Abstract

A modified design of radiation furnace has been presented in which material is heated by flame directly impinging on it. In the existing furnace, the flame produced with gas fired burner (LPG/air) has been used to heat the material and avoid direct contact of flame with the material. Problems such as production lagging, greater fuel consumption, more furnace starting time, lower thermal performance, etc. were occurred in the existing design. In this study, an attempt has been made to improve the performance of the furnace with designing and arranging of burner’s location with respect to target surface. An array of combine swirl and axial flames directly impinging on the surface has been purposed to have got a uniform heat flux distribution over the surface of the material. Consequences such as uniform heating, faster production, significant reduction in fuel consumption and furnace restarting time, hardly any chamber’s constructional and maintenance costs were observed with the use of modified design. With the implementation of modified design, quantitative values of fuel consumption and time to heat one kg material were reduced up to 72.43% and 32.38% respectively. Similarly, furnace restarting time and refractory material for constructing the chamber were significantly reduced. Thermal performance and heat transferring rate were improved up to 1.66 and 0.7275-time exiting values, respectively with an exploration of furnace and burner design.
