At the same water temperature, the larger the excess amount of oxygen scavenger in water, the faster and more complete the chemical reaction. Under the same dosage, the higher the water temperature, the better the deoxidization effect. Under the same deoxidization effect, the higher the water temperature, the smaller the dosage.
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.
Industrial boiler is special equipment, the particularity and complexity determine that safety is its fundamental. In fact, the so-called safety door refers to the boiler explosion-proof door.
As a kind of special equipment, the safe operation of industrial boilers is the key point that every enterprise may pay attention to. Today, let’s talk about the normal water level in boiler operation.
During the normal operation, the steam drum water level maintains 0mm, and the allowable fluctuation range is ±30mm, with the maximum not exceeding ±50mm.
Different boiler types have different weights. The traditional four-ton coal-fired horizontal boiler in China is about 25~30 tons.
ZOZEN Boiler has two series of coal-fired horizontal boilers, which are DZL series and SZL series. The DZL series with the capacity of 4 tons weighs 25 tons, and the SZL series with the capacity of 4 tons weighs 32 tons.

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.
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℃.
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.
