rice husk steam boiler 2000kgh
The fundamental problem with the hot water boiler safety valve work process: the boiler, there is a class, boiler for hot water, it can be said that a common and common species, and, from some extent, it is also the site one of the important products, so, based on these factors, the following will work to learn this kind of boiler, that is, to explain their knowledge of the content, so as to enhance the familiar hot water boiler degree. 1. The hot water boiler, whether you want to set up sub-cylinder? And its 2.0MW, explains what? Theoretically, in the hot water boiler, which is hot water temperature is lower than the saturation temperature of 5 degrees or more and, therefore, is not to set the sub-cylinder. So, a question for which the answer is not. The hot water boiler 2.0MW, it indicates that the boiler thermal power of 2 MW, in terms of tonnage of the boiler, it is a little less than 3 tons.
Personnel to operate the boiler 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.
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  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.
Boiler scale may lead to boiler tube long run neat boiler will have a scale in the pipe, if long-term clean up the scale will greatly reduce the efficiency of the rice husk steam boiler 2000kgh and let the boiler is damaged, the worst case boiler explosion caused casualties and property safety incidents occur . In steam boiler scale will directly affect the flow of water into the heated area of the boiler and hot water blocked, water can not flow and this will affect the heat energy of the steam boiler delivery, a serious cause steam boiler exhaust gas temperature is too high, or directly cause burst pipes. If the continuous use of the steam boiler 2-3 months, will have a general scale, the water quality may appear different scale each region there will be some time lag, but it will certainly have an impact on the scale steam boiler, please use the majority of boiler those who do not take it lightly. Recommended boiler water hardness is relatively soft water, it will reduce the impact of scale arise.
