4000kg steam water tube boiler

(1) safety valve

Safety valve ensures that the boiler pressure within the specified range, if exceeded boiler steam pressure, the valve will alarm to alert the operator to take appropriate measures; the other role is to the boiler pressure and blood pressure, to ensure the normal operation of the boiler.

In response to the state-assigned air quality improvement objectives and environmental supervision central feedback coal-fired 4000kg steam water tube 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.

For the scale silicates, more pickling effect.

But the party fast hot water boiler experts also concluded a more important note: general dirt simple suggestion pickling, so lower costs. Mechanical descaling is generally less than 1 mm scale clean-up, if the amount of scale thickness to be selected in the above pickling.

It may also be that the expansion tank is not consistent with the constant pressure of the 4000kg steam water tube boiler. The height is less than 15 meters, but the constant pressure of the boiler is 2.5 kg / cm ~ 2. In order to maintain the 2.5kg/cm2 working pressure index, the boiler workers often carry on the replenishment water, which spills into the trench unambiguously, that is to say, the water is consumed as well as the coal is consumed. Shut down the furnace and do not maintain it. After the heating period, the boiler was shut down, temporary workers were dismissed, some boilers were full of softened water, some boilers were exposed to the atmosphere, lack of necessary maintenance.
