Waste heat boiler manufacturer Hebei Supply

Waste heat boiler by fuel oil into waste heat boiler, gas waste heat boilers, coal-fired heat recovery boilers and waste heat boilers and other foreign media. Divided by use of waste heat hot water boilers, heat recovery steam generators, waste heat boilers and other organic heat carrier. Organic heat carrier boiler brief: The creation of the drum has for pickling, thermal measurement, water level gauge, water supply, dosing, continuous blowdown, emergency drainage, safety valve, air valves and other socket, and manhole devices . Drum has two spring safety valve; Water level two, two-color water level gauge quartz tube, safe, reliable, easy to observe, correct instructions. In the drum inlet hole and other holes may use a larger temperature difference between the casing pipe seat near the holes to prevent cracks due to thermal fatigue. Drum inside the apparatus is provided with a separator for separating apparatus, as well as boiler feed water, dosing and other connecting pipe. Drum is equipped with two bearings, a fixed bearing, an active support. Organic heat carrier boiler corrosion phenomena: the common waste heat boiler smoke tube heat exchanger, generally in a multiple relationship between its metal heating surface minimum wall temperature and the temperature of the hot fluid discharge. About smoke tube heat exchanger, when the metal is heated wall surface temperature if the request is not less than 150 ℃, its exhaust gas temperature is usually not less than 300 ℃, this would certainly cause cryogenic condensation corrosion. Taking into account low temperature equipment operating conditions, the safety factor of 1.5 times to count, waste heat boiler flue gas temperature is not lower than 450 ℃, the waste heat boiler at this time about 0.5 tons of recyclable heat recovery efficiency is still low. In addition, when the temperature is just checking the temperature, when the operating conditions necessary to stop because the operation needs adjustment, there is no way to stop the adjustment directly to the wall temperature control. When the waste heat boiler heating surface of the rear metal wall temperature is below the condensation point sulfuric acid vapor, liquid sulfuric acid will constitute its appearance. For a long time, the rear surface of each heat exchanger equipment due to condensation and corrosion caused by recurrent episodes. So that the waste heat boiler design had been progress in the exhaust gas temperature or the use of non-metallic materials poor to alleviate condensation heat transfer and corrosion phenomenon, but still did not deal with the problem fundamentally. Nonetheless, waste heat recovery equipment often operate as usual after a year or two will show corrode until perforated. Routine Maintenance organic carrier boiler heat: 1, the water level was observed with a water table level, timely repair corrupted tables 2, gauge damage, dial unclear timely replacement of 3, run, run, drip, drain valves can repair the timely repair or replacement ; 4, insulation, strengthen the lining layer intact. 5, class flexibility and working conditions should be checked regularly gearing, to timely lubrication to ensure their normal work; 6, check and repair the fan, water supply pipeline valves, feed pumps and the like; 7, check all connections boiler system piping method Portland and other parts must not be tight leakage; 8, if the occurrence of severe vibration induced draft fan, you should stop for inspection, the general system of internal impeller wear caused, should exchange; 9, the boiler set box at the bottom of the ground water and heating pipes not to prevent moisture corrosion base; 10, regular inspection of the three-way valve flapper valve shaft seal, shaft and electric equipment operation and timely troubleshooting; 11, always check the boiler steam pressure, water level, and the superheated steam output temperature is normal; 12 Check all the basic bolt loose. Must ensure a secure, otherwise it will cause vibration; 13: the class must be flushed once the water level gauge; 14, put the steam valve manually or turn on the water at least once a week experiment, automatic release steam or drain test at least once every three months; 15, Rinse gauge normal operation once a week, check the trap every six months at least once; and draw red lines indicate the operating pressure on the dial, after verification seals; 16, low water level alarm, low water level interlocks, overpressure, over-temperature alarm, over-pressure interlock device, at least a month as an alarm interlock test; 17, equipment maintenance and safety checks of accessory test to make detailed records, boiler operation and management staff should regularly checks .
