Abstract

The invention discloses a side-fired reformer. The side-fired reformer comprises: a radiant section furnace, the radiant section furnace includes: an inlet furnace and an outlet furnace, and a radiation-to-convection hot flue is arranged between the inlet furnace and the outlet furnace; Multiple parallel conversion tubes, each conversion tube includes: inlet conversion tube, outlet conversion tube and flexible middle tail pipe, the inlet conversion tubes are arranged in parallel and vertically in the inlet furnace, and both ends extend out of the inlet furnace; the outlet conversion tubes are parallel and vertically arranged in the outlet furnace Inside, both ends protrude from the outlet furnace; the inlet conversion tube and the outlet conversion tube are connected by a flexible middle tail pipe arranged on the top of the furnace in the radiant section; side wall burners are arranged on the side walls of the inlet furnace and the outlet furnace, The radiant heat supply and the temperature of the furnace tube wall are uniform, and the load of each furnace and the heating load along the length of the furnace tube can be adjusted according to the heating demand. The expansion of the tube system is relatively simple, and the hanging structure is simple, which is convenient for inspection and maintenance.

Description

technical field [0001] The invention relates to the field of petrochemical equipment, in particular to a side-fired reformer. Background technique [0002] At present, reformers such as hydrogen production reformers, CO reformers, and ammonia synthesis reformers are usually used in refining and chemical plants. Multiple reforming tubes are installed in the furnace, and catalysts are installed in the reforming tubes. Each reforming tube is a small reaction. device. Taking the hydrogen production unit as an example, the hydrogen production reformer is the reactor of the conversion reaction in the hydrogen production unit. The reactor is designed in the form of a heating furnace. The catalysts are installed in the reformer tubes and are directly radiated by the burners in the furnace. The reaction medium reacts through the catalyst bed in the furnace tubes. Due to the harsh operating conditions of the reformer, its furnace structure, furnace tube material, furnace tube system...
