Abstracts: In a as fired furnace operating and maintenance cost is very high. So instead of using gas fired furnace gas fired furnace is designed, which reduces the operating and maintenance cost.It also improves furnace furnace efficiency and capacity. Also loss of heat due to incomplete combustion of fuel takes place , which is not an issue in this case. Also life of furnace is observed to improve.
