Abstract
A heating furnace body of a hydrogen generation device by ammonia decomposition includes a furnace chamber (2) enclosed by heat-resistant bricks (1), a furnace pipe (3) which is arranged in the furnace chamber (2), electric heating boards (5) which are positioned at four side wall parts of the furnace chamber (2), an electric resistance wire (4) is arranged in electric heating board (5) at each side, the electric resistance wire (4) which is arranged in the electric heating board (5) at each side is connected by a plurality of wires in series, and each electric resistance wire is arranged in a straight electric resistance wire slot (9) in each electric heating board (5). As the electric resistance wire at each side is composed of a plurality of wires, the utility model can carry out the separate replacement of one damaged electric resistance wire, so the length of the replaced electric resistance wire is smaller. The electric resistance wires can be pulled out from the straight electric resistance wire slots, so the electric heating board parts do not need to be replaced during the replacement of the electric resistance wires and the replacement cost is low.
Description
Technical field
The utility model relates to a kind of preparing hydrogen by ammonia decomposition unit furnace body.
Background technology
Preparing hydrogen by ammonia decomposition unit furnace body of the prior art as accompanying drawing 1 to shown in the accompanying drawing 3, comprise the burner hearth that surrounds by heat resisting brick, be arranged at flue in the described burner hearth, be arranged at catalyst in the flue, be positioned at the hot plate of four side wall portions of burner hearth, be provided with the cavity that resistance wire is used for heating furnace in described every side hot plate, flue also is provided with inlet pipe and escape pipe.Resistance wire on the hot plate of each side wall portion is a whole resistance wire, resistance wire is a consumable accessory, because resistance wire is coiled on the hot plate, therefore need extract out together with hot plate after the somewhere resistance wire disconnects and change, cause the cost changed to improve, and resistance wire is coiled in and make on the hot plate that to wear resistance wire on hot plate pretty troublesome.
Summary of the invention
The purpose of this utility model is to provide a kind of replacing resistance wire preparing hydrogen by ammonia decomposition unit furnace body simply and easily.
The technical solution of the utility model is: a kind of preparing hydrogen by ammonia decomposition unit furnace body, comprise the burner hearth that surrounds by heat resisting brick, be arranged at flue in the described burner hearth, be positioned at the hot plate of four side wall portions of burner hearth, be provided with resistance wire in described every side hot plate, resistance wire in described every side hot plate is in series by many, and every resistance wire is arranged in the interior straight resistance wire groove of hot plate.
The utility model compared with prior art has following advantage:
Because the resistance wire of every side is formed by many, therefore can change separately with regard to a resistance wire that damages, the resistance wire length of being changed is little.Resistance wire can directly be extracted out in straight resistance wire groove, does not need to change the hot plate part when therefore changing resistance wire, and the cost of replacing is low.
