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!
Horizontal fired hot water boiler suppliers a few precautions, overpressure accident 1 boiler, steam boiler overpressure phenomenon of (1) a sharp rise in steam pressure, the pressure exceeds the allowable working pressure gauge pointer over the "red line" is still working pressure safety valve l high. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Second, an accident boiler water, boiler water shortage (1) below the minimum safe water level line, or can not see the water level, the water level gauge glass (plate) as a white. (2) as a full-color water level gauge vapor instruction color. Low water level alarm signal (3) water level alarm occurs. (4) low water interlocking means, the water level should be below a prescribed value blower, Fan, grate reduction motor stops running. (5) a sharp rise in the superheater steam temperature, higher than the outlet steam temperature. (6) boiler exhaust gas temperature rises. (7) the water flow is less than the steam flow, causing Should the water tube due to tube cracking or economizer, an opposite phenomenon occurs. (8) When a serious water shortage, can smell the burnt smell. (9) When a serious shortage, the door can be seen from the red-hot waterwall tubes. (10) a serious water shortage, the furnace tube may rupture, then can hear the explosions, smoke and steam from the door, watching spray the fire door. 2, boiler water treatment (1) through the "waters", sentenced to severe water shortages, emergency shutdown must be prohibited blind to the boiler feed water. (2) through the "waters" sentenced to a slight lack of water, it should reduce fuel blast, the wind, and slowly feed water. Third, full water boiler 1 accident phenomenon (1) above the maximum allowable water level line, or can not see the water level, the water level gauge glass (plate) dark color boiler filled with water. (2) all of the water phase as a color level gauge indication color. High-water alarm signal (3) water level alarm occurs. (4) decreased superheated steam temperature. (5) water flow is not normally greater than the steam flow. (6) water in a large number of sub-cylinder, severe trap operation. (7) with a large amount of water steam severe, increased salinity, water hammer occurs in the sound of the steam pipe, the steam connection flange outwardly dripping take place. 2, steam boiler full of water treatment rinse water table, determined to be minor or serious full of water full of water. Method: Close water table, the water pipe connected cock, then open drain cocks As can be seen from the decreased water level, indicating a slight full of water, the water supply is stopped, the drain valve open, put to the normal water level. Such as severe filled with water due to take emergency shutdown measures.
6 tons gas steam boiler steam pressure adjusting a boiler operation, must frequently monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. Second, increasing 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. Third, the 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 the amount of feed water 8 to adjust. 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.
