Gas well structure for electrode roasting furnace

Abstract

The invention discloses an electrode roasting furnace in the field of graphite electrode production, in particular to a gas well structure for an electrode roasting furnace. The gas well structure is characterized in that a gas well building body is built by gas well shaped bricks, a gas well mouth is arranged at the top of the gas well and a combustion-supporting air inlet opening is arranged at the upper part of the gas well. The gas well has good integrity; because a plurality of dilatation joint structures are arranged in the gas well building body, the gas well building body has good swelling stress absorption property; the gas well ensures the reliable deformation resistance when being taken as the combustion space and sufficient combustion-supporting air enters during the fuel combustion to achieve the purpose of complete combustion and improves the utilization ratio of fuel and reduces the energy consumption; the gas well keeps the cross section basically unchanged, is favorable for keeping the reasonable distribution of the negative pressure in the flame system and the smooth smoke flowing and effectively ensures the compliance between the furnace temperature distribution and the baking curve and the quality of the baked products; and the gas well can effectively ensure the capability of the main smoke extraction system to provide the negative pressure to the electrode roasting furnace.

Description

technical field [0001] The invention relates to an electrode roasting furnace in the field of graphite electrode production, in particular to a fire well structure of an electrode roasting furnace, which is used to solve the problems of unreasonable structure, poor strength, easy deformation, easy collapse at high temperature, and increase in electrode roasting furnace fire well structure. The loss of flow resistance of the flue gas in the roaster caused the problem that the electrode roaster entered the overhaul in advance. Background technique [0002] The fire well is an important structure that makes up the furnace chamber of the electrode roaster. As the combustion space of the heating furnace chamber, it is the part that bears the highest local temperature during the operation of the electrode roaster, and is also the main channel for the flue gas flow in the flame system of the electrode roaster , it also has to withstand the high-speed erosion of high-temperature flu...
