摘要： A method operates a furnace unit with a feed chute and a camera for capturing an image of the surface of the chute. The chute includes a slide on which material flows to a grate, and the coverage of the chute and in particular of the slide with material, the burning bed thickness and the burnout zone are determined by an image evaluation.

摘要： A biomass gasification system for producing aqueous or water gases after biomass has been carbonized is disclosed. Temperatures of a thermal decomposition and gasification furnace can be quickly and uniformly stabilized with smaller thermal loss. Reaction residuals after thermal decomposition and gasification are prevented from adhering on the inner surface of the system. The biomass gasification system comprises: a main body, a first cylindrical member, a first cut-out member, a first cylinder accommodating therein a first screw conveyor, a second cylindrical member, a second cut-out member, a second cylinder accommodating therein a second screw conveyor. The first cylinder is so constructed that it penetrates the main body, the first cylindrical member and the first cut-out member in an axial direction. The first screw conveyor, the second screw conveyor and the second cut-out member have a plurality of gasifying agent ports, respectively.

摘要： A method for drying solid fuels prior to injection and burning in solid fuel boilers is described. High moisture content solid fuels such as bark, sludge, wet coal, etc. must be dried before they can burn. Embodiments of the present invention incorporates a fuel delivery chute integrated with the boiler wall using a flow of combustion gasses and radiant heating to partially dry the solid fuel before it reaches the combustion zone of the boiler. The combustion gasses are drawn through the delivery chute by means of the flowing fuel and air jet inductors that then blows the combustion gasses back into the boiler. A refractory wall separates the fuel chute from the boiler proper, is heated by the combustion in the boiler, and radiates heat to the fuel falling through the fuel chute.

摘要： The reactive waste deactivation facility includes a plurality of deactivation bays each being adapted to accommodate a different type or reactive waste which is to be deactivated therein. The deactivation bays are all enclosed within a common expansion chamber that is designed to collect waste gasses and other wastes resulting from the deactivations that take place in the plurality of bays. In addition, an air pollution control system is provided for cooling and treating the waste gasses before they are vented to the atmosphere. The facility may also include a remotely operable waste feeding system for enabling an operator to safely feed or charge each of the bays. A waste collection and removal system is also provided, which includes an individual, remotely operable, releaseable floor connected to each of the bays.

摘要： A method and apparatus is described for environmentally sound usage of combustible hazardous waste as supplemental fuel in operating rotary cement kilns. The apparatus comprises an open port in the rotary vessel at a point where during cement kiln operation the in-process mineral material is in a calcining state and where kiln gas temperatures are sufficient to decompose volatile components of the waste fuel. A drop tube extending from the port into the kiln is provided to prevent in-process mineral from escaping through the port during rotation of the rotary vessel. Combustible solids are delivered through the port under the force of gravity and air is continuously drawn into the rotary vessel through the open port during kiln operation. The apparatus and method allow efficient usage of combustible solid waste as a supplemental fuel for cement kiln operation.

摘要： A method for burning fuels, particularly garbage, in incinerators with a stoker grate, for which the primary air is supplied below the stoker grate into the fuel layer and the secondary air is supplied above the fuel layer, is controlled in such a way that the intensity of the combustion of the fuel on the stoker grate is increased by increasing the oxygen content of the primary air and the intensity of the combustion in the secondary combustion zone is choked by decreasing the oxygen content in the secondary air. Flue gas, preferably from the combustion process, is recirculated in order to reduce the oxygen content of the secondary air.
