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.

Environmental issues boiler heating surfac area countijg formulla assembly Note: introduce a predetermined environmental protection boiler drum of the drum to be assembled longitudinal weld, the weld ring is assembled to the assembly welds and weld splicing head or both elements should satisfy the following requirements: the longitudinal seam or seal the actual welding seam edge deviation head sides of the steel sheet is not greater than 10% of the nominal thickness, and not more than 3mm; when the thickness is greater than 100mm, of not more than 6mm. Deviation of the actual edge seam on both sides of the steel sheet ring is not greater than 15% of the nominal thickness plus 1mm, and no greater than 6mm; when the thickness is larger than 100mm, no more than 10mm. Two abutting element or plate have different thicknesses and the edge of the book cut, treated according to the same plate thickness, the above-described nominal sheet thickness means; butt plate of different thicknesses, but with no thinning, the nominal thickness of the aforementioned finger planks . Any difference between the maximum inner diameter of the same cross-section and the minimum inner diameter of the drum should be not more than 1% of the nominal inner diameter. Angularity drum longitudinal seam should be no greater than 4mm. If the pressure detecting element via a weld joint defects found unacceptable, welding unit shall find out the reason, the development of a viable repair program to rework. Before welding defects should be completely removed. After welding, welding zone should be done appearance inspection and nondestructive testing. Heat treatment after welding element requirements, should be done after the welding heat treatment after welding. Rework the same position should not exceed three times. Repair parts, frequency and circumstances shall be deposited in the boiler repair product technical file. In the economic and environmental positive impact gas steam boiler

What are the advantages of gas-fired boiler heating surfac area countijg formulla units or many large enterprises will choose to use a good quality gas boilers, it is to be able to play a good heat conduction to cope with their work, with its growing number of needs also put forward higher requirements for gas-fired boiler, so today we have to introduce the next advantage with a gas boiler which. First, the main role of fast heat conduction gas boiler is to function as thermal conductivity and transmission, which itself has a strong function of thermal conductivity in a short time will be able to quickly transfer all kinds of heat, for some relatively large area of ​​the factory or business to He said it was a very good choice, because it only needs to be powered on or after connection to the machine can well play a relevant role is very convenient. Second, the thermal effects good addition to the above advantages gas boiler also has the advantage of good thermal effects, as long as it can be a very good heat transfer to each product and transport space save people a great time and effort, it's a good thermal effects also include the ability to let it play a lot of long-term thermal conductivity of heat transfer function, which also can be a good resource to let people enjoy the convenience of saving them. Third, the product price is right is a large gas-fired boiler boiler but its price is quite capable accepted by the public, people can use it in many industry sectors to complete the work, especially some of the start-ups in particular can be selected or units inexpensive gas boiler to use this in itself can also help save a lot of money, with lower prices and a strong performance also attracted a lot of customers for the gas-fired boiler to rush to buy. These are the gas boiler has three major advantages, we praise gas boiler by many consumers, people want to buy it to use better follow-up work, so when consumers will choose the contrast compare it to the price advantage and can consult the relevant staff.

15 tph SZL biomass-fired steam boiler heating surfac area countijg formulla for textile factoryLongyang Textile Printing and Dyeing Co., Ltd. is a textile processing company, whether dyeing, drying, sizing or printing are inseparable from the support of steam boilers. Since the textile industry, in which Longyang Textile Printing and Dyeing Co., Ltd. is involved, consumes a large amount of fuel, low-cost and environmental-friendly fuel is the first choice for textile manufacturers. The steam quality of steam boiler has a decisive effect on the product quality after dyeing and drying in clothing textile mills. Generally the consumption of steam boiler fuel in the textile industry is relatively large. Therefore, choosing steam boilers can not only effectively improve the quality of textiles in textile companies, increasing production efficiency, but can also reduce labor costs and operating costs of steam boilers. The 15 tph SZL biomass-fired steam boiler produced by ZOZEN boiler purchased by Longyang Textile Printing and Dyeing Co., Ltd. not only has high thermal efficiency, but also has low operating costs. Fully or partially replacing coal-fired boilers with our biomass-fired steam boilers can bring substantial economic returns to the company.
