摘要:
A method of and an apparatus for the thermal degradation of refuse, garbage and other waste material in which the waste material stream is reacted with air or oxygen in a reaction chamber for pyrolysis, destructive distillation or incineration of the waste material. The released thermal energy, spatial temperature distribution or outlet gas temperature is measured and used to control a feeder which supplies particles of a supplemental fuel, itself recovered from a waste material separate from the waste material stream, to the reaction chamber.
摘要:
A housing for protecting monitoring equipment employed to maintain watch over dusty environments. The housing comprises a cylindrical jacket (1) that accommodates the equipment. The front of the jacket is closed except for one or more apertures (12) and extends into the environment being monitored. The housing is provided with a connection (10) for a coolant or flush in the form of air. One or more outlets (15 & 17) communicate with the inside of the housing in the vicinity of the aperture and are oriented such that the air emerging from the outlets forms a cushion between the aperture and the environment being monitored.
摘要:
A method for purifyiing flue gas derived form incinerators burning refuse, wood, or sludge, in which the flue gas is cooled in a spray drier. A dust remover removes the dust from the flue gas. The flue gas is filtered through a filter-bed adsorber having filtering surfaces and packed with an adsorbent containing calcium hydroxide. The filter-bed adsorber is cleaned at intervals for removing adsorbate from the filtering surfaces. An aqueous suspension is prepared from at least some of the adsorbate that is removed from the filtering surfaces, and the flue gas is brought into contact with the suspension in at least one location upstream of the filter-bed adsorber for further separation of contaminates. The aqueous suspension is supplied to the spray drier for improving the purification of the flue gas.
摘要:
A device for stirring up gas flowing through a duct (2) accommodating one or more flat insertion structures (1) positioned at an acute angle to the main gas stream. Each structure constitutes an eddy-generating surface with a freely washed forward edge directed toward the oncoming gas and facing partly along and partly across the flowing gas. Each structure can be contoured in cross-section. The object is to decrease the weight of the structures. Each structure is accordingly basically a trapezium with two parallel edges of different length, the shorter edge of the installed structure facing upstream and the longer edge provided with an aerodynamic sweep and facing downstream. The structure is also accordingly folded along three straight lines (3) to form an .omega. or w in cross-section, with two convex folds (5) flanking a single concave fold (4).
