  • What are the advantages of shell boilers? 2021-03-12
    1) The entire plant may be purchased as a complete package, only needing securing to basic foundations, and connecting to water, electricity, fuel and steam systems before commissioning. This means that installation costs are minimised. 2) This package arrangement also means that it is simple to relocate a packaged shell boiler. 3) A shell boiler contains a substantial amount of water at saturation temperature, and hence has a substantial amount of stored energy which can be called upon to cope with short term, rapidly applied loads. *This can also be a disadvantage in that when the energy in the stored water is used, it may take some time before the reserve is built up again. 4)The construction of a shell boiler is generally straight forward, which means that maintenance is simple. 5)Shell boilers often have one furnace tube and burner. This means that control systems are fairly simple. Although shell boilers may be designed and built to operate up to 27 bar, the majority operat
  • What are factors affecting the coal-fired boiler efficiency? 2021-03-05
    The efficiency of a coal-fired boiler depends on the loss of the boiler, the best efficiency in the boiler can be achieved if the losses are kept to the minimum. Since 50% of the losses are dependent on the fuel and ambient condition, the best efficiency can be achieved by properly tuning the other 50%, i.e. mainly carbon loss and dry gas loss.
  • What are the matters needing attention when discharging gas boiler? 2021-02-12
    For a boiler to operate stably and efficiently, all links must be properly coordinated without making mistakes. For gas-fired boilers, it is necessary not only to have softened water treatment facilities, but also to carry out regular sewage discharge, which cannot be ignored.
  • What are the common combustion methods for boiler equipment? 2021-02-12
    The combustion method of the boiler equipment is also a factor that the majority of users will consider when selecting the boiler. Depending on the combustion method, the boiler structure and boiler room layout will be different.
  • What is the gas consumption per hour of a 1 ton natural gas boiler? 2021-02-05
    Gas consumption per hour of natural gas boiler = boiler thermal efficiency / natural gas calorific value / boiler efficiency. The higher the efficiency of boiler use, the less gas consumption, which has inverse relationship between the two. Boiler efficiency has become a key point in assessing boiler quality.
  • What are the bad effects of the impurities in the boiler feedwater? 2021-01-15
    If the impurities in the boiler feedwater are not dealt with properly, carryover of boiler water into the steam system can occur. This may lead to problems elsewhere in the steam system, such as:
  • What is the working principle of forced circulation boilers? 2021-01-08
    According to the power of water or steam circulation, boilers can be divided into natural circulation boilers, forced circulation boilers, once-through boilers and combined circulation boilers.
