A firetube boiler can react very quickly to load changes due to the fact that it has a large volume of stored energy in the form of hot water and steam.
Conduction oil, commonly known as hot oil or heat transfer fluid, is an integral component in a broad range of industrial applications that require the transfer of thermal energy. This specialized fluid functions as an intermediary that carries heat from one point to another within a closed-loop system, ensuring the even distribution of heat across various machinery and equipment. Often, these oils are utilized in industries such as chemical processing, petrochemical plants, and manufacturing to...
Proper shutdown procedures are crucial for ensuring the safe and efficient operation of a coal-fired steam boiler. The following steps should be followed when shutting down a coal-fired steam boiler:
1. Reduce the load: Before shutting down the boiler, the load should be reduced to its minimum level. This will help to prevent sudden drops in pressure and temperature, which could cause damage to the boiler and its components.
2. Shut off the fuel supply: The fuel supply to the boiler should be ...
Boiler economizers are devices that help to improve the efficiency of industrial boilers by recovering heat from the flue gas and transferring it to the boiler feedwater. In this article, we will explore how boiler economizers work and the benefits they offer. We will also introduce ZOZEN's boiler and economizer solutions that can help improve the energy efficiency of your industrial operations.
How Do Boiler Economizers Work?
A boiler economizer is essentially a heat exchanger that recovers w...
It depends on the system of the gas boiler, the boiler water temperature at 60-90, 90-150 and 70-130 can achieve better energy-saving effect.
Energy-saving devices such as condensers are added to ZOZEN gas-fired hot water boiler. The waste heat is used to increase the water temperature of the gas-fired boiler. The rated inlet temperature is 70℃, and the exhaust gas temperature is reduced, so that the thermal efficiency of the boiler is increased to over 98%.
Different steam pressures correspond to different steam temperatures.
1. The steam temperature of low-pressure boiler is mostly saturation temperature or not higher than 400℃.
2. The outlet pressure of medium-pressure boiler is 3.8 ~ 5.4 MPa, and the commonly used steam temperature is 450℃.
3. The outlet pressure of sub-high pressure boiler is 5.4 ~ 9.8 MPa, and the common steam temperature is 540℃.
In the process of the development of national economy, the importance of boilers is self-evident. The so-called boiler is a device that uses the heat energy released by fuel incineration to heat water or other media, so as to obtain steam, hot water or other media with specific parameters (temperature and pressure).
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.
