“…The small to medium businesses keep conventional technology for a production system which mainly due to cost reasons, including furnace technology for oven briquette production [2][3][4], which is relevant to this work. Some others also combine the conventional one and add some optimization in terms of structure and thermal efficiency [5], control system [6], design and analysis [7][8][9], and energy-saving production planning [10]. The main results of previous research activity are to enhance the furnace performance in terms of energy efficiency.…”

The heat transfer system of the pipe for furnace application was newly introduced and need to be analyzed. The study aims to numerically model and investigate the externally blown heated pipe for furnace. The furnace itself is the heat source for briquette production inside the oven. The investigation includes the analysis of temperature, air flow velocity and also pressure inside the pipes. The investigation employed the Computational Fluid Dynamics methodology for numerically analysis the intended results. Three cases were introduced in this study, having differences in the air intake velocity which was set to 5 m/s (case 1), 3 m/s (case 2) and 1 m/s (case 3). The main objective is to have the highest outlet temperature to be blown in the heating chamber. Case 1 results in the lowest resulting temperature which only 77 , while case 3 yields in the highest output temperature more than 100 . In terms of velocity, it is clear that the highest velocity intake affects also in the increasing value of the velocity inside the pipe. Case 1 results in maximum of 35 m/s air velocity. The pressure distribution also results in the similar trend. The case 1 yields in the maximum pressure of 650 Pa and case 3 produce the pressure nearly zero. However, case 3 results in the highest temperature for furnace to be blown in the heating chamber of the oven system.
