Blast Furnace Gas, its Characteristics and Safety

The lower heating value (also known as net calo-rific value, NCV, or LHV) of the COG is approximately 4131 kcal/ Nm3. BFG is a by-product of the iron making process, where iron ore, coke, and limestone are heated and melted in a blast furnace. Car-bon monoxide produced from the burning of the coke reacts with the iron ore, reducing it to iron.

PROBLEMS ASSOCIATED WITH COMBUSTION OF BLAST …

The blast-furnace gas is a low-grade producer gas, made by the partial combustion of the coke used in the furnace and modified by the partial reduction of iron ore. The gas contains more carbon dioxide and less hydrogen than normal producer gas made from coke, and also has a lower calorific value.

Blast Furnace gas generation and usage – IspatGuru

Jul 01, 2011 · In this study, the combustion characteristics of firing blast furnace gas (BFG) individually or in combination with coke oven gas (COG) were investigated theoretically and experimentally. The theoretical results showed that at the same heat release rate under the operating conditions of stoichiometry, firing BFG individually had a greater amount of fuel gas volume flow rate, a smaller amount of air volume flow rate, and a lower …

Leak detection in a subcritical boiler (Journal Article

Nov 27, 2020 · Thermal power plants experience cycling duty leading to the fatigue of the boiler and heat exchanger tubes. As a result, tube failures occur frequently in coal fired fleets leading to forced outages. Furthermore, because the tube leaks have been the major source of unwanted shutdowns and the number of outages is increasing, present work focuses on the detection and isolation of the leak in a subcritical boiler …
