  • 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 is the impact of excess air on efficiency? 2019-12-20
    In theory, to have the most efficient combustion in any combustion process, the quantity of fuel and air would be in a perfect ratio to provide perfect combustion with no unused fuel or air. This type of theoretical perfect combustion is called stoichiometric combustion. In practice, however, for safety and maintenance needs, additional air beyond the theoretical "perfect ratio" needs to be added to the combustion process - this is referred to as "excess air".
  • What are condensing boilers? 2019-12-20
    Condensing boilers can achieve up to 98% thermal efficiency, compared to 70%-80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies over 90% when the return water temperature is at 110 ºF or less; the lower the return water temperature, the higher the efficiency gain.
  • Signs you should replace your thermal oil system 2019-12-06
    1. Your existing system is inefficient Efficiency is key when it comes to plant heating. Utilizing efficient equipment can save your company a significant amount of money in the long run and it is better for the environment. If you know that your existing system is not as efficient as it could be and it is in need of repair, it may be worth looking into thermal oil system replacement. 2. Your existing system features helical coil technology Helical coils are common in thermal oil heaters from most manufacturers. But there are many reasons why serpentine coils are the better way to go when it comes to thermal fluid heating. Repairs to helical coils can be so expensive and time consuming that in many cases you are better off investing in new equipment – and it is well worth it to consider a new thermal oil system that features serpentine coil technology instead.
  • 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.
  • Understanding ASME Code: What It is and Why It Matters? 2019-11-22
    ASME code – also known by its longer name: ASME Boiler & Pressure Vessel Code – regulates the design, development, and manufacturing of boilers used in a variety of industries and applications. This code was developed by the American Society of Mechanical Engineers, an organization that has been around for well over 100 years and is focused on establishing safety codes and standards for mechanical equipment. Within the industrial heating industry, ASME code is the established standard that many pieces of equipment are built to. Heating systems that adhere to the specifications set forth by ASME code have been constructed according to guidelines intended to promote safety and quality. As such, heating equipment that is ASME code compliant has been thoroughly inspected to assure that it meets high safety and quality standards.
  • What is the mechanism of economizer? 2019-11-15
    Economizer is one of steam boiler’s equipment which is used to heat feedwater before it is supplied into steam drum. Economizer is the heat exchanger equipment to increase boiler efficiency by absorbing heat recovery of flue gases. The lower temperature of flue gas out from stack, the heat loss will be less and the fuel which is needed to convert water into steam will be also less in certain circumstances. So it can be said that economizer can save the fuel efficiently.  Economizer will make temperature of feedwater higher, so steam boiler can produce steam easily.
