Flue Gas Recirculation (FGR) is one of the most effective techniques employed in modern boiler systems to achieve low emissions of nitrogen oxides (NOx), a group of pollutants responsible for smog formation and acid rain. To truly appreciate the value of FGR and its widespread adoption in boiler technology, it's essential to delve into the underlying principles and its benefits.
1. Nitrogen Oxides (NOx) in Boiler Combustion:
When fuel is burned in boilers, several by-products are formed. Among...
Maintaining an industrial gas boiler is crucial to ensure its efficient operation, longevity, and safety. The cost for one year of maintenance can vary depending on various factors, including the boiler's size, its usage intensity, the region or country, and the specific maintenance tasks required.
Factors Influencing Maintenance Costs:
Boiler Size and Capacity: Larger boilers with higher capacity usually come with higher maintenance costs due to the increased number of components and the comp...
There are many factors that affect the safe operation of the boiler, including the boiler feed water. Adopting the boiler water supply system that meets the standard can avoid some failures and ensure the service life of the boiler. Focusing on boiler industry for more than 30 years, ZOZEN Boiler has accumulated rich project experience, and summarized some auxiliary equipment mainly included in boiler water supply system, hoping to be helpful to everyone.
Boiler water supply system main...
The 10-ton gas boiler recommended by ZOZEN Boiler is the WNS series. It is a shell wet-back three-pass fire tube structure. The flame burns in a large combustion chamber with slight positive pressure, which is fully extended, with low combustion heat load, high combustion efficiency, energy saving and consumption reduction, and more economical use. The use of corrugated furnace and threaded smoke tube in the boiler not only improves the heat absorption strength of the boiler, but also meets the ...
The outlet temperature of gas boiler is related to the rated working pressure, such as the outlet temperature of 95℃ at the rated working pressure of 0.7MPA and 115℃ at the rated working pressure of 1.0MPA. In daily use, it is a common problem that the outlet temperature of gas-fired boiler cannot be raised.
After summary, the reasons why the outlet water temperature of gas boiler can't be raised are as follows:
1. The set temperature is too low.
2. Whether the actual temperature is c...
Boiler heating is the main way of central heating in shopping malls, enterprises and residential areas. Many enterprises should consider the heating efficiency and heating area of boilers when choosing and using them, which has a certain relationship with the boiler model and capacity. As a professional hot water boiler manufacturer, ZOZEN Boiler takes the heating area of 5-ton boiler as an example to help users better understand the selection of heating boilers.
Calculate the heating area of a...
The working pressure of the boiler system should be economical and reasonable. Steam conveying system is an important connection between steam source and steam equipment. Steam distribution system must provide correct flow rate and correct pressure with less heat loss and less cost. In this paper, ZOZEN Boiler will explain how to determine the working pressure of the boiler system.
Theoretically, the working pressure of the boiler system depends on the highest pressure required by the s...
Why are there CO boilers? As the leading enterprise of industrial boilers, ZOZEN Boiler not only provides users with high-quality products, but also provides users with perfect installation services. Here are the main steps of hot water boiler pipeline installation: 1. The installation of water supply pipeline should start from the equipment connection end, extend outward based on the pipeline interface on the equipment, and pay attention to the installation under the heating pipe. Set the highe...
