What practices of industrial gas boiler industrial gas boilers need to comply with what practices need to comply with? Industrial gas boiler is a heavy power equipment, chemical industry, light industry and other industries that must be used, with him, in order to ensure the orderly conduct of production. To avoid the boiler due to unforeseen danger to life and property safety, boiler operator must pay attention to these guidelines in their daily work. Check valve instrument prior to use to check out the gas meter valves and main valve, in the pipe to be replaced to close it. When the door is opened, the situation should be noted that in the furnace, especially if gas leakage occurs. If you find a leak, you can not timely inspection and repair to ensure the safety before ignition. We can not have water inside the chimney flue, and should always be kept clear. Diesel is not allowed to place explosive and explosive products and other products around the boiler and set aside sufficient area of safety devices. Before starting the purge blower before ignition, and opening the air valve to each burner lips purged. Ignition, fire and other gases to pay attention, do not put the car before the horse, in order to avoid an explosion. If you experience a sudden accident power failure, the blower is stopped suddenly, need to immediately close the gas valve and the air valve all combustion mouth, and time to open the door when necessary to prevent accidents. Industrial gas boiler installed alarm once gas leakage phenomenon, alarms will sound immediately notify the operator of the boiler safe handling.
Chemical plant boiler cracks workaround solutions cracks which occur chemical plant boiler What? For use in chemical plant boilers in the process, if it is cracked, then, it must be to crack for the prevention and treatment of the same treatment. First, in the production process, for the boiler should be able to strictly control the production and inspection related. In the process of the boiler, but also from time to time to regularly tested for pot boiler. Crack is found timely manner. Prevent the boiler accident. (A) of the Boiler and Pressure Vessel pressure pipelines made strictly deal with all aspects of First off, generating boilers and raw material quality equipment belonging to manipulate. Chance of handling various aspects of the production, each process strict inspection procedures, the data should crack formation of the information generated boiler continuous improvement and improve production skills, the development of production standard, clear production requirements to ensure that the operation of the production process specifications, useful to minimize . Second, carefully review every aspect of the production of boilers and pressure vessels pressure pipeline made to ensure that staff operate in accordance with the production specification, presented to prevent mistakes in the production process. Finally, the use of the device and process of the boiler supervision handle this process the most important thing is to improve the level of human action. (B) to strengthen inspection efforts boiler equipment Boiler and Pressure Vessel pressure pipelines to carry out inspection in accordance with the norms When completed, put into use before the device you want to view again, daily life and work to do specific records, to understand changes in boiler and pressure vessel pressure pipelines , from the source to prevent the formation of cracks problem of security risks. Also, never slackening the inspection work of the aging boiler equipment, increase the frequency of inspection, inspection scale expansion. In addition, to establish and improve the relevant inspection criteria for checking workers' behavior constraints. Economic harm Boiler and Pressure Vessel pressure pipelines as a high-temperature equipment, process equipment operation if presented unexpected problems, will probably lead to explosions, thus forming a certain level of damage to people's lives and industrial city, not even lead to the rescue . Thus, the pressure in the boiler and pressure vessel inspection work is necessary to apply well to crack the problem presented to be focused on equipment and handling, inspection of crack problems in boiler and pressure vessel pressure pipes, the analysis should form the crack in the crack of discrimination nature, category and influencing factors, according to relevant skills should crack features, the timely adoption of useful scientific and reasonable way to deal with, deal with crack problem for the supply of equipment to ensure safe operation.
For the continuous improvement of the province's environmental air quality, enhance people's happiness index, Henan Province Government Office issued the "2019 campaign of air pollution control implementation plan." Details are as follows.
1, to carry out special treatment industrial furnaces
Based on the melting furnace, the melting furnace, sintering machine (furnace), roasting furnace, a heating furnace, heat treatment furnace, a drying furnace (kiln), coke oven gas furnace 9 categories, to carry out an intensive investigation, the establishment of industrial furnaces Details inventory management, enhance the implementation of classification regulation. Not included in the investigation of industrial furnaces list, all included in the autumn and winter peak load shifting discontinued inventory.
2, to carry out clean alternative
Of coal, petroleum coke, residual oil, heavy oil as the fuel of a heating furnace, heat treatment furnace, a drying furnace (kiln), and actively promote the use of natural gas, electricity and other clean energy and the use of plant waste heat, heating power plant and the like instead.
3, to carry out comprehensive improvement of industrial boilers
Before the end of October 2019, in addition to undertaking tasks and will not have the alternative livelihood conditions, the province's basic complete 35 steam tons / hour boiler clean energy transformation or removal of coal-fired. Transformation methods include the removal, an alternative central heating, gas coal, coal to electricity, use geothermal, wind, solar, biomass with a bag filter. Chaigai on schedule to complete the coal-fired boilers, based on 40,000 yuan / tons of steam prize money up. Forbidden to use has been shut down and eliminate waste coal-fired boilers to cash rewards and subsidies.
4, strengthen upgrading gas-fired boiler
Before the end of October 2019, the provincial municipality and county (city) district built more than 4 tons of steam and low nitrogen gas boiler complete transformation after transformation, soot, sulfur dioxide, nitrogen oxide emissions are not higher than the concentration of 5,10,50 mg / cubic meter.
5, strengthen upgrading oil-fired boiler
Before the end of October 2019, the provincial municipality and county (city) district built more than 4 tons of steam and fuel (including alcohol-based fuel) boiler low nitrogen complete transformation after transformation, soot, sulfur dioxide, nitrogen oxides emission concentration is not high in 10,20,80 mg / cubic meter.
6, vigorously promote urban central heating
Full use of existing resources and central heating facilities, the existing large-scale heat sources and central heating pipe network in the area, in-depth investigation heating demand, and promote the rich heating capacity extends to reasonable radius and root out the potential heating, heating reduce blind spots. Before the end of October 2019, Zhengzhou, Anyang, Jiaozuo, Puyang City, built-up area of central heating penetration reached more than 90 percent, Xinxiang City, central heating penetration reached more than 85%; Luoyang, Xuchang, Jiyuan City, central heating penetration reached 3 more than 80%; Sanmenxia central heating penetration 75% or more; unsealing, Pingdingshan, Hebi, 4 Zhumadian City, central heating rate of 70%; Luohe, Shangqiu, Nanyang 3 City central heating penetration reached 60% .
After the scale appears, the thermal conductivity is only 0.5% of the metal. After the boiler scale appears, if the heat efficiency of the scale is reached, the temperature of the heating surface inside the boiler can only be increased. For example, when the wall temperature is 250 °C, When the scale is 1mm, if the same thermal effect is to be achieved, the wall temperature will increase to 650 ° C. At this time, the heat absorption rate is extremely low, the energy consumption is increased, and the fuel cost is doubled.
