Details installed gas boiler combustion system that we need to pay attention when installing a gas boiler combustion system, inviting professional staff in advance of the circuit diagram design, so that when installing the status line installation will not appear unreasonable. Also, pay attention to install some fire-fighting equipment, which can provide protection for our security. Unit ventilation should generally remain the total combustion air amount at the rated load. Combustion process controller provides a separate set of contact start-stop control. May be formulated in a variety of burner start-stop loop cascade control relay 10A is a fuse, relay start-stop control stops the control terminal may be connected to the burner, may directly control the power of the burner. Both constant pressure sensor, water power, fuel, gas pressure set value is detected after the automatic controller opens. Time pressure sensor, water supply, oil, gas, and their detection circuit, alarm and found the problem immediately shutdown flame protection, the controller automatically displays the point of failure, an alarm sounds machine. Installation room oil, gas line gas boiler, boiler room should be strictly in accordance with design, specification, and should refer to the burner. Fuel system pressure test after installation is complete, should be 1.25 times the working pressure (minimum test pressure of not less than 0.4MPa). After the fuel pipe installation system should be flushed with water or steam flushing, flushing should have approved technical measures, the number of washing is not less than the secondary blowing, blow up until the clean medium, should be cleared after the purge debris and dead. After installation of fuel system should be oil circulation system-wide test. The gas should be the shortest route to the burner, the air supply pipe diameter must be larger than the constant value parts of the burner duct.

Recently, Zhongshan City, Guangdong Province, the ecological environment expanded Bureau held a working high-pollution fuel combustion zone ban will promote further urge the major companies on time and quality completion of boiler rectification task. It will be mentioned in the need to deeply Publicizing the newly revised "Air Pollution Prevention Regulations of Guangdong Province" and "boiler air pollutant emission standards" and to implement the next phase of work to expand the scope of the ban on burning zone, Zhongshan City.

District policy is to implement the ban on burning blue sky, Zhongshan City, to win the Battle of the most important, relevant departments, district towns, enterprises should pay full attention and positive action in order to "limit Forced, territorial responsibility, multi-pronged approach , coordinated implementation of the "principle, should work together to create synergy, take the following measures to ensure that all targets are met within the deadline.

According to published Zhongshan City, "about expanding the scope of high-pollution fuel combustion zone ban notice" requirement, in addition to coal-fired cogeneration thermal power plant units have been built high-pollution fuel industrial equipment must be removed or completed by June 30 this year clean energy transformation, all enterprises should actively cooperate with government departments to complete the rectification task on time and quality.

According to requirements "Boiler Air Pollutants Emission Standards" (DB44 / 765-2019), and from April 1 this year, the province's start step by step implementation of the new air pollutant emission standards boiler, new boiler effective from April 1 this year, in accordance with the different regions in which, since 1 July 2019 or 1 July 2020 to implement the new standard boilers. Compared with the original standards, new standards particulate matter, sulfur dioxide, nitrogen oxides and other pollutants received strict emission limits help to further reduce the total emissions of air pollutants.

Henan coal-fired boiler plan according to Henan authorities learned that, as of October 31 this year, to central heating in provincial cities, provincial tube county, county and other built-up areas within the area covered so the organs and institutions and railways, housing residential, hotels, baths and other coal-fired boilers are dismantled or clean the transformation of objects. 11 months ago will be completed 849 sets of 10 tons of steam coal-fired boilers and removal of the following, or the transformation of clean energy. For the clean energy transformation principle is that burning natural gas, liquefied petroleum gas, electricity, biomass briquettes, coal gas and other clean energy programs in addition to the completion of the boiler or dismantling of the unit, the province will also give some financial subsidies. Will also Chaigai boiler as markers official standard for the principle of demolition is not able to recover the use of a standard boiler. That theme boiler must be removed, the chimney must be removed, associated piping and wiring must be removed or cut off, boiler-related write-off procedures. If you can not practice the subject matter must be removed to dismantle motors, blowers and other major equipment

Greater than 65t / h industrial boiler of what air pollutant emission standards should be executed? A: The State Environmental Protection Administration, Central Division-standard [1993] No. 012 document pointed out that the emergence of a small number of parameters currently higher than GB1921-80 "industrial latest vertical laundry steam boiler parameters Series" and GB3166-82 "hot water boiler parameters Series" layer burning, stoker boiler, regardless of its use Zanan GB1327-91 execution. Therefore> 65t / h or more (except coal, circulating fluidized bed, and fuel, gas fired boilers) industrial boilers should be performed "boiler air pollutant emission standards."
