    摘要: In order to stably operate a boiler using several kinds of solid fuels including depleted ash as fuels, adhesion of ash is suppressed. A calculator (9) preliminarily collects properties of a solid fuel, such as the content rate of ash and the composition of an ash constituent, as data (8). The calculator (9) uses the mix ratio of solid fuels as a parameter and calculates the composition of an ash constituent of the mixed fuels on the basis of the preliminarily measured composition of the ash constituent of each solid fuel. The calculator (9) determines a reference value of the rate of slug by which the ash deposition ratio is reduced on the basis of the relationship between the preliminarily measured ash deposition ratio and the slag ratio. Further, the calculator (9) calculates the mix ratio of each solid fuel using a thermodynamic equilibrium calculation so as to obtain an ash composition in which the slag ratio is not more than the determined reference value. On the basis of the mix ratio of each solid fuel calculated by the calculator (9), the amount of solid fuel dispensed from hoppers (1, 2) is adjusted by a fuel supply amount adjusting device (3). Thus, each solid fuel, the dispensed amount of which has been adjusted, is mixed by a mixer (4) and crushed by a crusher (5) before being supplied to a boiler (7) as a fuel and burned by a burner (6).

    摘要: A coal or carbonaceous material upgrading process for power station use, the process comprising a number of steps. First comminuting the coal or carbonaceous to a comminuted material. Second pre-treating the comminuted coal with a pulsing single frequency microwave and vacuum to reduce its water and oxygen content; the pre-treating stage being carried out at a temperature of up to 180 C Third, treating the pre-treated comminuted material with a pulsing single frequency microwave energy under vacuum to optimize the volatile organic materials; the treatment stage being carried out at a temperature of up to 350 C. Next pyrolyzing the treated coal with a pulsing single frequency microwave and vacuum to produce a hot gas and a solid carbon residue; the pyrolyzing stage is carried out at a temperature of up to 720 C. The solid carbon residue can then be separated from the hot gas, the volatile organic materials condensed to produce a liquid hydrocarbon product and a gas product; and the solid material and the gas product fed to a power station to produce electricity therefrom. The microwave energy applied at each of the stages has a single frequency of 100 megahertz to 300 gigahertz, has circular polarisation, and is pulsed at a frequency of 2 to 50 kilohertz. The pre-treatment step, the treatment step, and the pyrolysis step can be done under vacuum.
