The higher heating value of natural gas refers to the total heat released when a specified amount of natural gas is completely burned, including the latent heat of vaporization released by the condensation of water vapor in flue gas into water.
The lower heating value of natural gas refers to the heat released when a specified amount of gas is completely burned, the temperature of combustion products is the same as the initial temperature of natural gas, and the generated steam remains ...
Boiler parameters are the main indicators of boiler performance, including boiler capacity, steam pressure, steam temperature, feed water temperature, etc. Boiler capacity can be expressed by rated evaporation or maximum continuous evaporation. Rated evaporation is the amount of steam continuously produced per unit time under the specified outlet pressure, temperature and efficiency. The maximum continuous evaporation is the maximum amount of steam that can be continuously produced per unit time under the specified outlet pressure and temperature.
Manually close the fuel supply valve, stop the combustion, purge after the program enters, until the end of the purge, stop the program such as burning heavy oil, and enter the line sweeping stage before stopping the combustion, and purge with steam or light oil pipe; Generally, steam purging is used when stopping for a long time.
In the industrial boiler industry, it is generally divided into four grades: A, B, C and D according to the production qualification license grade, among which, when purchasing boilers, users often consider Grade A boiler manufacturers. What is a grade A boiler?
In the dairy industry, an efficient steam boiler is quite necessary to the dairy production process. The dairy steam boiler is critical milk processing equipment to transfer the raw milk to the high-quality of dairy products. Therefore, choosing a good dairy steam boiler is one of the most important decisions a dairy plant must make.
When you choose the dairy steam boiler, the first thing you shall pay attention to is the boiler shall meet the fluctuating load demands. Second, the boile...
Power boilers take the chemical energy stored in fuel, convert it to heat energy in the combustion process, and transfer that heat energy to water to produce steam. The transfer of energy from combustion gases to the water and steam is called heat transfer.
If the impurities in the boiler feedwater are not dealt with properly, carryover of boiler water into the steam system can occur.
Carryover can be caused by two factors:
Whether it's an industrial hot water boiler or an industrial steam boiler, they all depend on fuel to run. The process of heating is initiated as the burner heats or eventually evaporates the water inside of it. It's actually transported via intricate pipe systems.
Steam boilers transport through the pressure created by the process, while hot water boilers use pumps to move heat throughout the system. Eventually the condensed steam or cooled water returns back through the pipes to the boiler system, so the heating process can be initiated again.
As the boiler creates heat energy, a byproduct of the process — flue gases — are exited through a chimney system. Because of this, regulating the industrial boiler emissions is a very serious issue.
