Advantages and disadvantages of gas-fired boiler gas boiler is a clean burning natural gas for industrial boiler energy section of industrial production output of hot water and steam. After the recent years, increasing environmental pressures and an increasingly serious energy crisis, the government has introduced a series of laws and regulations on the promotion of energy conservation and emission reduction, to encourage new energy promotion, etc., should be transported from the gas boiler, coal-fired boiler broke thriving situation. Compared with conventional oil-fired boilers, coal-fired boiler, gas boiler has incomparable advantages, mainly in the following aspects: 1, and the consumption gas boiler artificial hydroelectric low cost; 2, or energy of the flue gas boiler condensate promotion of technology, it greatly enhance the thermal efficiency further, when the boiler flue gas temperature is reduced to 80 degrees or less, up to 95% efficiency; 3, clean environment, boilers small footprint, low failure rate, can be significantly improved use the unit on-site environment, adequate supply and lower prices, environmental requirements higher cost areas of comparative advantage of obvious; 4, due to the use of this type of boiler is clean energy, it will not produce combustion in the furnace at the time of soot and dust, so the operating life than other types of boiler long. However, due to the environmental advantages of natural gas and energy in a growing proportion of supply and demand and Jiazhiguilv bound to make the country in the future and gradually it with other primary energy prices linked to float, its long-term price trend will gradually open. In addition natural gas shortages in some areas or seasonal shortages also affect the reasons for its further promotion. On the whole, the use of gas-fired boiler more good than harm, to promote the use of gas-fired boiler is still the trend. Zheng pot shares as a professional supplier of boilers, gas-fired boiler in terms of a series of development and exploration, successfully developed the first low nitrogen gas boiler Henan Province, have made outstanding contributions to technological innovation and gas boiler.
Steam boiler superheater and steam parameters and the role of retirement: this kind of boiler 2 tons steam boiler manufacturer, I believe we are not unfamiliar to it, because it is widely used, but the site also has been conducting introduce explained. So, based on these two points, is the need to have a comprehensive knowledge and understanding of the steam boiler, in order to achieve a reasonable use of the product, and then, to play its due role, and to reflect its economic value. 1. steam boiler waste water produced, it can be discharged directly? On the steam parameters, if there is a vapor density of this? Steam boiler wastewater generated, it can be directly discharged condition for the no pollution, that is, there is no contamination of waste water can be discharged directly, if there is pollution, then, is first processed and meet emission standards in order to discharge . In the steam parameters, this is not a vapor density, and purity of steam only two evaporation. 2. Is there a superheater steam boiler, steam affect you? Is there a superheated steam boiler, steam boiler its kind produced, is very much affected, because the steam boiler with superheater to produce dry steam superheater if not, then the boiler can only produce Saturated Vapor. Therefore, in terms of superheater steam boiler, it is an important member. 3. What is the over-pressure steam boiler accident? If the steam boiler, the boiler internal pressure exceeds the safe operation of the boiler and any conditions or requirements, can be considered the boiler overpressure accident. Moreover, this is a dangerous phenomenon, if not promptly treated solve it, it will have serious consequences, so it can not be ignored, should be sufficient attention to the job.
It must be drained every eight hours. If multiple boilers share a single sewage main pipe, and there is no check valve on each boiler sewage pipe, simultaneous sewage discharge is prohibited;
Guangdong Provincial Quality and Technical Supervision regarding the development of biomass briquette boilers special work
Recently, Guangdong Province issued "Notice on biomass briquette boilers special work" (the "Notice"), requiring the province since the beginning of July biomass briquette boilers carpet Mocha by three months the complete list of developed and complete the scattered dirt biomass boilers in the province before the end of 2019, direct combustion, such as non-compliance out of chaos and rectification.
First, remediation objects
According to "People's Republic of China Air Pollution Prevention Law" and "Guangdong process boilers pollution remediation plan (2016-2018 years)", (Guangdong ring [2016] No. 12), this special work-out and the quality of the main targets include: direct burning biomass boiler, the boiler does not meet the high-pollution fuel combustion zone ban management requirements, central heating boilers dispersed within the heating network coverage, the boiler gas pipeline network coverage, the use of coal and its products the dual-fuel or multi-fuel biomass fired boiler, coal-fired boiler into a biomass briquette boilers do not meet the legal reform program, it has been approved by the people's government the right to shut down the boiler and other companies.
