    Abstract: PURPOSE: To maintain an NOX value, by a method wherein, based on the result of comparison of unburnt content (UBC) in ash, produced from an estimated program, with a set UBC, a rise in the air ratio of a burner at each stge, atomization of pulverized coal particles, and carbonization in the low fuel ratio of coal used are effected in order by application of load.
    CONSTITUTION: The estimated value of a UBC is calculated by a UBC calculating computer 7, and the signal thereof is fed to a UBC setter 8 to compare it with a desired UBC set value. If the estimated value of the UBC exceeds the set value, dampers of air feed branch pipes leading to an air box 6 are opened, in order, from the lower one to the upper one to increase an air ratio. Thereafter, based on a signal sent from a mill condition setter 9, the opening of the vane of a mill 15, a load and a classifier are automatically regulated to gradually decrease the particle size of pulverized coal. Further, in response to a signal sent from a coal selector 10, coal fed to a mill 11 is gradually shifted to a low fuel ratio coal. This enables an unburnt content in ash to be kept at a low level as NOX is maintained at lower than a regulated value.

    Abstract: PURPOSE:To eliminate troubles like jamming of incombustible or combustible matter and to keep smooth flow of a fluidizing medium in a fluidized bed type heat-reactive furnace used as an incinerator or the like, by constructing the furnace to have a single internal space without providing any partitions for diving the internal space of the furnace. CONSTITUTION:Refuse put into a furnace from a refuse inlet port 60 is drawn into the flow of a fluidizing medium and gets into the top of a downward moving layer 46, so that it is burnt in the layer 46 and a fluidized bed 10. In the internal space of the furnace defined by furnace walls 61, a distribution plate 42 and a top section 59, no partitions are provided for dividing the internal space of the furnace, so that flow of the fluidizing medium is not disturbed, and incombustible foreign matter having a fairly large size can be also moved and discharged to the outside smoothly from an incombustible-matter outlet port 48.

    Abstract: A classifier capable of stably providing particles by further reducing the mixing ratio of coarse particles, a vertical crusher having the classifier, and a coal fired boiler apparatus having the vertical crusher. The classifier comprises a rotating fin (21) classifying solid particles by a centrifugal force, a cylindrical downward flow forming member (13) installed on the outer peripheral side of the rotating fin (21), a recovery cone (11) disposed under the rotating fin (21) and the downward flow forming member (13), and a housing (41). A contraction flow area (16) is formed between the housing (41) and the recovery cone (11), and a two-phase flow (52) formed of the mixture of the solid particles and gases blown up through the contraction flow area (16) is collided with the downward flow forming member (13) on the upper side of the housing (41) to form it in a downward flow. Then, that flow is led to the rotating fin side, classified into the fine particles and the coarse particles, and the fine particles are carried together with an airstream, passed through the rotating fin (21), and removed. A circulating swirl flow development suppressing part (30) is installed at the upper part of the contraction flow area (16) and on the outer periphery of the downward flow forming member (13).

    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.
