To continue to improve air quality and protect people's lives and health, Hainan Province, issued a "Hainan Air Pollution Prevention Regulations" (hereinafter referred to as "Regulations"), a clear implementation of the total coal consumption control system, and gradually reduce the amount of coal consumption, phase out existing coal-fired units. "Regulations" since March 1, 2019 into effect.
"Regulations" put forward specific requirements for coal and other energy pollution control.
A prohibited import, sale and burning of coal does not meet quality standards; prohibited the import, sales do not meet standards of quality petroleum coke; prohibition of burning petroleum coke. Above the county level department in charge of market supervision and management need to be strengthened coal, petroleum coke quality management, from time to time on coal, petroleum coke quality sampling.
Second, the people's government above the county level market supervision and administration departments shall, jointly with relevant departments in charge of the environment, industry and information technology, etc. According to China's Hainan Province and the relevant provisions to strengthen the supervision and management of boiler production, import, sale, use, etc., do not compliance with environmental standards or requirements shall not manufacture, import, sale and use. Phasing out coal-fired boilers. Existing clean energy such as natural gas-fired boilers, furnaces, low NOx combustion should be completed within the prescribed period of transformation of the people's governments above the county level department in charge of the ecological environment. New clean energy such as natural gas-fired boilers, furnaces and other facilities shall pollution control measures such as the use of low NOx combustion.
Third, the central heating has been implemented for the work (production) business park, a ban on new construction, renovation, expansion of decentralized heating boilers, heating boilers should be dispersed in the original city, county, autonomous county people's government department in charge of market supervision prescribed period in the demolition; work not yet implemented central heating (production) business park has heating demand should be in the city, county, central heating implementation as soon as possible within the time limit prescribed Autonomous County people's government department in charge of market supervision and management, and removal of the original dispersion heating boilers.
Compared down, condensing boiler has so many benefits, the price is certainly higher than ordinary boilers. After all, condensing boilers also called a set of technology and quality in one of the elite. But expensive is certainly expensive, makes sense, in addition to the environmentally friendly energy condensing furnace life is also higher than ordinary boilers, more cost-effective.
Pharmaceutical Pharmaceutical automatic cast iron boiler maintenance boiler maintenance needs what needs to be done to do what recent customers find us fast boiler, which inspection and maintenance of boiler maintenance consulting laboratories do? To solve this problem, our technicians providing answers. 1, external to the inspection process in the boiler low nitrogen periodically check the state of the external boiler, the boiler housing to ensure that no traces of rust corrosion occurs, and the connection between the various parts of the loose without loosing phenomenon, the appearance of the boiler deformation does not appear. In addition, welds and heat affected zone of the boiler also check there is no defects such as cracks, where necessary, be checked using the surface inspection or other testing methods. 2, a low nitrogen boiler internal inspection requires a lot of internal inspection of the site, wherein for the previous test of the defective parts, the same test methods to be employed, or increasing the appropriate inspection method of flawed or has been subjected to defect repair site focus review retest; head low nitrogen boiler tube plate, furnace combustion chamber and a return header and also must undergo periodic inspection; combustion apparatus in addition also check whether there is a boiler burning, deformation phenomenon. 3, the test needs to be tested to a predetermined pressure boiler pressure tightness and strength member is performed when checking for a low pressure nitrogen pressure boiler inspection, making the hydraulic inspection time to pay attention not to participate in the communication member of the hydrostatic test (such as outside the scope of boiler pipes, safety valves, etc.) should take credible measures to cut off. If the check is carried out at low temperatures, then we will take effective measures to freezing. These are some of the content should be periodic testing of pharmaceutical boiler, the boiler at the time of the pharmaceutical inspection, testing sequence is also very important, usually the first internal inspection, water pressure inspection, do an external examination.
l, before installation of the pipe rigorous re-examination, have a welding process of welding instructions, welding quality to meet the design requirements. Pipeline after the installation of the pipeline to pass the ball test to ensure that qualified rate of 100%. 2, strengthen water quality management, water softening class laboratory once and meet water quality standards, regularly check the content of scale and elimination of sewage on a regular basis. 3, water wall tubes and pipes to regularly check the exhaust convection, found deformed or thinned tube to be replaced, keeping in mind that the quality of maintenance, must comply with regulatory requirements. 4, control the automatic cast iron boiler may not work overload (specified limit), pay attention to the furnace combustion process, to ensure uniform and stable combustion.
