The natural gas testing of the boiler is to measure various thermal performance parameters of the boiler in a stable working condition (that is, in a normal combustion state), so as to judge the energy efficiency of the boiler. Natural gas testing can determine the thermal efficiency of the boiler, determine the size of each heat loss of the boiler, analyze the causes of each heat loss and seek ways to reduce the heat loss, so as to improve the energy efficiency of the boiler. What is the testin...
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...
Natural gas boiler heating is an important livelihood project, and the design of natural gas boiler heating is related to whether the heating is safe, stable, efficient and environmentally friendly. As a professional supplier of natural gas boilers, ZOZEN Boiler has summarized a heating design solution for natural gas boilers.
The working principle of natural gas boiler heating is that the circulating water is transported to the boiler inlet by the circulating water pump, and after bein...
Sulfur dioxide is a common sulfur oxide, which dissolves in water to form sulfurous acid. When oxidized in the presence of PM2.5, it will quickly and efficiently generate sulfuric acid and cause acid rain. Therefore, the concentration of sulfur dioxide in boiler flue gas directly affects the environment, and is valued by many parties.
How is sulfur dioxide produced in boiler?
The principle of how sulfur dioxide is produced in boilers using different fuels is different. Sulfur in solid ...
Before degassing and dehydration, boiler parts must be checked, and detailed inspection items are as follows:
1.Burners work well, combustion is stable and combustion load change can be controlled freely.
2.Auxiliary such as FD fan, ID fan, oil system equipment and so on shall do cold test and run normally.
3.Lubricating oil shall be full filled in all bearing boxes and oil cups.
4.Inspection of safety accessories and protective equipment:
a) The needle valve or the stop valve in the pressu...
Tap water or water with a lot of impurities will cause the magnesium ions and calcium ions in the water to form some white precipitates when heated at high temperature, causing scaling problems and reducing the heat transfer efficiency of the boiler. Boiler operation safety brings hidden dangers, even shutdown.
The specific reason why softened water must be used in hot-water boilers is that it will not produce scale in the process of use, so that potential safety hazards of boilers can ...
Before coking and boiling, check boiler parts detailedly. Inspection items are as follows:
1. Before coking and boiling, chain grate should be cold test run again and continuous running time shall not be less than 24 hours.
2. Ignition door can be opened flexibly, coal gate can be lift and dropped conveniently, coal gate left and right side is of the same distance to grate, and ensure the material layer thickness on both sides of the furnace is equal. If distance is not equal, it can be adjust...
1. After boiler body, economizer, air pre-heater, dust collector, etc are in place and installed, connect FD fan, ID fan, etc according to drawing and then connect corresponding flue gas duct. After fan in place, alignment between foundation and equipment base should be conducted with parallels. Fan position alignment should center on a shaft, central elevation deviation and vertical and lateral central line positional deviation should be 10mm or less and fan spindle should be in level state. Th...
