Recently, located in Yan'an City, Shaanxi Province, Huanglong held removal of coal-fired boilers mobilization meeting, and promote the coal-fired boiler, "clear" work, Huanglong improve the overall air quality of the environment. The meeting was chaired by the Deputy Mayor Cao Zengjun, County Authority, Environmental Protection Agency, the Public Security Bureau and other coal-fired boilers Chaigai leading group members of the unit involved in coal-fired boilers and Chaigai of 16 enterprises and units attended the meeting.

At the meeting, urban management bureau announced the "urban transformation of coal-fired boiler demolition plan", and county coal-fired boiler demolition work arrangements for the deployment. Program pointed out, the county government before the end of June to remove their coal-fired boiler steam tons per 20,000 yuan subsidy standards in accordance with the relevant provisions of the provincial coal-fired boilers Chaigai subsidies, Chaigai completed in the first six months to the end of August unit task of tons of steam per 10,000 yuan subsidy standards, after the completion of the end of August Chaigai units should be punished to the unit in addition to the removal of subsidies, the person in charge accountable.

A coal-fired boiler Chaigai work is the key point to win the Battle of the blue sky, Huanglong is an important measure to improve the quality of atmospheric environment, the relevant units should fully understand the importance and urgency of the boiler Chaigai work, according to "own boiler demolition themselves, change themselves, government agencies take the lead in demolition, lead change, limited time limit must be removed, must be changed "requirements, implement them.

Second, the change involved units to firmly establish the overall awareness, to overcome the luck, to seize the opportunity boiler Chaigai premium policy, a reasonable choice of the transformation of the way, adhering to standards, early arrangement, early deployment, early start.

Third, the government supervises the room should work together with urban management, environmental protection and other departments, inspectors conduct regular supervision, to dismantle ineffective, slow-moving unit, to be criticized, and timely feedback evaluation to do, do you want to do a good evaluation appraisal work; County JISC to errant Chaigai, affected units and individuals county atmospheric objective assessment of the results, in accordance with the "air pollution prevention of accountability measures" be accountable, accountability, ensure on schedule to complete the work Chaigai city coal-fired boilers.

what do you know about vacuum hot water boilers?

1. What is a vacuum hot water boiler? Answer: so-called vacuum hot water boiler, also called vacuum phase change hot water boiler. When the boiler is working normally, the inner medium pressure of the boiler is lower than the atmospheric pressure, and the cold water is heated by phase change heat. Vacuum sealing inside the body of vacuum hot water boiler, negative pressure combustion of heat medium water, steam exchange between steam and heat exchanger, high heat efficiency, one-time treatment and perfusion of heat medium water in factory, no need to replenish water in operation. The unique design of vacuum hot water boiler has formed the characteristics of safety, stability and so on.

2. The composition and structure principle of vacuum Hot Water Boiler? Answer: the furnace body of a vacuum hot water boiler is divided into two parts: the upper part is a vacuum chamber (negative pressure steam chamber), and a tubular steam-water heat exchanger is installed in the space to heat the circulating water flowing through the heat exchanger. Operation principle: during the operation of vacuum hot water boiler, the heat medium water inside the furnace under negative pressure of vacuum absorbs the heat energy released from fuel combustion, boiling vaporizes into low temperature steam, and the low temperature steam rises to meet the system circulating water in stainless steel heat exchanger. Heating circulating water to the user for heating or sanitary hot water. The water vapor itself is cooled and condensed into droplets falling onto the surface of the heat medium and then heated again, thus completing the whole cycle. Heat medium water The cycle of "boiling = evaporation = condensation = heat medium water" is constantly carried out in the enclosed body, so there is no need to replenish condensate water and there is no danger of empty burning. The condensation heat transfer coefficient of steam-water condensation in vacuum hot water boiler is the highest in all heat transfer conditions.

3. What is a vacuum? Answer: vacuum state does not mean absolute pressure is zero, as long as lower than external pressure, can be called "vacuum". For example: vacuum boiler operating inside the shell is debugged as vacuum and maintained between-375pxHg--76mmHg.

4. What is vacuum? A: vacuum refers to the degree of gas rarity in vacuum, usually expressed as "high vacuum" and "low vacuum". High vacuum means good vacuum, low vacuum means poor vacuum. The value of vacuum degree indicates that the actual value of system pressure is lower than that of atmospheric pressure, that is, vacuum degree = atmospheric pressure-absolute pressure. International standard unit of vacuum: Pa (Pa).

5. Why is heat medium water in vacuum hot water boiler heated in vacuum? Answer: the boiling temperature of water is different under different pressures. Under an atmospheric pressure (0.1Mpa), the boiling temperature of water is 100 ℃, while the boiling temperature of water is 4 ℃ under 0.8Kpa pressure. The vacuum hot water boiler works within the pressure range of vacuum degree 2.67Kpa~66.6 Kpa, and the corresponding saturation temperature is 15 ℃ ~ 85 ℃. Therefore, in vacuum, heat medium water is easy to boil and vaporize.

6. The origin of vacuum hot water boiler? A: the basic principle of vacuum hot water boiler was born in 1972 at Zurich University of Technology. In 1975, Japan's TAKUMA Company developed a vacuum hot water boiler on the basis of the principle, which was patented for invention, and was gradually popularized all over the world. This technology has been developed and developed by Korean enterprises, and South Korean TAKUMA, has appeared one after another.

Which is good vacuum boiler manufacturer currently producing vacuum boilers on the market, manufacturers still have a lot of. For manufacturers who want to purchase the vacuum boiler, it must be detailed for the comparison of differences between the plurality of vacuum boiler. It is selected after comparison to high cost of manufacturers. In this case, for boiler manufacturers it is necessary. Because many of the procurement of boilers companies want to know are good for boiler manufacturers Which vacuum. For businesses, you want to choose a higher cost of vacuum boiler manufacturers, then you first need to vacuum boiler manufacturers Which is good for corporate brand awareness to a detailed understanding of, because good visibility, good brand boiler manufacturers for the enterprise, whether it is pre or after-sales service is very helpful. For businesses, you want to choose a vacuum boiler manufacturers, the most important thing in the field of boiler manufacturers to conduct field investigation, and after a detailed comparison between the various manufacturers can be drawn vacuum boiler manufacturer which home good detailed answers.

Henan local structure vacuum boiler furnace fast vacuum hot water boiler is divided into two portions, wherein the lower half of a structure similar to the second and third boiler shell flyback steam boiler, i.e. heating surface and furnace flue thereof; and the top portion a vacuum chamber (vacuum vapor chamber), which is provided with a tubular interior space of the vapor - water heat exchanger for heating circulating water flowing through the heat exchanger. The operating principle: vacuum hot water boiler is running, the negative pressure in the vacuum furnace body heat medium water absorbs heat energy released by burning fuel, Boiling water circulating system encounters a stainless steel heat exchanger of the low temperature steam, low temperature steam rises, heating recycled water to users for heating or hot water. Itself is cooled steam condenses into water droplets fall to the surface again after the heating medium is heated, thereby completing the entire cycle. Heating medium water constantly in a closed body of "boiling evaporation == == == heat medium condensed water" cycle, so no condensation water supplement, dry and no danger. Vacuum hot water boiler using soda condensation heat, all heat exchangers operating condition, soda condensation heat transfer coefficient is the highest.
