Burnout of residual carbon in coal fly ash using air cyclones

Номер: US20120028200A1
Автор: James Kenneth Hicks
Принадлежит: Individual

This patent application is for the novel utilization of an air cyclone combustion unit (CCU) for burnout of residual carbon from burning of fly ash resulting from coal and/or coke in electric power plants or from natural pozzolans. In some cases, residual carbon and/or moisture is too high in fly ash or pozzolans to meet market conditions for quality or ASTM C 618 Specification for Natural Pozzolans and Coal Fly Ash. Heat treating the coal fly ash or natural pozzolan to remove sufficient amounts of carbon renders the remaining pozzolan capable of meeting specifications and being sufficient in quality to perform as a cementitious material in concrete and mortars. Use of an air cyclone, with suitable mechanical adjustments and heat either from an external source or with the inherent heat value from the residual carbon will be claimed.

Burner system for waste plastic fuel

Номер: US20120318180A1
Автор: Thomas Anthony Patti PATERNOSTRO, William Hunkyun Bang
Принадлежит: Individual

The present invention provides a burner system which uses waste fuels, especially waste plastic fuels. Burner size is minimized by having multiple combustion chambers concentrically located around a rotating screw conveyor. Heat efficiency is improved by having air passages disposed around the combustion chambers, thus preheating air for the combustion prior to its delivery to the combustion chambers, while simultaneously thermally insulating the combustion chambers against the environment. Waste fuel is transported from a fuel hopper to the combustion chambers by a rotating screw conveyor having the spiraling auger blades. Speed of screw conveyor rotation controls the consumption of waste fuel and, thus, the amount of thermal energy generated in the burner. The burner system includes an intelligent control system for controlling operation of the burner system, so that the burner system performs at optimum efficiency, safely and with minimum operator intervention.

Combustion monitoring

Номер: US20160076769A1
Автор: Duncan Michael PRICE, Gareth David Stanton
Принадлежит: Edwards Ltd

A radiant burner and method are disclosed. The radiant burner is for treating an effluent gas stream from a manufacturing process tool and comprises: a combustion chamber having a porous sleeve through which combustion materials pass for combustion proximate to a combustion surface of the porous sleeve; a combustion characteristic monitor operable to determine combustion performance of the radiant burner by monitoring infra-red radiation emitted from the combustion surface; and a radiant burner controller operable to control operation of the radiant burner in dependence upon combustion performance determined by the combustion characteristic monitor. Accordingly, aspects recognise that if a burner is suffering from an excessive flow of air the burner pad or combustion surface will typically cool, which results in an increase in unwanted emissions in the exhaust produced by a radiant burner. The cooling also results in a reduction in infrared radiation determined by the combustion surface. The hydrogen flame of the radiant burner and the hydrocarbon flame of the burner pilot typically do not emit infrared radiation and thus a change in infra-red an radiation, for example, intensity, quantity or frequency, emitted by the combustion surface of the radiant burner can be used to diagnose an “overflow” of cold gas, typically air, in the combustion mixture fed into the system, for example, the combustion chamber. Once diagnosed appropriate ameliorative steps may be taken and, for example, the burner control logic may be operable to compensate by reducing air flow into the burner.

METHOD AND APPARATUS FOR THE IMPROVED COMBUSTION OF BIOMASS FUELS

Номер: US20180156453A1
Автор: Higgins Daniel R., Sullivan Eugene
Принадлежит:

A cylindrical furnace having a vertical axis controls combustion. Solid fuel, particulates, and gases inside the furnace rotate around the axis, inducing radial stratification using centrifugal forces. Fuel and particulates drag on the wall of the cylinder, slipping in and out of suspension, thereby increasing particle residence times. The solid particles comprise combustible fuel particles, and non-combustible ash and contaminants. Control of the temperature of non-combustible particles and the wall surface prevents these non-combustible particles from adhering to, and building up on, the furnace wall. It is also advantageous to control the gas temperature leaving the furnace to minimize temperature-driven corrosion of downstream heat-exchange surfaces.

SYSTEM AND METHOD FOR BIOMASS COMBUSTION

Номер: US20210190311A1

Принадлежит:

Disclosed is a system and method for the combustion of biomass material employing a swirling fluidized bed combustion (SFBC) chamber, and preferably a second stage combustion carried out in a cyclone separator. In the combustion chamber, primary air is introduced from a bottom air box that fluidizes the bed material and fuel, and staged secondary air is introduced in the tangential direction and at varied vertical positions in the combustion chamber so as to cause the materials in the combustion chamber (i.e., the mixture of air and particles) to swirl. The secondary air injection can have a significant effect on the air-fuel particle flow in the combustion chamber, and more particularly strengthens the swirling flow, promotes axial recirculation, increases particle mass fluxes in the combustion chamber, and retains more fuel particles in the combustion chamber. This process increases the residence time of the particle flow. The turbulent flow of the fuel particles and air is well mixed and mostly burned in the combustion chamber, with any unburned waste and particles being directed to the cyclone separator, where such unburned waste and particles are burned completely, and flying ash is divided and collected in a container connected to the cyclone separator, while dioxin production is significantly minimized if not altogether eliminated. A Stirling engine along with cooling system and engine control box is integrated with the SFBC chamber to produce electricity from the waste combustion process. Residual heat in the flue gas may be captured after the combustion chamber and directed to a fuel feeder to first dry the biomass. System exhaust is directed to a twisted tube-based shell and tube heat exchanger (STHE) and may produce hot water for space heating. 1. A system for fluidized bed combustion , comprising: a primary air distribution and delivery system configured to provide vertical airflow through said combustion chamber; and', 'a secondary air distribution and ...
