Henan Provincial Government to respond positively to meeting the spirit of the "Blue Sky Battle Action Plan", in mid-September, the issuance of "three-year action plan for pollution prevention and control campaign of Henan Province (2018-2020 years)" ( "Program"), under provincial jurisdiction, provincial tube county (city) people's government and provincial government departments need to be strictly enforced.

A gradual reduction of the total coal consumption

1, and strictly control the total coal consumption. Strictly implement the "People's Government of Henan Province, Henan Province, on the issuance of" Thirteen Five "total coal consumption control notification program of work." Strengthen the electricity, coal, steel, chemicals, nonferrous metals, building materials and other key industries of coal consumption reduction measures to eliminate a number of energy consumption is higher than the national average of inefficient capacity.

2, to enhance coal project access threshold. In principle ban on new or expanded production capacity of pure coal, coal, iron and steel, electrolytic aluminum, cement, glass, traditional coal chemical, coke overcapacity of traditional industries, the province's non-new chemical park.

3, an alternative embodiment of the coal reduction. Strictly implement the "coal project in Henan coal consumption of alternative management (Interim) Measures", all new construction, renovation, expansion project be implemented coal coal reduction or equivalent alternative. For failure to complete the annual coal consumption reduction objectives of local, regional limits approved implementation of coal projects. In addition to cogeneration projects, the province no longer approve new production of "Thirteen Five" period coal-fired power projects.

Second, build the province's clean heating system

1, the basic realization of full coverage of urban central heating. Based on existing resources and central heating facilities, the existing large-scale heat sources and central heating pipe network in the area, in-depth investigation heating demand, and promote the rich heating capacity extends to reasonable radius and root out the potential heating, heating reduce blind spots.

2, vigorously promote clean energy for heating. Central heating pipe network coverage area, the power supply and secure place, the implementation of clean energy heating engineering, accelerate the promotion of ground source, water and air source heat pump technology, building a number of distributed energy heating project; in the natural gas pipeline network to cover the area, on the premise of the implementation of gas supply contracts, ordered the construction of gas-fired boiler room, natural gas distributed energy projects.

3, strengthen clean coal quality control. Continued to organize provincial, city, county, township (neighborhood) and village (community) scattered five coal-burning governance special inspection operations, according to the law to crack down on sales of substandard clean coal behavior.

Third, the development of industrial coal-fired facilities Chaigai

By the year 2020, and out of the basic ban coal stove cogeneration heating pipe network coverage range fired heating, drying furnace (kiln); out hearth furnace diameter of 3 meters fuels gas generator, increase fertilizer industry fixed bed coal gasifier intermittent reform efforts; focus on the use of gas furnace industrial park, they will not have to switch to natural conditions, should build a unified clean coal gas central principle; prohibition blended with high-sulfur petroleum coke.

Fourth, to promote the comprehensive improvement of coal-fired boilers

Demolition and gradually expand the boiler clean energy transformation of coal-fired range. Before the end of 2020, the province basically eliminated 35 tons of steam / h and coal-fired boilers.

Boiler Chaigai funding awards complement the implementation of the way decreasing year by year:

The completion of the coal-fired boilers Chaigai before the end of October 2018, giving 60,000 yuan / tons of steam financial awards complement;

The completion of the coal-fired boilers Chaigai before the end of October 2019, giving 40,000 yuan / tons of steam financial awards complement;

The completion of the coal-fired boiler Chaigai after the end of October 2019, no longer give financial awards complement.

1.5tph WNS series condensing gas-fired steam china boiler tube manufacturers project for the glassware industry

Founded in 1818, Libbey Inc. is a large manufacturer of glassware and it is also the standard maker of catering glassware industry in North American. With over 1 billion annual output value, Libbey operates 6 glass manufacturing factories in 5 countries on 3 continents. Libbey (China) Co., Ltd. was set up to develop the Asia-Pacific market. The glass tableware factory located in Langfang Hebei Economic and Technological Development Zone was put into production in early 2007. Its production capacity was up to 100 million per year. As a global company adhering to sustainable development, Libbey decided to update the existing gas-fired boilers to achieve low NOx emissions.

At the same time, gas china boiler tube manufacturers before running, we should pay attention:

1, gas steam boiler before ignition must conduct a comprehensive examination, including the burner and related accessories and pipes are complete good, the operation is flexible. Before the water is not required to close the drain valve, open a safety valve, allowing air furnace can be discharged. After all the examination was normal, boiler before ignition Sheung Shui, Sheung Shui to drum should be the normal water level, turn on any air, flue baffle. Start the blower, the flue of the furnace and vent purge, purge time is not less than 0.5 minutes, and then start the ignition burner.

2, the treated water injected into the gas boiler, the water temperature should not exceed 40 ℃, when the pot water level reaches the lowest level, i.e. the inlet valve closed, to observe whether the water level is lowered. After firing the pot should always pay attention to the water level, the water level will rise as a result of exceeding the maximum safe water level can be heated sewage.

Effect of china boiler tube manufacturers heat storage capacity adjustment operation when the external load variation, the temperature in the boiler and metal working fluid, the heat and other changes have occurred. When the end of the combustion so as to increase the load time to adjust steam pressure drops, the corresponding saturation temperature is reduced, a corresponding reduction in boiler water liquid heat, and the heat storage boiler water discharged at this time the metal will vaporize a portion of the boiler water itself into steam. These generate additional evaporation vapor pressure can play a role in slowing decline. Therefore, the slower the heat storage capacity of the larger the vapor pressure decreased. In contrast, when the same combustion conditions, load reduction of the vapor pressure is increased, temperature rise due to saturation, and will be a part of a metal working fluid stored heat, vapor pressure so that the rate of increase slowed. Therefore, the heat storage capacity of the boiler is beneficial to the stability of the operating parameters. However, when the boiler is required to actively change adjustment condition is changed firing rate, the boiler load, pressure, temperature, heat storage capacity due to slow changes, can not quickly adapt to changing conditions.
