Recently, the Guangzhou City issued an action "Guangzhou 2018 annual work plan for comprehensive prevention and control of air pollution," the bureau of law enforcement to monitor the detachment on August 28 = 29 organizations launched a special enforcement action against a biomass boiler.
The special enforcement action by the municipal and district levels of environmental protection departments jointly launched, deployed Yuexiu, Tianhe, Haizhu, Huangpu, Conghua five district environmental protection law enforcement backbone, with the Guangzhou City Environmental Protection law enforcement inspection detachment composed of 18 cross-law enforcement group, to increase the city all registration to carry out quality checks of 125 biomass boilers in the book, focus on examination of Guangzhou boiler emissions monitoring system in Zengcheng District registered the existence of complex biomass boilers coal or other high-polluting fuels, whether there are special furnace and supporting bag dust removal facilities, whether the normal operation of the boiler control facilities, whether discharge standards as required entry and update Guangzhou boiler emission monitoring system and other issues.
After verification, the registration system by the city list in the boiler has been disabled (off or relocated) boiler station 43, not included in the other eight found regulatory list table 133 actually inspected. Among them, 28 units involving suspected violations accounted for in the boiler problem with the boiler (90 units) ratio of 31%, the problem of coal-fired boilers in complex 2, the resurgence of firewood, 11, allegedly did not apply for environmental protection procedures, waste gas treatment is not installed facility or facilities are not the normal use and other illegal activities 15. For complex high-polluting coal and wood fuel boiler according to law-site seizure and transfer penalties and territorial environmental protection departments to follow up treatment in accordance with the relevant provisions of Article 107 of the "People's Republic of China Air Pollution Prevention Law." The rest were arrested for illegal transfer of territorial environmental protection departments for investigation.
How to choose oil-fired boiler with strong integration of countries on the environment, coal-fired boilers have been gradually phased out, replaced by a new generation of oil-fired boiler, we said what issues should be considered when selecting it do? Today small FYI for everyone finishing five points. 1 From the conditions of use. If the system is used in a liquid phase, generally should be selected higher than the boiling temperature of the thermal oil, because the higher boiling point, low vapor pressure which the motion, easy to use; if it is used under vapor phase conditions, should be selected in the appropriate at use temperature, then the vapor pressure in the range of 0.098 ~ 0.294MPa the HTF (1 ~ 3kgf / cm), as a low melting biphenyl diphenyl ether mixture plus HTF. 2 from the viewpoint of temperature. Select the appropriate temperature according to the HTF. If the temperature at 350 ~ 400 ℃, biphenyl and diphenyl ether should be used in a low-melting mixed conducting oil; temperature at 300 ~ 350 ℃ should be considered when selecting alkylbenzene type, dibenzyltoluene or hydrogenated terphenyl type HTF; temperature at 250 ~ 300 ℃, can consider selecting Kenai alkoxy, benzyl toluene, and benzene conducting oil; 250 deg.] C or less if used, is selected relatively low price of mineral conducting oil. 3 from the viewpoint of equipment and system conditions. As used in the long-term continuous operation of the system, must use a high thermal stability HTF; when used in a batch-type operation system, the thermal stability requirements can be relaxed some equipment during the outage, it may be considered by warming maintaining respective temperatures; if used in the device system relating to food processing, consider use non-toxic or low toxicity and high safety of products, such as silicone, fluorine and the like; heating, cooling processes use the same thermally oil, due to the selected temperature range broader HTF. 4 from the use of regional conditions and requirements to consider. If used in cold northern areas, should choose low-temperature fluidity and good thermal oil, in order to start the device; Jin Yong in place strict requirements on dangerous goods, should be considered the choice of security is good, non-flammable fluorocarbon products . 5 from the standpoint of economic efficiency. Both Wumart but also cheap and affordable to, to reduce costs. Above is the sort of small series for everyone all the time in the selection of oil-fired boilers should refer to the points I hope for your help.
By the economizer boiler body + + + condenser condensing gas boiler auxiliary boiler composition; auxiliary equipment mainly includes: a control cabinet, a burner, supply pump, condensing circulating pump, an economizer, sub-cylinder, chimneys and the like.
The well-known and high-quality gas and hot water boiler enterprises of the old users usually have good reputation. Users who have used the equipment of the manufacturer share their own experience, and users can learn from the side how the boiler quality of the manufacturer is. Whether the boiler automation degree is high, whether the manufacturer service is sweet, and so on.
