    Abstract: 本发明为了对使用包括劣质煤在内的各个种类的固体燃料作为燃料的锅炉进行稳定运用，而抑制灰附着的情况。运算机(9)预先累积固体燃料的含灰率、灰成分的组成等性状作为数据(8)。运算机(9)使用固体燃料的混合比率作为参数，基于预先测定到的各固体燃料的灰成分的组成，来算出混合的燃料的灰成分的组成。运算机(9)根据预先测定的灰附着率与灰渣比例的关系，来确定灰附着率降低的灰渣比例的基准值。然后，运算机(9)以得到灰渣比例成为确定的基准值以下那样的灰组成的方式，通过热力学平衡计算来算出各固体燃料的混合比率。基于由运算机(9)所算出的各固体燃料的混合比率，利用燃料供给量调整装置(3)来调整来自料斗(1、2)的固体燃料的取出量。如此调整了取出量的各固体燃料由混合机(4)进行混合，在利用粉碎机(5)粉碎后，作为燃料向锅炉(7)供给，并利用燃烧器(6)使其燃烧。

    Abstract: 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).

    Abstract: 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.
