    • A waste materials processing system and method for combusting solid waste material on grates in combination with comminuted waste material being combusted in suspension within a combustion zone. Conduits are positioned external to the combustion zone around which exhaust gases from the combustion zone pass. Comminuted waste material is driven through the conduits and by pyrolytic action emit gases which are collected and passed to a recovery system. Additionally, pre-dried sludge and sludge vapors derived from sanitary sewage are incorporated into the combustion zone for burning. The combined waste materials processing system may be incorporated within a steam generating system in order to increase the overall efficiency of the boiler.
    • 用于在炉内燃烧固体废料的废料处理系统和方法,与在燃烧区内悬浮的粉碎废料相结合。 管道位于燃烧区的外部,燃烧区域的废气通过燃烧区。 粉碎的废料通过导管被驱动,并通过热解作用排出被收集并传递到回收系统的气体。 另外,将来自卫生污水的预干燥的污泥和污泥蒸气并入燃烧区用于燃烧。 组合的废物处理系统可以并入蒸汽发生系统中,以便提高锅炉的整体效率。

    • Heavy hydrocarbon containing sludges such as refinery waste streams, oil storage tank sludges and marine oil tanker ballast are treated by passing the sludges in a flow stream through an indirect dryer to vaporize liquids having a boiling point at atmospheric pressure of less than about 700.degree. F. and to provide substantially dried solid particles discharged from the dryer. The dried particles, containing heavy hydrocarbons as a coating or as a part of the solids, are conducted to a combustor/oxidizer and exposed to a high velocity flow stream of oxygen containing gas, typically low pressure forced air, to burn the residual hydrocarbons in the solids and to reduce heavy metals and the like to oxides thereof. A sludge handling system includes a rotary disk type indirect dryer connected to a lift pipe type combustor/oxidizer for thorough exposure of the dried solids to an oxygen containing atmosphere. A centrifigal or cyclone type gas-solids separator receives the flow stream discharged from the lift pipe and a portion of the dried solids may be diverted after discharge from the dryer back to the dryer inlet to reduce the moisture content of the sludge flow stream introduced to the dryer to minimize caking and clogging of the dryer itself.
    • 通过使流动的淤泥通过间接干燥器将含有大量压力的沸点低于约700°F的液体蒸发,从而处理含有重质烃的污泥如炼油厂废物流,储油罐淤泥和海洋油罐车镇流器 并提供从干燥器排出的基本干燥的固体颗粒。 将含有作为涂层或作为固体的一部分的重质烃的干燥颗粒被导入燃烧器/氧化剂并暴露于含氧气体(通常为低压强制空气)的高速流动流中,以将 固体并且将重金属等还原成其氧化物。 污泥处理系统包括连接到提升管式燃烧器/氧化器的旋转盘式间接干燥器,用于将干燥固体彻底暴露于含氧气氛。 离心式或旋风型气固分离器接收从提升管排出的流动流,并且一部分干燥的固体可以在从干燥器排出到干燥器入口之后转向,以减少引入到 干燥器,以最大限度地减少烘干机本身的结块和堵塞。

    • A combustion chamber capable of being directly fueled with green bark, green sawdust and the like material formed of refractory material, the chamber having a grate therein at the feed end thereof disposed towards the bottom of the chamber and a reduced outlet and having means for delivering particles of fuel material generally downwardly towards the grate while separating and enveloping the particles with pressurized turbulent air, and means for directing air upwardly through the grate against the downwardly directed air enveloped fuel particles in sufficient volume and with sufficient pressure and velocity to effect turbulent suspension of a substantial proportion of the fuel particles above the grate, the chamber further being air tight apart from the fuel and air input feeds and the outlet whereby the chamber is adapted to operate on a positive pressure with respect to the external ambient pressure.
