January first, Henan Province issued "the transformation of traditional coal chemical industry development action plan" (the "Program"), to promote the province's pollution prevention campaign of three-year action plan to speed up the traditional coal chemical industry (ammonia, methanol) industry to green transformation, to achieve high-quality development.
First, strictly control new capacity
Adherence to the red line capacity, traditional coal chemical enterprises prohibit new construction, new capacity expansion projects alone, is strictly prohibited without permission around the building does not meet the requirements of the industrial layout plan of coal chemical project in principle. The province's coal chemical projects and intensive clean-up, but according to the specified time limit has been approved to start construction of the project in principle, to construction, relocation and renovation projects must be upgraded into the base or campus planning. By 2020, the chemical industry out of the fixed bed coal gasifier intermittent exit single set of devices 300,000 tons / year of synthetic ammonia production capacity. Strict safety, fire safety, environmental protection, energy saving, water administrative licensing, implementation of the project safety, environmental protection facilities "three simultaneous" (designed, constructed and put into use) system, and resolutely shut down energy consumption, environmental protection, safety, quality, technical non-compliance enterprise. Strict implementation of the regional total energy consumption, pollutant emissions control requirements, upgrading of coal coal project be implemented reduction or equivalent alternative.
Second, increase the relocation and reconstruction efforts
Further promote the densely populated towns of dangerous chemicals production enterprises and urban built-up areas heavily polluting industrial relocation of enterprises, the implementation of an intensive investigation, the establishment of management accounting, according to "a business a policy" during mode classification advance. Priority to promoting the urban area of coal chemical industry relocation, conversion or quit, not in the urban area but not in the business park to gradually move the park, according to the specified execution be discontinued or phased out. Close to exit the business enterprise to achieve the "two off three clear" (cut industrial water, electricity, removal of raw materials, products, production equipment), select the transformation of the enterprise to implement the upgrading of the standard industry benchmark, to off-site relocation According to large-scale, modern principles move into the province for involving chemical industry gathering area. Relocation upgrading of enterprises, projects and equipment should be encouraged to reach equipment industry access standards and conditions specified in the Guiding Catalog of Industrial Structure Adjustment, the use of large-scale continuous pressurized gasification plant, ammonia production capacity to 300,000 tons / year and above, coal methanol production capacity reached 100 million tons / year and above, the main push large-scale equipment.
Third, the implementation of green transformation
Before the end of 2019, coal chemical enterprises fully completed VOCs governance. And comprehensively promote the chemical industry equipment static and dynamic sealing points, storage, handling, waste water systems, unorganized process emissions and non-normal operating conditions and other root causes of remediation. As requested, the timely completion of the coal chemical industry waste discharge permit issued by the work, companies must comply with the behavior of the sewage discharge permit clear conditions, various types of environmental inspection found violations, strictly and severely investigated and dealt with as soon as possible in place. Based on "clean production audit approach", the implementation of coal chemical enterprises compulsory clean production audit coverage. Required to implement risk control measures to close the relocation of enterprises left over land.
Both of them work with a high efficiency. Compact structure and easy installation ensure efficient, clean, economic, safe and stable diesel fired industrial boiler operation, therefore, it is widely used as an energy-saving and environment-friendly equipment in industry.
Interest in circulating fluidized bed (CFB) combustion, as an alternative to PC combustion, has been steadily increasing. AlthoughCFBdiesel fired industrial boilersas large as 300 MWe are now in operation, they are drum type, subcritical pressure units. With their sizes being much smaller than and their combustion temperatures much lower than those of PCboilers(300 MWe versus 1,000 MWe and 1600 F versus 3500 F), a conceptualdesignstudy was conducted herein to investigate the technical feasibility and economics of USCCFBboilers.
The full automatic gas-fired boiler has the advantages of one-button operation, manual operation, simple installation, convenient operation and automatic operation. As an all-in-one machine, manual mode can be set up. And the tail flue can be installed with condenser to achieve waste heat recovery and improve boiler efficiency. It truly achieved over-pressure interlock and protection leakage protection, water shortage and over-current protection, as a gas safety housekeeper well received market praise.
1, the working principle of widely used gas-fired boiler is similar, the common products of the same kind have definite limits to the use area, and the use of automatic gas-fired boiler is extremely extensive, including the supply of production gas for food processing, printing and dyeing, pharmaceutical and so on; Medical institutions provide disinfection gas; for other enterprises, institutions, hotels and so on to provide heating steam; but also through the water tank to provide hot water for life, so that a machine can be used more affordable and practical.
2, why can fully automatic gas-fired boilers realize the automation of water supply and heating in sanitary baths? For example, taking the plumbing water supply as an example, the water flow sensing device of the gas-fired boiler can accurately feedback the quantity of the sanitary bath water, that is, the sensor carries on the timely return of the plumbing water temperature, and the professional gas boiler company introduces the supply. After receiving the microcomputer, the intelligent and accurate control of the gas flow rate is realized so that the hot water is continuously supplied, and the constant temperature is guaranteed so that it can enjoy the bath without manual intervention.
3, the main reason why the combustion frequency conversion green engine fully automatic gas-fired boiler is popular in the market is mainly due to its burning frequency conversion, which is called "green engine" and "China environmental protection products" by industry insiders. For example, the fully automatic gas-fired boiler uses unique combustion frequency conversion, completely based on the actual temperature of the room, according to the temperature difference set by the user to intelligently control the combustion power and keep the temperature at the user's set value. So it provides a new mode for heating.
