摘要:
A fossil-fuel-fired system, which includes an emissions-control-agent dispenser, a furnace, an emissions monitor and, optionally, a controller, is disclosed. The emissions-control-agent dispenser provides a prescribed amount of organic-emissions-control agent, such as, for example, an opacity-control agent to the fossil-fuel-fired system. The furnace includes an exhaust communicating with the atmosphere. The emissions monitor is capable of measuring at least one property of the flue-gas communicated through the exhaust to the atmosphere. For example, when an organic-emissions-control agent is an opacity-control agent, the emissions monitor has the capability of at least measuring opacity. When included, the controller communicates with at least the emissions-control-agent dispenser and the emissions monitor.

To enable a burnpot for a corn burning stove to be continuously operated, the burnpot has an openable bottom with at least a first and second position, one of said at least fist and second positions being substantially closed to enable a body of combustible fuel to burn on its upper surface, the other of said at least first and second positions providing an opening, burnpot side wall portions and a top of said burnpot being shaped so as to permit a solid clinker to drop out of the opening in the openable bottom when the openable bottom is in its second position. A combustion volume is provided between said openable bottom, said side surfaces and said top, said combustion volume having an upper portion and a lower portion whereby a fire on a combustion surface in said lower portion burns upwardly toward said upper portion so that byproducts of combustion build on the combustion surface to cause burning fuel to burn at a higher level; said higher level having a smaller cross sectional area than said lower portion whereby the byproducts of combustion may drop as a unit out of said opening. A combustion retention openable burnpot bottom to retain combustion in the burnpot when byproduct of combustion is removed through the openable bottom.

In a power generation system biomaterial is grown in a biomass field near a furnace. The plants or oils from the plants are periodically harvested and burned by the furnace to generate steam which runs a generator. Waste heat from the furnace and condenser is collected and returned to the biomass field. The by-products of combustion, principally heat, carbon dioxide, water vapor and ash, are in part cycled back to a biomass field as input energy and nutrients.
摘要:
Solid combustible waste materials are converted into highly efficient fuel by subjecting such materials to size reduction in suitable size-reducing equipment. The last piece of the equipment is a mill which pulverizes the waste materials into fine particles having a high surface to mass ratio and forming a highly efficient fuel when these particles are directly injected into a combustion reactor operating at high temperature.

Systems and methods for pyrolyzing waste materials are described. The method utilizes waste heat from a cement kiln and the pyrolysis system includes at least a feed inerting section and a pyrolysis chamber. The method includes feeding drums of waste into the feed inerting section, replacing oxygen in the feed inerting section with carbon dioxide recovered from the cement kiln, and transporting the drums of waste through the pyrolysis chamber. The waste is pyrolyzed in the pyrolysis chamber with exhaust gasses from the cement kiln and a fuel gas created by the pyrolysis is routed to provide heat to the cement kiln.
摘要:
There is provided a method of incinerating a waste material to process incineration residues produced in a gasification furnace easily with existing equipment. A combustible gas generated when a waste material A is dry-distilled in a gasification furnace 1 is introduced into a combustion furnace 3 and combusted therein. The combustible gas is generated in the gasification furnace 1 in order to keep the temperature in the combustion furnace 3 at a temperature capable of melting incineration residues. The incineration residues are charged into the combustion furnace 3 while the combustible gas is being combusted therein, and melted into a melted material B that is discharged from an outlet 3 of the combustion furnace 3 into a receptacle 33 in which the melted material B is solidified. Air supplied to an air jacket 6 and oxygen supplied to the gasification furnace 1 and the combustion furnace 3 are heated by a heat exchange with waste gases from the combustion furnace 3. The heat exchange is carried out by providing a heat exchanger 36 with a conduit 8 disposed therein in a passage of the waste gases from the combustion furnace 4, and passing air or oxygen through the conduit 8 upstream in the passage of the waste gases.

A system for disposing of municipal solid waste 10) provides commercially-available equipment that is modified to initially remove identifiable unwanted components from the waste (12), and then chop the waste into small pieces (16) of a size suitable for handling and combustion. The moisture content of the waste is reduced in a closed system (20) by passing dry air through the waste in a confined space (30) to absorb moisture and produce moist air, which is then dehumidified via refrigeration equipment (34). The dehumidified air is recycled (30, 40) through the waste repeatedly through the closed system (20) until the water content has reached the predetermined amount. The waste is stored in a bunker (41) for later burning, or is immediately burned in a furnace (24) to produce heat that is used to produce steam (50), which drives a generator (26) to produce electricity (52) that is partly used to power the process and partly sold commercially.

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.

The invention provides a boiler provided with low cost means which can reduce a concentration of CO, an unburned matter, an attached ash and the like near a side wall and maintain a combustion state well with a simple structure. In a boiler having a combustion chamber 13 formed by front and rear walls (burner walls) provided with a plural stages of burners 2, 3 and 4 on at least one of them and opposing to each other, and side walls 1a and 1b crossing to said burner walls 14a and 14b, a gas port 6 containing no fuel for making a pressure of a gas near said side walls 1a and 1b within said combustion chamber 13 higher than a pressure of a gas at a center portion of said combustion chamber 13 is provided between an outermost burner and the side walls 1a and 1b within a range of a height of said burner stages 2, 3 and 4. A combustion gas 16 can not come close to the side walls 1a and 1b due to the jet 18 of the gas.
