The Design of Gas Chamber Heating Furnace
Abstract: This design is designed for the design of a new gas chamber furnace, mainly to determine the basic size of the furnace, the design of the fuel and exhaust system.The co- ncrete steps are the calculation of fuel combustion, he determination of the heating syste- m, the determination of the heating time of the billet, the determination of the basic size of the furnace, the calculation of the heat balance and the determination of the fuel consu- mption. Selection of burners, design of flue, chimney design, heat exchanger design,pipi- ng calculation, and final fan selection. The furnace adopts the standard three stage heatin- g method, one section of the preheating section, one section of the heating section, and one section of the heating section.Furnace gas is used as fuel for walking beam reheating furnace. In the design of the smoke exhaust system, the design of the flue size and the ca- lculation of the resistance of the flue are mainly carried out, then the height of the chimn- ey is determined, and then the model of the fan is determined by the design of the pipe and the related calculation. As a matter of course, walking beam reheating furnace has many advantages, such as low heat consumption, high yield and strong applicability.
