Single-droplet combustion of coal slurry fuels

Combustion and Flame, 1983
Abstract The combustion characteristics of single droplets of coal slurry fuels were experimentally investigated using both spontaneous and forced ignition. Results showed that the combustion is a sequential two-staged process, consisting of gas-phase combusion of the volatiles followed by combusion of the solid residue, which is mostly carbon.

Catalyst Complexed Carbon Slurry Fuel Development.

1981
Abstract : Catalyzed carbon blacks and a control sample were prepared for the purpose of evaluating the effectiveness of the catalyst in the improvement of carbon slurry combustion. Two batches (100 pounds each) of carbon black containing 0.2 and 0.99 percent iron catalyst highly dispersed within the carbon structure were produced.

Developing anthracite coal water slurry fuel

Fuel and Energy Abstracts, 1996
Abstract : Public law has directed the Department of Defense (DOD) to increase the use of coal, particularly anthracite, at steam generating facilities. This study evaluates the feasibility of producing slurry fuel from anthracite coal and examines the combustion characteristics of the anthracite/water fuel slurry.

Coal fuel slurry for internal combustion engines

Solid Fuel Chemistry, 2013
A technoeconomic study of the production of coal-water fuel slurry for internal combustion engines and thermal power plants was performed. Based on the accumulated experimental data, it was found that, in the calculations of the fuel efficiency of coal-water slurries, the production costs were incorrectly taken into account; this led to a doubtful ...

COMBUSTION OF DECANE-BASED SLURRIES WITH METALLIC FUEL ADDITIVES

45th AIAA Aerospace Sciences Meeting and Exhibit, 2007
Low-density decane-based slurries were prepared with powders of mechanically alloyed Al 0-7 Li 0.3 , nanocomposite 2B + Ti, and pure aluminum. The slurries were atomized using an ultrasonic nozzle. The aerosol was focused into a laminar vertically rising jet and ignited in air to produce a lifted flame. Combustion was studied optically.

Studies of Slurry Fueled Propulsion Systems

1972
Abstract : A one-dimensional equilibrium thermochemistry program, originally written for air-augmented rockets, was modified to accommodate calculations for a boron slurry fuel. The program was used for the prediction of combustion temperature, product species, and air specific impulse values as a function of total equivalence ratio. The results of the

Mathematical simulation of the combustion of slurry fuels

Combustion, Explosion, and Shock Waves, 1995
A mathematical model is proposed for the combustion of slurry fuels in the quasi-one-dimensional approximation. A numerical simulation is made of combustion of a slurry based on carbon and toluene in a combustion chamber and in a nozzle. The completeness of the combustion of the slurry is found to depend strongly on the excess oxidant ratio αox with ...
