Recently, the Longhai carried out safety campaigns to the boiler, the campaigns start from the four directions, whether units in accordance with the boiler 'boiler safety practices "to use the correct boiler conducted a comprehensive inspection.
First, the unit register in a boiler boiler inspection. The use of units to crack down on unauthorized use of untested or failed the inspection of boilers.
Second, the units are equipped with a boiler if the security officer and fireman personnel. Focus on checking whether the use of units as required "special equipment operator assessment rules," the fireman with security personnel and staff to meet the requirements, and whether the person has made fireman fireman card.
Third, in the boiler unit will be the safety management system, emergency plans to check the system; and to convey the importance of this inspection in the boiler unit, raise awareness of security units.
Fourth, strengthen supervision of energy-efficient boilers, boiler and actively promote energy efficiency testing, at present, boiler energy efficiency testing has been completed a total of 112 units.
To date, the Longhai inspection operations were dispatched inspectors 209 passengers, checked boiler unit 136, check the boiler 168 units, eliminate safety hazards at 9, and urge the use of sealed units to enhance the energy efficiency of boilers 21 units.
And with the Commission by letter, and environmental protection departments to further promote the comprehensive upgrade of coal-fired boiler energy saving project, disable the coal-fired boiler 53 units, 34 units scrapped, replaced by raw material boiler fuel and natural gas fuel of a total of 40 units, is out of the city coal-fired boilers to make a positive response.
4 tons of steam boiler before firing what needs to be done to prepare a deal boiler conduct a comprehensive inspection before Sheung Shui, the water is softened before boiler water filling. 2, Sheung Shui should check whether there is water leakage valve, leaks should be immediately removed when found. 3, the check Sheung water temperature, pressure gauges, water level, no good production of inlet and outlet valves, smoke profile, said shutter is flexible, the flue gas channel is smooth duct, each cleaning doors are tight. 4, before firing coal with water 8-10%.
Process safety valve check valve gas steam boiler is one of the three safety accessories gas steam boiler, when the boiler pressure is too high, the pressure relief valve will automatically exhaust, gas steam boiler is the important safety equipment . The case of a new installation, overhaul, lack of consumer safety valve shutdown and restart more than three consecutive months, have had to re-check safety valve, safety valve to ensure accurate and reliable by the company safety officer, boiler technician, run operators, maintenance personnel together with the completion of the adjustment. Valve adjustment procedure is as follows: 1, the steam boiler when the gas vapor pressure close to the operating pressure of the safety valve, and retest check valve to the air motor exhaust, drainage accident flexibility and reliability of the electric valve, and the panel reinspection situ pressure gauge, the water level of accuracy, such as failure, not allowed to heat the school. 2, ready to call and check the quality of communication tools, a signal indicating whether the good. 3, adjust the safety valves, boiler pressure should be kept stable, pay attention to monitoring gas steam boiler drum level, and maintain normal. 4, steam boiler safety valve to adjust the pressure gauge in place of instructions shall prevail. If necessary using 0.4 or more for the accuracy of the gauge. 5, adjust the safety valve should be carried out only by descending. It should checksum gas steam boiler tuning high pressure safety valve, after the school seizure of the entire set of low pressure relief valve. 6, the following should be in the 0.3MPa, the movement preventing measures must do a good job of setting relatively low pressure steam boiler safety valve safety valve before adjusting. 7, by combustion, and exhaust steam adjust the degree of opening to the air slowly and smoothly up to the required setting pressure. 8, when the gas pressure steam boiler safety valve set pressure to rise if action is normal, then the action and reseating pressure values recorded. If action is not correct or not action should be immediately opened to the air exhaust valve, while the combustion boiler weakened, stop boost, and buck 0.3MPa or less, re-adjust the boiler technician as required by maintenance personnel, until the compliance date. (Lead or lag 0.05MPa action is normal). 9, after the completion valve to adjust gas steam boiler, boiler 0.3MPa or less down to the lifting device and can be installed and fastened to the protective cover, a braking measure required under check valve removal, then Articles 7, 8 verify until all required safety valve calibration check is completed. 10, the safety valve to adjust the gas boiler, check the results recorded in the "safety valve to adjust the recording Visa" within the participants should verify the signatures and Internet safety valve input to the corresponding data in the ledger. During operation gas steam boiler, not only to regularly check on the safety valve, at the same time, we must regularly monitor boiler inspection to ensure that the boiler fully meet the safety requirements!
When we use the boiler, it is unavoidable to have faults or abnormal phenomena, but in order not to affect the normal use, when the boiler appears problems should be dealt with in a timely manner, then in the face of all kinds of circumstances, how should we deal with it? Share with you some ways to handle exceptions. If only the boiler circulating pump abnormal, such as its current reduced, outlet pump pressure return to zero, which means that the pump is idling non-oil, may be caused by vaporization of oil. Therefore, first of all, Yang should take measures to identify the cause of vaporization; if the filter blockage causes the circulating pump to empty, the by-pass cleaning filter should be opened immediately; such as the new heat transfer fluid containing water or Water-decomposing gas is not excluded in the system, then the open valve should be opened immediately. If the circulating pump pressure is constant, the current increases and the flow rate decreases, the heat transfer fluid is metamorphic and the viscosity is increased, so it should be replaced or regenerated in time. If the gas containing water or decomposing is not excluded from the system due to the new heat conduction fluid, the gas should be discharged immediately by opening the valve. When the current of the circulating pump is lower than the normal value, it shows that the efficiency of the circulating pump is lower and the flow rate is decreased, which may be the fouling blockage of the heating pipeline, and the stainless steel chain should be cleaned. If the pressure difference between the front and back of the filter in the boiler increases and the pressure of the pump inlet drops, the filter may be blocked. The bypass should be opened and the filter should be turned on. Remove cleaning. In addition, the low outlet temperature of the liquid-phase heat carrier furnace and the lack of heat supply are mainly due to the problem of ash accumulation, so soot-blowing should be carried out in time. A more common problem with the boiler's grate is that it is stuck because it is broken or loose after the pin has fallen off; metal inclusions in the coal trap the grate; the grate is arched; and the tip of the slag stopper sinks to jam the grate. In view of this phenomenon, it is necessary to clean up the debris with the plate hand-down converter row, replace the broken furnace platoon and start again, if it is stuck again after the start-up, then check the causes after stopping the rotation and solve the problem in detail. At the same time, it is necessary to adjust the screws on both sides and tighten the grate, if it is still not correct. Often, you need to change the sprocket.
