1, absolutely safe and reliable operation. The biggest advantage of non-pressure boiler is not running under pressure, without any risk of explosion.
2, save steel, to simplify the process. No less demanding on the material pressure boiler, furnace in addition, cheaper to rest with ordinary carbon steel material, a welding process using fillet welds can meet the strength requirements, saving the solder material, and simplifies the process.
3, it is well known, the main boiler scale sulfates and silicates, both types of scale with the continuous evaporation of the water solubility decreases to a certain extent (saturation concentration) after precipitation. Perennial non-pressure boiler water temperature is maintained at about 95 deg.] C, of less than the saturation temperature limit, scale is difficult to form. Therefore, no pressure boiler fouling also has the advantage of easy, so that unnecessary water treatment device omitted.
There are many business units to be able to save more spending often treated boiler manufacturers in mumbai water will take unscientific methods and tools in boiler water treatment process used, equipment, etc. also do not comply with the relevant provisions, For example, "three noes" of electronic instruments and antifouling agent scale.
Before coming heating season, Pinggu and Yanqing, Miyun three areas have been completed six large coal-fired boiler manufacturers in mumbai clean energy transformation, involving a total of 1660 tons of steam, residential heating area of about 900 square meters, in order to promote the city's urban focus heating basically clean heating to make a strong contribution.
It is reported that, in addition to this rural area south of the coal-fired boiler house for reasons of space, and the remaining five of the original coal-fired boiler room facility will be retained as an emergency backup. Pinggu District-Valley heating plant boiler clean energy transformation project has been debugging equipment, the boiler room of the original four coal-fired boilers, a total of 400 tons of steam, heating an area of about 2.5 million square meters, the new 3 sets of 100 tons of steam gas boiler is equipped with a heat pump.
Also, according to plan, City Management Committee led the development of the annual Yajian coal and clean energy facilities construction program to focus on the northern region, enhance power supply, gas supply capacity, promote Plains natural gas pipeline "town pass" to protect coal demand for clean energy. The basic realization of the city's plains village "No Coal", the phasing out of bulk coal sales within the region transformation of the industry and commerce department for bulk coal sales cancellation of registration in accordance with law, in principle, be issued a new business license. For failure to implement clean heating in winter 2018 and not included in the annual village "coal to clean energy" program, full implementation of quality coal instead.
Reduction of carbon dioxide, sulfur dioxide emissions
Pinggu District Management Committee, according to the person in charge, Riverside, Xia Xing Coal Valley and heating plant is heating an area of 7.416 million square meters, of which the heating plant heating Riverfront area of 4.1 million square meters, the Xingu heating plant heating an area of 2.808 million square meters, summer Coal heating plant heating area 508,000 square meters.
By upgrading "coal to gas", three heating plants meet emission standards Beijing local standard NOx emissions of less than 30 mg / standard cubic meter, while the amount of coal Yajian 160,000 tons per year, greatly reduce emissions of carbon dioxide, sulfur dioxide, nitrogen oxide.
Among them, Xingu heating plant "coal to gas" project officially started on May 16 this year, October 20, Sheung Shui, October 27 with the ignition conditions.
Riverside heating plant "coal to gas" on May 16 this year started, has completed the boiler and associated piping, heat pumps and ancillary equipment installation, ongoing electrical, control system debugging, October 22 has been Sheung Shui, October 29 have ignition conditions.
Summer Coal heating plant "coal gas" this year officially started on August 18, has completed commissioning of boiler facilities and associated piping, heat pumps and ancillary equipment installation, ongoing electrical, control systems, etc., on October 29 water, with firing conditions.
Natural water, even in seemingly pure tap water, contains a variety of dissolved salts, including calcium and magnesium salts. That is, the hardness material is the main source of scaling in steam boiler manufacturers in mumbais. Since scale is extremely harmful to steam boilers, removing hardness and preventing scale formation are the primary tasks of steam boiler water treatment, which can be achieved by chemical treatment outside the pot or dosing in the pot.
