  • How is steam produced in an industrial boiler? 2019-06-21
    Water, which is the primary fluid inside the closed metal container of the industrial boiler, is heated to an atmospheric temperature and a pressure higher than the external one. Once the steam is generated, it advances through the pipes.
  • 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.
  • How to choose heat fluid boilers? 2018-09-29
    For the selection of heat fluid boilers, first step is to determine several parameters: thermal power in the process, the oil temperature, and the use of waste heat.There are several methods for determining the boiler's thermal power:1. Calculation. According to the specific heat capacity of the material to be heated, the heating temperature difference, the processing amount per unit time, etc., the thermal power is equal to the product of the above three points, and the calculation result considers a certain margin amount as the boiler capacity.2. The sum of thermal power in the process equipment can also be used as the basis for the heat power.3. Refer to the experience of the same industry to increase or decrease on the basis of peers.4. If steam heating is used, it can be converted into heat transfer oil of the same tonnage and the capacity is appropriately reduced.The determination of the temperature of the heat transfer oil can be determined according to the characteristics of th
  • How to deal with too much damage of the dust collecting cloth bag of the biomass-fired boiler? 2018-07-12
    Question details (Performance):Dust collecting cloth bag damages a lot. Answer: The cause of the problem: As the biomass-fired boiler fuel moisture is high, and bag material is general PPS, which will reduce the base fabric of the bag in the case of high temperature, high humidity, hydrolysis, oxidation, and cause damage; In addition, the fuel moisture is high and it cannot be completely burned in the furnace, so it burns in the dust collector, which is also an important reason for the damage of the cloth bag.Troubleshooting:(1) Design by full consideration of high fuel moisture, choosing the appropriate induced draft fan, if the existing design is not enough then consider change the induced draft fan.(2) If induced air volume is sufficient, a proper distribution of the first and second wind should be considered. Generally, the fuel with high moisture and light quality such as wood chips, straw and wheat straw hood, the secondary air volume should be increased. For bark, miscellaneous
  • How to solve the phenomenon of superheater explosion in circulating fluidized bed boiler operation? 2018-07-12
    (Question Details) Specific Performance:The pipe of superheater bursts in circulating fluidized bed boiler operation.The bed pressure indicator fluctuates little. Answer:  causes of failure:(1) Design Factors.(2) Manufacturing process, installation and maintenance quality.(3) The temperature control device is unreasonable or does not work properly.(4) Effect of operating conditions on overheating and explosion of superheater. Troubleshooting:(1) Report the fact to operator on duty and require operating the boiler in low load.(2) When the overheat damage is serious,please report it to operator on duty and require stoping the boiler immediately to prevent blowout of the near pipes.(3) Adjust the steam temperature as much as possible within the normal range.(4) If the superheater tube is not damaged badly, it has little effect on the temperature level of the steam, and it can be allowed to run in a low load range for a short period of time.
