After a long period of operation, the gas-fired hansung hasing drier boiler indus co korea inevitably has the problem of scale and corrosion. The main reason for the formation of the scale in the boiler is that the water is supplied with a hardness component, and after continuous evaporation and concentration at high temperature and high pressure, A series of physical and chemical reactions take place in the furnace, forming a hard, dense scale on the heated surface, which leads to the decrease of heat transfer effect and the corrosion factor under the scale, which will lead to the decrease of heat absorption in the boiler water wall furnace and the increase of boiler outlet temperature. Increase the boiler loss. At the same time, after scaling in the water wall, the heat transfer effect is reduced, which may lead to the increase of the wall temperature in the water wall and the explosion of the tube in the water wall, which affects the safe operation of the boiler. Scale is the first harmful factor of boiler, and the main cause of boiler accident. Its harmfulness is mainly manifested in the waste of a large amount of fuel: because the thermal conductivity of scale is only a fraction of that of steel, the heat transfer will be blocked after scaling on the heated surface. In order to maintain a certain output of the boiler, it is necessary to raise the temperature on the side of the fire so as to cause the heat loss caused by outward radiation and exhaust smoke. Gas-fired boiler cleaning steps: one step: scale removal cleaning, in proportion to the circulating water in the cleaning tank added a well-equipped scale cleaning detergent, boiler cleaning and scale removal, according to the amount of scale to determine the cleaning cycle time and the number of chemicals, Make sure all the dirt is washed down. Then proceed to the next cleaning procedure. Step 2: clean water, after connecting the cleaning equipment and boiler, clean with clean water circulation for 10 minutes, check the state of the system, whether there is leakage, at the same time rinse away the floating rust. The third step: stripping anticorrosion cleaning, adding surface stripping agent and slow release agent in the circulating water of cleaning tank according to proportion, circulating cleaning for 20 minutes, separating the scale and cleaning components, and at the same time carrying on the anticorrosion treatment to the surface of the object without scaling. Prevent the cleaning agent from corroding the cleaning parts when cleaning. Step 4: passivation coating treatment, adding passivation coating agent, passivation coating treatment of boiler cleaning system Prevent corrosion of pipes and components and new rust formation.

Step 1 hansung hasing drier boiler indus co korea pressure test, pressure test should be carried out when the ambient temperature is higher than 5 ℃, antifreeze measures must be below 5 ℃, water pressure test should be maintained above the dew point of the ambient temperature to prevent boiler surface condensation, water seepage and the occurrence of the situation will not tight confusion, difficulty increases inspection; but it should not cause high temperature to prevent vaporization (so difficult to find the leak) and excessive temperature stress, usually 20 ℃ ~ 70 ℃. 2, after the water is full, pressure is gradually increased to 0.4MPa, namely a tight check, if necessary, be tightened once the flange, and hand Manhole cover bolt hole. 3, water pressure test, pressure should slow down, when the pressure rises to the pressure of work, should be suspended boost, check for leaks or anomalies, and then boosted to the test pressure for 20 minutes, if the pressure It did not decline, that is, down to the working pressure checked. 4, no leakage was found records should cook, in order to reduce the time to repair the atmospheric pressure. Pressure test meet the following cases, i.e., that qualified: 1, and no water mist on the walls of the pressure receiving element and weld metal; 2, after the pressure test, no residual deformation visible; 3, economizer tubes, and The interface is not leaking.

4. Color pattern plate packaging, mirror finished stainless steel, or brushed stainless steel, elegant appearance

5. ASME standards oil fired boiler is more safe and reliable

Recently, the Weifang Municipal Quality Supervision Bureau investigation work for power plant hansung hasing drier boiler indus co koreas, boiler pipes mainly the situation, avoid boiler due to pipeline damage caused by explosion or other accident, serious economic losses and social impacts.

Quality Supervision Bureau adhere to problem-oriented, carefully study and strictly enforce the AQSIQ and the Provincial Quality Supervision Bureau of the requirements for the range of power plant boiler pipeline design, manufacture, installation, inspection, management and regular inspection of the use of accurate knowledge boiler safety awareness the importance of strengthening the red line awareness, risk awareness and responsibility to play, continue to maintain high pressure, strengthen safety supervision work of the power plant boiler tubes.

Bureau of Quality Supervision focus on checking whether the boiler tubes carry out regular inspections in the construction of power plant boiler accessories combination whether to implement supervisory inspection of manufacturing, installation work unit level meets standard requirements, flow meter housing if there is a security risk, whether the use of units developed power plant boiler tubes emergency plans and emergency rescue exercises, in a timely manner to improve the problems found.

To date, Weifang City inspectors were deployed 257 times, check the power station boiler unit 58, checking in with a number of boiler 193 units, eliminate safety hazards 78.
