Additionally, Microbeam also provides Plant Performance Index (PPI) calculations, based on plant operational parameters input and fuel quality. Plant personnel can use this data to optimize boiler operations in order to maintain slag flow, minimize NOx formation, and minimize ash deposition.
Abstract. Integrated gasification combined cycle (IGCC) is a potentially promising clean technology with an inherent advantage of low emissions, since the process removes contaminants before combustion instead of from flue gas after combustion, as in a conventional coal steam plant.

Power plants burning anything other than natural gas will, over time, build up ash that forms slag deposits on the exterior of the tubes running through the boiler.
Coal bottom ash and boiler slag are the coarse, granular, incombustible by-products that are collected from the bottom of furnaces that burn coal for the generation of steam, the production of electric power, or both. The majority of these coal by-products are produced at coal-fired electric utility ...
The Shell Coal Gasification Process (SCGP) is a dry-feed. oxygen-blown, entrained flow coal gasification process which has the capability to convert virtually any coal or petroleum coke into a clean medium Btu synthesis gas, or syngas.

In entrained-flow gasifiers, fine coal feed and the oxidant (air or oxygen) and/or steam are fed co-currently to the gasifier.This results in the oxidant and steam surrounding or entraining the coal particles as they flow through the gasifier in a dense cloud.
The physical properties of coal bottom ash and boiler slag vary depending on the type, source, and fineness of the parent fuel, as well as the operating conditions of the power plant.
Slag is molten ash and incombustible byproducts that remain following coal combustion. When the material cools to a certain temperature, it can stick to furnace components, such as waterwalls ...

Seggiani developed a simplified model for the simulation of time-varying slag flow in an entrained flow reactor of the IGCC Power plant, Spain. The furnace was operated at 25 bar supplied with coal and limestone mixtures as fuel.
Accurate modeling of coal ash slag viscosity as a function of temperature, including the transition from Newtonian to non-Newtonian flow, is essential to successful slag management for coal gasification.
Moving thousands of tons of coal per hour at high speeds through a complex handling system is a main cause of airborne coal dust in a coal-fired plant. Depending upon the coal's characteristics ...
Chemical products production in coal tar treatment plant Coal tar is a dark viscous material obtained as a by-product during the process of destructive distillation of coal (to produce coke oven gas and coke).
This report also discusses the effects of coal ash and slag properties on slag flow and its qualities required for the entrained flow gasifier. Finally this report will identify the key operating conditions affecting slag flow behaviors, including temperature, oxygen/coal ratio, and flux agents.
Slag flow is controlled by the viscosity of the slag, which in turn depends on the slag temperature and slag chemical composition. So changes in the coal result in
In the present work, the literature on slag flow modeling was reviewed and a model similar to Seggiani's was developed to simulate the time varying slag accumulation and flow on the walls of a Prenflo coal …

Get More Info Cyclone furnace A cyclone furnace is a type of coal combustor commonly used in large industrial boilers, A layer of molten slag coats the burner and flows .
The pulverized coal-fired wet-bottom unit traps 50% or less of the ash as molten slag on the furnace walls; this slag runs down to the furnace floor and taps down into the slag tanks for removal. Cyclone furnace boilers are the wet-bottom type because they make slag that flows out on the furnace walls, then to the floor, and into slag tanks.
