n2 inertization of watertube boilers

According to the central environmental supervision feedback on the issues raised in item 50: "Mudanjiang 108 wood processing enterprises, 69 there is the issue of illegal construction projects, companies supporting more than 114 n2 inertization of watertube boilerss for small hand-burning stove, black smoke very serious people to report complaints, "the rectification of the problem. Mudanjiang City, Heilongjiang Province, the municipal government attaches great importance to conduct a comprehensive renovation work for small coal-fired boilers.

The beginning of tasks to carry out, Municipal Environmental Protection Bureau of Mudanjiang City Center 108 existing wood processing enterprises in coal-fired boiler equipment to be checked. Inspection and found 69 illegal construction projects there is a problem, companies supporting more than 114 boilers for small hand-burning stove, black smoke is very serious. To date, there are 65 companies to complete the record, four enterprises waste industry. By Trade and Industry Bureau of Quality Supervision and verification, 114 sets of small boilers of this regulation in the wood enterprises, has completed the transformation units 62, cancellation, revocation 23 units, idle shutdown, waste industry 26, and removal of three. Wherein Yangming boilers zone 97 (where the 58 transformation is complete, the boiler cancellation, revocation table 21, the idle shutdown, industry waste boiler 18); boilers zone 12 (where the grid and transformation of the two, the idle shutdown the six, cancellation of Taiwan, has been demolished three); Dongan District 3 boilers (in which the transformation is complete for two, small boilers cancellation Taiwan); Xi'an area, Edmonton area each in Taiwan, the company has waste industry.

Next, the relevant departments will conscientiously implement the municipal government on Ecological Construction Decision deployment environment, learn from experience and practice fraternal units, work together to tackle, wood enterprises continue to consolidate and expand the results of pollution remediation, pollution prevention and determined to win the battle , to create the sky bluer, more green mountains, clear water and more beautiful environment, Mudanjiang modernization and make due contributions.

What are the requirements for select high and low altitude gas n2 inertization of watertube boilers?

Physics tells us that the higher the altitude, the lower the pressure, the thinner the air, the oxygen content will be reduced. So, for high altitude plateau, in the choice of gas boilers, what precautions do?

There are certain conversion relationships between MW (mw) of hot water n2 inertization of watertube boilerss and tons (t) of steam boilers. For example, a 0.7mw hot water boiler can be said to be a 1 ton hot water boiler, and a 4.2mw hot water boiler can be said to be 6 tons of hot water. Boiler, but mw must be the unit of hot water boiler, but can not say that 0.7mw hot water boiler is 1 ton steam boiler, the medium is different, the two boilers are completely different.

About steam n2 inertization of watertube boilers water hammer faults and solutions 1, boiler water hammer phenomenon a. Issued boilers and pipes at a certain rhythm crash, sometimes loud sound, accompanied by strong vibration water pipes or steam pipes. B. gauge pointer swings back and forth, consistent with the frequency of the vibration noise. c. In the water hammer severe, may lead to the respective connecting members, such as flanges, weld cracking, breakage of the valve. 2, the steam pipe Water Hammer process a. Reduced steam supply, close the main steam valve if necessary. b. Turn hydrophobic superheater header pipe and the steam trap on. c. drum level is too high, the sewage should be appropriate to maintain the normal water level. d. strengthen water treatment work to ensure water supply and boiler water quality, prevent priming. e. When the water hammer arrestor, and the frame status check pipes, flanges, etc., such as a warm-again without damage for the steam supply. 3, the process water pipe water hammer a. Open air valve on water pipe exclude air or steam. b. Enable alternate water supply pipe to the boiler feed water continues. If there is no backup line, take appropriate measures to deal with the fault processing pipeline. c. Check the water supply to the water pump and check valve, if the problem timely maintenance. d. Hold feedwater temperature equalization.
