Overview of reforming furnace
Catalytic reforming is an important part of refining process, mainly to improve the quality of oil, the reaction of reforming furnace provides heat, reforming furnace has side burning square box furnace and bottom burning reformer, reformer is now mostly combined reforming, furnace tube temperature in 210 ℃ or so, furnace temperature in 900 ℃.
Heat insulation structure of catalytic reform heating furnace
Taking the radiant section of side-fired reforming furnace as an example, the partition insulation structure of ceramic fiber lining is introduced;
Roof insulation of radiation chamber of catalytic reforming furnace;
Lining thickness: 280 / 300 mm
Lining structure: 250 mm 1400 type low zirconium ceramic fiber module + 30 / 50 mm 1260 type common ceramic fiber felt or blanket
Anchoring material: s304 stainless steel
Heat preservation of upper and middle wall of catalytic reforming furnace;
Lining thickness: 250 - 270 mm
Lining structure: 220 mm 1400 type low zirconium ceramic fiber module + 30 / 50 mm 1260 type common ceramic fiber felt or blanket
Anchoring material: s304 stainless steel
Catalytic reforming furnace radiation section of the lower side wall ( 7 meters above the bottom of the furnace burner parts ) heat preservation:
Lining thickness: 300 mm
Lining structure: 250 mm 1400 type low zirconium ceramic fiber module + 50 mm 1260 type common ceramic fiber felt or blanket
Anchoring material: s310 stainless steel
Advantages of refractory fiber lining or construction technology of Jinshi thermal ceramic;
Stable chemical performance: the chemical performance of ceramic fiber lining is stable, except phosphoric acid, hydrofluoric acid and strong alkali, other acids, alkali and water, oil and steam are not eroded, and lead, aluminum and copper are not infiltrated.
No oven: no oven procedures ( e.g. maintenance, drying, baking, complex oven process and protective measures in cold weather ) are required. the furnace lining can be put into use after construction, saving time and cost.
Advantages of production process: fiber blanket products adopt the production process of self - melting, continuous melting and continuous throwing of unlined water wall, and double-sided needling forming. The fiber module has the advantages of long fiber length, uniform diameter, high tensile strength, large expansion rate, strong airflow erosion resistance and good thermal stability. The fully automatic heating furnace blanket heat treatment system can pre-treat the phase change of the fiber products and greatly reduce the high-temperature shrinkage of the products in the use process.
