To guarantee the successful and efficient shell boiler operation, the user must:
1)Know the conditions, environment, and demand characteristics of the plant, and accurately specify these conditions to the boiler manufacturer.
2)Provide a boiler house layout and installation that promotes good operation and maintenance.
3)Select the control systems that allow the boiler to operate safely and efficiently.
4)Select the control systems that will support the boiler in supplying dry steam to the plant at the required pressure(s) and flowrate(s).
5)Identify the fuel to be used and, if necessary, where and how the fuel reserve is to be safely stored.
Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell. Shell boilers may also be referred to as "fire tube" or "smoke tube" boilers because the products of combustion pass through the boiler tubes, which in turn transfer heat to the surrounding boiler water.
The efficiency of a coal-fired boiler depends on the loss of the boiler, the best efficiency in the boiler can be achieved if the losses are kept to the minimum. Since 50% of the losses are dependent on the fuel and ambient condition, the best efficiency can be achieved by properly tuning the other 50%, i.e. mainly carbon loss and dry gas loss.
As we all know, the stable operation of the natural gas boiler can significantly optimize the operation of the boiler, improve the efficiency of the boiler, and effectively reduce the operating cost of the boiler after effective maintenance. So, what factors will affect the stable operation of natural gas boilers?
Pickling is the main method for removing a large amount of oxidizing substances and corrosion products inside a gas boiler, and also has the effect of eliminating scale. The pickling process is usually carried out after 1-3 weeks of boiler operation.
The special spray gun for pulverized coal boilers is a kind of equipment that atomizes fuel oil (light oil, heavy oil, residual oil, etc.) to make the fuel oil into UM-level particles. Through air distribution and ignition, the fuel oil can be sufficiently burned. It is widely used in the boiler industry.
Many business units are in contact with low-nitrogen boilers for the first time, and they do not have a good grasp of how to operate correctly and effectively extend the service life of the boiler. ZOZEN Boiler specializes in the production of low-nitrogen boilers, summarizing the following three techniques for extending the life of low-nitrogen boilers, helping users to better operate low-nitrogen boilers.
