US Classification:

122149, 122 75, 122 76

Abstract:

A firetube boiler furnace having two combustion sections and an in-line intermediate tubular heat transfer section between the two combustion sections and integral to the pressure vessel. This design provides a staged oxidant combustion apparatus with separate in-line combustion chambers for fuel-rich primary combustion and fuel-lean secondary combustion and sufficient cooling of the combustion products from the primary combustion such that when the secondary combustion oxidant is added in the secondary combustion stage, the NOformation is less than 5 ppmv at 3% O.

Appl. No.:

8/382191

Inventors:

Jacob Korenberg - York PA

Assignee:

Donlee Technologies, Inc. - York PA

International Classification:

F28D 1300

US Classification:

16510416

Abstract:

The heat exchanger includes a hot fluid passage for guiding hot fluid through the heat exchanger, a compartment for containing a fluidized bed, a series of nozzles for forcing particulates from the fluidized bed into the hot fluid, a heat transfer device in contact with the fluidized bed, means for separating particulates from the fluid that has passed through the hot fluid passage, and a return passage for returning separated particulates to the fluidized bed in the compartment. The fluid is guided over the upper surface of the fluidized bed. Air is blown through the series of nozzles to force particulates from the fluidized bed into the fluid in the hot fluid passage where they pick up heat from the fluid, and the particulates then fall back into the bed and transfer heat to the fluidized bed. The heat transfer device removes heat from the fluidized bed and transfers it to a working fluid without being in contact with the hot fluid passage.

US Classification:

122136R

Abstract:

A cyclone combustion apparatus includes a combustion chamber having a substantially cylindrical wall, a substantially cylindrical exit throat at the rear end of the combustion chamber, means for supplying partially preburned fuel into the combustion chamber at a front end thereof, means for supplying secondary air into the combustion chamber and for forming a cyclonic flow pattern of hot gases for combustion within the chamber, and heat exchange means surrounding and extending throughout the axial length of the combustion chamber. The apparatus may also include a substantially cylindrical cooling chamber extending beyond the exit throat from the rear end of the combustion chamber and substantially longitudinally aligned with the combustion chamber. The combustion chamber, the exit throat and the annular secondary air supply opening are dimensioned and configured to effect a cyclonic flow pattern in the combustion chamber.

International Classification:

F23D 1400
F23G 500

US Classification:

110346

Abstract:

An incineration apparatus and method for disposal of infectious hazardous waste including a fluidized bed reactor containing a bed of granular material. The reactor includes a first chamber, a second chamber, and a vertical partition separating the first and second chambers. A pressurized stream of air is supplied to the reactor at a sufficient velocity to fluidize the granular material in both the first and second chambers. Waste materials to be incinerated are fed into the first chamber of the fluidized bed, the fine waste materials being initially incinerated in the first chamber and subsequently circulated over the partition to the second chamber wherein further incineration occurs. Coarse waste materials are removed from the first chamber, comminuted, and recirculated to the second chamber for further incineration. Any partially incinerated waste materials and ash from the bottom of the second chamber are removed and recirculated to the second chamber for further incineration.

International Classification:

F22B 712

US Classification:

122149

Abstract:

A boiler with a cyclonic combustor includes a first chamber which is substantially uncooled and refractory lined, a second chamber in fluid communication with the first chamber, ducts for supplying air and fuel directly into the first chamber and for forming a cyclonic flow pattern of hot gases for combustion within the first and second chambers, an exit throat at the end of the second chamber and a heat exchanger surrounding the second chamber for keeping low combustion temperature in both chambers.

Appl. No.:

7/664288

Inventors:

Jacob Korenberg - York PA

Assignee:

Donlee Technologies, Inc. - York PA

International Classification:

F02G 300

US Classification:

60 3905

Abstract:

A staged combustion apparatus for a gas turbine to lower the concentration of NO. sub. x and CO in the exhaust gases. Combustion occurs in a first and second stage, the first stage being sub-stoichiometric combustion and the second stage being above-stoichiometric combustion. Cyclonic combustion occurs in one of the first and second combustion stages and a swirling pattern of combustion occurs in the other of the combustion stages. Steam injection is provided to further lower the concentration of NO. sub. x in the exhaust emissions from the gas turbine.

Abstract:

A gas turbine cycle in which air is compressed to superatmospheric pressure, water is circulated in heat exchange relation with the compressed air to convert the sensible heat therein to heated water, the compressed air is humidified using the heated water, the humidified air is heated with sensible heat in the turbine exhaust gases, and a solid fuel such as coal is converted to a motive fluid for driving the gas turbine by substoichiometrically burning solid fuel under superatmospheric pressure using oxygen from the heated humidified air for combustion of the solid fuel and to produce combustible fuel gas and char, above stoichiometrically and adiabatically burning the char under superatmospheric pressure by supplying the heated humidified air in sufficient quantity to provide oxygen for combustion of the char and to control the temperature of such combustion, thereby to produce char combustion gases containing oxygen, cleaning the combustible fuel gas and the char combustion gasses to remove particulate materials therefrom, and burning the combustible fuel gas under superatmospheric pressure, oxygen for combustion of the gases being supplied by the char combustion gases and the heated humidified air, and the temperature of such gas combustion being controlled by the quantity of heated humidified air supplied for burning the fuel gas and the char combustion gases, the products of such gas combustion providing the motive fluid for driving the turbine.
