Abstract

The invention relates to a novel tubular preheater for a carbon dioxide testbed and a preheating method. As a result of increasingly competitive market competition and increasingly improvement of arrangement forms of boilers, original channel equipment cannot achieve horizontal flowing heat exchange of flue gas and air. The preheater comprises a middle tube bundle (1) which comprises front and back tube plates (3). Each tube plate is provided with a horizontal round hole and is vertically mounted on a sliding base plate (6), a tube (4) is threaded in the horizontal round holes between the front and back tube plates, steel flat (7) is separately fixed above and below the middle tube bundle, the upper and lower sides of the tube plate are separately fixed to an upper protecting plate (2) anda lower protecting plate (5), an air duct communicating box A (10) is mounted on one side of the middle tube bundle and an air duct communicating box B (13) is mounted on the other side of the middletube bundle. The invention provides the novel tubular preheater for the carbon dioxide testbed.

Description

[0001] Technical field: [0002] The invention relates to a novel tubular preheater and a preheating method for a carbon dioxide test bench. [0003] Background technique: [0004] Due to the increasingly fierce market competition and the increasingly perfect layout of boilers, the original tube and box equipment cannot realize the horizontal flow and heat exchange of flue gas and air. [0005] Invention content: [0006] The purpose of the present invention is to provide a new type of tube preheating and preheating method for carbon dioxide test bench. [0007] Above-mentioned purpose realizes by following technical scheme: [0008] A new tubular preheater for a carbon dioxide test bench, which consists of: an intermediate tube bundle, the intermediate tube bundle includes two front and rear tube plates, and the tube plate has a group of horizontal round holes and is vertically installed on the On the sliding backing plate, pipes are pierced in the horizontal round holes be...
