Description

1.To understand the physics behind pyrolysis and combustion behaviour of TATASTEEL coal tar oil. 2.To model the combustor with realistic boundary and operating conditions. 3.Analyse the various design factors of the induration furnace and burner nozzle. 4.Study the influence of atomising air, primary air, secondary air on flame characteristics.

Problem Statement

A numerical study of combustion of tar-oil in an industrial furnace is carried out to understand the flow, temperature distribution and flame characteristics. The geometry of the furnace with the actual dimensions is modelled and the flame characteristics are studied.

Outcome of the Research

Coal tar pyrolysis data and its combustion characteristics for better utilization of the fuel, have been explained.
Optimization of the combustor design and operating conditions (Temperature, A/F ratio, flame length etc.) for improving the combustion efficiency.
A validated combustion model for existing nozzle design along with relevant FLUENT case and data files delivered to TATA steels.
