At present, the hot high-grade electric atmospheric pressure boiler is a kind of thermal energy equipment with high temperature and high pressure. It is widely used in various industries, such as electric power, machinery, chemical industry and civil heating, which require the boiler to supply a large amount of heat energy. However, users are careful to pay attention to some items in order to ensure the normal operation of the equipment. So, let me give you the following interpretation of the operation of the atmospheric pressure boiler points for attention? The details are as follows:
1, attention should be paid to adjusting the water supply mode of the equipment at present, because the boiler and the system are separated from the system when the operation of the electric atmospheric hot water boiler is stopped, the users should pay attention to the operation of the electric atmospheric pressure boiler and the heating system respectively. In addition, the user should first put the boiler water to the lowest water level of the boiler expansion tank and then carry on the system water. At the same time, the gas in the equipment should be discharged when the system is filled with water. 2. pay attention to the test equipment ignition device before the ignition of the normal pressure boiler, the user in addition to the boiler auxiliary equipment inspection, but also should pay special attention to the automatic opening and closing valve opened is sensitive and reliable, but also should pay special attention to the automatic opening and closing valve opening is sensitive and reliable And pay attention to observe the boiler water level change, if the equipment stop running, its water level rises rapidly, it indicates that the automatic opening and closing valve leakage of the equipment is serious, the user should carry on the maintenance in time or replace the parts of the electric normal pressure boiler.
2, pay attention to the temperature change when the equipment is running, if the water temperature is too high, it is easy to cause the vaporization at the inlet of the circulating pump, so as to affect the normal operation of the equipment pump. Therefore, when using the equipment, users should pay attention to controlling the effluent temperature of the electric atmospheric pressure boiler, and the effluent temperature of the equipment should be controlled below 90 ℃. In addition, if the user needs a longer period of time to stop the operation of the more discounted electric atmospheric pressure boiler, the user shall close the valve of the boiler inlet and outlet. So that the circulating water in the equipment system is prevented from pouring into the boiler and the system height emptying phenomenon is formed so as to affect the re-start of the electric atmospheric pressure boiler.
Energy-saving measures and methods of industrial boilers which industrial boiler energy-saving measures and methods which 1, to increase the capacity and improve the thermal efficiency of boilers and inefficient small compared to the large-capacity high-efficiency industrial boilers, can greatly improve the utilization of energy rate, so as to obtain greater economic benefits. Meanwhile, the cogeneration project enables conversion of exhaust or extraction steam turbine for heating, not only can reduce the loss of turbine exhaust steam, but also help to save coal resources. Industrial boiler thermal efficiency of China's low is a fact that can not be ignored, usually operating efficiency even lower. Therefore, improving the efficiency of industrial furnace hot pot, is crucial for energy savings. In one aspect, by improving the quality of the insulating material, thicker insulation, heat loss can be reduced. On the other hand, the use of secondary air system, can facilitate a more complete combustion of fuel, the effect is very significant. 2, the heating surface to reduce coking and fouling of industrial boiler during running, prone to coking, fouling phenomenon, resulting in increased and then decreased local resistance to the flow cross section. Not only conducive to smoke, but also so that heat transfer is reduced, further increasing the temperature of the flue gas. Industrial boilers and cleaning agent has a good cleaning effect, can be put in the appropriate amount sublimation decompose at high temperatures, with the heating surface of the coke, slag and contacts a chemical reaction can be automatically off after decomposition. Meanwhile, a method of periodically purging is also more effective in the early formation of fouling was loose state can be cleared periodically sootblowing. If the attachment is too long time, will translate into close like fouling, thus increasing the difficulty of cleaning up. 3, to ensure the quality of coal and industrial coal-fired boilers with coal is crucial, its moisture, volatile content factor for the speed of fire, as well as affecting the combustion temperature is extremely obvious. Maintain proper moisture content can be reduced with reduced leakage occurrence of coal and fly ash, coal seam and helps enhance the evacuation ventilation. If the moisture content is too high, will affect the speed and the temperature in the furnace, heat loss will be increased exhaust smoke. Industrial water boiler heating surface for scaling impact of large scale for each additional 1mm, the overall thermal efficiency of the boiler will be reduced by 3%. 4, many factors affect the lower exhaust gas temperature industrial boiler flue gas temperature, within the course of the economizer scale, cleaning up soot neglect of smoke in the furnace wall channeling smoke, poor treatment effect, can cause elevated exhaust temperature. On the one hand, to deal with the heating surface appears slagging, fouling and scale phenomena take timely measures to eliminate, minimize or avoid their presence. On the other hand, on the rear of the boiler heating surface is improved or increased. Industrial boiler flue gas temperature, objectively reflects the utilization of exhaust heat. But not as low as possible, the exhaust gas temperature is too low but not conducive to the normal operation of the boiler.
Hot water boiler is the essential equipment of our hotel, one of the parties to provide fast condensing pressure atmospheric hot water boiler immediate operational effect. Our demand for environmentally friendly and out of the hotel itself, very high environmental performance requirements for boilers, party fast products fully meet our needs, the index after testing are in line with the relevant provisions of the State; with the outside atmospheric pressure remains stable sufficiently improved security index boiler, eliminating our worries. --customer feedback
The reason you must know the problems of energy consumption boiler (boiler exhaust gas temperature) produce exhaust gas temperature of the boiler problem (1) shift the center position on the furnace flame, the exhaust gas temperature rises a multi-burner into the upper interlayer with the wind unreasonable . b upper stoker coal excessive. c burner tilt position shifted, resulting in the shift of the center position of the flame. d burner auxiliary throttle opening degree command deviations, lack of oxygen, pulverized coal combustion delayed. e a high-pressure fan outlet, wind speed is too large, the pulverized coal combustion furnace into the shift position. f leakage boiler, the furnace excess air factor export. g coal is too thick, ignition and slow combustion reaction. h low volatile coal, high ash, high moisture, ignition difficulties, to delay the combustion. i mill outlet temperature is low, the air entering the furnace temperature was lowered powder mixture, combustion delay. (2) When the boiler "four leak" for plugging, resulting in a superheater, reheater or economizer to reduce heat transfer area. (3) the supply air temperature is high. (4) high flue gas dew point temperature. (5) soot blowing equipment investment is not normal. (6) heating surface coking, fouling. (7) The air preheater ash fouling, heat transfer efficiency is lowered. (8) strict quality control, internal heating surface junction. (9) low water temperature.Free Chat
