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.

Steam Generation System Having Multiple Combustion Chambers and Dry Flue Gas Cleaning

Номер: US20120042810A1

Автор: Tidjani Niass

Принадлежит: Saudi Arabian Oil Co

A method for producing steam while concurrently reducing emissions. The method includes combusting fuel and an oxidant stream having a high concentration of oxygen in a combustion zone having multiple combustion chambers and heat exchangers to produce a flue gas. The flue gas is subsequently cleaned in a dry flue gas cleaning chamber by contacting it with a dry adsorbent. In one embodiment, the method advantageously regenerates the dry adsorbent so that the dry adsorbent can be subsequently recycled back into the dry gas flue chamber.

The present invention relates to a means and method for at least injecting mitigant particles into the combustion region (fireball) of a biomass boiler. The mitigant particles mitigate the slagging, fouling and corrosion problems caused by biomass ash by at least capturing the biomass ash. The mitigant particles capture the biomass ash by forming a physical bond with the biomass ash such that it adheres to the surface of mitigant particles. By injecting the mitigant particles into the combustion region, the opportunity to capture biomass ash is optimised.

A process is described, as well as a plant, for treating a raw vent gas () containing bitumen vapours and released by a piece of equipment () of a polymer-bitumen membranes production line, in which operations are carried out involving a filler powder (), such as an operation of mixing the filler powder () with the bitumen (), during which the raw vent gas () is changed from a substantially powder-free raw vent gas (), into a raw vent gas () containing the filler powder (). The process includes steps of first conveying the raw vent gas () into a gas-washing device () along with a solution () of a surfactant; contacting the raw vent gas () with the solution () and removing the powder from the powder-containing gas (), releasing a purified vent gas () that is substantially free from the filler powder; conveying the purified vent gas () into a boiler () and burning the bitumen vapours. In a preferred exemplary embodiment, it is conveyed in the gas-washing device only the powder-containing gas () produced during the operations of the piece of equipment () that involve the filler powder (), while in the remainder steps the substantially powder-free raw vent gas () is directly conveyed into the boiler () by a direct vent line () that can be automatically selected. In a preferred exemplary embodiment, the gas-washing device comprises a tank () configured to form inside a predetermined head of the washing solution () and having an inlet port for the raw vent gas arranged below the liquid head.
