  • What if the fully automatic thermal oil heater catches fire? 2020-12-25
    If the hot oil pump of the fully automatic thermal oil heater is suddenly damaged and stops working during the operation, the boiler circulation will be blocked. If the fuel is still burning to make the oil temperature keep rising, it will cause the coking of the hot medium oil which is easy to cause a fire. If the fully automatic thermal oil heater catches fire due to the power cut during the operation, the boiler operator should quickly put out the fire in the furnace to stop the fuel from burning, and blow a large amount of cold air into the furnace to lower the temperature.
  • What are the precautions for using the hot medium oil? 2020-12-25
    The hot medium oil of the thermal oil heater should be tested regularly to measure and analyze the physical and chemical indicators such as the residual carbon, acid value, viscosity, flash point, melting point and so on, so as to know the quality changes in time and analyze the reasons for the changes. When the acid value exceeds 0.5mgKOH/g, the viscosity change reaches 15%, the flash point change reaches 20%, and the residual carbon (mass fraction) reaches 1.5%, it indicates that the performance of the hot medium oil has changed. Therefore, the user needs to regularly add the new heat carrier when using the hot medium oil to keep the residual carbon in the system stable.
  • What is the working principle of dust removal of coal-fired boilers? 2020-12-25
    The flue gas first enters the cyclone dust collector which acts as a primary dust collector to make the large dust particles in the flue gas settle down. The cyclone dust collector is a dust removal device which uses the centrifugal force generated by the cyclone flow to separate the dust particles from the air flow. Afterwards, the flue gas enters the wet scrubber dust collector which is a circular-type cylinder. The circulating water enters the dust collector from the upper overflow tank to form a uniform water film on the inner wall of the dust collector. The flue gas is induced tangentially or spirally from the lower part of the cylinder and rotates in the cylinder. Under the influence of the centrifugal force, the dust particles are separated from the flue gas and then the flue gas is also spirally led out from the top of the cylinder. The dust particles are thrown to the water film, transferred to the bottom and finally discharged from the dust port.
  • What are the energy-saving measures of the natural gas fired boiler? 2020-12-18
    Boiler is a piece of equipment with large energy consumption. Therefore, both boiler manufacturers and purchasers regard energy conservation as an important indicator of boiler performance. The daily energy-saving measures of the natural gas fired boiler are mainly as follows.
  • What are the differences between the vertical and horizontal gas-fired boiler? 2020-12-18
    The vertical type and horizontal type are the two main types of boiler. The vertical gas-fired boiler has small volume and is suitable for small workshops or small production enterprises. It is often used in the fields of hot water and heating. The horizontal gas-fired boiler has larger volume with a wider application range than the vertical gas-fired boiler.
  • What are main pieces of auxiliary equipment of coal-fired boilers? 2020-12-11

  • How can gas-fired industrial boilers achieve low-NOx emission? 2020-12-11
    Gas-fired industrial boilers are high-efficiency, eco-friendly and energy-saving, and they play an important role in the production-oriented enterprises. Due to strict requirements for pollutant emissions, enterprises often attach great importance to the emission performance of boilers.
  • What are the installation requirements for the circulating pump of the thermal oil heater? 2020-11-27
    The thermal oil heater, also called the organic heat carrier boiler, is a kind of once-through boiler developed based on the forced circulation design concept. With gas, oil or coal as the fuel and heat conducting oil as the medium, the thermal oil heater adopts the thermal oil pump to force the medium conducting the circulation in the liquid phase. The medium transfers the heat energy to the heating equipment and then returns to the furnace for being reheated. The thermal oil heater has the advantages of high-temperature and low-pressure heating and precise control of the medium.
