Make the same score the structure of blaze burner and principle detailed solution
Smooth blaze burner is in order to enter to burner gas the air that wants with combustion place, coming back stream implement below action, gas with the whirl with intense air, the edge is perpendicular spread out at the boiler setting surface of line of burner brick center, tightening the burn oneself out inside a space that relies on boiler setting, form garden dish model blaze, its diameter is in 1 ～ 3m, its ply is in 100 ～ 200mm. After using smooth blaze burner, because heat radiation ability is strengthened, temperature field is even, reason warms up rate is rapid, metallic oxidation burns caustic rate is low, heat equably to realizing rolled steel, heat quickly, managing fuel has distinct effect
The gas burner that make the same score blaze
One, structural principle this model burner with Jiao Lu gas for fuel, those who enter burner is gas with air with rotating strongly the edge is perpendicular spread out at the boiler setting surface of burner center line, mix combustion to form smooth blaze inside a space that relies on boiler setting surface closely, blaze diameter 1 ～ 3 meters, blaze ply 200 millimeter of 100 ～ . After using smooth blaze burner, because radiant energy force is powerful, temperature field is even, can realize rolled steel to heat equably, heat quickly, managing fuel is remarkable.
Burner structure signal, see a picture 1. Performance data, see a table 1; Structural dimension, see a table 2.
2, burner performance data and specifications Energy of burner model burner (when mark rice 3/ ) gas low hair quantity of heat (1000 anxious / mark rice 3) force of atmospheric pressure of the coal before burner (Pa) pressure of the air before burner (Pa) PM- Ⅲ - ～ of 1 30 13400
3, service instruction
1. The Jiao Lu that this burner uses or city are gas, its send limits of quantity of heat to be 3200 ～ 4200 kilocalorie / mark rice 3, shi Kegen of choice burner model presses this burner function to express energy of medium burner of conversion of quantity of heat of rated and gas hair according to the gas and calorific amount that uses actually, choose burner model according to this.
2. When warm-up air, burner energy falls for following numerical value (gas pressure is constant before the mouth) : Air warm-up temperature (℃ ) the percentage that energy of 150 200 250 300 350 400 is normal volume (％ ) 80 76 72 70 65 64
3. When 700Pa of force of atmospheric pressure of the coal before burner, burner also can burn normally;
4. The direction of rotation of burner blaze is left, right change direction differently. When be used side by side inside same furnace kiln, should change the blaze of two burner of photograph adjacent to tone to be it is beautiful instead;
5. After burner uses period of time, should clear the spray orifice of gas shower nozzle.
4, install a requirement
1. Burner can be installed go up in side wall or roof. Installation is on roof when, over all dimension is a graph 1 in be shown. Should install burner brick is shown in graph of the take out when side wall two skew angle;
2. The plane inside burner brick and boiler setting (very) inside plane maintains evenness, do not allow boiler setting (very) planar and bulgy, the influence burns normally;
3. After locating burner first, take-over again, conduit installation should not affect the fixed position of burner.
5, ignition
1. Open furnace door and flue flashboard, open air-blower, blow sweep gas can be burned inside clean the chamber of a stove or furnace;
2. Ignition. The air before small open burner butterfly a powerful person, offer a few air, bright fire is put in ministry of root of mouth of burner brick horn, reopen is gas a powerful person. After catching fire, adjust empty gas scale, achieve groove. Should notice quantitative change of pressure current of gas, airy is changed at any time later, adjust in time, maintain combustion stability;
3. Be like unignited, answer to close gas valve instantly, open air valve, blow afresh after sweep and proving a cause, ignite again;
4. Gas valve is closed first when stopping furnace.
