papermaking fuel hot water vacuum boiler supplier

Winter is the peak heating heating, but also prone to accidents of special equipment such as papermaking fuel hot water vacuum boiler suppliers. To effectively prevent and curb the occurrence of accidents, equipment thorough investigation to eliminate safety hazards, Hunan Province to carry out safety hazards investigation work in the province within the boiler, boiler equipment and punishes the security measures are not in place.

Yueyang City bearing the brunt of the provincial government in response to the call for in food, pharmaceutical processing industry, boiler equipment, pressure vessels, pipelines, etc. investigation and remediation, further investigation and security risks, strengthen supervision, which ensures safe operation of special equipment.

Zhuzhou City, the relevant departments to implement the special equipment safety responsibility, collective interviews conducted meetings, some special equipment overdue inspection or rectification in place of business risks not to be interviewed. In order to urge them to get inspection reports in order to restore operation, to ensure the safe use of special equipment. But also warned of these enterprises, if not through legal regular inspections, not only safety and production are not effectively protected, will be severely punished.

Wuxi vacuum papermaking fuel hot water vacuum boiler supplier vacuum boiler price how much money is currently more and more recognized by the market and use. Vacuum boiler installation does not require inspection, transported to the scene, after the commissioning run. Convenient, welcomed by the enterprise and business. This is not a hotel in Wuxi recently wanted to supporting the needs of hot water, but due to space constraints, large-scale boilers are unable to enter. So be prepared to purchase vacuum hot water boiler to protect the hot water. After the fast boiler and the Wuxi hotel to communicate the exact amount of heat needed to the hotel, through accounting, the hotel uses two parties can quickly vacuum boiler. The price of one ton vacuum condensing hot water boiler is about 80,000. Two, the cost of procurement at around 16 million.

what do you know about vacuum hot water papermaking fuel hot water vacuum boiler suppliers?

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.

Water quality vacuum hot water papermaking fuel hot water vacuum boiler supplier is what vacuum hot water boiler quality requirements: a body of water to be a softening of the heat medium, late life without supplements. Conventional boiler water quality standards and in fact the same, particularly, a vacuum hot water boiler water quality requirements are the following criteria: 1, the furnace as a heat medium water in the furnace, the whole process is not out of the boiler operation, the increase or decrease, It closed only in a vacuum chamber of the boiler, heat transfer between the heat transfer tubes and the boiler heat exchanger. 2, the cooling water circulating device from high temperatures, less demanding quality of the circulating water. 3, the heat medium furnace needs completely deoxygenated pure water. The only way to avoid the furnace corrosion and scaling. Thus, the boiler water quality is the key, be sure to choose water quality standards, so the life of the boiler over 20 years, or even longer. High speed side vacuum heat produced by the hot water boiler efficiency, non-polluting cleaning operation, in line with low nitrogen emissions requirements. long lasting. Welcome to inquire.
