Technical specification for safety furnace (fixed hearth chamber furnace)

1, safe, all furnace must have the following components and safety facilities. The outlet temperature of the automatic adjusting means; the feedstock oil automatic control means; furnace, convection, furnace tubes, radiation, temperature indication of the flue;
Population and superheated steam pressure gauge furnace; damper and flue baffle; emergency venting devices; blast doors; hearth and back elbow tank fire steam line.
3. The new furnace according to prescribed procedures must be put into use, the heating curve Ovens.
4. Furnace ignition off good hole, the flue baffle opening to 1/3 1/2, fuel oil systems circulation and circulation of raw materials, ready to soak diesel ignition stick.
5. Ignition steam furnace residue gas rush the net, on the upper end of the burner will ignite ignition rods, others to leave the bottom of the furnace, steam slightly open, and then open the oil line. Point fuel fire, regulate oil and gas than to a normal state.
6. Cited gas off the net water storage and condensed oil and drained in a safe place for more than 15 minutes, the laboratory analysis of the oxygen content of less than 1%, before the vote with the ignition. Gas into the blast furnace must pass the flame arrester.
7. Ignition fireman can not face the fire mouth and see the fire window to avoid tempering wounding. If the flame goes out, the fuel valve should be closed immediately, the furnace domestic demand steam purge in order to re-ignition.
8. Normal operation should always check the stove burning at any time to adjust, pay attention to check whether the tube bending, bubbling, peeling, redness and dark abnormal situation, pay attention to check back elbow, plug, entrances valve flange seamless oil phenomenon, abnormal, and immediately reported to the leadership, to take measures to deal with.
Case of burn-through caused by a ruptured tube furnace of fire or an emergency need into the furnace, the application of steam to put out the fire cooling treatment, no water is injected into the furnace for fire fighting and cooling.
10 into the furnace overhaul should handle into the equipment and operating procedures. Explosion-proof doors shall not be blocked with other objects, so as not to lose the explosion-proof effect.
11. Safety furnace heating or shutdown cooling must be strictly in accordance with the provisions of the heating and cooling rate.
12 emergency shutdown, against only wind instrument used to close the control valve, be sure to close the blast furnace hand valve.
(13) In case of the heating medium interrupts should immediately fire the furnace pass into the steam.

Industrial oven works

Digital instrumentation through a connection with the temperature sensor to control the temperature, the use of hot air circulating ventilation, air circulation system is divided into horizontal and vertical. Were confirmed by accurate calculation, the wind source is driven by the wind turbine blower motor operation via electric heaters, hot air duct into the oven to the studio, and will use the air intake duct after a re-circulating heated air source use, so can improve the temperature uniformity. Be used as door switch, air circulation system can quickly restore operating state temperature value. Oven structure and working principle:
1, the structure of industrial ovens
Industrial ovens for the inner and outer layer structure, the shell of the angle iron steel sheet, inside and outside the double-shell filled with fibrous material between. Industrial ovens used mostly aluminum silicate fiber material, it can play the role of insulation, forming a reliable insulation. Industrial ovens equipped with hot air circulation system and temperature measurement and control systems.
2, the principle of industrial ovens
Industrial ovens muffle furnace at work, the operator through the meter and temperature sensor to get inside industrial oven temperature value by the control system to operate. Industrial hot air circulation oven heating, cooling and heating mode compared to normal, with better gas flow, can speed up the industrial oven drying rate of the material.
Industrial ovens hot air circulation system consists of blower motor, wind turbine and electric heater components, air motor driven wheel sends cold wind, cold wind carries heat through electric equipment after heating duct into the industrial oven oven studio.
Industrial oven of hot air circulation system can improve the uniformity of the air temperature in the industrial oven door switch during the transportation of materials, the temperature value may be affected by a change in the uniformity of the air circulation system is conducive to the maximum recovery fast degrees operating state temperature.
 

Furnace (car bottom furnace) Introduction and safety technical regulations

Car Bottom Furnace Products:
For weight of more than ten tons to hundreds of tons of ingot heating before forging, furnace room or tunnel-type. Heated objects placed in the trolley, furnace loading and unloading by the workshop crane or other traction devices trolley pulled into or out of the furnace, the large ingot heating requirements furnace temperature evenly distributed, car bottom furnace is often a distributed heating burner and smoke crossing dispersion and dispersion of smoke (arranged on the side wall of the furnace).
Technical specification for safety:
1, safe, all furnace must have the following components and safety facilities. The outlet temperature of the automatic adjusting means; the feedstock oil automatic control means; furnace, convection, furnace tubes, radiation, temperature indication of the flue;
Population and superheated steam pressure gauge furnace; damper and flue baffle; emergency venting devices; blast doors; hearth and back elbow tank fire steam line.
3. The new furnace according to prescribed procedures must be put into use, the heating curve Ovens.
4. Furnace ignition off good hole, the flue baffle opening to 1/3 1/2, fuel oil systems circulation and circulation of raw materials, ready to soak diesel ignition stick.
5. Ignition steam furnace residue gas rush the net, on the upper end of the burner will ignite ignition rods, others to leave the bottom of the furnace, steam slightly open, and then open the oil line. Point fuel fire, regulate oil and gas than to a normal state.
6. Cited gas off the net water storage and condensed oil and drained in a safe place for more than 15 minutes, the laboratory analysis of the oxygen content of less than 1%, before the vote with the ignition. Gas into the blast furnace must pass the flame arrester.
7. Ignition fireman can not face the fire mouth and see the fire window to avoid tempering wounding. If the flame goes out, the fuel valve should be closed immediately, the furnace domestic demand steam purge in order to re-ignition.
