“…The viscosity of the composition goes down with increasing temperature; and if at 18 °C the viscosity is 370 mPa•s, by 50 °C it reaches 250 mPa•s. This shape of the viscosity vs. temperature curve is typical of such fuels and is described in many studies, e. g., [24]. The temperature dependence of viscosity should be taken into account when planning the application of these fuels at actual power-generating facilities.…”

In this paper, the rheological properties (viscosity, shear stress, and lamination) of the promising coal-water slurries containing petrochemicals based on filter cakes have been investigated experimentally. The latter are a mixture of water and solid organic wastes produced during coal preparation. It was established that the rheological properties of coal-water slurries containing petrochemicals depend on concentrations and properties of the main components (liquid and solid, flammable, and non-flammable), wetting agents (plasticizers), as well as the storage time and conditions. The rheological properties of the fuel slurries under study were compared with the known properties of coal-water slurries based on different ranks of coal and found to match or even surpass them. Coal processing wastes have high potential as prospective components of coal-water slurries containing petrochemicals in terms of not only their environmental, economic and energy performance but also their rheological properties.

“…The technologies of production, transport and combustion of coal-water slurries (CWSs) [1] and coal-water slurries containing petrochemicals (CWSPs) [2][3][4] are urgent and modern direction of development of thermal power industry. CWS is a composite fuel that has two main components -coal (or wastes of coal processing) and water.…”

“…These wastes pose a significant environmental risk, and their storage requires considerable expenses. For preparing various compositions of CWSPs [2][3][4] the wastes of oil production and refining, pyrolysis pitches of various industries, waste motor, transformer, turbine oils and other liquid organic wastes can be used. Liquid fuel components are applied in a composition of fuel slurry as for changing the ignition and combustion characteristics, and as a plasticizing and stabilizing additive.…”

Abstract. For wide use of coal and oil processing wastes in heat power industry we investigated the structural stability of coal-water slurries (CWS) and coal-water slurries containing petrochemicals (CWSP). Three methods of evaluating slurry stability were considered. The method of evaluation of separation (into layers) of the slurry was chosen to determine the stability of fuel compositions based on bituminous and brown coal, filter cakes of bituminous coals, waste motor, turbine, transformer, compressor oils, oil, oiled mixture and mazut. The experiments shown, that the addition of waste oils (with mass fraction of 10 %) to investigated fuel compositions leads to increase of slurry segmental stability is almost by 2 times.
