Flame linkage system of fuel gas radiation pipes

Abstract

The invention provides a flame linkage system of fuel gas radiation pipes. The flame linkage system comprises the multiple radiation pipes and a plurality of flame linkage devices. At least one flame linkage device is arranged between every two adjacent radiation pipes. Each flame linkage device comprises two channels arranged in a crossed manner, wherein the first channel is provided with a first high-temperature smoke inlet and a first high-temperature smoke outlet, the first high-temperature smoke inlet is connected with the corresponding ignited radiation pipe, the first high-temperature smoke outlet is connected with the corresponding adjacent radiation pipe, and the included angle is formed between the first channel and the second channel. The flame linkage system is simple in structure and convenient to operate, the control system cost and work intensity are reduced, a radiation pipe combustor ignition system is simplified, and burner producing and running cost is reduced to the great degree. Meanwhile, the combustion system is stable, and the phenomenon that due to instable ignition burner flame monitoring signals at present, a fuel gas valve is frequently cut off cannot occur.

Description

technical field [0001] The invention belongs to the field of gas heat storage combustion equipment, and in particular relates to a gas radiant tube combustion system with a co-flame device. Background technique [0002] The gas radiant tube mainly uses coal gas as fuel, burns in a special sealed casing, and transfers heat to the heated object in the form of heat radiation through the heated casing surface, and the combustion product does not contact the heated object; regenerative gas The radiant tube uses the sensible heat of the flue gas after combustion in the casing to preheat the combustion air or gas through the arrangement of the regenerator. It has the characteristics of high combustion thermal efficiency, stable operation, and high equipment reliability. It is widely used in various heat treatment furnaces and continuous annealing furnaces. stove etc. [0003] Due to the normal working process of the gas radiant tube, it is necessary to configure the corresponding ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention designs and develops a gas radiant tube combustion system with a cross-flame device, which solves the problem that the current gas radiant tube needs to be equipped with a large number of ignition burners and corresponding ignition control systems. The system is very large and requires manual operation. Technical issues such as cumbersome and high cost