Second, the remediation measures
(A) strengthen the management of biomass briquette boiler
New boilers should biomass briquette Briquette dedicated biomass boilers (or dual-fuel fuel designs allowed). For the latter meet the conditions for registration of quality supervision departments also must apply for environmental procedures according to law, be put into use.
(B) strictly regulated pollutants raw material is fired boiler
Environmental protection departments should strengthen supervision of pollutant emission biomass-fired boilers molding, organize supervision and monitoring of the discharge port of inspection car, pollutant emission concentration of biomass fired boiler to reach or better than the current corresponding to the natural gas boiler emissions standard (conversion 9% oxygen content reference emission concentration), the concentration of carbon monoxide emissions of less than equal to 200 mg / cubic meter, the feed inlet video surveillance facilities biomass fired boiler is to be networked and environmental protection sector, more than 20 tons of steam biomass molded fuel boiler to be installed on-line monitoring equipment, and networking with the environmental protection departments to encourage 20 tons of steam biomass fired boiler to install online monitoring equipment. For pollutant emissions are out or do not meet the requirements dealt with by the environmental protection department according to the law, the quality supervision department cooperate with law scrapped boiler, write-offs.
Third, the time node
"Notice" announced the schedule for the remediation activities: biomass briquette boiler before June carding meet the special requirements of the boiler, the development of monitoring plans by the local environmental protection department, by supervisory monitoring, enterprise self-monitoring measures to ensure that in 2018 exhaust gas monitoring complete biomass fired boiler is in the list before the end of the boiler to investigate and punish excessive emissions.
7 to 10 months focusing on remediation biomass briquette boilers do not meet the special requirements of the boiler. Since August, the quality supervision departments throughout the province last month to the cancellation of the 5th of each month, scrap, corrective actions and a list of biomass briquette boiler re-enable the exchange to the same level of environmental protection department, the environmental protection department of the list with boiler organizations atmospheric monitoring pollutants.
In addition, quality inspection departments to be before the end of 2018, before the end of 62,019 years to complete before the end of October 2019 were 30%, 70%, to urge the rectification work 100% of the boiler problem.
After you have a list of remediation raw material briquette boilers, by supervisory monitoring, self-monitoring and other measures to organize corporate environmental protection departments in the country to receive quality supervision departments to provide complete exhaust gas monitoring within two months, to ensure that all students complete before the end of 2019 material fired boiler emissions monitoring.
Fourth, the work requirements
(A) submit the required work ledger
Listing biomass briquette boilers local quality supervision departments to the end of June 2018, is currently in line with energy-saving features of the device and safety requirements submitted to the Provincial Quality Supervision Bureau, the Provincial Quality Supervision Bureau to exchange Provincial Environmental Protection Office. The second half of 2018 --2019 end of each quarter, the environmental protection departments throughout the progress of work on the 5th an accumulation of sound required to submit the Environmental Protection Agency.
(B) a comprehensive inventory, leaving
To work closely local quality supervision departments and environmental protection departments, clear name and contact details, according to "local management, levels of responsibility, seamless, comprehensive coverage of" principle, carpet-Mocha, timely updated sound biomass briquette boiler list, the implementation of ledger-style, pin number management. A complete rectification, a pin number.
(C) strict law enforcement, supervision of implementation
Local quality supervision departments and environmental protection departments according to their respective functions, like take the time node, according to the law to carry out renovation work on the investigation, to ban the work may not be implemented, to promote the progress has lagged far behind, regulatory serious dereliction of duty, serious accountability related personnel responsibility. Provincial Environmental Protection Bureau, Quality Supervision Bureau will form a joint inspection teams fired boiler renovation work carried out around the biomass conduct spot checks, reporting the progress of work.
Overall, the Guangdong Province to seize the chaos veered to burn biomass briquette industry in recent years in existence, the name of biomass, coal and other solid chaos, both for air pollution control pollution, but also conducive to purifying biomass briquettes industry ecosystem, promote the healthy development of the industry norm.
