Description

The two heat-accumulating burners of the embedded upper and lower combined type of a kind of burner block

Technical field

The invention belongs to the field of combustion technology on heating furnace and heat-treatment furnace.Be particularly related to the two heat-accumulating burners of the embedded upper and lower combined type of a kind of burner block.

Background technology

Traditional double heat-accumulating burner is in the time of design and installation, burner block end face is fixed on two heat-accumulating burner body front ends, concordant with furnace wall castable refractory, at burner block surrounding pouring fireproof material, because burner block is larger, 1 row anchored brick can only be set between burner block, consider that furnace wall castable refractory expands in the time of high temperature, need between burner block, need to arrange 1 6～10mm dilatation joint, due to the partition effect of dilatation joint, the anchored brick being fixed on furnace wall steel plate does not have the effect that sockets burner block by castable refractory, cause after stove operation a period of time, burner block is under thermal expansion stress and airflow scouring, tilted to stove, the production accident such as even cause that furnace wall caves in.The two heat-accumulating burners of the embedded upper and lower combined type of burner block that the present invention relates to adopt the sky of miniaturization, coal gas burner brick, weight is lighter, be convenient to install, it is mainly by air heat-accumulating burner, coal gas heat-accumulating burner and supporting burner block combine, upper heating burner gas port under, air port is upper, otherwise under add, burner block is embedded in furnace wall castable refractory simultaneously, sealing closely, easy for installation, being convenient to furnace wall stays and establishes dilatation joint, solve traditional double heat-accumulating burner because furnace wall castable dilatation joint is set, cause furnace wall anchored brick not have the effect that sockets burner block by castable refractory.

Summary of the invention

The object of the present invention is to provide the two heat-accumulating burners of the embedded upper and lower combined type of a kind of burner block, solve defect and deficiency that existing pair of heat-accumulating burner burner exists.

The present invention includes housing 20, air heat storage tank 16, coal gas heat storage tank 15, gas port burner block 1, air port burner block 18.Air heat storage tank 16 and coal gas heat storage tank 15 adopt upper and lower textural association in housing.End " recessed " groove that gas port burner block 1 and air port burner block 18 are arranged on respectively coal gas heat storage tank 15 and air heat storage tank 16 is assembled together, in the time that coal gas heat storage tank 15 and air heat storage tank 16 inwalls are built high-strength light castable 11, its end pours into " recessed " groove structure, concave surface than the inner chamber of coal gas heat storage tank 15, air heat storage tank 16 wide go out 25～30mm, the dark 75mm of groove, forms the assembling of " concavo-convex " face with gas port burner block 1, air port burner block 18; Gas port burner block 1 be upper and lower combined type with air port burner block 18, and when burner is arranged on upper furnace, air port burner block 18 is upper, gas port burner block 1 under, the upper and lower oblique mixing of empty, Gas Flow; When burner is arranged on lower furnace portion, gas port burner block 1 is upper, air port burner block 18 under, coal, the upper and lower oblique of air stream are mixed.

Gas port burner block 1, air port burner block 18 are designed to " boss " structure, while assembling with burner body, burner block inserts burner body 70mm, in the time that burner block is installed, be squeezed into 5mm at burner block surrounding parcel 10mm containing zirconium tapetum fibrosum thick, form feltwork sealing surface; Both sides and top at burner block respectively arrange 2 drag hooks 22, the boss of gas port burner block 1, air port burner block 18 is hooked in drag hook 22 one end, the other end is welded on the gusset 24 of burner shell 20, by the fixing gas port burner block 1 of drag hook 22, air port burner block 18, gas port burner block 1, air port burner block 18 are connected in aggregates with burner body, prevent that burner block from installing fixingly unstable, the furnace wall phenomenon of collapsing occurs; In burner shell both sides and centre position 13 and 13 anchored brick drag hooks 23 of 13 anchored bricks are set altogether, in the time building furnace wall castable refractory 14, socket castable refractory 14 by being arranged on anchored brick 13 on burner body, furnace wall refractory material 14 is built by laying bricks or stones more reliable, improves the service life of furnace wall and two heat-accumulating burners.

Burner body is made shell by steel plate, and the liner of housing adopts the thick ceramic fiber blanket of 40～50mm and the thick high-strength light castable of 80～100mm compound heat-insulation structure.Burner when mounted, housing inserts furnace wall 150mm, burner installing plate and furnace wall steel plate inside and outside surrounding adopt continuous welding mode to be connected, after burner body is installed and is fixed, insert 150mm part surrounding welding anchoring hook in furnace wall steel plate, the spacing of anchoring hook is 100～120mm, the integrated poured castable refractory of housing surrounding, to strengthen the sealing of burner body, burner block and furnace wall steel plate junction surrounding, prevent burner gas leakage or burn with anger.

Air heat storage tank and coal gas heat storage tank include the parts such as heat storage, floater guide block, hot junction cavity, flase floor, flase floor installation screw and cold junction cavity.Air heat storage tank and coal gas heat storage tank are independent of one another, between leave 100mm heat radiation gap, guarantee that upper lower box completely reliably separates.In air heat storage tank and coal gas heat storage tank, place cellular heat storage, heat storage temperature end arranges floater guide block, covers the radiation of high-temperature furnace gas to heat storage, improves the service life of heat storage, and separates heat storage and hot junction cavity by floater guide block; Heat storage low-temperature end arranges flase floor, improves heat storage and stacks stability, and flase floor is fixed on cold junction cavity by construction bolt.

Hot junction cavity is connected with burner block, and establishes air port and gas port at the end face of burner block.Air port and gas port are combination up and down, and when burner is arranged on upper furnace, air port is upper, gas port under, empty, the upper and lower oblique of Gas Flow is mixed.When burner is arranged on lower furnace portion, gas port is upper, air port under, coal, the upper and lower oblique of air stream are mixed.

Cold junction cavity comprises gas entry (exhanst gas outlet), air intake (exhanst gas outlet) and loading hatch.Cold junction cavity end arranges loading hatch, to floater guide block, heat storage, flase floor are dismantled in installing and safeguarding at ordinary times.Loading hatch is arranged on cold junction cavity by flange, bolt etc.

The present invention has following advantages:

1, adopt embedded burner block, nozzle structure lightness, burner block thickness drops to 160mm by traditional δ=400mm, burner block profile size reduction to 30%, burner block weight drops to 70Kg by 600Kg, is convenient to install, safeguard.

2, embedded burner block adopts boss structure, by drag hook, burner block is connected in aggregatesly with burner body, clogs 10mm simultaneously and contain zirconium tapetum fibrosum between burner block and body, makes burner block, burner body connection more reliable;

3, burner body both sides arrange anchored brick, while solving the installation of traditional double heat-accumulating burner, 1 row anchored brick can only be set between burner block, consider that furnace wall castable refractory expands in the time of high temperature, need between burner block, need to arrange 1 6～10mm dilatation joint, due to the partition effect of dilatation joint, the anchored brick being fixed on furnace wall steel plate does not have the effect that sockets burner block by castable refractory, cause after stove operation a period of time, burner block is under thermal expansion stress and airflow scouring, tilted to stove, the production accident such as even cause that furnace wall caves in.
