boiler for paper processing industry
Personnel to operate the boiler for paper processing industry operation is necessary for the correct installation and use precautions safety valve.
1, rated evaporation> 0.5 ton steam / hr gas boiler, at least two safety valves installed; Rated evaporation ≤0.5 steam tons / hr gas boiler, mounted on at least a safety valve. The separable exit of the economizer, steam superheater outlet of the safety valve must be installed.
2, the safety valve should be mounted vertically in the boiler drum, at the top of the header. Between the valve and the drum or header, not equipped with access to the steam outlet pipe and the valve.
3, the lever-type safety valve should prevent movement of the self-apparatus and the weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly.
4, the rated steam pressure ≤3.82MPa boiler safety valve throat diameter of not <25mm; the rated steam pressure> 3.82MPa boiler safety valve throat diameter of not <20mm.
5, the safety valve and boiler tubes, which cross-sectional area not less than the cross-sectional area of the valve inlet. If several valves installed together with a short tube directly connected to the drum, short tube passage area not less than 1.25 times the area of all the exhaust valve.
6, the safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. Safety valve exhaust pipe at the bottom should be fitted to the safe location of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.
The continuous advancement of technology is the core competitiveness of ZG boiler for paper processing industry. For a long time, ZG boiler has established cooperation relationship with industry, research and research institutes with more than 10 well-known scientific research institutions such as Chinese Academy of Sciences, Tsinghua University, Xi'an Jiaotong University and Huazhong University of Science and Technology. The investment in construction is huge. ZG boiler has obtained more than 130 national patents, and has continuously introduced advanced technology. He has participated in many major scientific research projects and has won many certificate honors. ZG boiler attaches great importance to environmental protection and energy conservation, and has invested heavily in it. In 2016, ZG boiler successfully signed Zheng Luoxin's national self-made zone and started the construction project of Industry 4.0 Super Smart Factory. It will continue to inject smart vitality into ZG boiler, so that ZG boiler 's cutting-edge technology and product research and development are always in the forefront of the industry.
February 20, 2019, the Beijing Municipal Government issued the "Beijing's pollution prevention campaign of 2019 Action Plan" (hereinafter referred to as the "Action Plan"). "Action Plan" clearly 2019 development goals: the first is the city PM2.5年均浓度, three-year moving average concentration strive to continue to decline.
Since 2018 autumn and winter, fog and haze in control efforts continue to increase. Beijing, Tianjin Fenwei Plain, the Yangtze River Delta region of the focus of supervision and maintain a high pressure situation, provinces and cities have also introduced Blue Sky Battle plan, air pollution control sector welcome the opportunity. And because the 2018 autumn and winter abolition of green "one size fits all", so that pollution from the administrative means to switch to environmentally friendly means to speed up environmental protection business orders release.
"Winning Blue Sky Battle three-year action plan" called for increased efforts to eliminate small coal-fired boilers, the county level and above urban area basically eliminated 10 tons of steam per hour and coal-fired boilers, in principle, to the new 35 per hour tons of steam coal-fired boilers. We believe that, under constant fog and haze, the small boiler phase-out process will accelerate. Research believes that by 2021 the transformation of coal-fired central heating investment 88.6 billion yuan, annual operating income of 240 billion yuan, the central heating market will also speed up the release with the environmental supervision.
Professionals expect non-electric air control about 192.2 billion market space, ultra-low emission thermal power market reform space of about 65.7 billion yuan, the whole vast air pollution control requirements.
In addition, the high diesel vehicle emissions, is also one of the main source of haze pollution. Considering the number of ministries had jointly issued by the Ministry of Ecology and environment "diesel truck pollution control tough fight Action Plan" diesel vehicles, boats become the focus of the next step of action to win the Battle of the blue sky.
Many customers prior to purchase gas steam boiler for paper processing industry, does not know how to express some of the basic parameters of the boiler, each alphanumeric represents what it means. Henan Fang Xiao Bian today's fast boiler for everyone to explain about one ton of gas boiler steam parameters:
1, evaporation: long-term continuous operation of the boiler in the premise of ensuring safety, the number of generated steam per hour, called the evaporation of the boiler, also known as the "output" or "capacity" common units "t / h "(t / h).
