Guangdong Provincial Quality and Technical Supervision regarding the development of biomass briquette automatic boilerss 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.

Selection and classification of fuel gas thermal control system fuel gas automatic boilers 1. The boiler classification thermal control system (1) electric system for an electric meter instrument cluster system consists of relays, time relays, the relay program composed of program control and interlock system; manufactured by electronic control and intelligent series or digital instruments, measuring instruments display, sound and light alarm monitoring instrumentation and control system and other components. Electric instrumentation system design experience mature, the price is cheap, but it is difficult to achieve system redundancy, remote data transmission, maintenance is more difficult, more difficult to implement advanced control methods. Electric meter system is mainly used for small boilers, but the electronic control Applications for closed-loop regulation of decreasing almost been replaced by intelligent multi-function instrument, the following sections mentioned electronic control just want to take advantage of familiar industry and the series combination of a widely used instrument that time to explain the principles of the control system configuration and (2) programmable control system programmable control system is the core of programmable logic controller (PLC). Programmable logic controllers are widely used in the initial control, since the 1990s has increased the ability of process control, the programmable logic controller in the field of process control applications more widely.

Some of the causes direct impact on the thermal efficiency of horizontal steam automatic boilers of the country are carrying out a blaze of glory roaring coal to natural gas operations, the choice of horizontal steam boiler, greatly reducing the fine dust contaminated with dust, along with toxic gases such as nitrogen oxides emissions It has also been suppressed. Thermal efficiency is a key measure of horizontal steam boiler, a good start and that is that let you look at some of the causes direct impact on the thermal efficiency of horizontal steam boiler. Through research departments, the heat loss of horizontal steam boiler is very important from two aspects: the combustion air-fuel ratio is not satisfactory and Smoke and heat loss. Smoke and heat loss reduction should be modified in the tail horizontal steam boiler soot waste heat recycling install, or choose would be more leading series condensing boilers. Combustion air-fuel ratio over the substandard Analysis: common horizontal ejector-type steam boiler burner choice, without the formation of air-fuel ratio can be flexibly adjusted. Most of the horizontal steam boiler selected non-automatic strong emission burner, leading to the root causes of unsatisfactory air-fuel ratio has the following areas: air-fuel ratio is not ideal is more important is divided into two kinds of probability: When an excess of oxygen, there will be endless excessive cold air is heat conduction, resulting in increased energy consumption horizontal steam boilers, hot horizontal steam boiler efficiency decreased; when oxygen is not standard, incomplete combustion occurs, generating heat horizontal steam boiler efficiency decreased.

It works with organic heat carrier automatic boilers to be emphasized three points: the boiler organic heat carrier boiler, all these A boiler, whether familiar with and understand it? Why we raise this issue, and its main purpose is to be drawn article content, and let everyone be ready to targeted learning, to improve learning efficiency, enhance learning, so, to make their own benefit. Organic heat boiler, which can also be called oil boiler, the working fluid because the heat transfer on the boiler, or heat carrier, for the heat conducting oil, thereby to achieve a thermal energy conversion device. Further, the operating characteristics thereof, is a low pressure high-temperature operating characteristics. 1. The working principle of the major classes of organic heat boiler organic heat boiler, which is specifically as follows: coal, oil and gas and other combustible materials such as a combustible fuel, and thermal oil as a heat carrier, by circulating pump the liquid forced circulation, heat transfer is performed, so as to achieve the intended purpose and effect. The main types of organic heat carrier boiler, if divided by fuel, then the organic heat carrier for electric boilers, coal-fired organic heat carrier boiler, oil boiler organic heat carrier boilers, gas and other such organic heat carrier.
