coal fired condensing vacuum hot water boiler

coal fired condensing vacuum hot water boiler

Here's a look at what the characteristics of the vacuum boiler. 1, the internal structure will not corrode due to the vacuum boiler negative pressure vacuum state, it is completely isolated from atmospheric pressure, so the configuration of each unit boiler exhaust pump will continue to discharge the steam inside the unit, not within the organization structure caused by corrosion, so the vacuum phase transition boiler in terms of durability performance is quite good. 2, the different secure and normal pressure boilers, vacuum boiler air is evacuated children because the inner container forms a vacuum environment, so its use in the process of working in a vacuum furnace-like body is not generated due to heat expansion, but it does not belong to the pressure container, and therefore there is no risk of explosion.

The difference between the atmospheric pressure hot water boilers, hot water boilers vacuum? Currently, many have adopted residential district heating boilers, hot water boiler performance and therefore plays an increasingly important role in the heating of the residents. The most common on the market are coal fired condensing vacuum hot water boiler and boiler pressure hot water boiler. However, many consumers know these two hot water boilers thorough enough, there may be some bias. A, different security present, primarily professional vacuum hot water boiler hot water boiler, a hot water boiler internal negative pressure can achieve the purpose of rapid combustion temperature, while by changing the configuration of a vacuum hot water boiler may be related to atmospheric hot water boiler. Therefore, security is more obvious. However, when using hot water boiler pressure hot water boiler as long as the use of some type of guarantee ventilation, and therefore pressure hot water boiler is particularly safe and reliable. Second, due to the small amount of water heating efficiency of different vacuum hot water boiler, a water requires multiple cycles fewer burner heated hot water boiler and the atmosphere of a large container only opened once the burner can achieve a good heating effect can be efficient heating. Hot water boiler circulating water and atmospheric pressure hot water boiler. Thermal efficiency of the furnace is higher than the thermal efficiency of the vacuum hot water boiler. Third, the complexity of the equipment in order to ensure different vacuum, vacuum hot water boiler must be installed infrastructure series a vacuum pump, but the average hot water boiler pressure control device need not be employed to maintain the vacuum. Therefore, no complicated control equipment required personnel to operate more simple, the complexity of the boiler equipment in use also have greater advantages, meet the needs of more consumers.

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.

Gas-fired steam boilers of different types and their advantages on the common market gas steam boiler model, what does? According to data accumulated over the years, the statistics, the results are as follows, for your reference to understand. WNS fuel gas steam boiler, low cost, the implementation of the pipeline, so that lower gas prices, fuel cost decreases; the model of high boiler combustion efficiency, fuel savings, investment buying low fuel costs; the whole side pull butt welds, boilers the use of safe, long life, low maintenance costs. High efficiency, there is arranged a tail flue gas condensation recovery, can effectively control the exhaust gas temperature, high thermal efficiency of the boiler; using automatic burner, water continuous electric adjustment, high combustion efficiency. SZS fuel gas steam boiler, with international popular three-pass shell type, all wet back structure, large volume combustion chamber design, burning more fully. Internationally renowned burner, combustion chamber all-corrugated furnace structure, both to strengthen the flue gas disturbance, but also increases the radiation heat transfer area. Not only increases the stiffness of the furnace, and effectively weaken the expansion stress of the furnace; enhance both heat transfer, but also to promote the fuel combustion within the furnace. Vacuum gas hot water boiler, high safety, vacuum boiler because the phase change medium flow system below atmospheric pressure, absolute pressure inside the unit is running is 0.02 ~ 0.08MPa, the unit is in a vacuum state, and thus the explosion does not occur. Long life, internal boiler fouling does not occur, increasing the life of the boiler use. Heat exchanger portion with stainless steel, corrosion-resistant, the design service life of 20 years. High degree of automation, the use of the control device and mechatronic joint control programmable logic controller. Long life, scientific product design, advanced processing technology and strict quality control, all factory production of boiler equipment. The advantages of gas steam boiler in recent years reflects the more comprehensive. Exacerbate air pollution causes the gas steam boiler into the market faster. Gas-fired steam boiler is a clean energy, natural gas fired industrial boilers, and with the traditional burning of fossil fuels such as coal boiler has unparalleled advantages in comparison. Natural gas boiler steam boiler market development trend in the future, the future market development of industrial boilers except by factors affecting the pace of development of our national economy and the scale of investment, etc. In addition, more and more restricted energy policy and energy-saving, environmental protection requirements.
