    摘要: A system for detecting a combustion-related condition in a pulverizer includes a pulverizer configured to receive coal chunks via an inlet, to grind the coal chunks into coal powder and to output the coal powder via an outlet. The system includes sensors configured to detect heat input characteristics supplied to the pulverizer and heat output characteristics emitted from the pulverizer. The system also includes a controller configured to determine, based on signals from the sensors, whether a combustion-related condition exists in the pulverizer based on a heat balance function including the heat input characteristics and the heat output characteristics.

    摘要: A tangentially-fired furnace for the burning of anthracite is disclosed. The furnace may contain a boiler with a chamber having four corners. Four burner groups located at the four corners may be configured to eject pulverized coal flow into the chamber for combustion, in order to form a single fireball substantially at the center of the chamber during combustion. Each burner group may contain a first burner which includes primary-air/rich-portion nozzles for ejecting rich-portion coal flow into a lower section of the chamber, and a second burner which includes primary-air/thin-portion nozzles for ejecting thin-portion coal flow into a higher section of the chamber.

    摘要: A method and system for processing biomass material from harvest to pelletizing includes a continuous shredding stage and grinding stage to reduce the size of the material. A fan pulls air through the shredder and the grinder to assist the movement of the biomass material through the shredder and the grinder. Due to the light weight of the biomass material, the material is transported between the shredding and grinding stages mechanically and pneumatically by a combination auger with air assist. The biomass material may include agricultural residues, such as corn stover. The process and equipment eliminates or minimizes damage to the carbohydrates in the biomass so as to maintain pre-grinding cellulose and hemi-cellulose levels.

    摘要: 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.
