Evaporation capacity is below 4t/h and 4t/h boiler. Check water level gauge, steam pressure gauge, feed water thermometer, exhaust thermometer, steam flow rate calculation. Oil temperature, oil pressure, oil level indication, oil quantity calculation, furnace outlet smoke temperature indication. The boiler should also have oxygen content of flue gas, negative pressure of furnace, economizer inlet and outlet water temperature indication.

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.

How to improve the energy efficiency of industrial boilers, industrial boilers how to improve energy efficiency 1, focusing on the transformation of practicality (1) above to recover waste heat can be effectively used. For example: high temperature organic heat boiler flue gas, but the process does not require the production of steam and hot water, attention should be considered heated by flue gas waste heat recovery techniques combustion air. (2) improved gas boiler should focus on energy-saving technologies improve the automation level of combustion control, precise control of the combustion state. (3) Consider first the application of energy-saving technologies and sophisticated equipment. 2, considering the technical nature to further improve the thermal efficiency of industrial boilers, it is necessary to consider new energy-saving technologies and equipment. Advanced (1) energy conservation technology and equipment, difficult to implement. Such as: waste heat recovery heat exchanger and the new technology: heat pipe technology, the condensed waste heat recovery technology; new water treatment device: microbial fouling and electromagnetic processing techniques (e.g., hydraulics); combustion automatic control technology. (2) spraying pulverized coal combustion technology (stratified combustion mode and suspension-fired boilers) design, construction and operation of high demand management, oxyfuel technology, such as high temperature air combustion technologies require large investments. 3, forming a complete transformation handle (1) must be considered boiler energy saving, heat insulation of synchronization is complete, sealing, and improved methods of burning fuel adjustment, and the fuel air distribution system of the inverter, reduced nicotinamide tube improved resistance to treatment. (2) pay attention to clean the boiler heating surface, and providing technical improvements boiler water, slag, ash, etc., to ensure that the boiler has good heat transfer properties. (3) the necessary training for technical operations and daily management of energy-saving equipment.

Fuxin City, Liaoning Province, Liaoning provincial government to respond positively to national policies according to the latest requirements, increase the intensity of atmospheric pollutants have increased in terms of the number of personnel or subsidies. Now funds raised 24.08 million yuan to support the removal of loose coal and coal-fired boiler control project.

According to statistics, since the fall of 2017, a total removal of Fuxin coal-fired boilers 488 units, a total of 1020.085 tons of steam, subsidies for 21.08 million yuan. At the same time, actively carry out the bulk coal Fuxin treatment project, the replacement of energy-saving small boilers 2,000 subsidy capital of 300 million yuan.

And, Fuxin City, developed a series of measures to scrutiny. To strengthen the management of special funds to ensure the flow of funds security, Fuxin City, the boiler license, inspection report and environmental impact assessment procedures to establish a furnace of a file basic information, to complete the formalities boiler users comply with the removal of subsidies standards, timely payment of subsidies to users hands.

After the implementation of removal of loose coal and coal-fired boiler control project implementation, Fuxin City air quality of the environment and the urban fringe have been greatly improved. According to the survey, this year, the average concentration of PM2.5 Fuxin City 35 micrograms / cubic meter, improved 12.5% ​​year on year; PM10 average concentration of 67 micrograms / cubic meter, improved 17.8% year on year; air quality compliance rate of 81.6%, an increase of 4 %.
