  • What is the process load of an industrial boiler? 2020-01-17
    A process load is usually a high-pressure steam load. A process load pertains to manufacturing operations, where heat from steam or hot water is used in the process. A process load is further defined as either continuous or batch. In a continuous load, the demand is fairly constant - such as in a heating load. The batch load is characterized by short-term demands. The batch load is a key issue when selecting equipment, because a batch-type process load can have a very large instantaneous demand that can be several times larger than the rating of the boiler. For example, based on its size, a heating coil can consume a large amount of steam simply to fill and pressurize the coil. When designing a boiler room for a process load with instantaneous demand, a more careful boiler selection process should take place.
  • What is the system load of an industrial boiler? 2020-01-10
    System load is measured in either BTUs or tons of steam (at a specific pressure and temperature). It would be nearly impossible to size and select a boiler(s) without knowing the system load requirements. Knowing the requirements leads to the following information: The boiler(s) capacity, taken from the maximum system load requirement. The boiler(s) turndown, taken from the minimum system load requirement. Conditions for maximum efficiency, taken from the average system load requirement. Determining the total system load requires an understanding of the type(s) of load in the system. There are three types of loads: heating, process, and combination.
  • What impact will stack temperature have on boiler performance? 2019-12-27
    Stack temperature is the temperature of the combustion gases (dry and water vapor) leaving the boiler. A well-designed boiler removes as much heat as possible from the combustion gases. Thus, lower stack temperature represents more effective heat transfer and lower heat loss up the stack. The stack temperature reflects the energy that did not transfer from the fuel to steam or hot water. Stack temperature is a visible indicator of boiler efficiency. Any time efficiency is guaranteed, predicted stack temperatures should be verified. Stack loss is a measure of the amount of heat carried away by dry flue gases (unused heat) and the moisture loss (product of combustion), based on the fuel analysis of the specific fuel being used, moisture in the combustion air, etc.
  • What is a package boiler? 2019-11-29
    Package boiler is a boiler that had been fabricated and available as a complete package. The entire pressure parts have been assembled in the workshop and ready to be sent to the field or site where power plant is located. On the field/site requires only connection and integration of course work in electrical connections, water pipes, steam pipes and fuel piping system to operate. Package boiler is one of classification of boiler based on erection. Design package boilers in general are the type of Fire Tube Boiler and have made up shell and tubes. This type has high heat transfer both radiation and convection.
  • What is a combustion air preheater? 2019-11-22
    The combustion air preheater is definitely one of heat exchanger applications. Based on Figure 1 below, flue gas simply leaves steam boiler and passes via air preheater. The combustion air is passed through this equipment too to increase its temperature before being combined with boiler fuel. Because the temperature of combustion air is lower than the temperature of flue gas, combustion air receive heat transfer from flue gas through combustion air preheater in the process of convection heat transfer. The heat transfer make temperature of flue gas lower and consequently minimizes its heat loss and also decreases the air temperature to stack.
  • How often should steam boilers be replaced? 2019-09-06
    The service life of your industrial boiler is 15 years. Of course, there are a number of factors that may force you to replace your boiler before it reaches the 15-year mark. If there are obvious signs of wear and tear, you may not want to push the boiler much longer.
  • In what sectors are industrial steam boilers used? 2019-07-12
    The main sectors in which industrial steam boilers are used are: Food, in industrial bakeries or baby food (as an example) Textile, in rotary dryers Chemical, for reactors or storage Pharmaceutical, for the manufacture of medicines Cosmetics, for the production of perfumes and creams Stationery and printing, in drying tunnels The cement industry, for the manufacture of cement parts Oil, for the storage and distribution of heavy oils Wood, involved in the process of melanin production Hospitals and hotels, especially in the laundry and kitchen areas Automotive and surface treatment, for the final metal finishing.
  • What kind of steam does an industrial boiler produce? 2019-06-28
    The primary objective of an industrial boiler is the generation of steam. Steam is generated by heat transfer at a constant pressure. The fluid, which is initially in a liquid state, is heated, produces a variation in its phase and becomes saturated vapour. This saturated steam can then be used for different applications such as sterilization, fluid heating or electricity generation.
