1, continuous blowdown
Objective: continuous blowdown pot portion of the salt may be excluded substance dissolved in the water to maintain a pot containing a controlled amount of salt and water alkalinity, to prevent excessive concentration affects the quality of the boiler steam production.
When the changes take the initiative to adjust the steam pressure, due to the same reason, the vapor pressure return to normal speed slow, which is the downside. Master drum china boilers factory of the characteristics of the load properly adjusted to maintain a stable steam pressure is very useful. For example, when manually adjust steam pressure, such as steam pressure drop was found, indicating that the load is less than the amount of steam production boiler, the fuel should be promptly increased. The steam pressure drop stopped, indicating the amount of steam production in the load on the basis of the new equilibrium is reached. To revert to the original steam pressure, still need to increase fuel. By the same token, when steam pressure rises, to promptly reduce fuel until the steam stops rising and the pressure returned to normal.
Condensing steam boiler can be favored by many enterprises because of its energy-saving, environmental protection and tolerance, and has gradually become one of the most popular boiler products in boiler products. The heat-resistant and wear-resistant condensing steam boiler needs to produce a large amount of steam through water, so it is necessary to inject a large amount of water into the equipment during operation. Because the equipment requires strict operation of boiler water filling, it needs to be operated according to the standard before it can be used normally. The condensing steam boiler equipment should pay attention to when feeding water to the equipment and see the following brief description:
1: in order to prolong the service life of the boiler, the condensing steam boiler reduces the occurrence of precipitation in the furnace in order to prolong the service life of the equipment and reduce the occurrence of precipitation in the furnace due to the different properties of the different water quality and the different precipitated substances. Therefore, the use of water quality has certain requirements and can choose the applicable water quality, which can improve the service life of boilers and reduce the production of a large amount of water scale. There are certain requirements for the use of water is not any kind of water can be used, in order to effectively protect the service life of boilers should pay attention to the selection of water suitable for the water quality requirements. And the water used must be soft water that has been tested and treated so that it does not produce a large amount of water. The long-term accumulation of dirt in the boiler causes pollution to affect the quality of use.
2: there are relevant standards for water temperature control during the operation of condensing steam boilers. Users should pay attention to controlling the water temperature within the standard range in order to achieve good use without anomalies. If the water temperature is too high, the high expansion of the whole equipment will cause the pipe to leak, and the low water temperature will make the steam production not enough to meet the normal use requirements of the enterprise.
3: when adding water to a condensing steam boiler at the standard level, attention should also be paid to the standard water level, which should not exceed the height of the water mark in order to ensure safety in use. Higher than the water level will not only cause waste but also cause the equipment to expand. When the expansion reaches the limit of the water level, it will cause the water to spill out and waste or even shorten the service life of the equipment.
