Review of coal-water fuel pulverization technology and atomization quality registration methods

Abstract

Abstract. Possibilities of coal-water fuel application in industrial power engineering are considered and described. Two main problems and disadvantages of this fuel type are suggested. The paper presents information about liquid fuel atomization technologies and provides data on nozzle type for coal-water fuel pulverization. This article also mentions some of the existing technologies for coal-water slurry spraying quality determination.

The Potential Incorporation of Biochar into a Char-Water Fuel — Study of Chemical and Physical Properties

“…Slurry fuels can have a significant advantage compared to using solid coal particles as water reduces flame temperature and NO x emission with little energy loss to water vaporisation; the fuel is easily stored in tanks and pumped, and; there is no risk of dust explosions [12]. The main impediments to implementation of such fuels in power station applications is producing a high char content of the slurry with high energy content without a concomitant high viscosity that causes difficulty in the pumping and atomisation of the fuel [13]. Early studies on coal-water fuels with very fine particle size (< 5 micron) and low ash (<1%) indicated suitability as a locomotive diesel fuel [14] but a commercial use of such a fuel has not arisen, and with the loss of favour of coal as a fuel this is unlikely to ever occur.…”

Numerical simulation of heat and mass transfer in a closed two – phase geothermal thermosyphon

“…The unconventional energy sources are attracting increasing attention in the conditions of continuous growth of energy consumption and fossil fuels depletion [1][2][3][4]. The active solar radiation and wind use to generate electricity and heat is hampered by huge capital and operating costs.…”
