There are many coal fired coal boiler construction project manufacturer in China. ZG Boiler in China, has more than 70 years experience in boiler manufacturing and designs. And our products includes gas fired boiler, oil fired boiler, lph boiler, chain grate boiler, biomass fired boiler stoker, cfb boiler, etc.
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  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.
ZG biomass fired coal boiler construction project can be divided into chain grate boiler (also called travelling grate boiler) and CFB boiler. And our power plant boiler can use fuel like biomass and coal. Our biomass fired chain grate boiler can be divided into DZL, SZL and corner tube type.
Our case with 10-ton coal boiler construction project. Operating costs 10 tons of coal-fired boilers coal 600 yuan / ton, compared with 0.6 yuan / kg; calorific value 5500 kcal / kg; required heat 6 million kcal / hour and 10 ton boiler; coal boiler thermal efficiency 70-80 % (75% in accordance with our calculated): 10 tons of coal fired boiler 1 hour the desired amount: 6000000kcal / h ÷ 5500kcal ÷ 75% = 1455kg / h; 10 tons of coal boiler 1 hour investment costs: 1455 × 0.6 = about 873 yuan. 10 tons of gas boiler running costs of piped natural gas price of about 2.8 yuan / Nm3; calorific value of 8600 kcal / Nm3; thermal efficiency between 90% -95% (we calculated 90%); caloric needs 6 million is 10 ton boiler cards / hour, i.e. 77.52Nm3 / h; 10 tons of gas required for the gas boiler 1 hour: 6000000kcal / h ÷ 8600kcal ÷ 90% = 775.2Nm3 / h; 10 tons of gas boiler 1 hour run investment costs: 2.8 yuan / Nm3 × 775Nm3 / h = 2170 dollars.
