ABSTRACT

In this paper, Baogang Hot MILL 180 t / h for Regenerative furnace requirements of a graduation project Reference has been in the literature on the basis of blast furnace gas to fuel the furnace design a comprehensive thermal calculation。Including combustion, the heating time, the metal structure, masonry design, heat balance calculation. In the projector adumbrate the blast and the air at the same time,not only improve the thermal efficiency,but efficiedcly make use of the blast furnace gas.Focus on the selection process heating furnace, the heating time and load calculation of changes in how the changes in operating parameters were studied and discussed, the furnace important supplementary equipment selection, concluded that the design and the work of the next step Their ideas and perspectives.Through this graduate design and improve regenerative combustion technology, to improve the thermal efficiency of the stove, the goal of improving product quality, while using the stove vaporization cooling system, reducing the water pipes and India to ensure heating quality.

Because the design adopted the high temperature air combustion technology,

it owned the various advantage, particularly at economized on energy to decline to consume and environmental protection to obtain the very big result， we believed that it will own vast development foreground in the domestic。

Keywords:furnace，blast furnace gas，regenerative comb ustion，high efficiency and energy saving
