  • How to guarantee the successful and efficient shell boiler operation? 2021-03-12
    To guarantee the successful and efficient shell boiler operation, the user must: 1)Know the conditions, environment, and demand characteristics of the plant, and accurately specify these conditions to the boiler manufacturer. 2)Provide a boiler house layout and installation that promotes good operation and maintenance. 3)Select the control systems that allow the boiler to operate safely and efficiently. 4)Select the control systems that will support the boiler in supplying dry steam to the plant at the required pressure(s) and flowrate(s). 5)Identify the fuel to be used and, if necessary, where and how the fuel reserve is to be safely stored.
  • 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 is the special spray gun for pulverized coal boilers? 2021-02-19
    The special spray gun for pulverized coal boilers is a kind of equipment that atomizes fuel oil (light oil, heavy oil, residual oil, etc.) to make the fuel oil into UM-level particles. Through air distribution and ignition, the fuel oil can be sufficiently burned. It is widely used in the boiler industry.
  • 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 is the working principle of the automatic boiler water level controller? 2021-01-29
    The automatic boiler water level controller is mainly composed of hardware and software parts to complete the functions of the control system. The hardware part is mainly composed of the water level detection circuit, drive circuit, water level indication circuit, pressure automatic control simulation, manual control, etc. The software part is mainly composed of the programs written in assembly language.
  • What is the oil consumption per hour of a 2 tph oil-fired boiler? 2021-01-29
    The oil-fired boiler refers to the boiler fueled by oil, including the diesel, waste oil and other fuel oil. The oil consumption of the oil-fired boiler affects the economic operation of the boiler.
  • What are the basic configurations of the thermal oil heater system? 2021-01-22
    According to the differences in fuel and structure, industrial thermal oil heaters are mainly divided into the oil/gas-fired thermal oil heater and coal/biomass-fired thermal oil heater. The basic configurations of the thermal oil boiler system generally are as follows.
  • 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:
