  • What are the biomass pellets for a biomass-fired boiler? 2020-04-24
    Biomass fuel can be applied to a biomass-fired boiler by treatment and compression molding. Commonly used are straw particles, rice husk particles, wood particles, sawdust particles, peanut rod particles, sugar aldehyde residue particles, palm shell particles and so on.
  • What are the characteristics of gas-fired boilers? 2020-04-24
    1. The control system is equipped with a special computer controller, which makes the boiler running clear and easy to operate. 2. The burner is controlled by full-automatic program, and in case of failure, the burner stops automatically. 3. The boiler body is designed with reasonable structure, and the top is equipped with air vent. The boiler works under normal pressure and is far away from explosion danger. The full wet back three-way structure and corrugated tank design are adopted. The flue gas process is long, the temperature of exhaust gas is reduced, the heat transfer coefficient is increased, and the equipment life is prevented from being reduced due to the expansion and contraction of metal.
  • What is the calculation method of the circulating water volume of a coal-fired hot water boiler? 2020-04-10
    The coal-fired boiler refers to the boiler uses various types of coal as fuel and converts the heat of coal to steam or hot water. There are generally two calculation methods of the circulating water volume of a coal-fired hot water boiler. One is to calculate the hourly water volume of one square meter and the other is to calculate the design parameter volume of every ton. As for the make-up water volume of this type of boiler, it is usually calculated as 1% to 3% of its total circulating water.
  • How is the dry bottom hopper formed in an industrial boiler? 2020-04-10
    The dry bottom hopper is formed by bending the lower part of the water wall of the front and rear walls inward. The main function is to gather, cool and automatically discharge ash. It is also convenient for the connection and sealing of the lower header and the ash well.
  • What is oil freezing point of industrial boilers? 2020-04-03
    Fuel freezing point is the temperature at which the fuel loses fluidity. It is an important index that indicates the fuel flows at low temperatures. It often refers to the maximum temperature at which the oil surface remains stationary within 1 minute. The higher the fuel freezing point, the lower the low-temperature fluidity. When the oil temperature is below the freezing point, it cannot be transported in the pipeline.
  • Does the biomass-fired boiler need to be shut down for maintenance? 2020-04-03
    Biomass-fired boilers need to be shut down for maintenance. Proper maintenance can reduce the damage to the boiler caused by continuous work. Firstly, it is necessary to cut off all power to prevent being struck by lightning. In addition, dust, limescale and carbon deposits should be cleaned up to prevent rust and corrosion of the boiler.
  • How to select a burner for the gas-fired thermal oil heater? 2020-03-20
    The selection of a burner of the gas-fired thermal oil heater should be determined according to the boiler proper structure and fuel characteristics and in combination with the actual conditions and requirements. In addition, this kind of boiler can adopt a waste heat recovery device to improve thermal efficiency and reduce heat energy loss.
  • What is the theoretical daily coal consumption of a set of 20 tph coal-fired chain grate steam boiler 2020-03-13
    Coal-fired boilers refer to boilers that use various kinds of coals as fuel and convert the heat value of coals to steam or hot water. Some specific parameters should be provided to calculate the theoretical coal consumption of a set of 20 tph coal-fired boiler. If the rated steam pressure is 1 MPa, the heat value of coal is 7000 kcal / kg, the boiler inlet water temperature is 20 ° C, and the boiler thermal efficiency is 80%, the daily coal consumption is 50-56 tons.
