A system and method for treating, injecting and co-combusting sludge in a municipal waste or other solid fuel combustor. The system includes a sludge receiving and treatment module and a sludge injection and combustion module. The sludge is received and stored in one or more storage hoppers where its moisture content is monitored and varied to obtain a sludge having a desired moisture content. The treated sludge is then pumped to a furnace injection nozzle where it is preferably atomized with steam and sprayed into the combustion zone of the furnace. Improved odor control in sludge handling is also provided by a storage tank and a sludge tanker trailer each having an air diffuser for mixing and aerating the sludge and a filter system for filtering odors.

Processes and systems are provided that include introducing ammonia liberated from organic waste to a coal burner in a coal burning power plant, preferably for NOx removal at the power plant. The ammonia is preferably either ammonia liberated upon drying a mixture of organic waste and coal combustion by-products or ammonia liberated when organic waste is mixed with coal combustion by-products and one or more alkaline additives. Also provided are processes and systems of fueling a coal burner of a power plant with coal and either a dried mixture of organic waste and coal combustion by-products, or a mixture of organic waste, coal combustion by-products and one or more alkaline additives. The present invention is further directed to mixtures of either organic waste and coal combustion by-products, or mixtures of organic waste, coal combustion by-products and alkaline additives made by the processes of the present invention.
摘要:
A method of injection and combustion control and related injection nozzles and lances are described which facilitate the merging of the combustion of fossil fuels and separately added solid biomass waste product fuels in the form of pelletized chars and fine particulates. The teachings of this inventor's earlier patent, “Variable Gas Atomization,” U.S. Pat. No. 4,314,670, (referred to herein as VGA) are employed. They are applied in a distinctly different manner so as to enable air conveyed and injected solids to be accelerated, propelled and distributed in the combustion zone of fossil or biomass fuel boilers. While the use of an annular nozzle configuration with conically flared exit tips is generally similar, the functions to be performed, and the related conical exit configuration, differ. An assembly of five concentric, annular tubes and conically shaped exit tips is used to deliver air conveyed biomass fuel as an annular stream between two higher velocity air streams, both of which converge so as to accelerate and propel the biomass fuel, and distribute it into the flame zone produced in a conventional fossil fueled boiler. The additional air required for combustion of the biomass fuel is fed to the expanding plume produced by the fuel delivery stream and adjoining air streams. A portion of the combustion air is delivered through the inside of the inner tube in sufficient volume to provide the entrainment flow produced by the expanding air streams. In so doing, it prevents undesirable recirculation of combustion gases and unburned fuel. The remainder of the combustion air is delivered through an additional annular nozzle located on the opposite side of the expanding streams to similarly mix with the fuel.

摘要:
A system and method for treating, injecting and co-combusting sludge in a municipal waste or other combustor is disclosed. The system includes a sludge receiving and treatment module and a sludge injection and combustion module. The sludge is received and stored in one or more storage hoppers where it is first diluted with a liquid and subsequently mixed to a desired homogeneous consistency suitable for pumping. The high liquid content sludge is then pumped to a furnace injection nozzle where it is preferably atomized with steam and sprayed into the combustion zone of the furnace. The disclosed system and method increases sludge moisture content and controls the solids content of the sludge to control furnace temperature.
