Pump Suitable For Hot Water Boiler Water Circulation

(1) Open the inlet valve, close the steam outlet valve, start the feed water pump to fill the steam boiler furnace (should be softened water), the water level to the normal water level of the water level gauge, check whether the water level is stable, if the water level drops, check the steam boiler Whether the drain valve is closed is not tight.

After reducing the temperature of the boiler feed water, steam temperature but increased, what is the reason? Boiler feed water prior to delivery to the boiler, previously heated, can improve the boiler efficiency to a large extent. By high pressure feedwater heaters, water temperature greatly increased. There are two types of feed pump: pumps in front of the heater to the heater is referred to as a low pressure, after the pump at a high pressure heater called a heater.

Although now this equipment, mainly to provide the steam needed, but the choice is very diverse, as long as it is understood that during the time, it can be found, such as a steam boiler plant, is in the energy With some changes on the way, such as natural gas and the like, there is electrical energy, etc., are now leading to the boiler equipment, energy began to appear a lot of ways, allowing plants to be selected now. And this boiler equipment, began to have automated operations and control, so that the same people have more choices.

Recently, market supervision bureau issued the Notice on Strengthening the National Energy Board within the scope of the power station boiler piping material quality safety risk prevention and control (the "Notice"), to further enhance the quality and safety supervision and management of boiler tubes, effectively preventing security risks, protect the power production safety , as follows.

First, carry out the verification of boiler tubes

The electricity business, special equipment manufacturers to immediately organize boiler tube inspections, to verify whether the focus of the pipe to meet the technical conditions stipulated orders, including the source, size, quantity, quality certificates, raw material procurement contracts, procurement contracts and other piping components. For imported pipe material, but also the verification of the customs declaration, commodity inspection report (proof of entry inspection and quarantine of goods), combined with the production, inspection and testing during use and operation of the situation, in-depth investigation pipe quality boiler safety issues and risks.

Second, effectively prevent security risks

Boiler pipe quality and safety hazards or other problems threatening the security and stability of power station boilers, power companies, special equipment manufacturers to take practical measures immediately, the complete elimination of quality and safety problems; there are significant quality and safety problems, it should stop running generator sets , boiler or stop production and sales of the pipe elements, and replace the boiler pipe complying with relevant standards.

The actual boiler pipe manufacturing unit is unknown or if there are doubts, the relevant information or data can not be traced authenticity, power enterprises, special equipment manufacturers to immediately in accordance with industry standards, inspection and testing institutions have entrusted the appropriate qualifications for boiler tubes were identified test. Test results show that failed boiler or pipe quality does not meet the technical requirements stipulated in the order, power companies, special equipment manufacturers to eliminate hidden dangers in a timely manner or be replaced.

Third, strengthen the source of control boiler pipe

Special equipment manufacturing enterprises, power enterprises should strengthen boiler pipe source control, in strict accordance with the standard provisions of China's relevant laws and regulations and orders technical conditions agreed to carry out boiler pipe design and manufacturing, procurement orders, admission acceptance, inspection and testing, installation and commissioning work, resolutely eliminate substandard or counterfeit boiler pipes enter the field of electricity production; to strictly implement the special equipment safety supervision and management regulations, establish and improve the technical archives and long-term care, to ensure that relevant information can be traced back.

Special equipment manufacturing enterprises, power companies are finding there are significant quality and safety risks of boiler tubes, to report to the local market regulators, power management departments and the National Energy Board sent energy regulators, and to take effective measures to thoroughly rectification to ensure the safe operation of generators . Provinces, autonomous regions and municipalities and Xinjiang Production and Construction Corps Market Authority (Hall Commission) should work together with the same level of power management departments, the National Energy Bureau sent energy regulatory agencies and other units, the organization of supervision and inspection, supervision and hidden rectification, effectively preventing security risks.
