Abstract:
A method and system for using plastic material as a fuel includes dissolving the plastic material in biodiesel to form a solution. After the solution is created, it is filtered to remove insoluble contaminants and is then fed to a generator that oxidizes the solution to create power and/or heat. Heat from the oxidation of the solution can be utilized to facilitate the further dissolution of plastic material in biodiesel and to reduce the viscosity of the resulting solution.
Abstract:
The present invention discloses a method for treating sewage sludge by using circulating fluidized bed combustion. The method includes the following steps: (1) preparing the slurry of sludge with coal, by mixing fine coal and dispersant with sludge, then adding stabilizing agent; (2) burning the slurry by feeding the slurry into a circulating fluidized bed boiler which containing fluidized media of quartz sand and limestone. The preparation of the slurry also includes the steps: firstly, waste water is adsorbed/filtered by fine coal and Ca0, then others fine coal is added into the result sludge, thus the slurry is obtained.
Abstract:
Plant for the heat treatment of waste material, comprising means (10) for supplying the waste material to be treated, two chambers (20, 21) arranged in parallel, a thermal dissociation reactor (30) for treating the waste material, means for collecting the solid residues formed in the reactor (30) and means (34, 35, 36) for collecting and condensing the formed residual vapors; the plant is characterized in that the chambers (20, 21) are provided with pressure reducing means (8), and in that the plant is also provided with a combustion chamber (81) supplied by the residual vapors formed in the reactor (30) and in the chambers (20, 21).
Abstract:
The present invention is directed to a kiln and associated apparatus for use in a method of treatment of solid and liquid wastes. A kiln (10) is provided, of the type including a kiln casing lined with refractory material. A hopper (24) is provided to supply a pelletized mixture of clay and waste material to the kiln, which is of the updraft type. Flue gas is exhausted to a precipitator/heat exchanger (32) which heats the incoming air charge. The incoming pellet charge is preheated by a portion of the heated combustion air in preheater (21). The kiln (10) is fired to a temperature above 1300 degrees Celsius to produce a stable, ceramic pellet at high thermal efficiency.

Abstract:
A fuel flexible furnace (20), including a main combustion zone (25), a reburn zone (26) downstream from the main combustion zone (25), and a delivery system 30, 110) operably coupled to supplies of biomass and coal and configured to deliver the biomass and the coal as ingredients of first and reburn fuels to the main combustion zone (25) and the reburn zone (26), with each fuel including flexible quantities of the biomass and/or the coal. The flexible quantities are variable with the furnace (20) in an operating condition.
Abstract:
A waste water disposal method using an industrial combustion equipment, comprising the steps of detecting the operating state of the industrial combustion equipment by signals from a flowmeter for fuel supplied to the industrial combustion equipment, and accurately and properly controlling the flow of waste water, whereby undisposed waste water can be prevented from being discharged during low combustion, before stopping combustion, and immediately after ignition and a fuel system, combustion chamber, and flue can be prevented from being affected by the mixing of the waste water to provide an optimum waste water disposal according to the types of the waste water and combustion equipment.
