Hot water boiler combustion chamber to prevent the return tube plate cracking measures what? Tubesheet before returning to the boiler combustion chamber is working three worst backhaul site, a long period of high and low temperature thermal stress, likely to cause thermal fatigue cracking tube end, where this configuration is the most prone to boiler problems.

Henan gas boiler after shutdown within 6h Why should how to do either normal cooling or emergency cooling during the first 6h gas boiler shutdown of Henan, are required to turn off all the smoke, wind and bezel door? Normal and emergency cooling Henan cooling gas boiler shutdown, in the first 6h after shutdown are identical, are required to turn off all the smoke, and air shutter door. When the difference is that the normal cooling, can be opened after shutdown 6h cited blower baffle natural ventilation, while emergency cooling, allowing 6h after shutdown and start the induced draft fan ventilation Sheung strengthening, accelerated cooling to turn on the water . The main factors restricting Henan shutdown cooling rate of gas-fired boiler, steam drum after the shutdown should not produce excessive thermal stress. Steam and water drum furnace heating and ignition boosting contrast, because external drum Henan Shutdown of the gas heat-retaining layer, the drum wall temperature drop is slower than the saturation temperature decrease rate of the steam oven and water, is an upper boiler water vapor and the lower wall of the cooling drum. Henan by gas boiler drum water wall heat transfer coefficient is large, the lower half of the drum wall temperature decreased rapidly, while the saturated steam into superheated steam at the heating drum half. Superheated steam only a very small thermal conductivity, but also because he and the steam temperature is higher than the temperature, density, and natural convection can not be saturated steam is smaller than the saturated vapor. Therefore, the heat transfer coefficient on the wall of the steam drum is small, the temperature of the upper half of the drum decreases slowly. On the drum, the lower half of bananas due to temperature difference occurs upwardly formed deformation thermal stress. When a large thermal stress is formed in the initial drum boiler shutdown Henan gas, high pressure steam drum further, the superposition of both the generated stress is large conversion. Therefore, the initial Henan gas boiler shutdown excessive thermal stress would endanger the safety of the drum. Since the size of the drum of a thermal stress, and the furnace depends on the velocity of the steam saturation temperature of water is lowered. Therefore, the most effective method of reducing thermal stress is slow drum speed drum pressure drop. Within the first 6h after shutdown, close all smoke. Wind baffle and door are the best and most simple way to prevent excessive pressure drop drum. After the gas boiler shutdown Henan 6h, due to the chimney and the furnace wall heat capacity remains the wind, cold air from the smoke, wind door, shutter and the tube through the wall, which do not leak into the furnace at a close absorb heat to become hot air It is discharged from the chimney. So, even close all the smoke, wind baffle door, drum pressure is still slowly decline. After the shutdown 6h, drum pressure has dropped to very low levels, even though the ventilation and induced draft fan started to strengthen Sheung Shui, turn on the water to accelerate cooling, thermal stress is also small drum, and the drum pressure is very low at this time due to its two translation superimposed stress were also smaller, has not pose a threat to the security of the drum.

For the oil industry, where steam boilers can be used in the oil industry is one of the key pillar industries. In general, large-scale oil exploration or refining industry, are inseparable from the large steam boiler thermal energy conversion or other use. The reason for selecting steam boilers for processing use, not only because of its high thermal energy, energy saving and environmental protection, but also to meet the demand for petroleum and petrochemical industries. Professional steam boiler in addition to the petrochemical industry can help stabilize the smooth processing use, but also to increase oil production and processing, to help companies generate huge economic benefits. Here follow the small series together to understand the reason the oil industry to use steam boilers. First, save processing costs due to the steam boiler industry in the course of processing also reduces power consumption saving and environmental protection in the use can reduce the cost of inputs, reduced costs, greater will be able to enhance the economic efficiency. Second, the steam pressure is stable, safe oil industry has been steam boiler will choose to use long-term process, but also because the steam boiler in use stability SAIC pressure is good, but also self-control in the boiler steam pressure value safe operation , security and stability and security equipment during operation. Therefore particularly suitable for processing large amount and long duration of the petroleum and petrochemical industries. Third, boiler energy-saving technology to highlight the conversion of oil boiler heat energy required to get it to be in the refining process, and the steam boiler with a unique energy-saving technology and variable frequency technology through automatic water supply operation, and will automatically be in a more stable situation adjusting the steam temperature and pressure, for continuous processes and therefore can be more energy efficient as compared to stable supply of petroleum in protecting normal processing can also be used while energy saving. The above is the reason for petroleum and petrochemical industries to use steam boilers, mainly because such conduct thermal energy conversion run steam boiler environmental stability and the principle of good energy-saving effect, and therefore the use of large petroleum and petrochemical industries fancy and reuse, sale good service steam boiler in addition to protect the safe and stable operation, but also in the long run save a lot of energy to the industry to enhance corporate cost-effectiveness.
