Estimation of Burning Rates in Solid Waste Combustion Furnace

The author provides an interesting one-dimensional ap­ plication of Essenhigh's bed combustion models to munici­ pal waste combustors. Some of the model's limitations are recognized when the author explains that this work only considers chemical heat release and that radiative and con­ vective heat release may be significant and should be con­ sidered as well. In the mid 1970s, I was part of a ...

Study on Combustion Characteristics of the Blast Furnace Gas in the Constant Volume Combustion Bomb

Blast furnace gas is the byproduct of smelting steel production process, and is the important secondary energy source. It is can be used as fuel for engines to generate electricity for most middle and small steel enterprises. In order to understand the combustion mechanism and provide the basis for the design of blast furnace gas engine,premixed laminar combustion experiments of the blast furna...

Blast Furnace Granular Coal Injection System Demonstration Project

The Clean Coal Technology (CCT) Demonstration Program is a government and industry co-funded effort to demonstrate a new generation of innovative coal utilization processes in a series of " showcase " facilities built across the country. These projects are carried out on a sufficiently large scale to prove commercial worthiness and generate data for design, construction, operation, and technica...

Injection of coal and waste plastics in blast furnaces

The majority of waste plastics currently produced are either landfilled or incinerated. Plastics do not readily degrade and toxic elements can be leached from the landfill. Combustion of waste plastics can generate environmentally hazardous air pollutants such as dioxins/furans, as well as undesirable carbon dioxide. Consequently, cost effective ways of recycling the increasing amounts of gener...
