Electric steam boiler to be taken by each of the cathodic protection measures components of the electric steam boiler is made of different materials. In order to prevent galvanic corrosion, cathodic protection measures must be taken. Sewage treatment electric steam boilers. Bottom electric steam boiler blowdown can prevent flue gas condensation. Since the flue gas is flue gas condensation (diesel or natural gas) and the flue gas temperature in the aqueous too low, water generated. A portion of the moisture is discharged from the chimney, the chimney wall is absorbed, the rest is deposited on the bottom of the chimney. Water produced by the following factors influence: flue gas temperature (efficiency 91%, the flue gas must be at a temperature of 170 ℃) where the total surface area heat chimney, chimney and chimney material. Maintenance of the burner. Electric steam boiler and burner maintenance, repair after steam supply. Because the products of combustion will corrode the boiler, clean up carbon deposits, therefore, not allow the products of combustion in the boiler memory stay too long. We first opened when an electric steam boiler burner door, the rear housing panel removed, unscrew the screws electric steam boiler cleaning the rear opening. Clean fuel gas piping with a wire brush. With a soft brush to clean the combustion chamber. Electric steam boiler to remove residue in the boiler, the cleaning opening is screwed on the screw, closing the burner door seal check is complete. If electric steam boilers installed in areas where temperatures below 0 ℃ must take the following precautions: If electric steam boiler room outside, the room temperature drops below 15 ℃ or 18 ℃, the electric steam boiler running all day long. If no one in the room for a long time, the water should be emptied in electric steam boilers.
The advantages of gas 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.
What is the main danger steam boiler? The main danger emergency steam boiler 1, surveillance, hazard control boiler steam boiler regular inspection tours, and monitor pressure, water level, temperature and combustion conditions to control the boiler operating conditions. And to take timely measures to ensure safety. 2, the processing operation of the steam boiler in special circumstances: (1) water shortage phenomenon: When the boiler water, the water level below the water table level limits not visible, low water level alarm emits an alarm, bell lights, low interlocking means so that the water level blower, fan, etc. closure operation; boiler exhaust gas temperature rise, a serious lack of water, lake taste top coke production, the door can be seen from the red-hot waterwall tubes, tube deformation or even explosion pipe, can be heard blasting sound, smoke and steam discharged from the door to see the fire door. Treatment: When judged as a serious water shortage, should an emergency shutdown, non-serious water shortage boiler water to the boiler. Immediately stopping the supply of fuel, the wind stops blowing weakened, the front portion of the coal grate furnace Pa, the maximum switch the grate, combustion slag hopper falls quickly, with irrigated off, after extinguishing the fire, stop the wind, open ash door, the door to promote accelerated cooling. Note: Do not feed water to the boiler, shall take measures to prompt blood pressure, prevent the accident, to refrain from watering methods to the furnace fire put out the fire. (2) boiler overpressure phenomenon: a sharp rise in steam pressure, exceeds the allowable working pressure gauge pointer over the "red line", the safety valve, the pressure is still elevated, issued overpressure alarm, steam temperature and steam flow rises cut back. Processing: weakened rapidly burning, manually open the vent valve or safety valve, to increase the water supply, sewage increase (normal water level at this time to keep the boiler), thus reducing the temperature of the boiler water a boiler drum pressure decrease. (3) boiler tube phenomenon: the waterwall tubes blasting significant audible pops or jet sound, until the furnace by the combustion pressure becomes the negative pressure combustion, flue gas and steam and has viewed from the fire door, the door does not close, etc. discharge, although the water supply amount is increased, but difficult to maintain the normal water level and the pressure reduced, the amount of water to abnormally greater than the amount of steam, the exhaust gas temperature decreases, the chimney white smoke, the furnace temperature is reduced, or even extinguished, water flow out of the bottom of the boiler. Treatment: furnace tube rupture is not serious and can maintain the water level when the accident not to expand, may reduce short-term load operation, serious burst pipe and the water level can not be maintained, must be an emergency shutdown. But the wind should not stop, should continue to Sheung Shui, lower wall temperature. Such as: lack of water wall overheating, while burst pipes, emergency shutdown should be prohibited to the boiler feed water, the withdrawal of the furnace over the fire as soon as possible, reducing the furnace temperature, reducing the degree of superheating boiler. (4) steam boilers will produce full of water, such as priming scene of the accident, should take timely and effective measures to eliminate given. (5) boiler operation, in the event when one of the following circumstances, should immediately shutdown :( a) boiler water level below the lowest water level gauge visible edge; (b) increasing water supply and other measures, but the water level continued to decline; (iii ) boiler water level exceeds the highest visible level, the drainage can not see the water level; (iv) to pump all the water system failure or malfunction, not bottled water to the boiler; (e) all of the water table or valve failure; (vi) is set in a stripping all space gauge failure; (vii) damage the boiler element and endanger the safety of operating personnel.
