  • 2020年春运与往年有啥不一样
    What is the difference between the 2020 Spring Festival and previous years

    From January 10 next year, the 2020 Spring Festival will be launched. This "periodic big migration" is earlier than previous years and will continue until February 18 for a total of 40 days. According to research, in the 2020 Spring Festival, the national passenger shipments will reach about 3 billion, a slight increase from the previous year. Spring Festival affects whether families can have a happy and peaceful Spring Festival. How is the 2020 Spring Festival different from previous years? Can returnees buy tickets to go home smoothly? How to do all the guarantees? The new changes in the "alternate ticket purchase" and "brush face pit stop" make people look forward to the 2020 Chinese New Year, which is the Chinese New Year in the early 8 years. The joy of returning home for the new year, and the application of new technologies such as brushing face into the station make people look forward to the upcoming Spring Festival. Due to changes in migration characteristics, ...

    Jiang Yi: Clean heating requires us to make good use of electricity

    Original title: Interview 丨 Jiang Yi: Clean heating requires us to make good use of electricity. Recently, it was hosted by the Tsinghua University Building Energy Conservation Research Center. The week-long 15th Tsinghua University Building Energy Academic Week ended. How to scientifically plan a clean heating path in northern China? How to integrate adjustment and transformation of urban energy system? During the academic week with the theme of "Low-carbon Energy and Clean Heating in Future Cities", there were several special seminars such as "electric heating development", "urban clean energy planning and technical approach", "thermoelectric and coordinated energy system model" and other seminars. Attract experts and representatives from related fields to discuss. "Clean heating requires us to further correctly understand electric heating, whether coal is transformed into electricity, whether it is based on the high efficiency of electric heating conversion, and its flexibility on the grid side and at the end of heating ...

    Shaanxi burners share the impact of steam boiler fouling?

    If the water of the steam boiler is not treated with soft water, it is easy to foul. What effect does fouling have on the steam boiler? Shaanxi burner tells you: 1. Waste of fuel and reduced thermal efficiency Fouling will cause the boiler's thermal conductivity Poor, once the steam boiler is scaled, the heat transfer performance of the heating surface of the steam boiler will be poor, and the heat released by the fuel combustion cannot be completely transferred to the boiler water, and a part of the heat will be taken away by the flue gas, which will cause the exhaust temperature. The increase in heat loss causes a large amount of heat loss, and the thermal efficiency of the steam boiler will decrease. In this case, in order to ensure the parameters of the steam boiler, more fuel will be added for non-combustion to increase the furnace temperature and flue gas temperature, which will cause waste of fuel. 2. Affecting the safe operation of steam boilers The thermal conductivity of boilers changes due to scale ...

  • 陕西配电柜的安装方法你知道吗?
    Do you know the installation method of Shaanxi distribution cabinet?

    The installation requirements of power distribution cabinets (boxes) in Shaanxi are: the power distribution boards (boxes) should be made of non-combustible materials; production places and offices with a low risk of electric shock can be installed with open-type power distribution boards; Poor processing workshops, castings, forgings, heat treatments, boiler rooms, woodworking rooms and other places should be installed with closed cabinets; in hazardous working places with conductive dust or generating flammable and explosive gases, closed or explosion-proof must be installed Electrical equipment; all electrical components, meters, switches and lines of the distribution board (box) should be neatly arranged, firmly installed and easy to operate. The bottom of the board (box) installed on the floor should be 5-10 mm higher than the ground; the center height of the operating handle is generally 1.2 ~ 1.5m; there is no obstacle within the range of 0.8 ~ 1.2m in front of the board (box) ...

  • 陕西配电柜供电时应了解什么知识?
    What should I know when powering a power distribution cabinet in Shaanxi?

    Shaanxi Power Distribution Cabinet Introduction When using diesel generator sets, it is unknown that the timely power supply of generator sets is also a university. Q: First, start the inspection of the solenoid valve. When the generator was running, people summed up a set of inspection methods of "one look, two listens, three touches, four smells". Listening at startup is an important step. Take the Cummins generator as an example, just press the start button and it will start after three seconds. Two "clicks" can be heard within these three seconds. Once the second sound is not heard, it is necessary to check whether the start solenoid valve is working normally. Of course, if the solenoid coil is blown, the generator cannot start of course. Second, check the battery pack. As the backup power is not often put into use, whether the generator can start normally depends on the maintenance of the battery. If the battery pack appears ...

  • 陕西燃烧器的分类有哪几种?
    What are the classifications of Shaanxi burners?

    Shaanxi burners can be divided into pulverized coal burners, oil burners and gas burners according to the fuel they burn. Folding pulverized coal burners are divided into swirl type and DC type. ① Swirl pulverized coal burner: It is mainly composed of primary air cyclone, secondary air regulating baffle (swirl blade or volute) and primary and secondary air nozzles (Figure 1 swirl pulverized coal burner) . It can be placed on the front, side or front and back walls of the combustion chamber. The air conveying pulverized coal is called primary air, which accounts for about 15-30% of the total air volume required for combustion. The pulverized coal air mixture is injected into the combustion chamber through a primary air nozzle of the burner. The other part of the air required for combustion is called secondary air. After the secondary air passes through the adjusting baffle (swirl blade or volute) of the burner, it forms a rotating airflow, which is combined with the primary air at the burner outlet ...
