what are important consideration in starting boiler project
Boiler not cleaned What are the dangers what are important consideration in starting boiler project daily to do the cleaning work, the scale should be cleaned, so as to avoid unnecessary losses, which harm the following look at the boiler scale: 1, causing the metal heating surface of boiler overheating, damage to the boiler, shorten life. Boiler heating surface green scale, cooling the metal wall surface is affected, resulting in increased wall temperature, the mechanical strength of the metal material is reduced, resulting in heating surface deformation, bulge, burst pipes and the like, or even a serious explosion. Damage to the boiler, affecting life. 2, to reduce the evaporation boiler, reducing the thermal efficiency of the boiler, waste of fuel. The presence of boiler scale is equivalent to an additional layer of resistance heating surface, because the scale is lower than the thermal conductivity of steel is large, hindering heat transfer, the heat released by combustion of fuel can not be effectively transferred to the water, water vapor can not be measured heat , with the exhaust gas side of heat is lost, and therefore to reduce the boiler output, fuel waste. According to statistics, the junction of a millimeter scale, about 2 to 3% waste fuel. 3, disruption of normal boiler water circulation, forced shutdown maintenance, increase maintenance costs. After water boiler fouling, reduced flow cross-section of the inner tube, the flow of power to increase the water cycle, even when serious completely blocked. Disrupted and boiler water circulation pipe burn, forced shutdown for maintenance. Waste of human and material resources, resulting in losses. In short scale great harm to the boiler, the boiler can not be safe and economic operation. Explosion-proof doors too heavy or inadequate pressure relief area; Exhaust Gas Temperature unreasonable. Caused by poor management of the boiler running water or boiler filled with water; poor management of water quality caused by boiler scaling; oxygen poor metal heating surface corrosion; sewage is not timely boiler water alkalinity is too high; adjust the boiler is not timely adverse atomization, incomplete combustion, flame instability or skewed; the fault itself or combustion burner system failure caused by boiler flameout. In summary, boilers and process design supporting improper installation, operation mismanagement can cause accidents occurred boiler, enterprises and workers to bring the loss of life and property. As long as we understand and master the hidden laws of boiler accident, strict boiler design, boiler installation, boiler management, and constantly improve and perfect the boiler management method, you can while avoiding disadvantages, to avoid boiler accident.
How to determine whether the positive pressure hot water what are important consideration in starting boiler project manufacturer of professional pressure hot water boiler formal professional manufacturers give the public supply professional, targeted one-design, supply and so give a more professional public pressure in addition to heat the overall water boiler system policy, can guarantee exact top standards within the industry, may have the highest price, we can make any other purchase money there is no pressure for functionality and safety with the terms, then, can get the most professional eligibility criteria.
Whether specific differences between different types of alarms and gas-fired what are important consideration in starting boiler projects need a gas boiler, which is a common and popular types of boilers, but also the product website, it is necessary to be familiar with and understand, because the only way to correct and reasonable use of this kinds of boilers, and make good use of the product effect, so that full use instead of wasted product. 1.6 tons of gas boiler, whether there are requirements on the consumption of natural gas? 6 tons of gas boiler, which is used to generate steam, if so, which generates between gas consumption and the tonnage of 1 ton steam boiler, from a professional point of view there is no relationship, is to look at the main boiler feedwater pressure and temperature, and, that there is a corresponding formula, depending on the furnace and different work efficiency, it is going to get a different result, therefore, to have a correct understanding at this point, can not go wrong. 2. purchase gas boilers, mainly to see what? It is necessary to install an alarm device? Buy gas boiler, which is an important task, and is an important aspect of this kind of boiler, it can not be ignored and careless treatment, because if contempt and careless treatment, then there will be the wrong choice, then, affect the product normal use, and resulting in product wastage and economic losses. Therefore, these conclusions will have, and the above requirements must be strictly enforced. In which the selection is to consider whether a discharge requirements, the type of gas used, the thermal efficiency of working fluid required, as well as hot water or steam to. The gas boiler, if the standard reference GB50041 "boiler design" is the need to install the alarm device, in particular, the concentration of combustible gas to install the alarm device, but also a boiler room of its specific requirements. And whether the type 3.SZS WNS-type gas boilers are different? From a professional point of view, the WNS and SZS type type gas boiler gas boiler Both models are compared, there is a significant difference, because SZS type gas boiler is a double boiler barrel vertical water-tube boilers, WNS type boiler for gas horizontal three-pass boiler tube fireworks. Further, SZS type gas boiler is mainly less than 10 tons of gas boiler, gas-fired boiler is mainly WNS type of gas boiler 10 tons, are in tonnage, structure and properties are significantly different.
Battle for winning Blue Sky, effectively improve the region's ambient air quality; Ningxia Hui Autonomous Region developed and published a "region-owned coal-fired thermal power units reconstruction plan for the ultra-low emission" (hereinafter referred to as the "Program"). "Plan" put forward plans before the end of 2020, nine companies owned coal-fired power plant 25 thermal power units for ultra low emissions transformation.
By the end of 2020, all the region's coal-fired thermal power units with self-transformation conditions by upgrading desulfurization, denitrification and dust removal facilities, the concentration of pollutants in atmospheric emissions all meet ultra-low emission requirements; long-discontinued businesses in the pre-production must be restored owned ultra-low emission coal-fired units to complete the transformation; gradually shutting down key areas do not have the conditions for the transformation of high-polluting coal-fired captive power plants; emission concentration of air pollutants new coal-fired gas turbine generator set to achieve set emission limits; the country City and Ningdong Management Committee in conjunction with the region's environmental quality improvement requirements, and actively promote the transformation of ultra-low emissions to arrange more than 65 tons of steam per hour of coal-fired boilers.
After the completion of the transformation project, owned coal-fired power plants should entrust a third party consultant for technical performance, environmental effects, equipment stability, comprehensive assessment, evaluation findings and issue.
In order to encourage enterprises to increase efforts to transform ultra-low emissions of pollutant emission concentrations below the pollutant discharge limits set by the state or place more than 50 percent, halved implement environmental tax policy. At the same time, we encourage financial institutions to give preferential credit support, to support eligible owned coal-fired thermal power enterprises to issue corporate bonds direct financing, to raise funds for ultra-low emissions and energy saving. According to the regional administration of appropriate incentive funding arrangements, to ultra-low emission reduction projects included renovation crew around them, give appropriate incentives based on emission reductions, combined with local conditions to increase financial support.
"Plan" requires all localities and departments should strengthen daily supervision and inspection of law enforcement to prevent corporate fraud, is not scheduled to complete the transformation of the self-ultra-low emission thermal power phase-out, discharge permit authorities to promptly subtract the emissions permit, for non-compliance business severely dealt with according to the law, to the public.
