industrial automatic gas central heating steam boiler
Operation of the boiler, including what? Including the operation of the boiler, what does? Following on from the Henan fast boiler company to tell you about: 1. The water level regulation of normal water level in the middle of the gauge (1) of the boiler. Operation with the magnitude of the load is adjusted: to maintain a high level during low load, high load to maintain a low level. Changes should not be down more than 40 mm. (2) to be run on the water level gauge to compare the two groups, if the water level display should be corrected promptly identify the cause. (3) To achieve a balanced continuous boiler feed water, ground water supply, water supply less, to maintain the water level in the normal water level fluctuates slightly in the vicinity. (4) load change is large, prone to false level. Pay attention to judgment, in order to avoid misuse. 2. Steam pressure regulator (1) when the boiler must constantly monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. (2) increasing the boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. (3) boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and to adjust the amount of water. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes. 3. Combustion adjustment (1) combustion index. Normal combustion boiler comprises a uniform supply of the fuel, reasonable ventilation, adjusting three basic aspects combustion. B. maintain a high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100-1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. C. fuel ash to reduce ash content in the combustibles to be below 10%. d. reducing the temperature of the exhaust gas boiler exhaust gas temperature should be controlled below 200 ℃. e. excess air negative pressure holding furnace boiler 1.2-1.4, by adjusting the balance of the blowers to maintain the furnace pressure is 2-3mm. F. to improve the thermal efficiency of the boiler thermal efficiency of the boiler should be kept above 60%. (2) adjusting the combustion a. Reasonable amount and the distribution of fuel to the amount of air needed for combustion. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. b wind principle feature: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. c is the normal combustion conditions: fuel ignition start at 300mm from the shutter of coal, even flames, the fire bed formation, at the end away from the combustion grate at the end of 300-500mm. d. Hold appropriate furnace temperature to avoid coking. E. fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. F. less than 30 minutes residence time of the fuel on the grate. Our company provides services related to the installation of the boiler!
Beiqi Panther car 6 tons of steam condensing one fuel gas industrial automatic central heating steam boiler project has been successfully completed. This series boiler adopt advanced design concepts, using the waste heat of flue gas cascade, with the use of the condenser and the economizer fully absorb the waste heat in the flue gas, the boiler efficiency has been greatly improved.
Maintenance of the boiler plant food during the maintenance shutdown has deactivated which is to prevent boiler corrosion. Since boiler shutdown, a large boiler humidity, poor ventilation, if long-term in a wet state, oxygen in the air with the metal heating surface of the wet complete contact, the inner surface layer of brown rust generated; in addition, often the heat receiving surface of the gas side accumulating ash particles during operation, after the shutdown in the humid environment, will cause corrosion of metals. In the boiler shutdown process, the main reason is the presence of moisture and corrosion of metal surfaces of the air. Thus, as long as the metal surface or a metal surface with dry air (oxygen) isolation, can effectively prevent corrosion. The length of the parking time, there are packing, Paul dry, wet security, ventilation PROTECTION. 1, pressure maintenance Pressure maintenance is suitable for up to one week shutdown of the boiler. The residue pot pressure 0.05 ~ 0.1MPa, temperature slightly above 100 ℃. Boiler pressure and temperature to maintain regular methods using steam heating the water adjacent to the boiler, a heating boiler or intermittently. 2. Dry Dry care maintenance is a method to protect the desiccant into the pot and in the furnace. Its purpose is to keep no water jug. The utility model is suitable for long-term or seasonal shutdown boiler heating boiler. Open manholes and hand holes, the header and the drum-dried. When wet boiler room, with appropriate use of the furnace heat or light burning wood, so that the furnace, the furnace wall flue drying. After drying the boiler is cooled, the opening and tray formulated desiccant tube is placed in the pot, and a collecting box grate, then tightly closes the inlet aperture, and a valve connected to the hand hole to prevent air from entering. For some Mifengbuyan valves, plug board should be increased.
The advantages of gas industrial automatic central heating steam boiler Gas steam boilers advantage: designers will arrange commandment information again, simple and convenient operation of the facility. Gas-fired steam boiler is not only easy to operate, and as soon as possible to ensure the safety factor used. Energy-saving advantages: high-temperature gas steam boiler with characteristic base pressure, greatly reducing the use of water pressure level heating facilities, to immediately benefit from lower capital injection facilities. Also said that the proportion of raw materials and gas touched. Only proper and adequate oil ignited gas can produce ratios exceeding ignite rate, together with its ability to reduce vapor emissions and maintain two-way power-saving, very convenient. Gas steam boiler can be arranged according to the specific needs of the amount of vapor, reduce renewable resource conservation. The higher the specific requirements and the intermediate supply pairing methodology, the higher the power saving effect. The heat exchanger can continue to use sewage water calories, and thus can increase oxygen supply and drainage of water temperature. In accordance with the provisions of the Environmental Protection useless now need, doing everything, gas-fired industrial equipment is more commonly used. In severe conditions, serious vapor watering, the water content of the salt to enhance the micro gas steam boiler, water hammer audible in steam lines, steam splashing outwardly coupling joint living; or furnace tube if economizer line split, water vapor allowance is given below, when less water is generated, in turn, the situation will occur; less water when severe, it is possible to see the red water wall of furnace tubes can also smell burnt taste. Together, furnace tube will split, could hear explosions. Steam and smoke exclude the furnace mouth and fire security door from. Low water interlock device, if the amount of water is less than the target value, air-conditioning fan, booster fan and grate machine motor reducer operation should be terminated; Security Council water is less than the low water mark, water glass (plate) is black; cleaning sheet is not water clear micro gas steam boiler is not filled or slightly severe filled with water? Ways: first turn off the water level gauge, tap water pipe is connected, and then open the drain cock. If you can see the water line from the top lower, then it is filled with a little water, open the drain valve and place no problem of water. If severe filled with water, please use the emergency shutdown countermeasures.
