Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling the NOx concentration of a discharge gas in combustion equipment in which dust coals are used as a fuel, with which the NOx concentration of a discharge gas emitted from the combustion equipment in which dust coals are used as a fuel can be easily lowered to or below the regulation value according to the Air Pollution Control Law, etc. by performing control beforehand on the basis of the properties of the dust coals, and in addition, the amount of a denitrifying agent or the like to be used for the control can be reduced.SOLUTION: In this method, multiple kinds of dust coals are each examined beforehand for the rate of reaction of the char, and a relationship between the NOx concentration of the discharge gas and the reaction rates is determined in advance. The multiple kinds of dust coals are blended so that the rates of char reaction give a value which corresponds to an objective or lower NOx concentration, on the basis of the relationship, and the dust-coal blend is supplied as a fuel for the combustion equipment.

Abstract: PROBLEM TO BE SOLVED: To stably operate a boiler using several kinds of solid fuels including depleted ashes as fuels by suppressing adhesion of ashes. SOLUTION: A calculator 9 preliminarily collects properties of a solid fuel, such as the content rate of ashes and the composition of an ash constituent, as data 8. The calculator 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 determines a reference value of the rate of slug by which the deposit ratio of ashes is reduced on the basis of the relationship between the preliminarily measured deposit ratio of ashes and the slag ratio. The calculator 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 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. 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: Mineral additives and a method for operating a waste-to-energy furnace are provided in order to improve its operational performance and availability, increase the lifetime of the combustor building materials (refractory walls and heat-exchanger metallic tubes) and flue gas treatment equipment, improve ash quality, reduce emissions and avoid combustion problems such as agglomeration, slagging, deposition, and corrosion. A method for operating a waste-to-energy furnace, such as a fluidized bed reactor, pulverized-fuel combustor, grate combustor includes introducing mineral additive into the furnace. The method further includes heating at least a portion of the mineral additive either intimately in contact with the fuel, such that the ability of mineral additive to induce crystallization of the surface of forming ashes is enhanced, or minimizing the contact of the mineral additive with the fuel and the forming ashes, such that the solid-gas reactions between the mineral additive and the volatile compounds in the flue gas are favored and the mineral additive power to capture at least a portion of the inorganic volatile compounds present in the furnace is enhanced.

Abstract: A fossil-fuel-fired system, which includes an emissions-control-agent dispenser, a furnace, an emissions monitor and, optionally, a controller, is disclosed. The emissions-control-agent dispenser provides a prescribed amount of organic-emissions-control agent, such as, for example, an opacity-control agent to the fossil-fuel-fired system. The furnace includes an exhaust communicating with the atmosphere. The emissions monitor is capable of measuring at least one property of the flue-gas communicated through the exhaust to the atmosphere. For example, when an organic-emissions-control agent is an opacity-control agent, the emissions monitor has the capability of at least measuring opacity. When included, the controller communicates with at least the emissions-control-agent dispenser and the emissions monitor.
