water boiler tea

First, when the need for boiler pressure test? 1, the newly installed boiler when put into operation. 2, more than a year boiler outage and resume operation. 3, boiler, pressure member after significant repair or replacement, such as the number of water wall tubes in the replacement number of more than 50%, superheater, reheater, economizer other group member replacement, a significant repairs performed drum Time. 4, severe boiler overpressure 1.25 times the working pressure up to and above. 5, when a large heating surface area of ​​the boiler water after severe deformation. 6, according to operation, safety and reliability of equipment operation when there is doubt. Second, the method of pressure testing a boiler water pressure test should be carried out when the ambient temperature is higher than 5 ℃, antifreeze measures must be less than 5 ℃. 2, the water pressure test should be maintained above the ambient dew point temperature, to prevent surface condensation boilers, water seepage and the like will not occur closely confusion, difficulty increases inspection; but it should not cause high temperature to prevent vaporization (so difficult to find the leak) and excessive temperature stress, usually 20 ℃ ~ 70 ℃. 3, the water is full, pressure is gradually increased to 0.4MPa, namely a tight check, if necessary, be tightened once the flange, and hand Manhole cover bolt hole. 4, water pressure test, pressure should slow down, when the pressure rises to the pressure of work, should be suspended boost, check for leaks or anomalies, and then boosted to the test pressure for 20 minutes, if the pressure It did not decline, that is, down to the working pressure checked. 5, find any leaks should cook the recording, in order to reduce the time to repair the atmospheric pressure.

We learned that recently, the city of Wuwei in Tianzhu county government announced that it will carry out a comprehensive coal-fired boiler demolition "clear" action aimed at remediation efforts to increase coal-fired boilers, and resolutely fight pollution control tough fight, complete coal-fired boilers out of the grid, clean energy transformation of the task of governance and compliance. The task of governance staff, shimenzhen government, Hua Temple town government organization done by the Bureau of Wuwei City, the ecological environment will Tianzhu Branch, and Hua Temple shimenzhen government and town homes for the elderly failed fork Station coal-fired boilers were concentrated tear down. To continue to improve the air quality of the environment, protect the health of the people made great contributions.

Tianzhu County will further promote the comprehensive improvement of coal-fired boilers, and through the elimination of the demolition, clean energy transformation, environmental compliance management, etc., with the completion of the internal area of ​​coal-fired boiler remediation tasks, achieve discharge standards in all coal-fired boilers. Meanwhile, the industrial park central heating, phasing out central heating, and for 10 tons of steam coal-fired boilers in the gas pipeline network coverage.

Up to now, Tianzhu County by incorporating central heating, clean energy transformation, compliance management, has completed the renovation of 74 coal-fired boilers. The remaining four coal-fired boilers in Tianzhu Force has developed a program of clean energy for heating reconstruction project, planned in June renovation, completed in August.

Whether the boiler has to warm Notes boiler and boiler with HE detergents, it is an important product and one of the main keyword site, so the learning requirements, to achieve the full extent, and does not omit any of its knowledge . So, based on this specific requirement, then, is to proceed immediately to carry out this work, better improve learning efficiency. 1. Is there a corresponding boiler detergents? Boiler cleaning, it is possible to use detergents, but to use special detergents boiler, so as to ensure a good boiler cleaning effect. So, on this issue, the answer is yes. Further, on the particular type of detergent, M-1 type is that a security detergents, which is a scale remover for boilers, having a good cleaning effect and high cleaning efficiency, short time scale solution, safe and easy storage and transportation and, in addition to be used in the boiler, the heat exchanger may also be used. 2. The power boiler is whether the power boiler? Power boiler, which is included in power boilers, and from a professional standpoint, as long as a pressure, temperature of the steam or hot water boiler teas, power boiler can be considered. So, on this issue, you can get the answer is, not power boilers power boilers, power boilers is a power boiler. 3. What is the difference between Class B and Class C boiler is? Boiler with underfloor heating, what are the considerations? The difference between B and C class boiler, the boiler according to manufacturer box production technical personnel, which is the main difference in the operating pressure and the amount of evaporation, or that the operating pressure and thermal power. Notes boiler with underfloor heating, which is specifically as follows: (1) shall be installed in accordance with the original design of the boiler can not be used under water and on the return of this form, although with a lower back on the next time compared to the temperature difference in the water the difference is not great, but the situation will improve exhaust gas temperature and boiler efficiency. (2) the circulation pump connection is withdrawn water into the boiler water supply, so that the pump pumping water temperature is relatively lower. (3) no need to take the bypass, because the system does not natural circulation. 4. boiler feedwater oxygen Is it important? It can be omitted? Boiler feed water, which typically contains oxygen, such as oxygen into the boiler, the boiler will in some parts or parts subject to corrosion, and thus, affect the normal use of the boiler, and shorten the life of the device, therefore, the need for oxygen work boiler feed water, but also to be taken seriously and can not be omitted.

The high-function incinerator which is fully matched with the boiler is used for overall active conditioning, which makes incineration abundant, saves fuel, reduces pollution, selects ultra-fine glass cotton with high thermal insulation function, and reduces the heat dissipation loss, and the heat loss is reduced by using ultra-fine glass cotton with high thermal insulation function. The intelligent energy-saving control system is used to control the boiler and water supply, heating, automatic water temperature system, and adjust the fuel supply with different load, so as to save more energy. The method of installation is all fast-mounted boilers, small oscillation, no special requirements for the foundation, no need to anchor the ground bolt, the device is simple and easy to operate.
