coal fired industrial vacuum hot water boiler

coal fired industrial 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.

Vacuum gas boiler introduce vacuum gas boiler Product Description: Vacuum gas boiler is the use of water at different pressures, the boiling temperature characteristics vary to carry out the work. At one atmosphere, the boiling temperature of water is 100 deg.] C, and under a pressure of 6mmHg, the boiling temperature of water was 4 ℃. Vacuum hot water unit is operating in the pressure range 200mmHg ~ 500mmHg, the corresponding water temperature was 66 ~ 88 ℃, hot water under pressure in the vacuum of the work unit, the combustion temperature of the heat medium water temperature rises to saturation, and generating steam in the water of the same temperature. At this time, through the heat exchange (heating or hot water) inside the water, the cold water in the steam tube outer tube is heated in hot water, and passed to the user, and the water steam outside the pipe were cooled and condensed back to water is heated water drops , thereby completing the cycle. The main features; vacuum hot water units always run under negative pressure, never inflated the risk of explosion, with safety and reliability atmospheric pressure boiler has unmatched; built-in stainless steel heat exchanger, heat transfer efficiency, water quality cleaning; built rope stream smoke tube sheet, increasing the effect of heat transfer, so that a more compact structure; imported burner, combustion efficiency, noise, low emissions, to achieve the requirements for a class Country; integral with a square configuration, overall spraying, shape compact appearance. Smoke tube equipped with a helical spoiler, heat strengthen, improve boiler efficiency and reduce operating costs. Indirect heating: main body of negative pressure, the system pressure; large furnace technology: effective to increase the area of ​​heat radiation unit, reducing the NOX emissions; high water boiler water, inside the body to ensure that never scaling, corrosion. Boiler and heat exchanger integrated design, saves space and greatly reduce floor space. Shell type using three return all wet back structure, dynamic heating, heat sufficiently. Low temperature boiler operation under negative pressure, safe and reliable. Automatic control system, no special duty. Imported burner, combustion efficiency, noise, emissions low. Unique pulse level detection circuit structure, reliable performance. Inlet / outlet water temperature display makes it easier to grasp the boiler operating conditions and systems. High centrifugal glass wool insulation using multi-layer, heat loss. Protection: 1, the boiler has a voltage high, ultra-low protection, when the supply voltage exceeds the normal range, the alarm and automatically cut off the power boiler. 2, the boiler has a temperature sensor fault protection, each boot, the boiler control system first detection sensor condition, such as abnormal boiler is automatically cut off power and alarm. 3, the boiler having a water alarm function: When the boiler water level is below the safety level pot, the boiler automatically cut off power and alarm. 4, the burner flame failure alarm 5, overpressure sound and light alarm 6. boiler burner motor overload, fault protection 7. Automatic shutdown protection, as follows: a) a burner failure automatic shutdown, manual reset b) very low gas pressure automatic shutdown, manual reset c) automatic overpressure boiler shutdown, manual reset power d) of the safety interlock device interrupt automatic shutdown, manual reset heating gas boiler

Vacuum hot water boilers and pressure hot water boiler specifically what is the difference Today, many are unified district heating boiler combustion modes of supply of hot water, hot water boiler performance and therefore plays an increasingly important user of heating role. The most common on the market are coal fired industrial vacuum hot water boiler and boiler atmospheric hot water boiler. However, many consumers these two hot water boilers may not have a deep understanding. First, security is now different professional vacuum hot water boiler hot water boiler main purpose of the internal trigger negative pressure hot water boiler can achieve rapid, constant temperature, but also by the vacuum hot water boiler pressure hot water boiler structural changes related So special and safe. However, good pressure hot water boiler hot water boiler in use only local ventilation, it is particularly safe and reliable pressure hot water boiler. Second, due to the small amount of water heating efficiency of different vacuum hot water boiler, the need for multiple cycles of heating burners, boilers, hot water boiler pressure vessel can be opened with just one burner, in order to achieve a good heating effect. It can effectively heat the water circulating in the hot water boiler, and the heat efficiency of the hot water boiler higher than atmospheric 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, in the absence of complex control device, the operation more simple, the complexity of the boiler equipment is also to meet the needs when more users.

First Affiliated Hospital of Bengbu fully implement the national environmental protection policies, strict screening of clean boiler as the supply of medical supplies disinfection and ward heating equipment. Fast boiler with its focus on research and development of clean-type gas boiler two decades of experience in the industry favored. The partnership, to provide fast boiler First Affiliated Hospital of Bengbu Medical College, a WNS20-1.25-YQ one condensing steam boiler, in terms of design, manufacture, installation and other aspects of strict checks to enhance the thermal efficiency of the boiler as well as truly Energy saving and environmental protection.
