Rethinking required in High Fuel cost era on need of Burners and Combustion system for the reheat furnaces for small and Medium Rolling mills using Lean fuels (PG/BFG) & Rich Fuels (Heavy Oil or NG) in Combination Firing

摘要

The fuel costs are rising at much faster rate at this moment and it's already at peak and threatening to break records in near future. Though coal costs are also rising still use of Producer gas as Industrial fuel is becoming very popular in coal belt of India. There many plants in India where they have small and Medium Blast furnaces and their power plant projects have not come up to use BFG as fuels and hence they are Flaring the gas. Let's look at what Customer (user) of Reheat furnace wants for smother operation. 1. Uniform Soaking so that the rolling mill has no trouble and can ramp up production to its maximum capacity at a short notice. 2. Less scale loss. 3. Reliability 4. Fuel Economy. 5. Fuel flexibility when any one of the fuel is not available.
