The report is focused on the design and thermal performance of the continuous furnace for heating of pipe billets before piercing operating at ‘ChPRP’ PJSC. The problems arising during operation of the thermal generating unit have been analyzed. To evaluate the efficiency of existing heating system, the heat balance of the continuous furnace has been drawn up. During analysis of the results of calculated studies, disadvantages of existing furnace systems and assemblies have been revealed. In order to improve the quality of metal heating, it is proposed to install the through-type furnace heated by means of regenerative burners, as well as provided with the metal transportation system, ensuring more uniform heating, both along the length and thickness of billets, in place of the existing furnace. When implementing the proposed activities, a significant economic benefit is expected, which is confirmed by the heat balance of the through-type furnace given in the article. Besides, to visualize the distribution of temperature and gas-dynamic flows within the operating space of the proposed through-type furnace, the computer simulation for evaluation of the uniformity of metal heating has been performed.
