  • Should I turn my oil boiler off when my oil tank is being filled? 2019-07-19
    Yes, it is recommended to turn your boiler off whilst the tank is being filled and to leave it off for a short period afterwards of up to 30 minutes. This will ensure that any sediment that has settled on the base of your tank is not stirred up and drawn into your fuel line.
  • What is a fire tube steam boiler? 2019-07-05
    A fire tube steam boiler is a boiler where the combustion gases from the burner are channeled through tubes that are surrounded by the fluid to be heated. The boiler body is the pressure vessel and contains the fluid. In most cases, this fluid is water that will circulate for heating purposes or become steam for use in processing. Each set of tubes through which the combustion gas passes, before making a turn, is considered a "step". Consequently, a three-step boiler will have three sets of pipes with the outlet located at the rear of the boiler.
  • How does a water tube steam boiler work? 2019-07-05
    In a water tube steam boiler, unlike a fire tube, water circulates inside the tubes. The heat that is generated and the combustion gases that surround the tubes heat the water that circulates inside them. Many water-tube boilers operate according to the principle of natural water circulation. The capacity of this type of boiler can be enhanced by increasing the number of tubes in the boiler.
  • What is a water tube boiler? 2019-06-06
    Any boiler where the products of combustion flow on the outside of a tube with the heat transfer media on the inside.
  • What are precautions to be carried out at Start in Steam Boilers? 2019-05-23
    1. Hydraulic should be carried out at a defined pressure before the start of a boiler.2. Check if the pump inlets are open at the start of a boiler.3. Install an automatic ash removal system such as rotary valves in a boiler so as to prevent the accumulation of ash in a furnace or other equipment. The accumulation may result in the blockage or excessive heating of boiler parts resulting in its failure.4. Pump priming must be done at the start of the boiler.5. All loose and wrong connections must...
  • What are the phenomena of coking on the circulating fluidized bed boilers? 2018-11-23
    The bed temperature rises sharply. Oxygen levels go down and sometimes drop to zero. The electric current of primary air fan is less and wind pressure of air compartment is higher. Negative pressure of furnace is increased while the electric current of induced draft fan is reduced. The slag discharge is difficult or unsuccessful. When appearing bed clinkering, the bed temperature and bed pressure will be uneven distributed and not at normal condition; the measuring point of part bed tempe...
  • What is difference between thermal oil heaters and steam boilers? 2018-08-30
    1. They are all a heat conversion device. The heat transfer medium they use is different. The water used in the steam boiler is heated to become steam. The heat transfer medium of thermal oil heater is heat medium oil. The heat is transferred to the heated substance by the heat medium oil.2. When a higher heating temperature is required, such as 280 degrees, the steam pressure of the steam boiler should reach 7MPa or more, and the process piping and heat exchange equipment must also withstand the same pressure. The equipment cost is high and dangerous. Thermal oil heater provides a temperature above 280 degrees, but the pressure is lower than 1MPa.3. The temperature of thermal oil heater can be accurately controlled within 3 degrees and the temperature of the steam changes greatly.4. Thermal oil heater is used alone, the exhaust gas temperature is higher, and the thermal efficiency is lower than that of the steam boiler. However, if used in conjunction with a steam boiler, the
