  • How to deal with the low gas pressure in the gas-fired boiler? 2021-10-01
    As an effective tool in the era of environmental protection, gas-fired boilers are favored by all walks of life and widely used in food, paper, building materials, wine, chemical industry and other industries. With the increasing use of gas-fired boilers, there are more and more problems.
  • What is the boiler make-up water rate? 2021-09-24
    Make-up water rate refers to the proportion of treated water added to the boilers, steam turbine equipment and its thermal systems and participating in the circulation of steam-water systems in the boiler steam volume in the calculation period.
  • How to improve the CFB boiler efficiency? 2021-09-17
    The economizer of condensing gas-fired boiler can be installed in the flue of the current CFB boiler, to recovery the energy from the high-temperature flue gas, in order to reduce the fuel consumption. Also, the economizer helps to absorb the air pollutants such as the NOx and sulfur dioxide.
  • What is the difference between schematic diagram and wiring diagram of burner in the natural gas-fired boiler? 2021-08-27
    The burner of natural gas boiler refers to the burner for gas-fired boiler. Gas burners are divided into natural gas burners, urban gas burners, LPG burners and methane burners. The burner of natural gas boiler is just one kind of burner.
  • How much is a small coal-fired boiler? 2021-08-20
    The type and parameters of coal-fired boilers are the direct factors affecting the cost of a small coal-fired boiler. For example, rated capacity, rated steam pressure, rated steam temperature, feed water temperature, etc. With different parameters, the more requirements, the higher the price.
  • What are the correct ignition procedures for industrial coal-fired boilers? 2021-07-23
    The ignition of industrial coal-fired boiler needs to be operated steps by steps, and the ignition operation is different according to the specific model of industrial coal-fired boiler. Grates of industrial coal-fired boilers are usually divided into manual grates and mechanical grates. Here, according to the different grates, the correct ignition steps of industrial coal-fired boilers are introduced in detail.
  • What are the main reasons for the increase in exhaust gas temperature of gas-fired boiler? 2021-07-16
    Ash accumulation on the heating surface. The scaling and ash deposition on the water-cooled wall of the furnace and the ash deposition of the superheater, convention tube bundles, economizer and preheater can increase the thermal resistance of the flue gas, weaken the heat transfer, lessen the cooling effect of the flue gas and increase the exhaust gas temperature of the gas-fired boiler.   Too high excess air coefficient. Under normal circumstances, as the furnace outlet excess...
  • What is a low-pressure boiler? 2021-04-23
    Low-pressure boilers operate at a lower pressure and reach lower temperatures than high-pressure steam boilers. Water in low-pressure boilers is not heated beyond 250ºF, and the steam pressure does not exceed 15 psi (pounds per square inch).
