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...
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.
When it is found that the boiler steam pressure can't rise, the first thing we should do is to check whether the water pump of the gas-fired steam boiler works and how much the pressure of the water pump of the gas-fired steam boiler can reach. When installing the water pump of the gas-fired steam boiler, a pressure gauge is installed on the water pump. This is because, if the gas-fired steam boiler does not add water, it can be detected whether it is caused by the water pump.
With the continuous development of economy, as the main heat energy equipment, industrial boilers are widely used. This article discusses the calculation standard of boiler feedwater enthalpy value.
First of all, don't panic. According to the normal shutdown sequence, check whether the fuel, steam and water valves of gas-fired boiler meet the shutdown requirements.
Secondly, close the surface blowdown valve of the gas-fired boiler to prevent other faults of the boiler. Then, quickly close the main steam valve to prevent the gas boiler drum from losing water.
Thirdly, close the deaerator air supply valve, the main power switch and the natural gas valve. The air inlet of the gas-fired boiler burner should not be blocked to reduce the area of the air inlet, and the room ventilation should not be blocked to avoid the formation of toxic and harmful gases.
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.
When the water level is high, the quality of steam will drop. This is because the water level will enter the steam-water separator, and the water will slide out with the steam.
During the operation of automatic boiler water softener, the role of salt is to backwash sodium ion resin to prevent the sodium ion resin from being poisoned by iron, so the salt will not be destroyed during operation. Pay close attention to the salt content in the salt tank. As long as the salt is continuous, there is no requirement for the salt content. However, for good control, the amount of salt is generally about two-thirds of the salt tank, and then filled with water.
