Abstract
The invention relates to a reforming furnace with a central burner nozzle. The reforming furnace with the central burner nozzle comprises the central burner nozzle, a furnace head part, a combustion part, a catalytic conversion part and a converter outlet part. The central metal burner nozzle comprises an oxygen-steam inlet pipeline a, a cooling water inlet channel b and a cooling water outlet channel, wherein the cooling water inlet channel b and the cooling water outlet channel are arranged on a pipe wall of the oxygen-steam inlet pipeline. The reforming furnace with the central burner nozzle solves the technical problem that an existing reforming furnace with the metal burner nozzle is easily damaged by combustion, avoids partial combustion caused by uneven mixing of fuel and an oxidizing agent in an original reforming furnace, overcomes the defects that a high temperature region of the original reforming furnace is located around the furnace wall and then prolongs the service life. Under the normal operation, the service life of the reforming furnace with the central burner nozzle is 24-36 months, thereby greatly saving production and operation costs of enterprises.
Description
Technical field
The present invention relates to a kind of metal burner reburner.
Background technology
Existing metal burner has the flow field, uniform temperature fields is reasonable, the advantage of long service life etc.Yet the operation of the efficient stable of burner needs continual the flowing of cooling water to take away 800～1400 ℃ of heat exchange amounts to burner in reburner, guarantees the normal operation of burner.But existing metal burner nozzle cooling water system can not be transported to cooling water in the metal burner when emergency episode occurring and cause power failure, and causes metal burner scaling loss.So, how to design the cooling water system that satisfies the cooling use of metal burner, safe and efficient stable operation in the future plays an important role for the metal burner.
Summary of the invention
In order to solve existing metal burner reburner burner easily by the technical problem of scaling loss, the invention provides a kind of reforming furnace with central burner.
Technical solution of the present invention:
A kind of central metal burner reburner, comprising central burner nozzle, burner part, combustion parts, catalytic conversion part and converter exit portion, described central metal burner comprises oxygen+steam inlet pipeline a, is arranged on oxygen+cooling water inlet passage b and coolant outlet passage c on the pipeline a tube wall of steam inlet; Its special character in: also comprise cooling water system, described cooling water system comprises the circulating water emergent water system of unifying, and described circulation comprises atmospheric water tank, pump group, import orifice plate, burner inlet channel, burner outlet conduit, the outlet orifice plate that connects successively and consist of water loop; Described emergent water system comprises high pressure nitrogen storage tank, nitrogen buffer tank, high-pressure water tank, high-pressure water inlet magnetic valve, High Pressure Drain magnetic valve; Described nitrogen buffer tank communicates with high-pressure water tank, and described high-pressure water tank communicates with the burner inlet channel after by the high-pressure water inlet magnetic valve, and described burner outlet conduit and High Pressure Drain magnetic valve join, the outlet ground connection ditch of described High Pressure Drain magnetic valve; The flowmeter of described outlet orifice plate and high-pressure water inlet electromagnetic valve linking.
The present invention has advantages of:
Central metal burner ejection of the present invention is effectively organized the oven gas in reburner (natural gas)+steam flow field up to oxygen+steam of 100-400m/s, has avoided former reburner fuel and oxidant to mix uneven and inclined to one side burning that cause; The former reburner high-temperature region drawback around in the furnace wall has been avoided in the high-temperature region of central metal burner of the present invention on center line in stove, and then improved reburner service life, under normal operating, the central metal burner reburner life-span is 24-36 month, has greatly saved the costs of production and operation of enterprise.
2, the present invention adopts the high-pressure water tank of nitrogen driving to provide emergency cooling water to burner, when gasification furnace cuts off the power supply for some reason, atmospheric water tank stop supplies cooling water, because high-pressure water inlet magnetic valve and High Pressure Drain magnetic valve are normally closed solenoid valve, all open this moment, and the water in high-pressure water tank under high pressure nitrogen drives, enters trench after high-pressure water inlet magnetic valve, import orifice plate, burner, outlet orifice plate and High Pressure Drain magnetic valve, guarantee the emergent cooling of burner, prevented the improper scaling loss of burner.
