horizontal hand steam boiler parts and functions

In response to the state-assigned air quality improvement objectives and environmental supervision central feedback coal-fired boilers environmental pollution rectification program, Kang County, Gansu Province based on "government-led, relying on real responsibility, Take Measures to proceed with" principle, accelerate the burning of remediation work out of the coal boiler, and to develop the following measures, at present, reconstruction activities are being actively promoted.

A: a comprehensive investigation, the establishment of accounting. For urban areas, towns, Kudo industrial parks all coal-fired boilers to conduct a comprehensive diagnostic investigation, a total of investigation and the use of the boiler 31 enterprises, a total of 38 boilers, electric boilers and removal of fuel two boilers, coal-fired boilers county a total of 36, including two sets of 20 tons of steam boilers, coal-fired boiler pressure 4. In the diagnostic process, the situation boiler location, type, number of units, the tonnage, use, carefully verify the age and so on, and sort out the summary, so that a boiler does not leak, the device information is not a shortage.

Two: to strengthen publicity, and create atmosphere. Through new media, focus on advocacy, government circulars issued, will be held to promote the government leaders in charge of on-site investigation led mobilization and other forms of media offensive formation, multi-level multi-angle carry out various forms of publicity and education remediation phase out coal-fired boilers, each guide society personnel support and participate actively promote the use of coal-fired boiler units understand the situation, to speed up the phase-out of coal-fired boiler renovation.

Three: supervision of interviews, results-oriented. Person in charge of the county Bureau of Quality Supervision led, in-depth coal-fired boiler unit, for the slowness, lack of knowledge, waiting to see the business units and enlighten them with reason, and emotionally moving. With the responsible persons of the two job interviews lag to not be one of them out of the situation Reconstruction of boiler in accordance with national policy requirements, on-site recovery boiler registration certificate and ordered deadline to be removed or modified.

Kang mentioned standard by the transformation, step out, closed down closed down, to gas and electricity from coal to supervise a number of measures to actively promote the elimination of remediation coal-fired boilers. Currently the county out of 29 coal-fired boiler units, of which 15 units destructive demolition, stop burning close 12 stations, two mentioned standard transformation. The remaining seven out of focus on remediation plan included in this year, the county continues to promote this work, and to call on the unit enthusiastic, standards do not fall, the team leave, determined to complete the end of October this year, the county and below 10 tons of steam coal-fired boiler work all clear.

Of course, but also a concrete analysis of specific situations. We also have a variety of products for small boiler heating area, such as commercial, condensation series.

Damage of load-bearing parts of Boiler and its Prevention

The basic requirements of safety and reliability of boiler structure are as follows: (1) all heating surfaces of boiler should be cooled reliably; (2) the thermal expansion of each part of boiler should meet the requirements after the boiler is heated, and the basic requirements of boiler structure are: 1) the heating surface of boiler should be cooled reliably; (3) the compression components of boiler have sufficient strength and compactness; (4) the boiler furnace and flue have certain anti-explosion ability; (5) the load-bearing parts of boiler should have sufficient strength, stiffness and stability, and can meet the seismic requirements of the area in which they are located; Boiler structure should be convenient for installation, maintenance and operation. In the past, the failure of boiler parts was analyzed, and more attention was paid to overheating, corrosion, wear and welding quality. Once the steam pipe, water pipe and pipe can't bear the internal pressure under the action of steam and water pressure, the tube boiler will burst and leak. However, since the suspended boiler structure has been adopted, because of the boiler heating surface, steam-water header, pipe, flue coal pipeline all through the hanger, beam, truss, by the steel column load-bearing; and with the expansion center as the zero point, down, and around the expansion. Once the load-bearing system fails and the parts are attached, the geometric shape of the components will change, which can also lead to the failure of the boiler parts. The theoretical calculation shows that a slender heat pipe can bear high internal pressure, but it cannot bear normal axial pressure, let alone bear. Due to the lateral bending force, we must pay attention to the deformation failure. Looking at the damage accident of boiler load-bearing parts, it is not difficult to find some characteristics of the damage accidents of supporting hangers:

Under the bad condition of the pipe network, the water supply rate of the system will rise, and the increase of the water supply will inevitably lead to the increase of the scale quantity, and the harm to the boiler will increase with the increase of the water supply rate of the system.
