Gas furnace gas steam mass identification of the method for determining the gas quality of a gas steam oven, it must have a manufacturing license manufacturer, the manufacturer must have a manufacturing license, the users must purchase gas stainless steel float fired steam boiler with production of qualified manufacturers product. See calculation but also the strength and structural design aspects of the gas furnace gas and steam, the furnace is all vapor pressure, and steam oven gas liquid gas into the furnace pressure injection and suction two unpressurized species. Heat Transfer Fluid pressure element whether or not the furnace, it should be calculated according to the current standard boiler intensity calculated geotextile design pressure applied to the working pressure 0.3MPa, and not less than 0.59MPa. Secondly, it is necessary for the steam furnace gas pressure test gas, which when assembled in the manufacturing unit and the unit is mounted in use, a pressure test were performed after repair. Electrically heated gas steam boiler, its pressure test into pressure test, hydraulic pressure test and tightness test. Whether gas furnace electric heating gas or liquid steam boiler furnace, the manufacturing units have to conduct hydrostatic testing, hydraulic test only in the use of the unit, and should not pressure test. For electrically heated gas steam boiler furnace gas, but also in the manufacture of air tightness test unit and used to check the seal of the non-welded joints. Test Method airtight electrically heated gas steam boiler and the requirements of the relevant provisions of the pressure vessel is. For electric heating liquid gas steam boiler furnace, not required tightness test. At the same time, more stringent control of electric welding quality heating gas steam boiler, organic heat carrier due to the electric heating gas steam boiler easy to leakage, flammable, so the electric welding organic heat carrier furnace gas heating boiler steam requirements compared to a medium boiler water is high, the quality of welding should be strictly controlled electrically heated gas steam boiler.

Industrial boiler market share rise, to the current trend of energy-saving industry, industrial boilers are mainly used in metallurgy, chemicals, coke, cement, paper, shipbuilding and other industries, mainly through heating boiler, steam production unit each to provide the required or hot water. Different transformation and power industry, industrial boilers since often small cell capacity, installed at the rear end of expensive desulphurization and denitrification apparatus is very uneconomical, so the transformation of coal will be the main alternative route, the coal gas, biomass fuels, cleaning three coal technology route, clean coal will assume the main task. By the end of 2011, the total industrial boilers reach 58.5-60 million units, of which the boiler, the capacity accounted for more than 80% of coal-fired boilers, boiler capacity is less than the number of 35 tons / hour of 96% of the total, while 10 accounting tons / hour up to 80%. Meanwhile, the average thermal efficiency of industrial boilers only 60%, 20-25% lower than in other countries. The country's industrial kilns more than 160,000, concentrated in building materials, metallurgy, chemicals and ceramics and other industries, the annual coal consumption of 300 million tons. The average heating furnace thermal efficiency of only 40%, 10-30% lower than in other countries. A wide range of large industrial boilers in China, the average capacity of small and dominated by coal. Although China's coal-fired industrial boiler design productivity gap compared with foreign small, but the actual operating efficiency of only 65%, 10% -15% lower than the advanced level. Industrial boilers with maximum downstream chemical materials and chemical products manufacturing market size, non-ferrous metal smelting and rolling processing industry, petrochemical industry market size is large, in addition, the market size paper and shipbuilding industries is relatively small, moderate growth in the cement manufacturing industry . Overall, the future of Chinese boiler market demand is still the main metallurgy, chemical and petrochemical three coking industry, and paper, cement and other industries demand is relatively weak, shipbuilding recession has not slowed. Industrial boilers, especially coal-fired industrial boilers for energy saving is important for achieving the overall goal of energy conservation.

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.

Free supervisory inspection principles and characteristics of small stainless steel float fired steam boiler as the country increasingly stringent security checks on special equipment, many users are in for acceptance steam boiler to worry about, then there a boiler inspection and acceptance does not require it? The answer is yes, this is the free acceptance boiler steam boiler, supervisory inspector now free to receive more and more small steam boiler users of all ages, so check the small steam boiler-free monitoring What are the principles and characteristics of it? Then we explain for everyone. First small steam boiler uses a very broad, such as industry, food processing, school canteens, washing rooms, hospital disinfection, hotels, district heating, etc., there are coal, oil and gas heating, where coal-fired steam boilers currently in my company alone this one domestic production, steam boilers do not build a separate boiler room, small size, light weight, easy to move, can be placed in the basement, roof, etc., the Boilermakers do not need to operate licensed fireman, replacing every year dealing with government departments, small steam boiler-free acceptance than conventional boiler safety, this boiler will not explode, it is composed of a coil, burning very fast start, whether it is coal, oil or gas to ensure 3 minutes to a steam, does not require inspection and monitoring of the subject. Overpressure, over-temperature combustion, water and other multiple protection, ultra-safe, non-explosive, can greatly reduce the burden on the user.
