Advanced Pulverized Coal Injection Technology and Blast by K. Ishii

By K. Ishii

as a way to lessen the price of working blast furnaces (BFs), injected pulverized coal is used instead of coke to fireside BFs. due to this, unburned fantastic fabrics are blown with the fuel into the bosh and useless guy parts with attainable harmful results on gasoline movement and permeability of the coke column. The potential of the furnace to devour those debris by means of answer loss is maybe one of many obstacles to coal injection. it truly is, for this reason, very important to appreciate the physicochemical and aerodynamic behaviour of fines together with the swap of in-furnace phenomena.

The Committee of Pulverized Coal Combustion and In-Furnace response in BF was once manage in 1993 as a cooperative examine of the Japan Society for the advertising of technological know-how (JSPS) and the Iron and metal Institute (ISIJ) to guage examine initiative into this problem.

This publication experiences at the JSPS/ISIJ Committee's actions and describes the translation of findings drawn from combustion experiments and the result of dwell furnace functions, and furnace functionality.

Perovskite Oxide for Solid Oxide Fuel Cells (Fuel Cells and Hydrogen Energy)

Gasoline phone know-how is kind of promising for conversion of chemical strength of hydrocarbon fuels into electrical energy with out forming air pollution. There are various kinds of gas cells: polymer electrolyte gas telephone (PEFC), phosphoric acid gas phone (PAFC), molten carbonate gasoline cellphone (MCFC), reliable oxide gasoline cellphone (SOFC), and alkaline gasoline phone (AFC).

Oil and Gas Corrosion Prevention: From Surface Facilities to Refineries

In line with NACE (National organization of Corrosion Engineers), the whole annual fee of corrosion in petroleum refining takes up $3. 7 billion within the US by myself. Corrosion keep an eye on is often a problem for the downstream undefined, yet because the caliber of feedstock is declining as a result of refineries accepting extra of the heavy and shale gasoline and oil assets which are extra available this present day, refinery managers, petroleum and typical gasoline engineers are unprepared for the recent set of corrosion difficulties which are exhibiting up of their apparatus and processing devices.
