Fuel oil gasification furnace

Abstract

The invention relates to a device for petrochemical production equipment, in particular to a fuel oil gasification furnace. The fuel oil gasification furnace is characterized in that: a furnace lining on a cylinder part of the gasification furnace is provided with a zirconium-containing fiber blanket layer, a light high-aluminum heat insulating brick layer, a zirconium-containing ceramic fiber paper layer and a high-purity low-silicon corundum brick layer which are arranged in turn from a shell, wherein the high-purity low-silicon corundum brick layer is used as a fire facing surface of the gasification furnace. The gasification furnace has the advantages of improving the sealing property of the furnace lining at the fire facing surface, enhancing the sealing property and the heat preservation performance of the furnace lining at the heat insulating layer, reducing the temperature of the furnace wall, eliminating axial thermal expansion stress and radial thermal expansion stress in the furnace lining, preventing frictional shearing force from being produced due to different thermal expansion rates, keeping each layer of the lining to be free from the restriction to independently and freely expand, greatly reducing the damage to the furnace lining, relieving the stripping phenomenon of the lining, maintaining the temperature of the furnace wall to be below 150 DEG C, producing no blow-by and leakage, greatly improving the operating environment, ensuring the production safety, having a long service cycle, reducing the overhauling and maintenance cost and obviously improving the productivity.

Description

technical field [0001] The invention relates to equipment for petrochemical production equipment. Background technique [0002] The synthesis gas unit adopts the process technology of partial oxidation of Shell residual oil to produce CO and H 2 raw material gas as the main component. After desulfurization and decarbonization, this raw material gas can be used as oxo gas to become the raw material for the production of butanol products; 2 The raw material gas as the main component can produce hydrogen through medium and low temperature shift, secondary decarburization, methanation, and hydrogenation of cobalt and molybdenum, and can be used as raw material for synthetic ammonia production equipment, etc. The gasifier is one of the key equipment in the synthesis gas plant. However, due to problems in the lining technology and application of refractory materials in the gasification furnace, the temperature of the furnace wall is extremely high, which can reach above 230 ° C...

Problems solved by technology

However, due to problems in the lining technology and the application of refractory materials in the gasification furnace, the temperature of the furnace wall is extremely high, which can reach above 230 ° C. In addition, the lining of the furnace brick is easy to fall off, resulting in gas blow-by in the lining, and the production has to be stopped for maintenance, which affects the normal operation of the device. operation, also due to the involvement of CO and H 2 How to ensure the safe production of this flammable and explosive medium is of great importance
