  • What are the main factors related to the gas consumption of a gas-fired boiler? 2020-03-06
    Compared with the price of a traditional coal-fired boiler, the operation cost of a gas-fired boiler is relatively high. So, users need to consider the price and quality before purchasing a boiler. For a gas-fired boiler, the energy-saving performance is more important than the boiler price. One year is enough for a gas-fired boiler with good energy-saving performance to save the extra costs of the boiler proper. And, the gas consumption is an important indicator to measure the energy-saving performance of a boiler.
  • What reasons cause the increase of burner noise of a gas-fired boiler? 2020-02-21
    1. If the stop valve of the oil circuit is closed or the feeding of oil is insufficient and the oil filter is blocked, it is necessary to check that the valve in the oil circuit is open, the oil filter works normally and clean the filter screen of the pump. 2. If the oil temperature is low, viscosity is too high or the temperature of the oil fed by pump is too high, the oil temperature needs to be increased or decreased. 3. If the the domestic sewage treatment equipment oil pump breaks down, the oil pump is required to be replaced. 4. If the bearing of fan motor is damaged, it is necessary to replace the motor or bearing. 5. If the fan impeller is too dirty, it is required to be cleaned.
  • What are the characteristics of the pellet fuel used in biomass-fired boilers? 2020-02-13
    1. The fuel volume is 1 / 30 ~ 40 of the raw material volume after molding; 2. The specific gravity is 10-15 times of the raw material, and the moisture content is between 12% and 18% (the moisture content of coal is below 10-15); 3. The net calorific value can reach 3500-4500 kcal (the net calorific value of class II bituminous coal is 3700-4700 kcal / kg); 4. The ash content is less than 10% (the ash content of coal is more than 20%); 5. Volatile matter ≥ 65.62% (volatile matter of class II bituminous coal≥20%). 6. Biomass fuel belongs to renewable clean energy, which is the same as wind energy and solar energy. The biomass fuel is rich in resources, it can ensure the sustainable use of energy. 7. The sulfur content and nitrogen content of biomass fuel are low, the amount of SOx and NOx generated in the combustion process is low.
  • 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 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.
  • 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.
  • How to pick the right boiler for your needs? 2019-10-18
    There are so many options to weigh when looking for high efficiency boilers: hot water or steam, wetback or dryback, type of fuel, and more. However, there are a few key considerations to make when evaluating a new boiler for efficiency that will help you no matter what your other considerations may be. Look for a fan that can deliver a stable air supply, a burner and boiler unit that can produce low emissions, a design that maximizes flue gas velocity, smart pressure vessel design, and an efficient heating power to boiler surface ratio are just a few considerations to keep in mind. These simple but powerful design elements are hallmarks of solid construction and will add up to significant performance enhancements. Our team members are always available for consultation and can make specific recommendations when it comes to models once we know more about your needs.
  • How safe are water tube boilers? 2019-08-09
    Safety is always a top priority when working with industrial boilers, at least it should be. Fortunately, safety has become less of an issue with more modern water tube boilers. Compared to traditional fire tube boilers, water tube boilers are far safer, almost to the point where you don’t have to worry about a catastrophic explosion taking place.
