heavy oil fired steam boiler beer brewery in germany
The competition, the segment is slowly 45 contestants only a female welder, most of the other competitors from China Electric Power Construction, veteran welders in the petroleum, petrochemical, and other large number of country prefix units, with a very rich practical operation of work experience. Faced with numerous welding expert, slowly segment did not flinch and fear, but to actively exercise their welding ability, the old master who humbly ask to try a variety of different welding methods, and repeat the training to do practice makes perfect. By her welded boiler parts forming the United States, no weld defects neat; in her station, welding clean, neatly stacked tools, work order. It is because of her usual work down to earth, hard work and practice, lay a solid foundation for the success obtained.
In food factories, heat source equipment is essential. In the process of food processing, the process of disinfection and ripening of raw materials is inseparable from the application of boilers. The oil and gas boilers produced by ZG boiler can provide industrial steam or hot water for food processing to transfer heat.
What problems should be paid attention to in maintenance Electric normal pressure Boiler
Nowadays, advanced electric atmospheric pressure boilers need to be used in industrial production as well as in daily life. However, the electric atmospheric pressure boiler is a highly operational mechatronics equipment, such as customer inspection, maintenance is not timely will result in equipment line aging, equipment oil circuit and oil pump wear and so on. Therefore, users need to pay attention to the maintenance of equipment when running boilers, then, what problems should users pay attention to in the maintenance of electric pressure boilers with good performance?
1, pay attention to stop furnace detection electric atmospheric pressure boiler in the maintenance, users should let the equipment according to the normal shutdown procedure operation to achieve slow cooling, at the same time, Users should use pot water circulation and furnace ventilation to gradually reduce the temperature in the pot and furnace. It is worth noting that when opening the door hole of the equipment, users need to pay attention to preventing the burning of steam, hot water and flue gas in the boiler.
2, note that when users maintain the insulation, the combustor and flue of the detected atmospheric pressure boiler should be separated from the total flue or the other running boiler flue. The test results are as follows: (1) the combustor and flue of the tested atmospheric pressure boiler should be separated from the main flue or other running boiler. And the flue gate should be closed tightly, and in the partition after ventilation. In addition, the blind plate used in equipment partition should have sufficient strength and hardness to avoid being bulged by high pressure medium in the operation of electric normal pressure boiler, and the partition position should be clearly indicated to avoid confusion.
3, note that the user must completely cut off the connection pipe between the vessel and the gas equipment, especially to the combustible and toxic medium equipment before the inspection of the atmospheric pressure vessel is carried out by the user of the equipment container. In addition, the equipment container not only needs to close the equipment valve, but also needs to use the blind plate of the equipment to close the valve so as to prevent the gas leakage into the container and cause the fire explosion or poisoning accident of the valve so as to cause the combustible or toxic gas to leak into the container.
The scaling of gas-fired fired steam boiler beer brewery in germany not only reduces the thermal efficiency of the boiler, but also increases the temperature of the heating surface of the boiler, causes damage to the heating surface, and even causes the explosion accident of the boiler. Therefore, the use of soft water treatment equipment, strictly according to the process operation of boiler feed water softening treatment equipment, control boiler feed water quality, can delay the formation of the scale. At the same time, it is very important to control the boiler scale in real time, master the boiler scale and clean the scale if necessary. Because the temperature of the gas-steam boiler body and the steam-water heat pipe system is higher than the air temperature in the boiler room, some of the heat is emitted through radiation and convection into the surrounding air. This becomes a loss of heat. Boiler Therefore, the heat loss should be reduced when the heat insulation and heat pipe system of the boiler are damaged or leakage is discovered. The increase in noise from gas-fired steam boiler burners is mainly due to the closure of the valve or insufficient oil intake in the oil path, blockage of the oil filter, or because of low inlet temperature, high viscosity or oil on the pump. Too high temperature; oil pump failure; fan motor bearing damage; due to dirty turbine impeller, the equipment is too loud. This failure occurs when a gas-fired boiler is in use and is not easy to atomize (heavy oil) because of the high viscosity of the oil; it is also due to cyclone and jet The distance between the nozzles is inappropriate; in addition, because the burner is worn or dirty; it is also due to the excessive heating temperature of the spare fuel tank, resulting in steam pumping the oil pump out of the oil pump; or because the oil in the oil boiler is hydrated. Gas steam boiler feed water contains a variety of impurities and calcium, magnesium and other scaling substances, the boiler will inevitably expand. The thermal conductivity of the scale is very low, so once the surface is polluted by the hot surface, the exhaust temperature of the boiler will increase, and the heat loss of the exhaust gas will increase due to the increase of the thermal resistance. The experimental data show that the heat loss of waste gas will be increased by about 2%-4% when 1mm oxide is formed on the heating surface of boiler. The thicker the scale on the heating surface of the boiler, the greater the thermal resistance, and the lower the thermal efficiency of the boiler.
