Abstract
An oven combustion device of a top-blown converter is composed of a combustor, an automatic regulating valve set and a leakage alarm. The combustor is composed of a fuel pipe and an oxygen pipe sleeved in a coaxial mode. The fuel pipe and the oxygen pipe of the combustor are respectively connected with a natural gas outlet pipe and an oxygen outlet pipe of the automatic regulating valve set in threaded mode through flexible metal tubes. The leakage alarm is arranged above a flange at an outlet and inlet of an oxygen regulating valve of the automatic regulating valve set and below a flange at an outlet and inlet of a natural gas regulating valve of the automatic regulating valve set. The oven combustion device of the top-blown converter is complete in combustion, high in spraying speed of a flame outlet, strong in flame rigidity, stable in combustion and free of backfire. In addition, the oven combustion device of the top-blown converter is capable of automatically regulating oxygen/oil ratio and guaranteeing combustion effect. By means of the leakage alarm, the oven combustion device of the top-blown converter is safe and reliable, and suitable for baking, warming and warm-keeping of the top-blown converter.
Description
One, technical field
The utility model relates to a kind of pyrometallurgy equipment, specifically is a kind of top-blown converter baker burner.
Two, background technology
The top-blown converter structure is unique, and fuel, flue gas are come in and gone out and accomplished by furnace roof one circular port, and flue gas is short at residing time in furnace; Therefore speed, the efficient to fuel combustion all has higher requirements, and traditional burner requires that the sufficient flowing space is arranged, the heat transmission speed is slow, and because the flue gas refluence; Cause atomization badness easily; Combustion instability, poor stability can't be competent at top-blown converter baker, intensification, insulation needs.
Three, utility model content
The purpose of the utility model provides a kind of top-blown converter baker burner; The burning of this device fully, the flame export jet velocity is high, flame rigidity is strong, not tempering of flameholding, can regulate the oxygen oil ratio automatically; Guarantee combustion efficiency, the warning of band leak detection, safe and reliable.
The utility model is realized above-mentioned purpose through following technical scheme: a kind of top-blown converter baker burner; Form by burner, automatic regulating valve group and leakage alarm; Said burner is connected with the automatic regulating valve group through metal hose, and leakage alarm is placed in below the flange top, oxygen regulating valve gateway and the natural gas adjusting valve gateway flange in the automatic regulating valve group in the automatic regulating valve group.
Said burner is by burner tip; The burner outer tube; Pipe in the burner, adpting flange, cartridge and oxygen hose constitute; The oxygen hose of said burner is connected with the oxygen outlet gas thread of automatic regulating valve group through first metal hose, and the cartridge of burner is connected with the gas outlet gas thread of automatic regulating valve group through second metal hose.
Pipe is coaxial package in said burner outer tube and the burner.
One group of probe of said leakage alarm is placed in 10cm place, natural gas adjusting valve gateway flange top in the automatic regulating valve group, and another group exploration head is placed in 10cm place, flange below, automatic regulating valve group oxygen regulating valve gateway.
The operation principle and the process of the said top-blown converter baker of the utility model burner are:
Natural gas, oxygen get into outer, the interior pipe of burner respectively via the control of automatic regulating valve group; Do not mix at burner head, oxygen is injected by interior tube hub, and natural gas gets into burner hearth through outer tube head restrictor ring; Under the injection of oxygen high velocity air, natural gas is fully burned.When natural throughput changed, amount of oxygen was followed the tracks of amount of natural gas and is changed, and guarantees combustion efficiency.The automatic regulating valve group is provided with natural gas, oxygen leak detection apparatus respectively, has guaranteed safety.
The outstanding effect of the utility model is:
1, adopts the pressure loss of this burner lower, can reduce energy consumption to greatest extent, practice thrift more operating cost than normal burner.Operating flexibility is very high, regulates than surpassing 6:1.
2, the combustion-supporting oxygen of this burner sprays at a high speed through nozzle through the burner central tube; And 12 annulus throttlings of the cartridge of natural gas via burner are to spray than low velocity; The natural gas jet forms strong shearing, stretching, stirring action each other under oxygen high speed injection; Spray into burner hearth after fully mixing and burn, flameholding, flame rigidity is strong.
3, owing to be furnished with the automatic regulating valve group, through DCS control, amount of natural gas changes, and amount of oxygen is made corresponding adjustment thereupon, guarantees atomizing effect, thereby keeps the rigidity of flame, and is not flame-out.
4, the burner arrangement of this burner need not to go deep in the stove at fire door 10cm place, and head adopts high-temperature alloy material to make, and smoke backflow is to outlet and suck the air hybrid cooling, has guaranteed that burner is almost harmless, long service life, and cost is controlled.
