2019 best selling small coal fired boiler
Today I saw that when the capacity is the same, the furnace of the oil-fired 2019 best selling small coal fired boiler is smaller than that of the coal-fired boiler. Why? The specific reasons are as follows: the size of furnace volume, after the boiler capacity is determined, mainly depends on the volume of heat load. The size of the volumetric heat load is mainly determined by the type of fuel. After the fuel enters the furnace, it will take a certain amount of time to burn out. Fuel is usually required to burn out before it leaves the furnace. It is obvious that pulverized coal will burn longer than oil, that is, the flame of coal combustion will be longer than that of oil. In order to ensure the long-term safe operation of the boiler, it is necessary not only to prevent the slagging of the boiler, but also to make the temperature of the flue gas at the furnace outlet begin to change compared with the ash in the flue gas The temperature is 50 ℃ lower than 100 ℃ to prevent slagging at the furnace outlet and subsequent convection heating surfaces. The ash content of coal is more than that of coal-burning furnace, and the flue gas temperature of furnace outlet is 1050 ℃ and 1100 ℃. There is no danger of slagging in the furnace because of the low ash content in the oil, and do not consider the slagging problem of the slag discharge tube at the exit of the furnace, so the smoke temperature at the exit of the furnace can be higher.
When coal-fired 2019 best selling small coal fired boilers, four matters requiring special vigilance: the highly polluting coal-fired boilers transformation process, can be said boiler industry mainstream major event. General common is the transformation of coal-fired furnace gas-fired boiler, the coal to change the high fuel costs, as well as on the environment caused serious pollution problem, not a small project, you need to pay attention to the transformation of every aspect of a good safe and effective boiler close with, in order to avoid a failure of the transformation occurred. 1, the original boiler boiler before carrying out the demolition work will require the original host and auxiliary boilers were removed, concrete demolition work carried out by professional staff, in order to more quickly complete the demolition work, but also to prevent the removal process after the accident 2, note that the boiler pressure capacity of some small coal-fired boiler into a gas-fired boiler, also changed the original state of combustion, combustion becomes negative as positive pressure combustion; this process requires special attention throughout the furnace wall the structure and sealing, the sealing function properly may cause the boiler could not withstand the pressure due to the transformation, and accidents. 3, furnace renovation precautions in many cases will change when coal gas, because of poor atomization or incomplete combustion of fuel remaining in the furnace, the slightest mistake will cause fire or explosion; it is to be in the transformation is complete installed in the appropriate parts of the blast doors to prevent the explosion accidents; while additional ignition and flameout protection device to ensure the safe operation of the boiler. 4, after the transformation is complete when the test is completed after the transformation of the boiler, also requires complicated testing to confirm their safety test method is commonly used for the transformation boiler high pressure stress tests, the test and reached after the use of standards, it is considered as completed the transformation boilers.
Guangdong Provincial Quality and Technical Supervision regarding the development of biomass briquette 2019 best selling small coal fired 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.
Tell you what fuels are environmentally friendly 2019 best selling small coal fired boiler environmental protection boiler fuel for what? Many customers mentioned this problem, it seems everyone is still very concerned about this issue. These are summarized in environmental protection boiler, after reading it I believe you have a clear answer to this problem. First to note is environmentally friendly boiler is a more general concept. It is not classified according to the fuel used, but to a variety of standard boiler flue gas emissions to meet state regulations. So what are environmentally friendly boiler fuel to use it? Commonly used natural gas fuel, diesel fuel, electricity, methanol and the like. Natural gas is the most important environmental protection boiler, its fuel natural gas is a clean energy, combustion products discharged after treatment safety. Natural gas boiler maintenance costs of environmental protection is very low compared to the energy efficiency of is very high, such as our gas-fired thermal efficiency can reach 95%. This boiler is the government's most important eco-friendly boiler. Environmental protection boiler fuel diesel fuel use in general, because of the relatively low price of diesel, sulfur dioxide and other acidic substances produced by burning it after treatment can be safe discharge standards, supporting measures that it needs storage tanks, maintenance costs are lower thermal efficiency up to 90% or even higher. Electric heating boilers are environmentally friendly boiler, wire and cable facilities is required, it is zero pollution, low maintenance costs, but the state has requirements of energy conservation, power cuts in some places the situation may occur, especially in summer the peak period. This is also where you need particular attention. High energy-efficiency boiler hot methanol, facilities storage tank is required, but also the Government's strong support for environmental protection boiler. Over the years our country is more fog and haze, especially in northern areas and even worsening trend. This has aroused widespread concern. Haze days gives direct harm that affect people's mood, who see the blue sky not feel comfortable? I believe you have such an experience. Now the country strong regulation of air pollution, to govern from the source, many regions have issued a specific task, some regions have become a ban on coal zone, small gas boiler is accelerating the demolition work, the Ministry of Environmental Protection inspection teams to all designated areas can be examined, found to have concealed false hair had ordered its rectification. Government efforts to organize air pollution is evident. Now environmental protection boiler became the new alternatives, it is to advocate for and support the government. Through the above energy-saving boiler to summarize your introduction, I believe you are what fuel boiler and environmental protection have a deeper understanding.
