Factory Automatic Water Tube Gas Fired WNS 1 MW Normal pressure hot water boiler
Horizontal steam boiler accident treatment method: 1 overpressure accident boiler, boiler overpressure phenomenon of (1) a sharp rise in steam pressure, the pressure exceeds the allowable working pressure gauge pointer over the "red line" safety valve operating pressure is still elevated. (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. 1, the phenomenon of the boiler water (1) below the minimum safe water level line, or no visible water, the water table 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.
Fangkuai boiler for you to sort out 30 boiler operation common problems and solutions, after learning, do not forget to share with your friends oh. (6) what are the main factors affecting the wear rate? 1 flue gas, 2 flow rate of the material, 2 particle size of the material in the flue gas, and 3 the surface shape of the worn component. The velocity of air flow is the most important factor affecting the relative direction of motion of the worn material and the wear is proportional to the third power of the velocity. 7. Why should the bed temperature be controlled between 850 and 950? 1 the ash will not melt at this temperature, thus reducing the risk of slagging 2. Higher desulfurization efficiency 3 less nitride gas in combustion gas at this temperature 4 Alkali metal in coal does not sublimate at this temperature, which can reduce slagging on the heating surface. 8, why do you have to blow the boiler pipe? Some equipment in boiler steam-water system, such as dewarming water, start-up bypass, superheater, reheater pipeline system, are not suitable for chemical cleaning due to structure, material, arrangement and other reasons. So it is necessary to use the physical method to remove the residual debris before the new boiler is put into operation, so the steam produced by this furnace is used to blow the steam-water system and equipment. 9, what are the common methods of boiler maintenance? (1) Wet protection: there are diammonium method, ammonia method, maintain feed water pressure method, steam heating method, alkali liquefaction method, trisodium phosphate and nitrous acid mixed solution protection method; (2) dry protection: there are drying method (with pressure discharge) and desiccant method. 10, which causes the deterioration of steam quality (steam pollution)? (1) steam with water. The boiler's feedwater contains impurities. The feed water is heated into steam after entering the boiler, and most impurities are transferred into the boiler water. So many cycles, the impurity concentration in the boiler water becomes higher and higher. Furnace water containing high concentrations of impurities is carried by saturated steam, which is called steam carrying water, which is called mechanical carrying. The first reason for steam pollution. (2) Steam-soluble salt. At higher working pressure, steam can dissolve some salts, which is called selective transport, which is the second reason of steam pollution.
Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new boiler equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).
Henan gas boiler shutdown operation process: 1, electric control box Press Henan gas boiler "shutdown" button; 2, burner servomotor return to the initial position, the throttle valve is fully closed and gas; 3, solenoid valve and gas regulating safety valve is closed, the blower stops rotating; 4, after determining the water temperature is below 50 ℃, stop the circulating pump. 5, closing the manual gas valve; 6, close the water supply valve and return valve; 7, check the gas lines, water lines, air leak valve for leaks; 8, down air switch; 9, when the long-term without cutting Henan power gas-fired boiler.
